Sedimentary patterns and hydraulic effects can be studies in model streams which are not to scale. The "Western River" is such a model which is being used effectively at Western Carolina College. Construction of the model, student exercises, and observations made when using the model are discussed. (Author/JN)

Thirteen computer/calculator programs (available from authors) are described. These include: representation of molecules as 3-D models; animated 3-D graphical display of line drawings of molecules; principles of Fourier-transform nuclear magnetic resonance; tutorial program for pH calculation; balancing chemical reactions using a hand-held…

Discusses microbial production of methane from biomass. Topics include methogens (bacteria producing methane), ecology of methanogenesis, methanogenesis in ruminant/nonruminant and other environments, role of methanogenesis in nature, and methane production in sewage treatment plants. Also discusses construction of methane digesters (and related…

To test the literal biblical account of Noah's flood, four sources of possible flood waters were evaluated to determine if a natural (as opposed to supernatural) explanation is possible. Sources include rain, hydrothermal springs, and two types of cometary impact. Thermodynamic constraints preclude a natural means of accounting for the flood.…

Students (N=387) in grades 8, 10, 12, and college were administered eight reasoning items to test hypothesis that the basic logic utilized in individuals in scientific hypothesis testing is the biconditional and that the biconditional is a precondition for development of formal operations. Results and implications for science instruction are…

Discusses the construction of lenses made out of ice, including the arrangement for mounting an ice lens on a camera. Also discusses brewing coffee in an ibrik (long-handled container tapering slightly toward the top), focusing on the physics of the brewing. (JN)

Describes computer program (HUMAN) used to simulate physiological experiments on patient pathology. Program (available from authors, including versions for microcomputers) consists of dynamic interactions of over 150 physiological variables and integrating approximations of cardiovascular, renal, lung, temperature regulation, and some hormone…

Results of a National Science Foundation survey indicate that developing shortages of science and engineering graduates in the current labor force for the most part do not apply to chemists and chemical engineers. (Author/JN)

Traces the history of physiology at the University of Michigan, focusing on facilities, curriculum program and instruction, classic experiments, and faculty. Contributions of Henry Sewall and Warren Plimpton Lombard are discussed at some length. (JN)

Substantially self-paced programed learning at Sheffield City Polytechnic Metallurgy Department was found to be better than conventional lectures, provided that new topic areas covered were relatively small, as demonstrated by using inexpensive, simple instructional materials. (Author/JN)

Data on U.S. research and development (R&D) efforts are presented in chart and graph form, focusing on trends, sources of funds, performance and character of R&D, employed scientists/engineers, abstracts appearing in Chemical Abstracts, and U.S. patents. Indicates that most R&D is done by private industry with funding for development.…

Data are presented in chart and graph form focusing on research and development (R&D) funding by the federal government, including federal obligations for total R&D (largest increases for defense and space); research; scientific disciplines; development; basic research; applied research; university research and applied research; and funds…

Outlines a survey of laboratory practices and policies for employee protection from exposure to chemicals. Findings support the argument that academic, industrial, and other research laboratories are different from the manufacturing environment and should have a different toxic chemical policy and standards. (Author/SK)

Describes the status of the United Nation's fund for science and technology which started operation in May 1980; includes funds raised, current projects, and educational programs supported by the funds. (SK)

Surveys the attitudes toward teaching held by college biologists at one university. Reports that although keen interest in innovation is expressed, little is done about it. A major problem seems to be information flow, and simple ways of improving this are discussed. (Author/JN)
