Software to Enhance Hands-On Laboratory Experimentation  

NSDL National Science Digital Library

This presentation from MATEC explains the transition from using software to getting hands-on experience in a lab. The laboratory setting in technology related courses is an integral part of the learning experience for the student. It takes the theory that is being learned in the lecture and applies that theory. The text books that are used in the lecture include a copy of either Multi Sim or Electronic Workbench. The software gives the student the ability to "build" the circuits that are under study without the hardware that is found in the lab. The students at Grambling State University are not utilizing the software in the beginning level classes. The students must start utilizing the software earlier in the educational career. To accomplish this, the students are starting to complete the lab assignments with software before going to the lab. By doing this, the students will know what to expect before starting lab. This can and hopefully will remove some confusion that the beginner level circuit student has when constructing a circuit. The next step to improving and enhancing the laboratory experience for the student is to add a computer system to each laboratory station. Each system will contain software and hardware that will connect the test instruments to the computer and perform a multitude of analysis functions. The software that has stimulated some interest is MatLab. MatLab includes curriculum for some of the following: digital signal processing, digital image processing, digital filters, signals and systems, speech processing, computer-controlled systems, applied digital signal processing, dynamic modeling of engineering systems, and continuous-time linear systems. In conclusion, the learning invention for this laboratory is to bring together the lecture and lab through the implementation of software and hardware. This was part of the Learning Invention Labs that MATEC held. Visit the MATEC.org homepage for more information.

Hands-on Activities for understanding Ammonite Sutures  

NSDL National Science Digital Library

There is a lot of primary literature on the origin (and purpose) of complex sutures in ammonites. It is still hotly debated what (if any) benefit complex sutures may have imparted to ammonites. But to start this whole topic (which results in an essay on whether changes in sutures represent a passive or driven trend), I use a set of hands-on exercises that are fun and eye-opening: examining cross-sections through modern nautilus shells, making a play-doh model of an ammonite, and using a Hele-Shaw cell experiment to make complex dendritic shapes. I have found over the years, that students (and my faculty colleagues, too) can easily point out sutures to me on the ammonite fossils in our collection, but they really don't know what they're pointing to (they honestly don't!). So, I split my students (I usually have around 30 in my 200-level Paleobiology course) into teams of three, and we do several things (I do this all in one 4-hour lab, but you could easily do these in separate periods). First, they get an ammonite fossil (always a sediment-filled specimen with the mother of pearl phragmacone at least mostly gone so some of the sutures are clearly visible), and a couple of modern nautilus shells cut in half (I purchase these online from seashellcity.com), and some play-doh (little 2-oz different color tubs I get from Kmart). They have to determine, and then build a model (using play-doh), what they're looking at when they're looking at the ammonite fossils, in particular, the sutures (sans sediment). They are allowed to look stuff up online or in their text. Results are amazing. I've had many teams build a very nice ammonite (usually a tube of play-doh, representing just one chamber with two septal walls at either end of the tube) and then they use a pencil to sketch the sutures on the outside of the phragmacone! I tell them to rethink this and then they work on it more... It's really cool when they finally realize that to make a model of the fossil sutures that they're looking at, they need to peel off their play-doh phragmacone to reveal the sutures (which are just the 1D line at the end of a 2D septal plane) (although the actual 1D 2D thing gets interesting when we delve into the fractal nature of the sutures, see below). Also, the modern nautilus shells beautifully show the difference between growth lines and sutures/septa. So I augment my assessment of their understanding by literally having each student individually trace for me (with their finger) what the suture is on one of the nautilus shells, and what a growth line is (the supplier I use polishes off the periostracum to reveal the mother of pearl with obvious growth lines). I have also taken whole Nautilus shells and buffed off a part of the phragmacone to reveal the edge of the septal wall, which is the exact equivalent of a suture in an ammonite). Then, we run a Hele-Shaw experiment to get viscous fingering (which resembles ammonite sutures). I borrowed this hele-shaw design from the Center for Polymer Studies at Boston University (http://polymer.bu.edu/edu/) Exploring Patterns in Nature. It consists of a pair of ~10-inch square glass plates, one with a hole drilled in it (our Shop makes these for me from standard glass). The hole is a size that fits common plastic tubing (outside diameter) which in turn fits a standard small syringe inside the tubing. The experiment works like this: put a 3 to 5 inch long piece of plastic tube in the hole, but make sure it doesn't stick out the other side (not more than flush), and seal this with some sort of removable sealant; let the sealant stiffen, and clean both plates with windex. Then, on the solid plate, put two stacked thin-section cover slips (I use micro glass little slips) at the corners of the plate, then put the hole-plate with tube up, on top of the cover slips (the inside surfaces need to be very clean), then clip the two plates together with binder clips on each corner. This is a Hele-Shaw cell. Then, with the syringe, inject glycerol between the plates, careful not to put too much in that is squirts out the sides. Then take a syringe with food color in it (darker works better) and inject the food color between the plates. The food coloring injects through the glycerol already in the tube. A beautiful dendrite is created. Compare these with ammonite sutures. You can take it from here. I then stop the exercise and introduce the essay assignment (see uploaded documents).

Hands-on experience with active appearance models  

NASA Astrophysics Data System (ADS)

The aim of this work is to explore the performance of active appearance models (AAMs) in reconstruction and interpretation of bones in hand radiographs. AAM is a generative approach that unifies image segmentation and image understanding. Initial locations for the AAM search are generated by an exhaustive filtering method. A series of AAMs for smaller groups of bones are used. It is found that AAM successful reconstructs 99% of metacarpals, proximal and medial phalanges and the distal 3 cm of radius and ulna. The rms accuracy is better than 240 microns (point-to-curve). The generative property is used (1) to define a measure of fit that allows the models to self-evaluate and chose between the multiple found solutions, (2) to overcome obstacles in the image in the form of rings by predicting the missing part, and (3) to detect anomalies, e.g. rheumatoid arthritis. The shape scores are used as biometrics to check the identity of patients in a longitudinal study. The conclusion is that AAM provides a highly efficient and unified framework for various tasks in diagnosis and assessment of bone related disorders.

Lab Safety and Bioterrorism Readiness Curricula Using Active Learning and Hands-on Strategies as Continuing Education for Medical Technologists  

PubMed Central

Frequent reports of laboratory- (and hospital-) acquired infection suggest a deficiency in safety training or lack of compliance. To assess the need for continuing education (CE) addressing this problem, an original education needs assessment survey was designed and administered to medical technologists (med-techs) in Northeast Ohio. Survey results were used to design a learner-centered training curriculum (for example, Lab Safety and Bioterrorism Readiness trainings) that engaged med-techs in active learning, integrative peer-to-peer teaching, and hands-on exercises in order to improve microbiology safety knowledge and associated laboratory techniques. The Lab Safety training was delivered six times and the Bioterrorism Readiness training was delivered five times. Pre/posttesting revealed significant gains in knowledge and techniques specific to laboratory safety, security, risk assessment, and bioterrorism readiness amongst the majority of med-techs completing the CE trainings. The majority of participants felt that the hands-on exercises met their needs and that their personal laboratory practices would change as a result of the training course, as measured by attitudinal surveys. We conclude that active learning techniques and peer education significantly enhance microbiology learning amongst participating med-techs.

Student Understanding of the Correlation between Hands- on Activities and Computer Visualizations of NMR/MRI  

NSDL National Science Digital Library

This study utilizes the implementation of research-based learning materials designed to teach students about the physics of magnetic resonance imaging (MRI) in a concepts-based introductory-level physics course. A progression of activities using hands-on experiments and computer visualizations leads students through the basics of magnetism and resonance, and finally toward a model of MRI. Here we seek to describe how students understand the basics of resonance and then proceed to make correlations between the hands-on activities and visualizations. Results show that students had fundamental difficulties with the concepts surrounding resonance, and that it appears to have led to a rudimentary understanding of the visualization and how the two tasks were correlated. Based on student responses, we postulate what further scaffolding will be necessary for helping the students make more robust connections and a more comprehensive understanding of the phenomena associated with MRI.

Key partners in the project are NOAO, SPIE-The International Society for Optical Engineering, and the Optical Society of America (OSA). The informal instructional materials created by the project are distributed through science centers nationwide and through the Mathematics, Engineering, Science Achievement Program (MESA) in a number of states, including Arizona, California, Washington, and Maryland. A key part of the project is the involvement, modeled after Project ASTRO, of optics professionals currently engaged in outreach activities and programs. Optics professionals (termed optics resource volunteers) are teamed with MESA and science center educators in implementing the program. These hands-on, high-interest, standards-connected activities and materials provide 6, three-hour-long optics activity modules that can be used in a variety of informal settings. We will describe the techniques used at NOAO to train educators, parents, and optics professionals who will work with the HOO activities as well as the different approaches needed for different informal education programs, ranging from Saturday programs, after-school programs, and science center programs. NOAO is developing the six modules and associated kits as well as competitions that have broad appeal to 12-year olds. Hands-On Optics: Making an Impact with Light (HOO) is a collaborative NSF-funded four-year informal science education program to excite students about science by actively engaging them in optics activities. NOAO is operated by the Association of Universities for Research in Astronomy (AURA), Inc. under cooperative agreement with the National Science Foundation.

Teaching hands-on science activities: Variables that moderate attitude-behavior consistency  

NASA Astrophysics Data System (ADS)

The relationship between prospective elementary teachers' attitudes, subjective norms, and intentions to teach science using hands-on activities at least twice a week during their first year of employment was investigated. The findings suggest that measuring prospective teachers' attitudes toward science cannot adequately predict nor provide a satisfactory explanation of their science teaching behaviors. The findings also provide clear support for two hypotheses derived from Fishbein and Ajzen's theory of reasoned action regarding the predictability of prospective teachers' intentions to teach science from their attitudes and subjective norms.Received: 25 October 1985

Hands-On Astrophysics, 680 Hands at a Time: Lab Activities in Big Classes  

NASA Astrophysics Data System (ADS)

In brief: it is possible to have students do experiments in very large lecture classes. Evaluations show it works. Hands-on science, while traditional in many other disciplines, has not played a large role in astronomy teaching, though many of the concepts we deal with such as heat and pressure can be explored with simple experiments. 340 students in a large lecture class did an experiment with drink bottles, ice, warm water, and baggies to explore the dependence of pressure on temperature. They worked together in approximately 100 groups, working through a teaching sequence which included both a classic demonstration done by the instructor and a hands-on activity where they did the experiment themselves. This activity was carried out in a rather challenging setting: a large lecture room with fixed seats and no plumbing. Handling and disposing of the materials was only modestly more challenging than teaching a regular class. Student evaluations and student performance on exam questions demonstrated that the activity was successful. This research was part of DISCUS (Delaware Innovative Science/Math Collaborative for Undergraduate Success), an initiative supported by the Delaware Department of Public Instruction and the National Science Foundation (DUE-9553787).

Learning ion solid interactions hands-on: An activity based, inquiry oriented, graduate course  

NASA Astrophysics Data System (ADS)

Experimental work, using state of the art instrumentation, is integrated with lectures in a “real life”, learning by discovery approach, in the Ion Solid Interactions graduate/undergraduate course offered by the Department of Physics of the University of Central Florida. The lecture component of the course covers the underlying physical principles, and related scientific and technological applications, associated with the interaction of energetic ions with matter. In the experimental section the students form small groups and perform a variety of projects, experimental and computational, as part of a participative, inquiry oriented, learning process. In the most recent offering of the class, the students deposited a compound semiconductor thin film by dual-gun sputtering deposition, where each group aimed at a different stoichiometry of the same compound (Zn1-xSxOy). Then they analyzed the composition using Rutherford backscattering spectrometry, measured electrical transport properties using Hall effect and conductivity measurements, and determined the band gap using spectrophotometry. Finally the groups shared their results and each wrote a ‘journal-like’ technical article describing the entire work. In a different assignment, each group also developed a Monte Carlo computer program (‘TRIM-like’) to simulate the penetration of ions into a solid, in ion implantation, calculating the stopping cross-sections with approximate models, taught in class, which can be analytically solved. The combination of classroom/laboratory activities is very well received by the students. They gain real life experience operating state of the art equipment, and working in teams, while performing research-like projects, and simultaneously they learn the theoretical foundations of the discipline.

Student responses to a hands-on kinesthetic lecture activity for learning about the oxygen carrying capacity of blood  

NSDL National Science Digital Library

This article describes a new hands-on, or ÃÂkinesthetic,ÃÂ activity for use in a physiology lecture hall to help students comprehend an important concept in cardiopulmonary physiology known as oxygen carrying capacity. One impetus for designing this activity was to address the needs of students who have a preference for kinesthetic learning and to help increase their understanding and engagement during lecture. This activity uses simple inexpensive materials, provides an effective model for demonstrating related pathophysiology, and helps promote active learning. The activity protocol and its implementation are described here in detail. We also report data obtained from student surveys and assessment tools to determine the effectiveness of the activity on student conceptual learning and perceptions. A brief multiple-choice pretest showed that although students had already been introduced to the relevant concepts in lecture, they had not yet mastered these concepts before performing the activity. Two postactivity assessments showed that student performance was significantly improved on the posttest compared with the pretest and that information was largely retained at the end of the course. Survey data showed that one-half of the students stated kinesthetic learning as among their learning preferences, yet nearly all students enjoyed and were engaged in this hands-on kinesthetic activity regardless of their preferences. Most students would recommend it to their peers and expressed a desire for more kinesthetic learning opportunities in the lecture curriculum.

Manipulatives-Based Laboratory for Majors Biology - a Hands-On Approach to Understanding Respiration and Photosynthesis †  

PubMed Central

The first course in our year-long introductory series for Biology majors encompasses four learning units: biological molecules and cells, metabolism, genetics, and evolution. Of these, the metabolism unit, which includes respiration and photosynthesis, has shown the lowest student exam scores, least interest, and lowest laboratory ratings. Consequently, we hypothesized that modeling metabolic processes in the laboratory would improve student content learning during this course unit. Specifically, we developed manipulatives-based laboratory exercises that combined paper cutouts, movable blocks, and large diagrams of the cell. In particular, our novel use of connecting LEGO blocks allowed students to move model electrons and phosphates between molecules and within defined spaces of the cell. We assessed student learning using both formal (content indicators and attitude surveys) and informal (the identification of misconceptions or discussions with students) approaches. On the metabolism unit content exam, student performance improved by 46% over pretest scores and by the end of the course, the majority of students rated metabolism as their most-improved (43%) and favorite (33%) subject as compared with other unit topics. The majority of students rated manipulatives-based labs as very helpful, as compared to non-manipulatives-based labs. In this report, we will demonstrate that students made learning gains across all content areas, but most notably in the unit that covered respiration and photosynthesis.

Teaching chemistry and other sciences to blind and low-vision students through hands-on learning experiences in high school science laboratories  

NASA Astrophysics Data System (ADS)

Students with blindness and low vision (BLV) have traditionally been underrepresented in the sciences as a result of technological and attitudinal barriers to equal access in science laboratory classrooms. The Independent Laboratory Access for the Blind (ILAB) project developed and evaluated a suite of talking and audible hardware/software tools to empower students with BLV to have multisensory, hands-on laboratory learning experiences. This dissertation focuses on the first year of ILAB tool testing in mainstream science laboratory classrooms, and comprises a detailed multi-case study of four students with BLV who were enrolled in high school science classes during 2007--08 alongside sighted students. Participants attended different schools; curricula included chemistry, AP chemistry, and AP physics. The ILAB tools were designed to provide multisensory means for students with BLV to make observations and collect data during standard laboratory lessons on an equivalent basis with their sighted peers. Various qualitative and quantitative data collection instruments were used to determine whether the hands-on experiences facilitated by the ILAB tools had led to increased involvement in laboratory-goal-directed actions, greater peer acceptance in the students' lab groups, improved attitudes toward science, and increased interest in science. Premier among the ILAB tools was the JAWS/Logger Pro software interface, which made audible all information gathered through standard Vernier laboratory probes and visually displayed through Logger Pro. ILAB tools also included a talking balance, a submersible audible light sensor, a scientific talking stopwatch, and a variety of other high-tech and low-tech devices and techniques. While results were mixed, all four participating BLV students seemed to have experienced at least some benefit, with the effect being stronger for some than for others. Not all of the data collection instruments were found to reveal improvements for all of the participating students, but each of the types of data sets provided evidence of benefit for varying subgroups of participants. It is the expectation of the ILAB team that continuing to implement adaptive/assistive technologies for BLV students in science laboratory classrooms will foster enhanced opportunities in science classes and professions.

Hands-On Research School in Africa  

NASA Astrophysics Data System (ADS)

A UNESCO/ICTP-sponsored ``Hands-On Research in Complex Systems'' school was held 1-12 August 2010 in Cameroon for young science faculty in Africa (see handsonresearch.org). Fifty participants from 17 African countries were selected from a pool of more than three hundred applicants. The goal of the school was for the participants to learn to use modern inexpensive instrumentation (such as webcams) and computational techniques to study diverse phenomena in physics, chemistry, biology, and engineering. The hands-on laboratory sessions were led by 12 senior faculty (most from the US); each faculty member brought a graduate student to assist with the teaching. In addition to the laboratory and computational activities, the participants also learned peer instruction teaching methods, developed oral communication skills in interactive sessions, and learned how to do simple inexpensive classroom demonstrations. This talk will show pictures from the Cameroon Hands-On School and will present plans for similar schools in developing countries in Asia, Latin America, and the Mideast.

European Hands-on Universe  

NASA Astrophysics Data System (ADS)

Hands-on Universe is a project born at UC@Berkeley. A project devoted to enrich the teaching of Astronomy within the classroom environment with a different approach, more connected to the new technologies. Its main goals are not only to promote the use of such technologies but also to reawaken on students the taste for STEM (Science, technologies, engineering and math) related issues and also to increase their scientific culture. Eight countries in Europe decided to adopt the method and, funded by MINERVA, formed the European Hands-on Universe. Several resources were produced and a data reduction software developed http://www.euhou.net/.Other European countries are interested and should join this coordinated effort in the near future. At an international level there are 20 countries using this approach. There are plans to develop scientific cooperation among these countries. Pilot scientific research projects in schools are being tested in EU-HOU schools, Russia and USA. There is also a game being developed to be used as a new tool for teaching scientific content in the classroom environment. An effort to develop an international network of scientific / educational collaboration is the next step.

Acoustics Laboratories: Active Noise Control Demo  

NSDL National Science Digital Library

The Virginia Polytechnic Institute and State University Department of Mechanical Engineering offers the Active Noise Control Experiment. The page contains an explanation of the experiment and the download file to carry it out. The experiment demonstrates how active noise control cancels a sound wave by sending a single frequency wave to the right computer speaker, which represents the noise to be canceled, and a control wave of equal amplitude and opposite phase to the left speaker to cancel the noise. Although younger kids will most likely need help from teachers or parents to set up or understand the experiment, the very interesting hands-on activity will be enjoyed by nearly every aged student.

The impact of a hands-on approach to learning visible spectrometry upon students' performance, motivation, and attitudes.  

PubMed

In this paper, the effect of introducing visible spectrometry concepts through hands-on laboratory work upon student learning within four vocational programs are discussed. All together, 118 students, average 18.6 years old, participated in the study. The results showed no correlation between students' motivational components (intrinsic, regulated, and controlled), chemistry self-concept and their achievement on an experiential knowledge test and knowledge gained from this hands-on approach. Statistically significant differences were found for academic achievement among students in a biotechnology technical program (School 1), food processing program (School 2), laboratory biomedicine program (School 3), and a biotechnology general program (School 4). Differences in academic achievement are further reflected in students' perception of particular knowledge gained through their hands-on experiences and in their expressed attitude toward different didactical characteristics. All students, regardless of their study program, highly evaluated the relaxed atmosphere that contributed to their self-confidence in completing their laboratory activities. PMID:23841355

A New Two-Step Approach for Hands-On Teaching of Gene Technology: Effects on Students' Activities During Experimentation in an Outreach Gene Technology Lab  

NASA Astrophysics Data System (ADS)

Emphasis on improving higher level biology education continues. A new two-step approach to the experimental phases within an outreach gene technology lab, derived from cognitive load theory, is presented. We compared our approach using a quasi-experimental design with the conventional one-step mode. The difference consisted of additional focused discussions combined with students writing down their ideas (step one) prior to starting any experimental procedure (step two). We monitored students’ activities during the experimental phases by continuously videotaping 20 work groups within each approach (N = 131). Subsequent classification of students’ activities yielded 10 categories (with well-fitting intra- and inter-observer scores with respect to reliability). Based on the students’ individual time budgets, we evaluated students’ roles during experimentation from their prevalent activities (by independently using two cluster analysis methods). Independently of the approach, two common clusters emerged, which we labeled as ‘all-rounders’ and as ‘passive students’, and two clusters specific to each approach: ‘observers’ as well as ‘high-experimenters’ were identified only within the one-step approach whereas under the two-step conditions ‘managers’ and ‘scribes’ were identified. Potential changes in group-leadership style during experimentation are discussed, and conclusions for optimizing science teaching are drawn.

The US Department of Energy and its national laboratories are a major employer of scientists and engineers and consequently have a strong interest in the development and training of a qualified pool of employment candidates. For many years the DOE and its national laboratories have supported education activities devoted to increasing the number and quality of science and engineering graduates. This is part of the DOE mission because of the critical national need for scientists and engineers and the recognized deficiencies in the education system for science and mathematics training. Though funding support for such activities has waxed and waned, strong education programs have survived in spite of budget pressures. This paper reviews a few of the education programs presently supported at Sandia by the Science and Technology Outreach Department. The US DOE Defense Programs Office and Sandia National Laboratories provide financial support for these education activities.

Outcomes Assessment in a Hands-On Manufacturing Processes Course  

NSDL National Science Digital Library

Industry has consistently identified lack of experience in manufacturing processes as one of the key competency gaps among new engineering graduates. This paper will discuss a laboratory based Manufacturing Processes course that provides hands-on manufacturing experience to students. In addition to standard theoretical concepts, the course uses team-based projects that help students gain hands-on experience with selected manufacturing processes. The projects start with simple components that can be made on a single machine such as a lathe or a mill, and progress to the manufacture and assembly of a fully functional mechanism. This approach introduces students to the issues involved in putting together a non-trivial assembly. Multiple evaluation tools including surveys, focus-groups, and actual observations, were used to determine the effectiveness of the approach used. The results indicate that this is an effective way of addressing industry concerns.

The use of renewable energy technologies is typically thought of as an integral part of creating and sustaining an environment that maximizes the overall quality of life of the Earth`s present inhabitants and does not leave an undue burden on future generations. Sandia National Laboratories has been a leader in developing and deploying many of these technologies over the last two decades. A common but special aspect of all of these activities is that they are all conducted in cooperation with various types of partners. Some of these partners have an interest in seeing these systems grow in the marketplace, while others are primarily concerned with economic benefits that can come from immediate use of these renewable energy systems. This paper describes solar thermal and photovoltaic technology activities at Sandia that are intended to accelerate the commercialization of these solar systems.

Laboratory-tutorial activities for teaching probability  

NASA Astrophysics Data System (ADS)

We report on the development of students’ ideas of probability and probability density in a University of Maine laboratory-based general education physics course called Intuitive Quantum Physics. Students in the course are generally math phobic with unfavorable expectations about the nature of physics and their ability to do it. We describe a set of activities used to teach concepts of probability and probability density. Rudimentary knowledge of mechanics is needed for one activity, but otherwise the material requires no additional preparation. Extensions of the activities include relating probability density to potential energy graphs for certain “touchstone” examples. Students have difficulties learning the target concepts, such as comparing the ratio of time in a region to total time in all regions. Instead, they often focus on edge effects, pattern match to previously studied situations, reason about necessary but incomplete macroscopic elements of the system, use the gambler’s fallacy, and use expectations about ensemble results rather than expectation values to predict future events. We map the development of their thinking to provide examples of problems rather than evidence of a curriculum’s success.

The Adaptive Optics Summer School Laboratory Activities  

NASA Astrophysics Data System (ADS)

Adaptive Optics (AO) is a new and rapidly expanding field of instrumentation, yet astronomers, vision scientists, and general AO practitioners are largely unfamiliar with the root technologies crucial to AO systems. The AO Summer School (AOSS), sponsored by the Center for Adaptive Optics, is a week-long course for training graduate students and postdoctoral researchers in the underlying theory, design, and use of AO systems. AOSS participants include astronomers who expect to utilize AO data, vision scientists who will use AO instruments to conduct research, opticians and engineers who design AO systems, and users of high-bandwidth laser communication systems. In this article we describe new AOSS laboratory sessions implemented in 2006-2009 for nearly 250 students. The activity goals include boosting familiarity with AO technologies, reinforcing knowledge of optical alignment techniques and the design of optical systems, and encouraging inquiry into critical scientific questions in vision science using AO systems as a research tool. The activities are divided into three stations: Vision Science, Fourier Optics, and the AO Demonstrator. We briefly overview these activities, which are described fully in other articles in these conference proceedings (Putnam et al., Do et al., and Harrington et al., respectively). We devote attention to the unique challenges encountered in the design of these activities, including the marriage of inquiry-like investigation techniques with complex content and the need to tune depth to a graduate- and PhD-level audience. According to before-after surveys conducted in 2008, the vast majority of participants found that all activities were valuable to their careers, although direct experience with integrated, functional AO systems was particularly beneficial.

An Undergraduate Laboratory Activity Demonstrating Bacteriophage Specificity†  

PubMed Central

Bacteriophage are among the most diverse and numerous microbes inhabiting our planet. Yet many laboratory activities fail to engage students in meaningful exploration of their diversity, unique characteristics, and abundance. In this curriculum activity students use a standard plaque assay to enumerate bacteriophage particles from a natural sample and use the scientific method to address questions about host specificity and diversity. A raw primary sewage sample is enriched for bacteriophage using hosts in the family Enterobacteriaceae. Students hypothesize about host specificity and use quantitative data (serial dilution and plaque assay) to test their hypotheses. Combined class data also help them answer questions about phage diversity. The exercise was field tested with a class of 47 students using pre- and posttests. For all learning outcomes posttest scores were higher than pretest scores at or below p = 0.01. Average individualized learning gain (G) was also calculated for each learning outcome. Students’ use of scientific language in reference to bacteriophage and host interaction significantly improved (p = 0.002; G = 0.50). Improved means of expression helped students construct better hypotheses on phage host specificity (G = 0.31, p = 0.01) and to explain the plaque assay method (G = 0.33, p = 0.002). At the end of the exercise students also demonstrated improved knowledge and understanding of phage specificity as related to phage therapy in humans (p < 0.001; G = 51).

[Tips to activate your laboratory technologists].  

PubMed

For about two decades, Japanese clinical laboratories have been suffering depression because of the government policy to reduce medical expenditure. Here are my proposals to re-vitalize laboratory science in Japan. (1) Do not keep laboratory technologists stay inside laboratories. Take them out to bedside to show what is going on. Show your technologists' face to medical professionals to experience clinical demand. (2) Invite doctors who cared severely ill patients to your laboratory. Every month my laboratory holds case study meetings using electronic medical records (EMR). Doctors and residents present how laboratory data saved the patient's life. Attending the meeting, laboratory technologists realize how they contributed to improve the patients' destiny. This "case study meeting" with EMR stimulates laboratory technologists to understand they are really one of major players in dramatic story of clinical medicine. (3) Establish a sophisticated industry of biotechnology. Populations of senior citizens are growing in all the developed nations in the world. The healthcare demand is very likely to increase. Because Japan is experiencing "aging society" most drastically, the Japanese could get the first major chance to develop new technologies to improve senior citizens' quality of life. The more government reduce medical expenditure, the less healthcare industry grows up. Without major biotechnology industry, the Japanese have to import expensive technologies from overseas. In conclusion, Japanese society of laboratory medicine, together with related industries should get united to appeal how they can contribute to the nation, in order to obtain appropriate fee, as an investment for future people's health.

RealTime Physics: Active learning laboratory  

NASA Astrophysics Data System (ADS)

Our research shows that student learning of physics concepts in introductory physics courses is enhanced by the use of special guided discovery laboratory curricula which embody the results of educational research and which are supported by the use of the Tools for Scientific Thinking microcomputer-based laboratory (MBL) tools. In this paper we first describe the general characteristics of the research-based RealTime Physics laboratory curricula developed for use in introductory physics classes in colleges, universities and high schools. We then describe RealTime Physics Mechanics in detail. Finally we examine student learning of dynamics in traditional physics courses and in courses using RealTime Physics Mechanics, primarily by the use of correlated questions on the Force and Motion Conceptual Evaluation. We present considerable evidence that students who use the new laboratory curricula demonstrate significantly improved learning and retention of dynamics concepts compared to students taught by traditional methods.

Miniaturization and globalization of clinical laboratory activities.  

PubMed

Clinical laboratories provide an invaluable service to millions of people around the world in the form of quality diagnostic care. Within the clinical laboratory industry the impetus for change has come from technological development (miniaturization, nanotechnology, and their collective effect on point-of-care testing; POCT) and the increasingly global nature of laboratory services. Potential technological gains in POCT include: the development of bio-sensors, microarrays, genetics and proteomics testing, and enhanced web connectivity. In globalization, prospective opportunities lie in: medical tourism, the migration of healthcare workers, cross-border delivery of testing, and the establishment of accredited laboratories in previously unexplored markets. Accompanying these impressive opportunities are equally imposing challenges. Difficulty transitioning from research to clinical use, poor infrastructure in developing countries, cultural differences and national barriers to global trade are only a few examples. Dealing with the issues presented by globalization and the impact of developing technology on POCT, and on the clinical laboratory services industry in general, will be a daunting task. Despite such concerns, with appropriate countermeasures it will be possible to address the challenges posed. Future laboratory success will be largely dependent on one's ability to adapt in this perpetually shifting landscape. PMID:21175379

Hands-on lessons in ergonomics for youth  

SciTech Connect

Ergonomics risk factors apply to everybody. Numerous adults have experienced disabling injuries related to use of computers and other forms of technology. Now children are using technology even more than adults. Increasingly ergonomics risk factors are being recognized as present in the world of children. Outreach to schools and the surrounding community by employers may help protect the future work force. A growing body of researchers believe that children can benefit from the early introduction of ergonomics awareness and preventative measures. While individual representatives of the educational system may embrace the concept of introducing ergonomics into the classroom, a number of barriers can prevent implementation of integrated programs. Some of the barriers to introducing ergonomics in schools have been absence of a tie to educational standards, the existing demands on teaching hours, and the absence of easily executable lesson plans. Ergonomics is rarely included in teacher training and professional ergonomics expertise is needed for the development of a class-based program. As part of Strategic Vision plan for 2025, a National Laboratory identified community outreach and the future workforces as key areas for initiatives. A series of hands-on interactive modules have been developed by professional ergonomics specialists. They are being tested with elementary, middle and high school students. Where possible, the content has been tied to the educational standards in the State of California in the USA. Currently the modules include grip strength, effective breathing, optimal keyboard and mouse positions, optimizing chairs, posture and movement, backpack safety and safe lifting. Each module takes the students through a related activity or experience. An individual worksheet asks them questions about the experience and guides them to consider implications in their activities of daily living. A module on hearing is under development. The goal is to have a toolkit that teachers can use in classrooms with minimal training. The kit will come with lesson plans, including background material, key points, questions and answers, possible homework assignments and references. It will include instructions and worksheets for students as well as the materials needed for each module. A pre- and posttest will be administered to test the awareness and understanding of the principles introduced in through the modules. This interactive session will offer the opportunity to for attendees to participate in some of the modules that have been developed to provide experiential demonstration of ergonomics principles. Attendees will experience ergonomics in action and be able to evaluate the applicability of the process in their own area in the world of ergonomics. The session will consist of 20 minutes introduction, 40 minutes working with the toolkit, finally another 30 minutes for questions or discussion for a total time of 90 minutes.

A MASSive Laboratory Tour. An Interactive Mass Spectrometry Outreach Activity for Children  

NASA Astrophysics Data System (ADS)

It is imperative to fascinate young children at an early stage in their education for the analytical sciences. The exposure of the public to mass spectrometry presently increases rapidly through the common media. Outreach activities can take advantage of this exposure and employ mass spectrometry as an exquisite example of an analytical science in which children can be fascinated. The presented teaching modules introduce children to mass spectrometry and give them the opportunity to experience a modern research laboratory. The modules are highly adaptable and can be applied to young children from the age of 6 to 14 y. In an interactive tour, the students explore three major scientific concepts related to mass spectrometry; the building blocks of matter, charged particle manipulation by electrostatic fields, and analyte identification by mass analysis. Also, the students carry out a mass spectrometry experiment and learn to interpret the resulting mass spectra. The multistage, inquiry-based tour contains flexible methods, which teach the students current-day research techniques and possible applications to real research topics. Besides the scientific concepts, laboratory safety and hygiene are stressed and the students are enthused for the analytical sciences by participating in "hands-on" work. The presented modules have repeatedly been successfully employed during laboratory open days. They are also found to be extremely suitable for (early) high school science classes during laboratory visit-focused field trips.

Calculator Controlled Robots: Hands-On Math and Science Discovery  

NSDL National Science Digital Library

This curriculum includes ten missions and three exploration extensions that provide activities for up to a semester and focus largely on the space exploration theme. It is designed to engage students in hands-on inquiry based learning. It addresses science and technology standards, and specifically focuses on math content and process standards. Although other models will work, the curriculum is geared towards using a Texas Instruments (IT) 83 or 84 series graphing calculator with a Norland research calculator robot. The curriculum can be used in math, science, technology, or after school classes. Students create programs in TI-BASIC to run their robots. Missions are sequentially built on the knowledge of previous activities. Step-by-step programming instructions are provided in the first missions, gradually leading students to create their own programs in later missions. Students use and apply math and science concepts to direct their robots through a variety of challenges. In addition to the detailed activities, teachers are given opportunities to draw on their studentsâ hands-on experience to reach a deeper understanding of mathematical concepts. Several open-ended questions and extension activities are included to encourage potential scientists, engineers, mathematicians, and computer programmers to explore their fields.

The Hands-On Universe Project  

NASA Astrophysics Data System (ADS)

Hands-On Universe (HOU) is a slowly but steadily growing international endeavor that teaches students and teachers modern astronomy through the acquisition, measurement, and analysis of real images from either the International Virtual Observatory or a developing network of small robotic telescopes. This intrinsically global effort shares data, teachers, scientists, students, telescope sites, lesson plans, teacher training strategies, software, collaborative tools, and other resources. Such resources can be spread both ubiquitously and effectively through modern web-based technologies and traditional means. Astronomy has proven to be a superb mechanism to engender and support worldwide collaboration and cooperation; global HOU currently has embraced collaborators from six continents, and is endeavoring to build telescope resources in Antarctica. HOUer's want to work together and find more and more reasons — as the technology becomes congruent — to be optimistic about the future. An underlying raison d'être of HOU is that students can effectively learn science by actually doing science in "real-world" situations — skills of data analysis, experiment planning, collaboration and cooperation. Such skills are necessary for the future well being of students all over the world.

HOU curricula should be published within a year, and we are developing HOU Centers across America and the World, to be on-going and self-sustained sites for teachers to learn how to teach and undertake astronomy in their classrooms. HOU is currently developing museum kiosks for image acquisition and processing in science centers, using an on site robotic telescope, and 0.35 meter telescopes around the world in real time. Over 700 teachers around the United States and another 700 teachers from around the world have taken HOU workshops, and about 2/3 use it in their classrooms. A particularly important development is the HOU collaboration with Johns Hopkins University as part of the usage of National Virtual Observatory and SDSS images and data for education. Such data systems are beginning to result in a flood of data, which will soon overwhelm students and teachers, unless we prepare for this onslaught carefully. HOU has met resonance with other astronomers and educators around the world. Global HOU is thriving, and next years Global HOU meeting will be held at NAOC in Beijing, China. We seek astronomers at this meeting who would be happy to help coach a few students on a paper, using our Collaboratory system!

The nematocidal activity of a broad-spectrum antiparasitic agent, nitazoxanide [( N-(5-nitrothiazol-2-gammal)salicylamide; NTZ], was evaluated in both in vitro and in vivo models using Caenorhabditis elegans, Heligmosomoides polygyrus and Trichinella spiralis. In vitro, NTZ (100 muM) exhibited a low activity against C. elegans and had no effect on embryonation and hatching of H. polygyrus eggs. At concentrations of 100 and 50 muM, the inhibition of excretion/secretion of acetylcholinesterase and acid phosphatase of adult H. polygyrus by NTZ was variable. The in vitro effects of mebendazole (5 muM), albendazole (1 muM) and levamisole (10 muM) were superior to those of NTZ. In mice, NTZ at 1 g/kg proved to be inactive against preadults of T. spiralis whereas mebendazole at 10 mg/kg reduced the worm burden by up to 83%. NTZ at 1 g/kg per day for 3 consecutive days showed a low activity against adults of H. polygyrus (21% reduction). Levamisole, at a single dose of 10 mg/kg, reduced the worm burden by up to 89.9%. The results of this study suggest that NTZ would not have met criteria of a candidate compound. PMID:14574563

Laboratory Directed Research and Development Program Activities for FY 2008.  

SciTech Connect

Brookhaven National Laboratory (BNL) is a multidisciplinary laboratory that maintains a primary mission focus the physical sciences, energy sciences, and life sciences, with additional expertise in environmental sciences, energy technologies, and national security. It is managed by Brookhaven Science Associates, LLC, (BSA) under contract with the U. S. Department of Energy (DOE). BNL's Fiscal year 2008 budget was $531.6 million. There are about 2,800 employees, and another 4,300 guest scientists and students who come each year to use the Laboratory's facilities and work with the staff. The BNL Laboratory Directed Research and Development (LDRD) Program reports its status to the U.S. Department of Energy (DOE) annually in March, as required by DOE Order 413.2B, 'Laboratory Directed Research and Development,' April 19, 2006, and the Roles, Responsibilities, and Guidelines for Laboratory Directed Research and Developlnent at the Department of Energy/National Nuclear Security Administration Laboratories dated June 13, 2006. Accordingly, this is our Annual Report in which we describe the Purpose, Approach, Technical Progress and Results, and Specific Accomplishments of all LDRD projects that received funding during Fiscal Year 2008. BNL expended $12 million during Fiscal Year 2008 in support of 69 projects. The program has two categories, the annual Open Call LDRDs and Strategic LDRDs, which combine to meet the overall objectives of the LDRD Program. Proposals are solicited annually for review and approval concurrent with the next fiscal year, October 1. For the open call for proposals, an LDRD Selection Committee, comprised of the Associate Laboratory Directors (ALDs) for the Scientific Directorates, an equal number of scientists recommended by the Brookhaven Council, plus the Assistant Laboratory Director for Policy and Strategic Planning, review the proposals submitted in response to the solicitation. The Open Can LDRD category emphasizes innovative research concepts with limited management filtering to encourage the creativity of individual researchers. The competition is open to all BNL staff in programmatic, scientific, engineering, and technical support areas. Researchers submit their project proposals to the Assistant Laboratory Director for Policy and Strategic Planning. A portion of the LDRD budget is held for the Strategic LDRD (S-LDRD) category. Projects in this category focus on innovative R&D activities that support the strategic agenda of the Laboratory. The Laboratory Director entertains requests or articulates the need for S-LDRD funds at any time. Strategic LDRD Proposals also undergo rigorous peer review; the approach to review is tailored to the size and scope of the proposal. These Projects are driven by special opportunities, including: (1) Research project(s) in support of Laboratory strategic initiatives as defined and articulated by the Director; (2) Research project(s) in support of a Laboratory strategic hire; (3) Evolution of Program Development activities into research and development activities; and (4) ALD proposal(s) to the Director to support unique research opportunities. The goals and objectives of BNL's LDRD Program can be inferred fronl the Program's stated purposes. These are to (1) encourage and support the development of new ideas and technology, (2) promote the early exploration and exploitation of creative and innovative concepts, and (3) develop new 'fundable' R&D projects and programs. The emphasis is clearly articulated by BNL to be on supporting exploratory research 'which could lead to new programs, projects, and directions' for the Laboratory. We explicitly indicate that research conducted under the LDRD Program should be highly innovative, and an element of high risk as to success is acceptable. To be one of the premier DOE National Laboratories, BNL must continuously foster groundbreaking scientific research. At Brookhaven National Laboratory one such method is through its LDRD Program.

Developing hands-on ergonomics lessons for youth  

SciTech Connect

By the time students are ready to enter the workforce they have been exposed to up to 20 years of ergonomics risk factors. As technology evolves, it provides more opportunities for intensive repetitive motion and with computers, cell phones, personal digital assistants (PDAs), and electronic games. The average student engages in fewer active physical activities, sit stationary in mismatched furniture in schools for hours and carry heavy backpacks. While long-term effects remain to be identified, increasingly ergonomists and others concerned with musculoskeletal health and wellness, see a need for early ergonomics education. This interactive session provides a hands-on approach to introducing ergonomics to students. Although different approaches may effectively introduce ergonomics at even early stages of development, this program was designed for youth at the middle to high school age. Attendees will participate in four activities designed to introduce ergonomics at an experiential level. The modules focus on grip strength, effective breathing, optimizing your chair, and backpack safety. The workshop will include presentation and worksheets designed for use by teachers with minimal ergonomics training. Feedback from the participants will be sought for further refining the usability and safety of the training package.

Active and laboratory experiments in space plasma physics  

NASA Astrophysics Data System (ADS)

This report focuses on active experiments in space as well as laboratory experiments which are directly related to space phenomena. The active experiments involve particle releases in the CRESS and AMPTE missions. Unexpected results such as the motion of the plasma triggered several interesting computer simulations and a laboratory experiment which will be reviewed. Critical Ionization Phenomena will be discussed in this context. A recent release over Arecibo was used to create a “plasma lens” to focus radiation from the HF heater beam. The higher power triggered several nonlinear processes. Advances in plasma sources and diagnostics have made it possible to scale many laboratory experiments. Discussed here are experiments on Alfvén waves generated by a localized source, 3D magnetic field line reconnection, three dimensional magnetized double layers and simulations of a tethered satellite.

A comparison of the effectiveness of hands-on and computer-mediated instruction for learning solubility and solutions at the middle school level  

NASA Astrophysics Data System (ADS)

Previous research in science education has provided evidence that textbook-oriented instruction falls short of achieving desired educational outcomes. In the 1960s, educational reform movements advocated involving students in laboratory experiments with the belief that such hands-on tasks would necessarily lead to learning. In the mid-1980s, the introduction of computers in education provided an alternative to hands-on instruction, but comparisons between hands-on (HO) and computer-mediation (CM) have been scarce and contradictory. Recently, researchers have speculated about the potential benefits of HO versus CM instruction for individuals of different abilities; but few empirical studies have addressed this issue. This research compares immediate and delayed achievement (measured as concept understanding, problem solving, and total learning) and conversations of small groups of students (blocked as high, medium, and low achievers) under each condition. Statistical analysis (2 x 3 randomized block design, Two-Way ANOVA: Instruction method x Prior achievement level) revealed a disordinal interaction between treatment and achievement level: computer instruction resulted in more learning gains for low achievers and hands-on instruction was more effective for high achievers. Hands-on students struggled with procedural demands and obtained less accurate experimental results, making data more difficult to interpret. In contrast, for high achievers, unreliable experimental results seemed to have engendered more discussion among peers and elicited more explanations, which likely led to greater learning gains. In the computer condition, students were relieved of the manipulative demands of real objects, which helped low achievers concentrate on the conceptual aspects of the lesson. The computer facilitated completion of the "experiments" more quickly and hence allowed low achieving students more time to engage with practice tasks, an activity closely monitored and supported by the classroom teacher. My findings have important implications in science education. First, there is no method that works best for all students. Second, these findings may assist the design of school support and gifted programs.

Simulated Medication Therapy Management Activities in a Pharmacotherapy Laboratory Course  

PubMed Central

Objective. To measure the impact of medication therapy management (MTM) learning activities on students’ confidence and intention to provide MTM using the Theory of Planned Behavior. Design. An MTM curriculum combining lecture instruction and active-learning strategies was incorporated into a required pharmacotherapy laboratory course. Assessment. A validated survey instrument was developed to evaluate student confidence and intent to engage in MTM services using the domains comprising the Theory of Planned Behavior. Confidence scores improved significantly from baseline for all items (p < 0.00), including identification of billable services, documentation, and electronic billing. Mean scores improved significantly for all Theory of Planned Behavior items within the constructs of perceived behavioral control and subjective norms (p < 0.05). At baseline, 42% of students agreed or strongly agreed that they had knowledge and skills to provide MTM. This percentage increased to 82% following completion of the laboratory activities. Conclusion. Implementation of simulated MTM activities in a pharmacotherapy laboratory significantly increased knowledge scores, confidence measures, and scores on Theory of Planned Behavior constructs related to perceived behavioral control and subjective norms. Despite these improvements, intention to engage in future MTM services remained unchanged.

Increasing Awareness about Antibiotic Use and Resistance: A Hands-On Project for High School Students  

PubMed Central

Background Health-promoting education is essential to foster an informed society able to make decisions about socio-scientific issues based on scientifically sustained criteria. Antibiotic resistance is currently a major public health issue. Considering that irrational antibiotic use has been associated with the development and widespread of antibiotic resistant bacteria, educational interventions to promote prudent antibiotic consumption are required. Methodology/Principal Findings This study focuses on the outcomes of an interventional program implemented at the University of Porto, Portugal, to promote awareness about antibiotic resistance at high school levels (15–17 year old). The project Microbiology recipes: antibiotics à la carte articulates a set of wet and dry lab activities designed to promote the participants’ understanding of concepts and processes underlying antibiotics’ production and activity, such as the notion of mechanisms of action of antibiotics. Following a mix-method approach based on a pre?/post design, the effectiveness of this project was assessed by gathering data from surveys, direct observation and analysis of artifacts of 42 high school students (aged 15 and 16 years). The results indicate that the participants developed a more comprehensive picture of antibiotic resistance. The project was shown to promote more sophisticated conceptualizations of bacteria and antibiotics, increased awareness about the perils of antibiotic resistance, and enhanced consciousness towards measures that can be undertaken to mitigate the problem. The participants regarded their experiences as enjoyable and useful, and believed that the project contributed to improve their understanding and raise their interest about the issues discussed. Furthermore, there were also improvements in their procedural skills concerning the laboratory techniques performed. Conclusions/Significance This study evidences the possibility of increasing high school students’ awareness about the consequences of antibiotic resistance and the importance of judicious antibiotic use. The findings inform about the educational benefits of incorporating hands-on activities in science education programs.

Dose profile modeling of Idaho National Laboratory's active neutron interrogation laboratory.  

PubMed

A new laboratory has been commissioned at Idaho National Laboratory for performing active neutron interrogation research and development. The facility is designed to provide radiation shielding for deuterium-tritium (DT) fusion (14.1 MeV) neutron generators (2 x 10(8) n/s), deuterium-deuterium (DD) fusion (2.5 MeV) neutron generators (1 x 10(7) n/s), and (252)Cf spontaneous fission neutron sources (6.96 x 10(7) n/s, 30 microg). Shielding at the laboratory is comprised of modular concrete shield blocks 0.76 m thick with tongue-in-groove features to prevent radiation streaming, arranged into one small and one large test vault. The larger vault is designed to allow operation of the DT generator and has walls 3.8m tall, an entrance maze, and a fully integrated electrical interlock system; the smaller test vault is designed for (252)Cf and DD neutron sources and has walls 1.9 m tall and a simple entrance maze. Both analytical calculations and numerical simulations were used in the design process for the building to assess the performance of the shielding walls and to ensure external dose rates are within required facility limits. Dose rate contour plots have been generated for the facility to visualize the effectiveness of the shield walls and entrance mazes and to illustrate the spatial profile of the radiation dose field above the facility and the effects of skyshine around the vaults.

Invention activities as preparation for learning laboratory data handling skills  

NASA Astrophysics Data System (ADS)

Undergraduate physics laboratories are often driven by a mix of goals, and usually enough of them to cause cognitive overload for the student. Our recent findings align well with studies indicating that students often exit a physics lab without having properly learned how to handle real data. The value of having students explore the underlying structure of a problem before being able to solve it has been shown as an effective way to ready students for learning. Borrowing on findings from the fields of education and cognitive psychology, we use ``invention activities'' to precede direct instruction and bolster learning. In this talk I will show some of what we have learned about students' data handling skills, explain how an invention activity works, and share some observations of successful transfer.

In vivo neutron activation facility at Brookhaven National Laboratory  

SciTech Connect

Seven important body elements, C, N, Ca, P, K, Na, and Cl, can be measured with great precision and accuracy in the in vivo neutron activation facilities at Brookhaven National Laboratory. The facilities include the delayed-gamma neutron activation, the prompt-gamma neutron activation, and the inelastic neutron scattering systems. In conjunction with measurements of total body water by the tritiated-water dilution method several body compartments can be defined from the contents of these elements, also with high precision. In particular, body fat mass is derived from total body carbon together with total body calcium and nitrogen; body protein mass is derived from total body nitrogen; extracellular fluid volume is derived from total body sodium and chlorine; lean body mass and body cell mass are derived from total body potassium; and, skeletal mass is derived from total body calcium. Thus, we suggest that neutron activation analysis may be valuable for calibrating some of the instruments routinely used in clinical studies of body composition. The instruments that would benefit from absolute calibration against neutron activation analysis are bioelectric impedance analysis, infrared interactance, transmission ultrasound, and dual energy x-ray/photon absorptiometry.

Elementary education majors experience hands-on learning in introductory biology.  

PubMed

Faculty members from the University of South Dakota attended the Curriculum Reform Institute offered by the University of Wisconsin at Oshkosh, WI, during the summer of 2002 to design a course sequence for elementary education majors that better meets their needs for both content and pedagogy based on the science education standards. The special section of introductory biology that resulted from this workshop is designed to use laboratories and activities that either help students learn major concepts in the life sciences or model how to teach these concepts to their future K-8 students. This study describes how the active, hands-on learning opportunity for preservice teachers with its emphasis on both content and performance-based assessment was implemented in an introductory biology course for elementary education majors during the spring of 2004. During the initial offering of this course, student perceptions about what helped them to learn in the special section was compared with their nonscience major peers in the large lecture-intensive class that they would have taken. Each group of students completed early and late web-based surveys to assess their perceptions about learning during the courses. After the completion of the course, students in the special section appreciated how the relevance of science and conducting their own scientific experimentation helped them learn, enjoyed working and studying in small groups, valued diverse class time with very little lecture, were more confident in their abilities in science, and were more interested in discussing science with others. This course format is recommended for science classes for preservice teachers. PMID:17108247

School of Rock: An Ocean-going, Hands-on Research Expedition for Earth and Ocean Science Teachers  

NASA Astrophysics Data System (ADS)

The Integrated Ocean Drilling Program (IODP) - United States Implementing Organization (USIO) took advantage of a 16-day break between scientific operations to carry out a seagoing pilot educator workshop on board the JOIDES Resolution during a transit from Victoria, B.C., Canada, to Acapulco, Mexico. During this workshop, 10 educators from all across the United States were mentored and taught by scientists who are actively engaged in IODP research, the USIO Education Director, and staff. In addition, shipboard technical staff provided guidance and content related to hands-on laboratory activities. The pilot program provided the educators with an opportunity to participate in a seagoing experience on a scientific drilling research vessel and conduct a series of research activities similar to those that take place during regular scientific drilling expeditions. The workshop allowed educators to increase their knowledge of IODP and scientific methods as borne out through ocean drilling (proposals, drilling, lab analysis, data acquisition, postcruise activities) as well as knowledge of mid-ocean ridges, composition and structure of the oceanic crust, seafloor spreading, paleoceanography, paleomagnetism, and sedimentology. The workshop participants translated the scientific results into useful teaching resources by developing a suite of new discovery-based activities related to ocean drilling research that will undergo classroom testing by workshop participants. Over the school year the educators will help disseminate IODP science education by conducting at least two teacher workshops based on this seagoing experience, enhanced scientific knowledge gained from participating in the workshop, and the new activities developed en route.

A Fourier Optics and Wavefront Sensing Laboratory Activity  

NASA Astrophysics Data System (ADS)

The Fourier optics activity is designed to enable students to observe and experiment with the diffraction of light. The goal of this activity is for the students to be able to use the principles of Fourier transforms in explanations of diffraction phenomena. We developed a series of tiered goals to accommodate participants with a large range of optics experience in the Adaptive Optics Summer School at UC Santa Cruz. This activity is conducted in two stages. In the first stage, students investigate a series of basic wave optics phenomena with the laboratory setup; in the later stage students have the additional options of constructing a Shack-Hartmann wavefront sensor or a high contrast imaging system. The tabletop optical setup for the activity consists of a computer-controlled detector illuminated by a laser source, and a set of lenses and apertures. Students work in small groups to investigate the relationships between the shape of the limiting aperture and the resulting far-field diffraction pattern. In addition, students examine how phase errors in the pupil affect the point spread function, and how they alter the signal received by a Shack-Hartmann sensor. Software tools are provided for comparing experimental results with simulations.

The Fermi Bubbles: Possible Nearby Laboratory for AGN Jet Activity  

NASA Astrophysics Data System (ADS)

The two giant gamma-ray bubbles discovered by the Fermi Gamma-ray Space Telescope are nearly symmetric about the Galactic plane, suggesting some episode of energy injection from the Galactic center, such as a nuclear starburst or active galactic nucleus (AGN) jet activity. Using three-dimensional magnetohydrodynamic simulations that self-consistently include the dynamical interaction between cosmic rays (CR) and thermal gas, and anisotropic CR diffusion along magnetic field lines, we show that the key characteristics of the observed bubbles can be successfully reproduced by a recent jet activity from the central AGN. This implies that the Fermi bubbles could be a unique laboratory for studying AGN jet-inflated bubbles. Our simulations allow us to generate maps of the distribution of the magnetic field, radio polarization, and synchrotron, X-ray, and gamma-ray emission. While the source of pressure support of extragalactic AGN bubbles is still poorly known due to observational limitations, we are able to derive constraints on the composition of the Fermi bubbles by comparing our model predictions with the spatially resolved gamma-ray bubble and microwave haze observations.

``Hands on'' Experiments in Integrated Approach in Teaching Physics and Chemistry  

NASA Astrophysics Data System (ADS)

The accelerated technological development, which represents a natural frame of growing up of young generations, in parallel with the decline of their interest in physics, chemistry and natural sciences in general, imposes an enhanced in teaching process. In integrated approach in teaching of physics and chemistry, ``Hands on'' experiments are of multiple significance. They enable active participation of the learners in the teaching process, enable them to realize that science is all around us, and that it plays an essential role in the contemporary world. On the other hand, one of the possibilities of science popularization is through the implementation of ``Hands on'' experiments into the educational process. In this work the authors propose how to realize some subjects in teaching about heat in integrated approach of physics and chemistry and how to implement some simple experiments into the teaching process.

Teaching radio astrophysics the hand-on way  

NASA Astrophysics Data System (ADS)

Astronomy and space sciences have always been instrumental in attracting young students to physical sciences. While the lectures/demonstrations and exhibitions pertaining to space sci-ences capture the imagination of young students, these alone are not sufficient to induce them to join scientific research. In countries like India, where a large number of students take to physical sciences for under-graduate education, complex sociological factors are key issues in translating this large body of students to potential researchers. While lectures and exhibition lead to an increase in scientific awareness for these students, these do not give a feel for scien-tific research and bridge the gap between high school/college science education and high end research. In this context, a hands-on approach to astronomy education, in science research environments or closely connected to scientific institutions, offers a promising alternative. This approach has been used in optical astronomy, where inexpensive small telescopes are available, often coupling a vast network of amateur astronomy clubs to leading astronomy institutes. The non-visual and relatively more technical nature of radio astronomy has limited a similar approach in past for connecting students to space sciences using radio waveband. The tech-nological explosion in communication industry and radio connectivity in the last decade along with an expansion in engineering education makes this possible now using a hands-on approach in teaching radio astrophysics. In this presentation, the sociological factors affecting the student choice are discussed followed by a review of the efforts to bridge the above mentioned gap by various groups in the world in the last decade with a view to enumerate the best practices in a hands-on approach. A program using this approach at National Center for Radio Astrophysics is described, where the students are exposed to simple hands-on radio astronomy experiments such as spectral line observations of neutral hydrogen from Milky Way and solar flux moni-toring. Such experiments are also useful to familiarize the students with astronomy jargon, which many times becomes an impediment in connecting them with research. This program also aims to develop low cost radio telescopes with involvement of engineering students and the presentation aims at sharing the experience in this program. Future possibilities bridging the gap between the research institutions, such as ours, and the student population at large are also discussed.

An investigation of the impact of selected prereading activities on student content learning through laboratory activities  

NASA Astrophysics Data System (ADS)

This study investigated whether two prereading activities impacted student learning from hands-on science activities. The study was based on constructivist learning theory. Based on the work of Piaget, it was hypothesized that students who activated prior knowledge would learn more from the activities. Based on the work of Vygotsky it was hypothesized that students who talk more and write more would learn more from the activity. The K-W-L chart and anticipation guide strategies were used with eighth grade students at Graves Middle School in Whittier, California before learning about levers and convection currents. D. M. Ogle (1986) created the three-column K-W-L chart to have students activate prior knowledge. In the first column, the students write what they already know about a subject, in the second column, the students write what they want to know about the subject, and the students complete the third column after learning about a subject by writing answers to the questions that they asked in the second column. Duffelmeyer (1994) created the anticipation guide based on Herber's (1978) reasoning guide. In the anticipation guide, the teacher creates three or four sentences that convey the major ideas of the topic and the students either agree or disagree with the statements. After learning about the topic, students revisit their answers and decide if they were correct or incorrect and they must defend their choices. This research used the Solomon (1947) four-square design and compared both the experimental groups to a control group that simply discussed the concepts before completing the activity. The research showed no significant difference between the control group and either of the treatment groups. The reasons for the lack of significant differences are considered. It was hypothesized that since the students were unfamiliar with the prereading activities and did not have much experience with using either writing-to-learn or talking-to-learn strategies, the short-term intervention was not effective. Directions for future study are considered.

Inquiry-Based Laboratory Activities in Electrochemistry: High School Students' Achievements and Attitudes  

NASA Astrophysics Data System (ADS)

This study aimed to investigate the effects of inquiry-based laboratory activities on high school students' understanding of electrochemistry and attitudes towards chemistry and laboratory work. The participants were 62 high school students (average age 17 years) in an urban public high school in Turkey. Students were assigned to experimental ( N = 30) and control groups ( N = 32). The experimental group was taught using inquiry-based laboratory activities developed by the researchers and the control group was instructed using traditional laboratory activities. The results of the study indicated that instruction based on inquiry-based laboratory activities caused a significantly better acquisition of scientific concepts related to electrochemistry, and produced significantly higher positive attitudes towards chemistry and laboratory. In the light of the findings, it is suggested that inquiry-based laboratory activities should be developed and applied to promote students' understanding in chemistry subjects and to improve their positive attitudes.

Current radar responsive tag development activities at Sandia National Laboratories.  

SciTech Connect

Over the past ten years, Sandia has developed RF radar responsive tag systems and supporting technologies for various government agencies and industry partners. RF tags can function as RF transmitters or radar transponders that enable tagging, tracking, and location determination functions. Expertise in tag architecture, microwave and radar design, signal analysis and processing techniques, digital design, modeling and simulation, and testing have been directly applicable to these tag programs. In general, the radar responsive tag designs have emphasized low power, small package size, and the ability to be detected by the radar at long ranges. Recently, there has been an interest in using radar responsive tags for Blue Force tracking and Combat ID (CID). The main reason for this interest is to allow airborne surveillance radars to easily distinguish U.S. assets from those of opposing forces. A Blue Force tracking capability would add materially to situational awareness. Combat ID is also an issue, as evidenced by the fact that approximately one-quarter of all U.S. casualties in the Gulf War took the form of ground troops killed by friendly fire. Because the evolution of warfare in the intervening decade has made asymmetric warfare the norm rather than the exception, swarming engagements in which U.S. forces will be freely intermixed with opposing forces is a situation that must be anticipated. Increasing utilization of precision munitions can be expected to drive fires progressively closer to engaged allied troops at times when visual de-confliction is not an option. In view of these trends, it becomes increasingly important that U.S. ground forces have a widely proliferated all-weather radar responsive tag that communicates to all-weather surveillance. The purpose of this paper is to provide an overview of the recent, current, and future radar responsive research and development activities at Sandia National Laboratories that support both the Blue Force Tracking and Combat ID application.

Hands-On Optics: An Informal Education Program for Exploring Light and Color  

NASA Astrophysics Data System (ADS)

Hands-On Optics (HOO) is a collaborative four-year program to create and sustain a unique, national, informal science education program to excite students about science by actively engaging them in optics activities. It will reach underrepresented middle school students in after-school programs and at hands-on science centers nationwide. Project partners with NOAO are SPIE-The International Society for Optical Engineering, the Optical Society of America (OSA), and the Mathematics, Engineering, Science Achievement Program (MESA) of California. This program builds on the 2001 National Science Foundation planning grant (number ESI-0136024), Optics Education - A Blueprint for the 21st Century, undertaken to address the disconnect between the ubiquity of optics in everyday life and the noticeable absence of optics education in K-12 curricula and in informal science education. NOAO - with expertise in teaching optics, developing optics kits, and in science-educator partnerships is designing the HOO instructional materials by adapting well-tested formal education activities on light, color, and optical technology for the informal setting. These hands-on, high-interest, standards-connected activities and materials serve as the basis for 6, three-hour-long optics activity modules that will be used in informal education programs at 23 HOO host sites. NOAO also will train the educators, parents, and optics professionals who will work in teams to lead the HOO activities. A key component of the project will be the optics professionals from the two optical societies who currently are engaged in outreach activities and programs. Optics professionals will serve as resource agents teamed with science center and MESA educators, a model very successfully used by the Astronomical Society of the Pacific's Project ASTRO. The six modules and associated challenges and contests address reflection from one or many mirrors, image formation, colors and polarization, ultraviolet and infrared phenomena, and communication over a beam of light. Challenges and contests have also been created to augment the six modules. The Hands On Optics Project is funded by the National Science Foundation ISE program.

Laboratory Directed Research and Development Program Activities for FY 2007.  

SciTech Connect

Brookhaven National Laboratory (BNL) is a multidisciplinary laboratory that carries out basic and applied research in the physical, biomedical, and environmental sciences, and in selected energy technologies. It is managed by Brookhaven Science Associates, LLC, (BSA) under contract with the U. S. Department of Energy (DOE). BNL's Fiscal year 2007 budget was $515 million. There are about 2,600 employees, and another 4,500 guest scientists and students who come each year to use the Laboratory's facilities and work with the staff. The BNL Laboratory Directed Research and Development (LDRD) Program reports its status to the U.S. Department of Energy (DOE) annually in March, as required by DOE Order 413.2B, 'Laboratory Directed Research and Development', April 19, 2006, and the Roles, Responsibilities, and Guidelines for Laboratory Directed Research and Development at the Department of Energy/National Nuclear Security Administration Laboratories dated June 13, 2006. In accordance this is our Annual Report in which we describe the Purpose, Approach, Technical Progress and Results, and Specific Accomplishments of all LDRD projects that received funding during Fiscal Year 2007. The goals and objectives of BNL's LDRD Program can be inferred from the Program's stated purposes. These are to (1) encourage and support the development of new ideas and technology, (2) promote the early exploration and exploitation of creative and innovative concepts, and (3) develop new 'fundable' R&D projects and programs. The emphasis is clearly articulated by BNL to be on supporting exploratory research 'which could lead to new programs, projects, and directions' for the Laboratory. We explicitly indicate that research conducted under the LDRD Program should be highly innovative, and an element of high risk as to success is acceptable. In the solicitation for new proposals for Fiscal Year 2007 we especially requested innovative new projects in support of RHIC and the Light Source and any of the Strategic Initiatives listed at the LDRD web site. These included support for NSLS-II, RHIC evolving to a quantum chromo dynamics (QCD) lab, nanoscience, translational and biomedical neuroimaging, energy and, computational sciences. As one of the premier scientific laboratories of the DOE, BNL must continuously foster groundbreaking scientific research. At Brookhaven National Laboratory one such method is through its LDRD Program. This discretionary research and development tool is critical in maintaining the scientific excellence and long-term vitality of the Laboratory. Additionally, it is a means to stimulate the scientific community and foster new science and technology ideas, which becomes a major factor in achieving and maintaining staff excellence and a means to address national needs within the overall mission of the DOE and BNL.

Key Aspects of the Implementation of Optional Subject ``Hands on-discovering of the World'' in Teaching Practice of the West-Ba?ka District in Serbia  

NASA Astrophysics Data System (ADS)

All over the world a number of initiatives have been started which offer new models for improving the quality of science teaching. One of the leading initiatives is Hands on which in 2003, included the introduction of the optional subject ``Hands on-discovering of the world'' into the first four grades of primary schools in Serbia. Five years after it had been introduced in our educational system, the analysis was carried out in order to determine the extent and the way this subject was taught in primary schools of the West-Backa District. The specially designed questionnaire was conducted on the sample of 137 teachers from 16 schools. The analysis shows that this subject is not present enough in teaching practice. This is the case because parents and pupils are poorly informed and mostly uninterested but also because of the widespread mistake that the subject requires special equipment and laboratories. When we analyzed the experience of teachers, we discovered that they were not familiar enough either with its basic principles or with recommended way of realization mainly because of the fact that most teachers did not attend science seminars nor they used appropriate professional literature. In order to increase the presence of this optional subject in teaching practice and to educate teachers for its more quality presentation, it is necessary for teachers to attend seminars about science teaching and to actively cooperate with science teachers at their schools as well as at related colleges.

A laboratory activity on the eddy current brake  

NASA Astrophysics Data System (ADS)

The aim of this paper is to introduce a simple and low-cost experimental setup that can be used to study the eddy current brake, which considers the motion of a sliding magnet on an inclined conducting plane in terms of basic physical principles. We present a set of quantitative experiments performed to study the influence of the geometrical and electromagnetic properties of the magnet on the magnetic drag force. This video-based experiment is ideal for the study of kinematic graphs and the application of Newton's laws. Video motion analysis software enables students to make precise measurements of the magnet's position at incremental times during its motion, thus allowing them to quantify electromagnetic induction phenomena. The equipment needed for this experiment and data collection software are present in most physics teaching laboratories or are inexpensive and available.

Hands-On TAROT: Intercontinental Use of the TAROT for Education and Public Outreach  

NASA Astrophysics Data System (ADS)

The TAROT telescope has for primary goal the search for the prompt optical counterpart of cosmic Gamma-Ray Bursts. It is a completely autonomous 25cm telescope installed near Nice (France), able to point to any location of the sky within 1-2 seconds. The control, scheduling, and data processing activities are completely automated. In addition to its un-manned modes, we added recently the possibility to control the telescope remotely, as a request of the ``Hands-On Universe'' (HOU) program of using automatic telescopes for education and public outreach. To this purpose we developed a simple control interface. A webcam was installed to visualize the telescope. Access to the data is possible through a web interface. The images can be processed by the HOU software, a program specially suited for use within the classroom. We used these feature during the open days of the University of California Berkeley and the Astronomy Festival of Fleurance (France). We plan regular use for an astronomy course of the Museum of Tokyo, as well as for French schools. Not only does Hands-On TAROT gives the general public access to professional astronomy, it is also a more general tool to demonstrate the use of a complex automated system, the techniques of data processing and automation. Last but not least, through the use of telescopes located in many countries over the globe, a powerful and genuine cooperation between teachers and children from various countries is promoted, with a clear educational goal.

Geoelectrical signatures of microbial activity: A laboratory tank investigation  

NASA Astrophysics Data System (ADS)

Experiments in a 2D static tank (dimensions 145 cm x 85 cm x 6 cm) were performed to assess the effectiveness of various geo-electrical methods (induced polarization [IP], resistivity [R], self potential [SP], electrodic potential [El]) to monitor microbial activity. The tank was filled with coarse sand and saturated with water from the river Lagan (Belfast, UK) diluted with tap water (20:80 ratio). The river water was used to 'seed' microbial activity in the tank. We created 2 separate zones of activity by applying a layer of Hydrogen Release Compound (HRC) and a layer of Oxygen Release Compound (ORC) at the bottom and the middle of the tank respectively. This design aimed to simulate conditions at the oxic - anoxic interface commonly found in contaminated groundwaters. We recorded IP and R signals using a network of 32 electrodes on one side of the tank; the same electrodes were used for El measurements; we recorded the SP signals with 9 Petiau electrodes located at the top of the tank. El measurements provide us with detailed information on the spatial and temporal Eh evolution in the tank, as a result of microbial activity (indirect evidence), whereas the SP measurements are related directly to the microbial activity (direct evidence); IP and R measurements were aimed to provide additional insight on microbial induced fluid conductivity / porosity / mineralization processes expected to occur under our experimental conditions. The combination of El and SP measurements is shown to be a powerful approach for remote monitoring of microbial activity in the subsurface; the methods supplement each other to more accurately describe the microbial evolution. Furthermore , the interpretation of the subsurface conditions are improved when constrained by the fluid conductivity and mineralization changes inferred by the IP and R measurements. The results of this work suggest that a combination of different geo-electrical methods enhance the subsurface monitoring of microbial activity.

A Large-Scale Assessment of Introductory Physics Courses: Development of Laboratory Activities  

NASA Astrophysics Data System (ADS)

While there has long been a general consensus among science researchers and educators that practical work is an essential component of teaching science, there is little agreement about the purposes of undergraduate laboratory courses. The aims of these courses are often manifold and confusingly combined. As part of the reform taking place in the undergraduate physics curriculum at Texas Tech University, we aim to develop laboratory activities which promote students' understanding of the nature of measurement and uncertainty, while providing opportunities for students to apply learned concepts to new situations through experiment and observation. Our goal is to construct a laboratory curriculum which reflects science practice, and highlights the nature of science and the process of scientific inquiry. The activities are based on the probabilistic approach to measurement, and a modelling framework for physics teaching and learning. The development of these activities will be discussed; and examples from an introductory calculus-based laboratory course will be presented.

Student Understanding of Chromatography: A Hands-On Approach  

NASA Astrophysics Data System (ADS)

This exercise sets up a collaborative activity that challenges students to develop a chromatographic solvent with the appropriate polarity to separate leaf chlorophyll and anthocyanin pigments by TLC. The suggested activity has been tested with both high-school advanced-chemistry students and with undergraduate students in an introductory biochemistry class. It includes a demonstration introducing the basic principles of partitioning and differential distribution based on solubility. For the student activity, the materials to be used are leaves of the variegated Coleus plant, plastic-backed silica TLC plates, 2-propanol, acetone, and methanol. Students may work collaboratively within a set of boundary parameters to optimize the chromatographic solvent through a series of rapid iterations of chromatography.

Teaching a Hands-on Biomedical Instrumentation Course Jointly at Two Institutions  

NSDL National Science Digital Library

The Biomedical Engineering (BME) department at the University of North Carolina at Chapel Hill (UNC) has taught a microcontroller applications course for many years. In this course, students learn how to program a microcontroller and interface it to hardware to develop biomedical instruments, such as a heart rate monitor and temperature sensor. With the development of a joint BME department at UNC and North Carolina State University (NCSU), the faculty realized that it would be beneficial to teach the class jointly at NCSU, as the students there needed more hands-on opportunities in biomedical instrumentation. The class meets twice each week using videoconferencing equipment. Both classrooms are equipped with multiple screens for viewing video of the distant location, as well as sharing a computer desktop. Students work in the laboratory on weekly homework assignments and miniprojects, in which they program microcontrollers and develop biomedical instruments. The laboratories on each campus have equivalent hardware setups, as well as videoconferencing equipment so that faculty can help the students remotely. The primary teacher for this class is based at UNC, and he occasionally travels to NCSU to work with those students directly. In addition, a faculty member at NCSU is present for most classes, and he is available to provide assistance to the NCSU students outside of class. In this manner, the NCSU students have opportunities to get in-person help from a faculty member. Feedback on this experience was measured at mid-semester and at the end of the semester. This experience can serve as a model for teaching courses jointly at our universities as well as elsewhere.

Classes Azur Astro Espace International Hands-on Space Experience  

NASA Astrophysics Data System (ADS)

Created in 1994 in the wake of the closure of the Space Camp of Patrick Baudry in Cannes, Classes Azur Astro Espace (AAE) provide a world's unique combination of space and astronomy courses, as given by active and retired professionals of two of the best space and astronomical facilities extant: Alcatel Space in Cannes and Observatoire de la Côte d'Azur (OCA) in Nice, Grasse and Caussols. Fifteen space modules, of 30 to 60 minutes each, have been established, giving simple and clear explanations on launchers, satellites, their applications, their development, together with an historical background. Basic experiments are included, such as an unique small catapult to explain gravity, or more classical water rockets. The basic AAE sojourn extends over 3 days: one day for space (including a visit of Alcatel Space, the biggest satellite manufacturer outside the US and Russia), one day for astronomy (including a visit of the biggest observatory in Europe) and one day à-la-carte (Côte d'Azur offers much, such as the Oceanographic Museum in Monaco). More and more groups are adding a fourth day, with a visit to the nice old village of Perinaldo in Italy, where famous astronomer Cassini was born. Lycée de Cachan, near Paris, even takes 12-day sojourns every year. The public has been extremely wide, from age 5 to 70, from students to enthusiasts. Coming initially all over from France, participants now include since 2001 German and Italian pupils and teachers. In 2001 also, ESA came in the shape of a Space Camp. ISU's Master of Space Studies participates to a shortened version of AAE every even-year. Up to the end of 2001, 62 classes with 2,025 participants from 20 countries had thus come to enjoy space education on Côte d'Azur. Such success is due in no small part to the very attractive price and flexibility of these activities, notably thanks to the support of ESA, CNES, Rectorat d'Académie de Nice, Conseil Général des Alpes-Maritimes, Ville de Cannes, AAAF, TDF, Alcatel Space and OCA.

NASA Astrophysics Data System (ADS)

As announced in the paper presented in Toulouse, a trinational teacher training program addressing school teachers from France, Germany and Italy on teaching foreign languages together with science and history through Space related projects has been implemented and launched successfully. Supported by the French Ministry of Education (Académie de Nice), the bigovernmental French-German Youth Office (Office franco- allemand pour la Jeunesse) and the European Space Agency the first session was held in Cannes in October 2001 and brought together 36 language, science and history teachers, 12 from each country. Through different workshops, presentations and visits this five-day training encounter initiated the participants with Space activities and exploration as well as offering them back-up information on astronomy. It gave them furthermore the opportunity of improving their linguistic skills and of exchanging their teaching experience. The program was highly welcomed by all the participants who will meet this year in Germany for the second session devoted to establishing together bi- or trinational projects for future class encounters based on the same subjects. My paper will deal with the results of the program which have been beyond expectation and will encourage us to continue this pluridisciplinary approach of language &science teaching and extend it to other language combinations.

Improving chemical education from high school to college using a more hands-on approach  

NASA Astrophysics Data System (ADS)

In this work, various alternative teaching methods and activities for chemical education are developed, presented, and evaluated. In the first study, an original hands-on activity using LEGO® blocks to model ionic chemical formulas is presented together with quantitative and qualitative data regarding its educational effectiveness. Students explore cation to anion ratios using LEGO® blocks to represent trivalent, divalent and monovalent cations and anions. High school chemistry students who participated in the LEGO® lab showed significantly higher post-test scores than other students. The second study grows out of the creation of a computational lab module that is shown to significantly increase student learning in the subject of molecular orbital theory in first semester college General Chemistry. The third and final study presented is a course redesign project for college CHEM 1100, Preparation for General Chemistry. In this project the classroom is “flipped”. Students watch video lectures at home, and spend class time working with peers and the instructor on problem solving activities. The results presented here are one of the first quantitative studies showing the effectiveness of “flipping the classroom”. Students who were taught using the Reverse-Instruction (RI) method had significantly higher success in both the Preparation for General Chemistry course and traditionally taught General Chemistry I the following semester.

Characterization of the protease activity of detergents: laboratory practicals for studying the protease profile and activity of various commercial detergents.  

PubMed

Detergent enzymes account for about 30% of the total worldwide production of enzymes and are one of the largest and most successful applications of modern industrial biotechnology. Proteases can improve the wash performance of household, industrial, and institutional laundry detergents used to remove protein-based stains such as blood, grass, body fluids, and food soils. This article describes two easy and cheap laboratory exercises to study the presence, profile, and basic enzymology of detergent proteases. These laboratory practicals are based on the determination of the detergent protease activity of various commercial detergents using the N-succinyl-L-alanyl-L-alanyl-L-prolyl-L-phenylalanine p-nitroanilide method and the bovine serum albumin degradation capacity. Students are also required to elucidate the enzymatic subtype of detergent proteases by studying the inhibitory potential of several types of protease inhibitors revealed by the same experimental methodology. Additionally, the results of the exercises can be used to provide additional insights on elementary enzymology by studying the influence of several important parameters on protease activity such as temperature (in this article) and the influence of pH and effects of surfactants and oxidizers (proposed). Students also develop laboratory skills, problem-solving capacities, and the ability to write a laboratory report. The exercises are mainly designed for an advanced undergraduate project in the biochemistry and biotechnology sciences. Globally, these laboratory practicals show students the biotechnological applications of proteases in the detergent industry and also reinforce important enzymology concepts. PMID:21774056

A Laboratory Experiment Investigating Different Aspects of Catalase Activity in an Inquiry - Based Approach  

NASA Astrophysics Data System (ADS)

The action of the enzyme catalase on aqueous hydrogen peroxide to generate oxygen gas is a well-established demonstration (1-3). Catalase is typically obtained by aqueous extraction of a potato, and the potato extract is mixed together with 3% hydrogen peroxide. The oxygen that is produced can be collected over water. Variations on the procedure can demonstrate the dependence of catalytic activity on temperature or the presence of inhibitors (1, 2). The University of Colorado at Denver has used a version of this procedure as a laboratory in its second-semester course for nonmajors. Recently, students have been allowed to expand upon the procedures prescribed in the laboratory handout in an open-ended project format. We explored some of these variations in detail, and the results provided here offer ideas, centered around this laboratory, for open-ended projects that can be used in an inquiry-based approach.

The NASA Kepler mission has elements that serve a variety of audiences: formal education (elementary, secondary, and colleges), informal education (planetarium shows and museum exhibits), and public outreach (broadcast TV, radio, website, CD-ROM, and toolkit for amateur astronomers). The Kepler Cam program will provide minority colleges with CCD cameras and training systems for ground-based observations of exoplanet transits. Kepler Cam is closely tied with the Hands-On Universe (HOU) project that aims to have high school students actively involved in research projects such as asteroid discovery, supernova searches, cataclysmic variable observations, and studies of the moons of Jupiter, Saturn, Uranus and Neptune. Last fall (2003), HOU completed an NSF funded study in the relative effectiveness of online and face-to-face professional development courses. The evaluator for the project was TIMSS (Third International Math and Science Study). Findings, based on student performance, indicate that online teacher courses are as effective as face-to-face courses in teacher professional development. Details are in this paper.

Student Reciprocal Peer Teaching as a Method for Active Learning: An Experience in an Electrotechnical Laboratory  

NASA Astrophysics Data System (ADS)

Active learning is one of the most efficient mechanisms for learning, according to the psychology of learning. When students act as teachers for other students, the communication is more fluent and knowledge is transferred easier than in a traditional classroom. This teaching method is referred to in the literature as reciprocal peer teaching. In this study, the method is applied to laboratory sessions of a higher education institution course, and the students who act as teachers are referred to as "laboratory monitors." A particular way to select the monitors and its impact in the final marks is proposed. A total of 181 students participated in the experiment, experiences with laboratory monitors are discussed, and methods for motivating and training laboratory monitors and regular students are proposed. The types of laboratory sessions that can be led by classmates are discussed. This work is related to the changes in teaching methods in the Spanish higher education system, prompted by the Bologna Process for the construction of the European Higher Education Area

Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE) Code Reference Manual  

SciTech Connect

The Systems Analysis Programs for Hands-on Integrated Reliability Evaluations (SAPHIRE) is a software application developed for performing a complete probabilistic risk assessment (PRA) using a personal computer. SAPHIRE is funded by the U.S. Nuclear Regulatory Commission (NRC) and developed by the Idaho National Laboratory (INL). The INL's primary role in this project is that of software developer. However, the INL also plays an important role in technology transfer by interfacing and supporting SAPHIRE users comprised of a wide range of PRA practitioners from the NRC, national laboratories, the private sector, and foreign countries. SAPHIRE can be used to model a complex system’s response to initiating events, quantify associated damage outcome frequencies, and identify important contributors to this damage (Level 1 PRA) and to analyze containment performance during a severe accident and quantify radioactive releases (Level 2 PRA). It can be used for a PRA evaluating a variety of operating conditions, for example, for a nuclear reactor at full power, low power, or at shutdown conditions. Furthermore, SAPHIRE can be used to analyze both internal and external initiating events and has special features for transforming models built for internal event analysis to models for external event analysis. It can also be used in a limited manner to quantify risk in terms of release consequences to both the public and the environment (Level 3 PRA). SAPHIRE includes a separate module called the Graphical Evaluation Module (GEM). GEM provides a highly specialized user interface with SAPHIRE that automates SAPHIRE process steps for evaluating operational events at commercial nuclear power plants. Using GEM, an analyst can estimate the risk associated with operational events in a very efficient and expeditious manner. This reference guide will introduce the SAPHIRE Version 7.0 software. A brief discussion of the purpose and history of the software is included along with general information such as installation instructions, starting and stopping the program, and some pointers on how to get around inside the program. Next, database concepts and structure are discussed. Following that discussion are nine sections, one for each of the menu options on the SAPHIRE main menu, wherein the purpose and general capabilities for each option are furnished. Next, the capabilities and limitations of the software are provided.

Behavioral and Activity Assessment of Laboratory Mice (Mus musculus) after Tail Biopsy under Isoflurane Anesthesia  

PubMed Central

Contemporary laboratory animal guidance suggests that tail biopsy of laboratory mice can be performed before 21 d of age without anesthesia, whereas older mice must receive anesthesia before biopsy. Our objective was to determine whether administration of isoflurane anesthesia before tail biopsy produced a measurable effect on the behavior of mice (n = 196). We evaluated C57BL/6 and BALB/c mice at 21 to 24 (weaning), 28 to 31 (delayed weaning), and 42 to 45 (adult) d of age. Mice were observed at the time of biopsy and then twice within the first hour after a sham or tail biopsy. Anxiety-like responses were assessed by using an elevated plus-maze. Activity was evaluated remotely for 120 min. Isoflurane did not diminish acute responses to tail biopsy in mice 31 d or younger compared with sham-biopsied animals but had a significant effect in C57BL/6 biopsied adult mice. In addition, mice of all ages and strains that received anesthesia, regardless of biopsy, spent more time in the enclosed maze arms and had decreased activity up to 5 h after isoflurane exposure. Although tail biopsy should be performed in young mice to avoid transection of distal mature vertebrae, our experimental paradigm indicates that isoflurane anesthesia does not appreciably enhance wellbeing over that of mice biopsied without anesthesia at weaning ages. The influence of inhaled isoflurane was demonstrable and indicated that acute and prolonged alterations in anxiety and activity must be considered when interpreting the impact of anesthesia on tail biopsy across various ages and strains of laboratory mice.

Safeguards Implementation: Establishment of Indonesian Safeguards Laboratory  

SciTech Connect

Under the International Nuclear Safeguards and Engagement Program (INSEP), U.S. National Laboratories support the Department of Energy (DOE) National Nuclear Security Administration (NNSA) to ''collaborate with international partners to strengthen international safeguards at all stages of nuclear development.'' This engagement in safeguards implementation cooperation is the basis for the security and safeguards arrangement with the Nuclear Energy Regulatory Agency of the Republic of Indonesia (BAPETEN) and includes strengthening of the State System of Accounting for and Control of Nuclear Material (SSAC). There are many components in a robust SSAC. While INSEP carries on its program in a holistic approach, it is more effective and efficient to address individual components, rather than the entire system at one time, with the objective of strengthening the system as a whole. Nuclear material accountancy is one of these components. Nuclear material accountancy necessitates that a State periodically take an inventory of its material and record changes. To better perform these activities, BAPETEN requested assistance with establishing a safeguards laboratory where its staff could perform independent material characterization, maintain nondestructive assay equipment, and facilitate hands-on training of BAPETEN safeguards inspectors. In compliance with International Atomic Energy Agency (IAEA) guidelines and safety series documents, INSEP and BAPETEN opened the BAPETEN Safeguards Laboratory in February 2010 to provide these competencies. BAPETEN showcased these new capabilities in July 2010 at the IAEA-sponsored Regional Workshop on Nuclear Material Accounting and Control at Facilities where hands-on activities were held at BAPETEN's Headquarters in Jakarta using the equipment supplied by INSEP. Discussions have begun on the establishment of a security and safeguards laboratory at the BAPETEN Training Center located in Cisarua. This paper describes the many steps involved with the Safeguards Laboratory Implementation Plan from its drafting in August 2007 to the completion of the laboratory in February 2010.

Hands on what? The relative effectiveness of physical versus virtual materials in an engineering design project by middle school children  

NASA Astrophysics Data System (ADS)

Hands-on activities play an important, but controversial, role in early science education. In this study we attempt to clarify some of the issues surrounding the controversy by calling attention to distinctions between: (a) type of instruction (direct or discovery); (b) type of knowledge to be acquired (domain-general or domain-specific); and (c) type of materials that are used (physical or virtual). We then describe an empirical study that investigates the relative effectiveness of the physical-virtual dimension. In the present study, seventh and eighth grade students assembled and tested mousetrap cars with the goal of designing a car that would go the farthest. Children were assigned to four different conditions, depending on whether they manipulated physical or virtual materials, and whether they had a fixed number of cars they could construct or a fixed amount of time in which to construct them. All four conditions were equally effective in producing significant gains in learners' knowledge about causal factors, in their ability to design optimal cars, and in their confidence in their knowledge. Girls' performance, knowledge, and effort were equal to boys' in all conditions, but girls' confidence remained below boys' throughout. Given the fact that, on several different measures, children were able to learn as well with virtual as with physical materials, the inherent pragmatic advantages of virtual materials in science may make them the preferred instructional medium in many hands-on contexts.

The influence of age and gender on antioxidant enzyme activities in humans and laboratory animals.  

PubMed

Antioxidative/oxidative balance is one of the important factors for homeostasis. Antioxidative systems which protect from peroxidative damage are supposed to be under the influence of steroid hormones. The implications of this influence are age and gender as well as tissue dependent alterations in antioxidative enzyme activities. Apart from hormonal influence, antioxidative enzymes require the presence of microelements in their active centers as well as concerted action of non enzymatic antioxidants which support enzymes in their scavenging action. The aim of this review is to analyze and compare existing knowledge about the changes in activity of antioxidant enzymes in human and animal females and males of different age. Evidence as regards participation of oxidative stress in senescence are specific diseases which, to some extent, are gender dependent and appear more frequently in males or females. Several experiments in laboratory animals revealed that changes in enzyme activities are reflected in histopathological pictures of cells. The alterations observed during perimenopausal period provide with additional evidence of the participation of steroid hormones in the regulation of antioxidative system activity. Moreover, estrogens themselves exhibit antioxidative activity which is receptor independent. In conclusion, apart from genetic-related influences, also diet and style of life may have an impact on the antioxidative system which requires appropriate supplementation in microelements and vitamins for its effective function of scavenging excess of free radicals.

Activity rhythms and masking response in the diurnal fat sand rat under laboratory conditions.  

PubMed

Daily rhythms are heavily influenced by light in two major ways. One is through photic entrainment of a circadian clock, and the other is through a more direct process, referred to as masking. Whereas entraining effects of photic stimuli are quite similar in nocturnal and diurnal species, masking is very different. Laboratory conditions differ greatly from what is experienced by individuals in their natural habitat, and several studies have shown that activity patterns can greatly differ between laboratory environment and natural condition. This is especially prevalent in diurnal rodents. We studied the daily rhythms and masking response in the fat sand rat (Psammomys obesus), a diurnal desert rodent, and activity rhythms of Tristram's jird (Meriones tristrami), a nocturnal member of the same subfamily (Gerbillinae). We found that most sand rats kept on a 12?h:12?h light-dark (LD) cycles at two light intensities (500 and 1000?lux) have a nocturnal phase preferences of general activity and higher body temperature during the dark phase. In most individuals, activity was not as stable that of the nocturnal Tritram's jirds, which showed a clear and stable nocturnal activity pattern under the same conditions. Sand rats responded to a 6-h phase advance and 6-h phase delay as expected, and, under constant conditions, all tested animals free ran. In contrast with the nocturnal phase preference, fat sand rats did not show a masking response to light pulses during the dark phase or to a dark pulse during the light phase. They did, however, have a significant preference to the light phase under a 3.5?h:3.5?h LD schedule. Currently, we could not identify the underlying mechanisms responsible for the temporal niche switch in this species. However, our results provide us with a valuable tool for further studies of the circadian system of diurnal species, and will hopefully lead us to understanding diurnality, its mechanisms, causes, and consequences.

Almahata Sitta meteorite: gamma -activity measurements at Monte dei Cappuccini Laboratory in Torino  

NASA Astrophysics Data System (ADS)

The asteroid 2008TC3 was telescopically seen prior to entering Earth's atmosphere and was predicted to fall in Sudan on October 7, 2008, as it actually happened. Subsequently, many fragments were collected from the Nubian desert. At Monte dei Cappuccini Laboratory (IFSI, INAF) in Torino, using a selective gamma spectrometer we measured gamma rays from fragment #15, one of the largest retrieved, a ureilite of mass 75 g. Six cosmogenic radionuclides have been measured (46textrm {Sc}, 57textrm {Co}, 54textrm {Mn}, 22textrm {Na}, 60textrm {Co} and 26textrm {Al}). 60Co and 26Al activities allowed us to deduce that the fragment was located at a depth of 41±14 cm inside the 1.5-2 m radius asteroid. Moreover, 22Na activity is slightly greater than expected on the basis of the average cosmic ray flux and this could be ascribed to the prolonged solar minimum preceding the meteorite fall.

Field and Laboratory Investigations of Enhanced Biological Activity Influencing Groundwater Velocity and Electromagnetic Wave Propagation  

NASA Astrophysics Data System (ADS)

Field observations of groundwater velocity using point velocity probes (PVPs) and aquifer dielectric properties using ground penetrating radar (GPR) were made in a bioremediating, gasoline contaminated aquifer to which dissolved oxygen was introduced using Oxygen Release Compound (ORC®). PVPs are sensitive to changes in groundwater flow; whereas GPR is sensitive to changes in the dielectric and geoelectric properties of the pore- fluid and aquifer material. Therefore, the two methods provided complimentary and independent evidence for pore-scale changes associated with enhanced biological activity. Following the addition of ORC, PVP and GPR measured velocities nearest the ORC wells changed in a consistent manner throughout the experiment. GPR velocities measured further down-gradient, outside the influence of the ORC, did not indicate the same trend. Results from geochemical and flow modeling, combined with gas and biomass measurements, show that PVP and GPR velocity changes were not artifacts of seasonally fluctuating hydraulic gradient or temperature. Rather, the changes appear to be caused by factors related to elevated levels biological activity in the aquifer. Preliminary geophysical laboratory testing in a large sandbox reactor previously identified consistent trends with field GPR data that mirrored the field observations. A new, more detailed, laboratory experiment using GPR and PVPs was initiated to 1) confirm with confidence the phenomena observed in the field and the preliminary lab tank experiment, and 2) to gain additional understanding of the mechanisms responsible for PVP and GPR responses. At the time of writing, the results of the detailed experiment are pending.

Effects of activity and energy budget balancing algorithm on laboratory performance of a fish bioenergetics model  

USGS Publications Warehouse

We evaluated the performance of the Wisconsin bioenergetics model for lake trout Salvelinus namaycush that were fed ad libitum in laboratory tanks under regimes of low activity and high activity. In addition, we compared model performance under two different model algorithms: (1) balancing the lake trout energy budget on day t based on lake trout energy density on day t and (2) balancing the lake trout energy budget on day t based on lake trout energy density on day t + 1. Results indicated that the model significantly underestimated consumption for both inactive and active lake trout when algorithm 1 was used and that the degree of underestimation was similar for the two activity levels. In contrast, model performance substantially improved when using algorithm 2, as no detectable bias was found in model predictions of consumption for inactive fish and only a slight degree of overestimation was detected for active fish. The energy budget was accurately balanced by using algorithm 2 but not by using algorithm 1. Based on the results of this study, we recommend the use of algorithm 2 to estimate food consumption by fish in the field. Our study results highlight the importance of accurately accounting for changes in fish energy density when balancing the energy budget; furthermore, these results have implications for the science of evaluating fish bioenergetics model performance and for more accurate estimation of food consumption by fish in the field when fish energy density undergoes relatively rapid changes.

Comparison of blood pressure and sympathetic activity of rabbits in their home cage and the laboratory environment.  

PubMed

Methodological improvements in measuring cardiovascular parameters have meant that data can be collected from freely moving animals in their home cage. However, experiments in rabbits still often require them to be restrained in a laboratory setting. The aim of this study was to determine whether measurements collected when rabbits were placed in a holding box in the laboratory are representative of values obtained in freely moving conscious rabbits. Nine New Zealand White rabbits received two radiotelemetry implants to monitor mean arterial pressure (MAP) and renal sympathetic nerve activity (RSNA). The MAP measured in the laboratory (71 ± 1 mmHg) was similar to that in the home cage (69 ± 1 mmHg), but there was less MAP variability. The RSNA was also similar in both environments. In contrast, laboratory heart rate (HR) was 7% lower than home cage HR (181 ± 4 beats min(-1), P < 0.001), but HR variability was similar. Baroreflex gain, assessed by spectral analysis, was 19% higher in the laboratory than in the home cage due to lower MAP mid-frequency variability in the laboratory. Home cage circadian patterns of MAP and HR were strongly influenced by feeding and activity. Nevertheless, MAP and RSNA laboratory measurements were the same as average 24 h values and remained similar over several weeks. We conclude that while HR is generally lower in the laboratory, a valid representation of MAP and RSNA can be given by laboratory measurements. PMID:22613739

Early Earth Science Activities in the Sanford Underground Science and Engineering Laboratory at Homestake  

NASA Astrophysics Data System (ADS)

On July 10, 2007, the former Homestake Mine, Lead, South Dakota, was selected as the development site for the Deep Underground Science and Engineering Laboratory, to become the Sanford Underground Science and Engineering Laboratory at Homestake. Work on refurbishment and certification of the Ross Shaft began in August 2007 to effect pumping of water that had reached the 5000 level in late July. Completion of this work will allow a physics and geosciences laboratory to be constructed on the 4,850 ft level (1,478 m from the surface). Concurrent with reentry operations, several earth science research activities have been initiated. These early activities are as follows: (1) Seismic monitoring system: Accelerometers will be installed in surface boreholes and underground drifts as they become available as a result of the reentry work. (2) Evaluation of the 300 level (91 m), which has multiple locations for horizontal access, is ongoing. This near- surface level, with varying overburden thicknesses, offers excellent opportunities to investigate the "critical zone" in terms of hydrology, ecology, and geochemistry, yielding measurements of both moisture and carbon fluxes to evaluate fluid exchanges with the atmosphere. (3) Water and soil samples were collected in the Ross Shaft as part of the first reentry work. Molecular survey of microbial diversity showed the presence of mesophilic and thermophilic cellulose-degrading microorganisms. (4) Supercritical carbon dioxide injection experiments are being planned that will take advantage of three pairs of existing, nearly vertical, open 8-inch (0.2 m) boreholes that are easily accessible from the Ross Shaft. The candidate holes are located between the 1550 and the 2900 levels and are between 90 to 180 m in length (5) Monitoring of the response of the water during the dewatering operations will be facilitated by the use of existing boreholes. Ultimately, the dewatering operation provide access to the 8000 level (depth of 2,438 m), the deepest level. These five examples of ongoing research activities should provide a basis for many other earth science and engineering investigations at this multilevel facility, which already has extensive underground workings. These examples address different aspects of three main themes identified as important by deep underground research communities: restless earth for geo-science, ground truth for geo-engineering, and dark life for geo-microbiology.

The organization and running of postgraduate endodontic 'hands-on' courses.  

PubMed

Considerable preparation, planning and detailed organization are necessary if endodontic 'hands-on' courses are to be stimulating and worthwhile for participant and teacher alike. Projection facilities, lighting, seating and working surface requirements must be checked immediately on arrival at the venue. The format, although flexible enough to allow for the wide range of knowledge and practical ability found within any one group, must adhere to and stress the current fundamentals in endodontic teaching. Not only can information and skill in diagnosis, root canal preparation and obturation be taught in a 'hands-on' format, but rubber dam isolation techniques can also be practised very successfully. Tutors must be prepared to demonstrate personally their clinical ability and experience of principles and techniques taught during the course. Post-course feedback can be an extremely useful means of ensuring that 'hands-on' courses are relevant, with the appropriate practical emphasis required by the general dental practitioner, as well as the necessary stress on endodontic principles.

Hands-on distance learning is an effective way to boost physics understanding and skills of inservice teachers  

NASA Astrophysics Data System (ADS)

Since 1993 the University of Kentucky has been developing methodologies and resources for boosting in-service teachers' process skills and conceptual understanding of physics through various forms of inquiry based learning. With funding from FIPSE we have developed a set of distance learning courses (``Light'', ``Temperature, Heat, & Energy'', ``Electricity & Magnetism'', ``Force, Motion, & Energy'') to teach physics concepts to rural teachers in grades 4-9. These courses consist of hands-on activities that the teachers can use in their own classrooms, and are based on a materials kit sent to each participant, allowing guided inquiry be the instructional approach. The courses are asynchronous and may be taken by individuals or small groups, for professional development or course credit, and are now being offered to teachers nationwide (see http://www.hovphysics.com). With NSF support we are now studying how much of what a teacher learns in a course transfers to the teacher's students.

Soil Activation and Groundwater Contamination at Brookhaven National Laboratory, Upton, New York  

SciTech Connect

In November 1999, tritium (H-3) was detected in the groundwater near one of Brookhaven National Laboratory's (BNL) accelerator experiments at concentrations above the 20,000 pico curie per liter (pCi/L) Maximum Contaminant Level (MCL). Sodium-22 (Na-22) was also detected in the groundwater, but at concentrations well below the 400 pCi/L MCL. An investigation into the source of the contamination revealed that the tritium and sodium-22 originated from activated soil shielding located adjacent to the g-2 target building where approximately five percent of the beam was inadvertently striking one of the beam-line magnets. Rainwater was able to infiltrate the activated soils and carry the tritium and sodium-22 into the groundwater. The highest tritium level detected in groundwater during the 1999 investigation was nearly 1.8 million pCi/L. To prevent additional rainwater infiltration into the activated soil shielding, a concrete cap was constructed over the soil shielding in December 1999. Other corrective actions included refocusing the beam and improved beam loss monitoring to reduce additional soil activation, storm-water management improvements, and additional groundwater monitoring. From 2001 through 2004, three high concentration zones (or slugs) of tritium were observed passing through the groundwater monitoring well network immediately down-gradient of the source area, with a maximum observed concentration of 3.4 million pCi/L. Some of the tritium that was previously leached from the activated soil was trapped in the vadose (unsaturated) zone soils directly above the water table after then cap was installed. A portion of this residual tritium was later mobilized into the groundwater during periods of high groundwater table elevations, which can occur following heavy seasonal rainfall. Monitoring results for the past two years indicate that the amount of tritium being released from the vadose zone is decreasing, with tritium concentrations consistently below 100,000 pCi/L. The tritium plume is currently 550 meters long, and is located entirely in the central portion of the BNL site. The plume has not impacted any of the Laboratory's drinking water supply wells. Contaminant transport modeling suggests that the tritium plume will attenuate entirely in the central portion of the BNL site by years 2010-2015. (authors)

On the effectiveness of active-engagement microcomputer-based laboratories  

NASA Astrophysics Data System (ADS)

One hour active-engagement tutorials using microcomputer-based laboratory (MBL) equipment were substituted for traditional problem-solving recitations in introductory calculus-based mechanics classes for engineering students at the University of Maryland. The results of two specific tutorials, one on the concept of instantaneous velocity and one on Newton's third law were probed by using standard multiple-choice questions and a free-response final exam question. A comparison of the results of 11 lecture classes taught by six different teachers with and without tutorials shows that the MBL tutorials resulted in a significant improvement compared to the traditional recitations when measured by carefully designed multiple-choice problems. The free-response question showed that, although the tutorial students did somewhat better in recognizing and applying the concepts, there is still room for improvement.

Electrochemical activity and bacterial diversity of natural marine biofilm in laboratory closed-systems.  

PubMed

Even if a widely shared mechanism actually does not exist, it is now generally accepted that, in aerobic conditions, marine electrochemically active biofilms (MEABs) induce faster oxygen reduction on stainless steel immersed in seawater. This phenomenon has been widely studied, but nearly all the experiments found in literature have been conducted in open-systems (i.e. experimental environments where seawater is constantly renewed). In this work we tried to obtain, in open circuit and potentiostatic conditions, MEABs in different laboratory closed-systems without water renewal (mesocosms), in order to verify the relationship between electrochemical activity and biofilm composition. The diversity of the microbial populations of biofilms obtained by our new kind of approach was examined by the DGGE technique (denaturing gradient gel electrophoresis). MEABs were obtained in all the mesocosms from 2000 to 2 L, showing in some cases electrochemical performances comparable to those of open-systems, and a very high genetic variability. Our DGGE results underline the difficulty in finding a correlation between electrochemical activity and composition of microbial populations. PMID:19481980

A Comprehensive Approach to Partnering Scientists with Education and Outreach Activities at a National Laboratory  

NASA Astrophysics Data System (ADS)

With the establishment of an Office of Education and Outreach (EO) in 2000 and the adoption of a five-year EO strategic plan in 2001, the University Corporation for Atmospheric Research (UCAR) committed to augment the involvement of AGU scientists and their partners in education and public outreach activities that represent the full spectrum of research in the atmospheric and related sciences. In 2002, a comprehensive program is underway which invites scientists from UCAR, the National Center for Atmospheric Research (NCAR), and UCAR Office of Programs (UOP) into partnership with EO through volunteer orientation workshops, program specific training, skill-building in pedagogy, access to classroom resources, and program and instructor evaluation. Scientists contribute in one or several of the following roles: program partners who bridge research to education through collaborative grant proposals; science content advisors for publications, web sites, exhibits, and informal science events; science mentors for high school and undergraduate students; NCAR Mesa Laboratory tour guides; scientists in the schools; science education ambassadors to local and national community events; science speakers for EO programs, conferences, and meetings of local organization; and science wizards offering demonstrations at public events for children and families. This new EO initiative seeks to match the expertise and specific interests of scientists with appropriate activities, while also serving as a communications conduit through which ideas for new activities and resources can be seeded and eventually developed into viable, fully funded programs.

Recent upgrade of the in vivo neutron activation facility at Brookhaven National Laboratory  

SciTech Connect

The in vivo neutron activation facility at Brookhaven National Laboratory consists of a delayed- and a prompt-gamma neutron activation (DGNA and PGNA) system and an inelastic neutron scattering (INS) system. The total body contents of several basic elements, including potassium, calcium, chlorine, sodium, and phosphorus are measured at the DGNA system; total body carbon is measured at the INS system; and the nitrogen-tohydrogen ratio is measured at the PGNA system. Based on the elemental composition, body compartments, such as total body fat and total body protein can be computed with additional independently measured parameters, such as total body water, body size, and body weight. Information on elemental and compartmental body composition obtained through neutron activation analysis is useful, if not essential, for research on growth, malnutrition, aging diseases, such as osteoporosis and acquired immunodeficiency syndrome in which the progression of the illness is closely related to changes in major body compartments, such as bone, adipose tissue, and muscle. The DGNA system has been modified and upgraded several times since it was first built. Recently, all three systems underwent major upgrades. This upgrading and some preliminary studies carried out with the modified facilities are reported here.

Lawrence Livermore National Laboratory?s Book of Minimum Detectable Activity for Direct Measurement of Internally Deposited Radionuclides in Radiation Workers  

SciTech Connect

Lawrence Livermore National Laboratory maintains an in vivo measurement program designed to identify and evaluate the activity of radionuclides deposited in the body. Two types of systems are primarily used for the routine monitoring of radiation workers, the lung counting system and the scanning bed whole body counting system. The lung counting system is comprised of two Canberra ACTII detector sets. Each ACTII set contains two planar germanium detectors with carbon composite end windows optimized to measure low energy photon emitting radionuclides. The ACTII detectors are placed on the upper torso over the lungs for the direct measurement of internally deposited radionuclides in the lungs that emit low energy photons. A correction for the thickness of the chest wall is applied to the efficiency. Because the thickness of the chest wall is a key factor in the measurement of low energy photon emitting radionuclides in the lung, the minimum detectable activity is a function of the chest wall thickness. The scanning bed whole body counting system is comprised of a thin air mattress on top of a carbon fiber bed that slowly scans over four high purity germanium detectors. The scanning system is designed to minimize variations in detected activity due to radionuclide distribution in the body. The scanning bed detection system is typically used for the measurement of internally deposited radionuclides that emit photons above 100 to 200 keV. MDAs have been generated for radionuclides that provide energies above 80 keV since the lowest calibration energy for the system is approximately 86 keV. The following charts and table provide best determination of minimum detectable activity using human subjects as controls for the background contributions. A wide variety of radionuclides are used throughout the laboratory and the following pages represent several of the radionuclides that have been encountered at the Whole Body and Spectroscopy Laboratories within Hazards Control.

Survival and catabolic activity of natural and genetically engineered bacteria in a laboratory-scale activated-sludge unit.  

PubMed

The survival of selected naturally occurring and genetically engineered bacteria in a fully functional laboratory-scale activated-sludge unit (ASU) was investigated. The effect of the presence of 3-chlorobenzoate (3CB) on the survival of Pseudomonas putida UWC1, with or without a chimeric plasmid, pD10, which encodes 3CB catabolism, was determined. P. putida UWC1(pD10) did not enhance 3CB breakdown in the ASU, even following inoculation at a high concentration (3 x 10(8) CFU/ml). The emergence of a natural, 3CB-degrading population appeared to have a detrimental effect on the survival of strain UWC1 in the ASU. The fate of two 3CB-utilizing bacteria, derived from activated-sludge microflora, was studied in experiments in which these strains were inoculated into the ASU. Both strains, AS2, an unmanipulated natural isolate which flocculated readily in liquid media, and P. putida ASR2.8, a transconjugant containing the recombinant plasmid pD10, survived for long periods in the ASU and enhanced 3CB breakdown at 15 degrees C. The results reported in this paper illustrate the importance of choosing strains which are well adapted to environmental conditions if the use of microbial inoculants for the breakdown of target pollutants is to be successful.

Lessons Learned from V-Tank Waste Remediation Activities at the Idaho National Laboratory  

SciTech Connect

The purpose of this paper is to discuss major activities and lessons learned from remediation of the V-tank waste at Idaho National Laboratory's (INL's) Test Area North (TAN) complex. Remediation activities involved the on-site treatment, solidification and disposal of over 61,000 L (16,000 gal) of radioactively hazardous V-tank waste. In July, 2006, over 98% of the V-tank waste was disposed of at the Idaho CERCLA Disposal Facility (ICDF). Disposal was accomplished using the three 38,000-L (10,000-gal) V-tanks that had stored most of the V-tank waste for over 30 years. Included in V-Tank remediation was the removal of approximately 7,650 m{sup 3} (10,000 yd{sup 3}) of contaminated soil. Plans are to treat the remaining V-tank waste off-site in early 2007, with the treated residual also disposed of at the ICDF. Disposal of the treated V-tank waste at ICDF marked a major step in completing remediation of the TAN V-tanks, a task begun in 1999 when the original Record of Decision (ROD) was published. Over this time, there have been a number of stops and starts associated with remediating this waste. Although many of these stops and starts were unavoidable, there are a number of lessons learned for the V-tank remediation that could help prevent unnecessary expenses and schedule delays in future remediation activities within the Department of Energy (DOE) complex. This paper identifies major and minor lessons learned from V-tank waste remediation efforts - those that resulted in unnecessary delays/expenses, as well as those areas that accelerated V-tank remediation efforts.

Hands-On Universe: A Global Program for Education and Public Outreach in Astronomy  

NASA Astrophysics Data System (ADS)

Hands-On Universe (HOU) is an educational program that enables students to investigate the Universe while applying tools and concepts from science, math, and technology. Using the Internet, HOU participants around the world request observations from an automated telescope, download images from a large image archive, and analyze them with the aid of user-friendly image processing software. This program is now in many countries, including the USA, France, Germany, Sweden, Japan, and Australia. A network of telescopes has been established, many of them remotely operated. Students in the classroom are able to make night observations during the day, using a telescope in another country. An archive of images taken on large telescopes is also accessible, as well as resources for teachers. Students deal with real research projects, e.g., the search for asteroids, which resulted in the discovery of a Kuiper Belt object by high-school students. Not only does Hands-On Universe give the general public access to professional astronomy, it also demonstrates the use of a complex automated system, data processing techniques, and automation. Using telescopes located in many countries over the globe, a powerful and genuine cooperation between teachers and children from various countries is promoted, with a clear educational goal.

An Online Hands-On Program for Middle-School Science Teachers  

NASA Astrophysics Data System (ADS)

Science Education Online (SEO) is a new program of science and pedagogy courses developed at the University of Massachusetts, Amherst and Lowell campuses, and now offers a Masters Degree in Science Education. The program was developed with NSF support over the last three years and has the goal of reaching in-service teachers, particularly in urban and rural communities. The science content courses have been developed by science and education faculty at UMass, working in collaboration to address Massachusetts and national science frameworks at the middle-school level. The SEO courses take a hands-on approach, with kits of inexpensive materials, cooperative learning strategies, and sharing of digital pictures. We give detailed examples of implementing the online hands-on approach from an astronomy course we developed using many Project STAR materials. One of the more interesting results of the online format is that teachers report that they have found themselves mastering skills that they had avoided in lab group work in college courses. By its nature, the online format also requires the teachers to express their understanding in writing, and we have found that small online groups are effective in helping the teachers to clarify their understanding. The SEO program was developed under National Science Foundation Grant # ESI-0243536.

NASA Astrophysics Data System (ADS)

Daily foraging activity of Anacanthotermes vagans was tested using toilet paper rolls as bait. The highest activity was recorded at midnight and during the hours of the early morning in both summer and winter seasons. In spring the time of highest activity was reversed to take place at midday, afternoon and early evening. Aktograph records in the laboratory demonstrated that individual workers are active most of the day and not naturally entrianed by photoperiods. Daily activity of groups of 10 workers was not statistically different from that of individual workers.

An assessment of Hyalella azteca burrowing activity under laboratory sediment toxicity testing conditions.  

PubMed

Burrowing of the freshwater amphipod Hyalella azteca was evaluated under laboratory conditions similar to those recommended for standard sediment toxicity testing in Canada (EPS 1/RM/33; Environment Canada, 1997) and the United States (EPA/600/R-99/064; US EPA, 2000). Sediment type, time of day (light versus dark), size of animal, and the presence or absence of food were varied to assess their effects on burrowing activity. Hyalella azteca were found to burrow rapidly in fine, organic-rich sediments, but were slower to burrow in a sandy sediment. There was no increase in the number of animals occupying the sediment surface of a fine, organic-rich sediment after 4h of darkness compared to the previous 4h of light. Over a 9- to 10-d duration, a higher percentage of animals occupied the surface of the sandy sediment. The addition of food promoted burrowing in sandy sediment, as did using smaller animals. Overall, longer-duration tests involving older animals and coarse sediments may require formal observation to confirm burrowing and ensure adequate sediment exposure. The addition of food during a test may promote the burrowing of larger animals in coarse sediments, but may not be necessary in field-collected sediments that are not excessively sandy.

An Overview of Science Education and Outreach Activities at the Princeton Plasma Physics Laboratory  

SciTech Connect

The U. S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has an energetic science education program and outreach effort. This overview describes the components of the programs and evaluates the changes that have occurred in this effort during the last several years. Efforts have been expanded to reach more students, as well as the public in general. The primary goal is to inform the public regarding the fusion and plasma research at PPPL and to excite students so that they can appreciate science and technology. A student's interest in science can be raised by tours, summer research experiences, in-classroom presentations, plasma expos, teacher workshops and web-based materials. The ultimate result of this effort is a better-informed public, as well as an increase in the number of women and minorities who choose science as a vocation. Measuring the results is difficult, but current metrics are reviewed. The science education and outreach programs are supported by a de dicated core group of individuals and supplemented by other members of the PPPL staff and consultants who perform various outreach and educational activities.

The erosion behaviour of biologically active sewer sediment deposits: observations from a laboratory study.  

PubMed

The erosion behaviour of various fine-grained sediment deposits has been investigated in laboratory experiments. This work mainly focused on tests using sewer sediment in which strong biochemical reactions were observed during the deposit formation period. A small number of initial tests were conducted in which the deposits were made from mixtures of "clean" mineral and organic sediments. The erosion behaviour observed in these tests was compared with the erosion characteristics for sediments taken from deposits in a sewer. The impact of the biological processes on physical properties such as bulk density, water content, deposit structure and the erosive behaviour as a function of bed shear stress are quantified and discussed. Based on these observations it is believed that bio-processes weaken the strength of the in-pipe sediment deposits. A significantly weaker sediment surface layer was observed during deposition under quiescent oxygen-rich conditions. This resulted in a deposit with low shear strength which may be a cause of a first foul flush of suspended sediment when flow rates were increased. Comparison between tests with sewer sediments and the artificial representative surrogates suggested that the deposits of the later did not correctly simulate the depositional development and the resultant erosion patterns observed with the more bio-active sewer sediment.

Preliminary siting activities for new waste handling facilities at the Idaho National Engineering Laboratory  

SciTech Connect

The Idaho Waste Processing Facility, the Mixed and Low-Level Waste Treatment Facility, and the Mixed and Low-Level Waste Disposal Facility are new waste treatment, storage, and disposal facilities that have been proposed at the Idaho National Engineering Laboratory (INEL). A prime consideration in planning for such facilities is the selection of a site. Since spring of 1992, waste management personnel at the INEL have been involved in activities directed to this end. These activities have resulted in the (a) identification of generic siting criteria, considered applicable to either treatment or disposal facilities for the purpose of preliminary site evaluations and comparisons, (b) selection of six candidate locations for siting,and (c) site-specific characterization of candidate sites relative to selected siting criteria. This report describes the information gathered in the above three categories for the six candidate sites. However, a single, preferred site has not yet been identified. Such a determination requires an overall, composite ranking of the candidate sites, which accounts for the fact that the sites under consideration have different advantages and disadvantages, that no single site is superior to all the others in all the siting criteria, and that the criteria should be assigned different weighing factors depending on whether a site is to host a treatment or a disposal facility. Stakeholder input should now be solicited to help guide the final selection. This input will include (a) siting issues not already identified in the siting, work to date, and (b) relative importances of the individual siting criteria. Final site selection will not be completed until stakeholder input (from the State of Idaho, regulatory agencies, the public, etc.) in the above areas has been obtained and a strategy has been developed to make a composite ranking of all candidate sites that accounts for all the siting criteria.

Hands-on curriculum teaches biomedical engineering concepts to home-schooled students.  

PubMed

University level outreach has increased over the last decade to stimulate K-12 student interest in engineering related fields. Home schooling students are one of the groups that are valued for engineering admissions due to diligent study habits and high achievement scores. However, home schooled students have inadequate access to science, math, and engineering related resources, which precludes the development of interdisciplinary teaching methods. To address this problem, we have developed a hands-on, STEM based curriculum as a safe and comprehensive supplement to current home schooling curricula. The ultimate goal is to stimulate university-student relations and subsequently increase engineering recruitment opportunities. Our pre and post workshop survey comparisons demonstrate that integrating disciplines, via the manner presented in this study, provides a K-12 student-friendly engineering learning method.

Physical science teachers with hands-on experience are critical to secondary education learning. In "Before It’s Too Late," the U.S. Department of Education (2000) estimated "about 56% of high school students taking physical science are taught by out-of-field teachers." In Tennessee, the problem is even greater, while the demand is increasing. This project aims to address the shortage of well-prepared physics and astronomy teachers. Austin Peay State University has recently installed a 0.5m telescope with imaging and rudimentary spectroscopic capability. We are committed to working with the College of Education to bring secondary teachers in training and practicing secondary teachers to the telescope to experience basic operations and conduct small research projects. This is done via classes and summer workshops. We describe the program setup, expectations for the participants, learning outcomes, and the evaluation process.

Science-based material modeling activities at Sandia National Laboratories/California : an overview.  

SciTech Connect

The purpose of this presentation is to provide an overview of the science-based materials modeling activities at Sandia National Laboratories, California. The main mission driver for the work is the development of predictive modeling and simulation capabilities leveraging high performance computing software and hardware. Presentation will highlight research accomplishments in several specific topics of current interest. Sandia/California has been engaged in the development of high performance computing based predictive modeling and simulation capabilities in support of the Science-Based Stockpile Stewardship Program of the U. S. Department of Energy. Of particular interest is the development of constitutive models that can efficiently and accurately predict post-failure material response and load-redistribution in systems and components. Fracture and failure are inherently multi-scale and our philosophy is to include required physics in our models at all appropriate scales. We approach the problems from the continuum point of view and intend to provide continuum models that include dominant subscale mechanisms. Moreover, numerical algorithms are needed to allow implementation of physical models in high performance computing codes such that large-scale modeling and simulation can be conducted. Other drivers of our effort include the emerging application of micro- and nano-systems and the increasing interest in biotechnology. In this presentation, our research in fracture and failure modeling, atomic-continuum coupling code development, microstructure-material properties relationships exploration, and general continuum theories advancement will be presented. Where appropriate, examples will be given to demonstrate the utility of the models.

Thermal Field Indicator for Identifying Active Faults and its Instability From Laboratory Experiments  

NASA Astrophysics Data System (ADS)

The relationship between the thermal filed and strain field during deformation of faults is the physical basis to clarify whether satellite infrared information and the ground temperature field can be used to study fault activity. This study attempts to discuss these problems by experiments in the laboratory. The two-direction servo-control system was used to load on the samples with compressional and extensional en echelon faults. An infrared thermal image system and a contact-type thermometer recorded synchronously variations of the bright temperature field of infrared radiation and temperature field during deformation of the rock specimens. A digital CCD camera and a soft ware based on the digital speckle correlation method (DSCM) was utilized to capture images and to analyze them, yielding processes of displacement and strain fields. The experimental result shows as follows: 1 The temperature is highest at the jog area of the compressional en echelon faults, whereas that is lowest at the extensional en echelon faults prior to failure of the jog area. The record by DSCM displays that the mean strain of the jog area is largest for the compressional en echelon faults, while that is smallest for the extensional en echelon faults. These mean that the temperature field has clear responses to the opposite stress states at the jog areas of two kinds of en echelon faults, providing an indicator for determining whether the fault segment has slid. 2 The en echelon faults experience two deformation stages from stress building up and fault propagating at the jog area to unstable sliding along the fault. Correspondingly the mechanism of heating-up is turned from strain heating into frictional heating. Three kinds of phenomena have been observed at the jog area and its vicinity during the stage of transformation. They are temperature drop, fast fluctuation of temperature, and pulses of temperature rising, respectively. Mechanism of these phenomena is discussed. 3 These variations of the thermal field at the jog area are followed by swift rise of temperature along the fault. The onset of temperature rise along fault occurs 2-3 seconds prior to its unstable slip. However, the temperature drop of the jog area happens about 20 seconds before the unstable slip of the fault and the appearance of temperature rising pulses is 10-20 seconds earlier than that of the unstable slip. They are precursors to unstable slip of the fault. These experimental analyses demonstrate that observations and studies on the thermal variations at the sensitive portion of a faults comparing with other relevant data are of great importance for detecting precursors ahead of unstable slip of active fault.

Several of these project are closely associated with major strategic thrusts of the Laboratory as described in Argonne`s Five Year Institutional Plan, although the scientific implications of the achieved results extend well beyond Laboratory plans and objectives. The projects supported by the Program are distributed across the major programmatic areas at Argonne. Areas of emphasis are (1) advanced accelerator and detector technology, (2) x-ray techniques in biological and physical sciences, (3) advanced reactor technology, (4) materials science, computational science, biological sciences and environmental sciences. Individual reports summarizing the purpose, approach, and results of projects are presented.

Hands-on approach during breastfeeding support in a neonatal intensive care unit: a qualitative study of Swedish mothers' experiences  

PubMed Central

Background Assisting mothers to breastfeed is not easy when babies experience difficulties. In a neonatal intensive care unit (NICU), nurses often help mothers by using hands-on-breast without their permission. Little is known about how mothers feel about this unusual body touching. To gain more knowledge from mothers who lived through this experience, this hands-on practice was studied in a NICU in Sweden. Methods Between January and June 2001, in-depth interviews were conducted with ten mothers of preterm or sick term infants and all of them experienced the hands-on approach. In this research, Radnitzky's seven principles of hermeneutic interpretation were applied in order to interpret the meaning of mothers' responses. This article presents results related to the period of initiation of breastfeeding. This qualitative study was based on a combination of the models of Gustafsson, Orem, and Aarts' Marte Meo. Results Five main themes were identified: Insult to integrity, Manipulating the baby, Understanding and adjustment, Breasts as objects, Alternatives to this practice. Hands-on help in the breastfeeding situation was experienced as unpleasant and the women experienced their breasts as objectified. The mothers accepted the hands-on help given by nursing staff, even though they considered it unpleasant. Most mothers expressed a need for assistance when starting breastfeeding, but could not suggest any alternative to hands-on help such as demonstrating with an artificial breast and a doll. Conclusion The study provides information about how mothers experience unexpected hands-on help with breastfeeding in a NICU, which has not been described previously. Since most mothers in this study regarded this behavior as unpleasant and not helpful mostly because it was unexpected and unexplained, it would be important to either explain beforehand to mothers what type of physical approach could be attempted on their body or better, to avoid this type of approach completely.

Hands-on at a Distance: Evaluation of a Temperature and Heat Distance Learning Course  

NASA Astrophysics Data System (ADS)

The No Child Left Behind Act requires that all teachers be certified within the content areas that they teach. However, attracting and retaining highly qualified science teachers in rural school districts is particularly difficult due to limited resources and geographic and professional isolation. Science professional development programs could help improve inservice teachers' understanding of concepts they are expected to teach, but such programs are often limited in rural areas. This study evaluates a unique distance learning, inquiry-based professional development course in physical science developed to meet the needs of central Appalachian middle school teachers. Instruction through hands-on inquiry investigations distinguishes this program from other distance learning programs. Preliminary findings from the pilot study reported in this paper reveal significant growth in 43 teachers' content knowledge for six of nine temperature and heat concepts assessed in the course. Outcomes from the distance learning project are discussed as they relate to future research goals and implications for science professional development programs in rural regions.

Modeling Lunar Phases in the Classroom: A Hands-On Interactive Lesson  

NASA Astrophysics Data System (ADS)

Using Power-Point technology and hands-on materials, a 45 minute lesson has been created to allow students to explore the cause of lunar phases. Students work in cooperative pairs to model the different phases of the moon. In addition, this lesson does not require a bright light source. Using a partially painted Styrofoam ball, a small cup of Play-dough, a simple, protractor, and a data collection sheet, students observe the lunar phases and measure the angle between the sun and the moon. Students place the moon model in eight different positions simulating its orbit around the earth and record the observed changes. The Power-Point presentation contains three segments. The first section allows the teacher to determine the students’ level of prior knowledge about the moon and to uncover possible misconceptions. The second section facilitates the students’ learning by displaying the proper alignment of the model and the proper viewing position for the students. Finally, the presentation culminates in a review of what the students have just observed. This lesson has been created to meet Georgia Performance Standards (GPS) for 4th grade science regarding the cause of lunar phases. Teacher and student responses to this lesson have been extremely positive.

The erosion behaviour of biologically active sewer sediment deposits: Observations from a laboratory study  

Microsoft Academic Search

The erosion behaviour of various fine-grained sediment deposits has been investigated in laboratory experiments. This work mainly focused on tests using sewer sediment in which strong biochemical reactions were observed during the deposit formation period. A small number of initial tests were conducted in which the deposits were made from mixtures of “clean” mineral and organic sediments. The erosion behaviour
