Walker, Jearl – Scientific American, 1990
Describes the necking of polymer sheets that occurs when they are stretched. Discusses the effect and the mechanisms of necking. Lists four references. (YP)
Descriptors: Laboratory Experiments, Laboratory Procedures, Matter, Optics
Gay, William I. – Physiologist, 1984
Discusses the role of dogs in research, considering their use in studies related to: behavior; aging; anesthesia; gastrointestinal surgery; the brain; organ transplants; radiobiology; trauma and shock; arterial diseases; hemophelia; ophthalmology; diabetes; nutrition; cancer; lupus; cyclic neutropenia; thyroiditis; hepatitis; skeletal system,…

Moss, Thomas H. – Science, Technology, and Human Values, 1984
Discusses issues and the public's concerns related to using laboratory animals for research purposes. Indicates that several perceptions (such as recognizing that the public's attitudes toward respect for animal life are no more irrational than many broader attitudes toward the sacredness of life) characterize the most responsible of recent…
Descriptors: Animals, Federal Legislation, Higher Education, Laboratory Animals

Orchin, Milton – Journal of Chemical Education, 1989
The Grignard reagent used in the laboratory synthesis of organic compounds is the product resulting from the reaction of an alkyl or aryl halide with elemental magnesium. Describes the structure, formation, and some reactions of the reagent. (YP)
Descriptors: Chemical Analysis, Chemical Bonding, Chemical Reactions, Chemistry

Manalang, Mary G.; Bundy, Hallie F. – Journal of Chemical Education, 1989
Reports an experiment for examining protein-ligand binding using the enzyme carbonic anhydrase. Describes the experimental procedures consisting of the syntheses of an azosulfonamide and its complex formation with carbonic anhydrase. (YP)
Descriptors: Chemical Reactions, Chemistry, College Science, Enzymes

Johnson, Gordon; And Others – Journal of Science Teacher Education, 1991
Provides guidelines for translating university science laboratories into middle school science activities. The need for guidelines is based on the authors' discovery that teachers teach what they were taught. Discusses six expected outcomes of middle school science activities: developing science concepts; practicing process skills; quantitative…

Shimony, Abner – Scientific American, 1988
Describes experiments used during recent history to explain the nature of the quantum world. Explains the essential elements of experiments using polarized light and magnetic flux. Illustrates differences between classical theories in physics and quantum theory. Shows how experiments in the microscopic and macroscopic world appear to support…
Descriptors: Laboratory Experiments, Lasers, Magnets, Optics

Leonard, William H. – Journal of Research in Science Teaching, 1989
This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)
Descriptors: Biology, College Science, Inquiry, Laboratory Experiments

Zola, Judith C.; And Others – Science, Technology, and Human Values, 1984
Examines the extent to which issues related to animal experimentation are in conflict and proposes choices that might least comprise them. These issues include animal well-being, human well-being, self-interest of science, scientific validity and responsibility, progress in biomedical and behavioral science, and the future quality of medical care.…

Huebner, Jay S.; And Others – Journal of Chemical Education, 1988
Provides information appropriate for introductory lectures on photoelectric effects in membranes. Describes the apparatus and supplies required for laboratory exercises. Outlines typical laboratory exercises. Identifies the chromophores known to induce photoelectric effects. Concludes that this topic can provide useful subjects for undergraduate…
Descriptors: Biochemistry, College Science, Higher Education, Laboratory Experiments

Schallies, Michael; Redeker, Jorg – Journal of Chemical Education, 1988
Discusses general construction principles for miniaturized laboratory glassware. Describes a prototype experimental kit that allows the carrying out of all standard laboratory operations and discusses a trial use of the equipment with students 16- to 17-years-old. (CW)
Descriptors: Chemistry, College Science, Glass, Higher Education

Tobin, Kenneth – School Science and Mathematics, 1990
Reviews research on the purpose and effectiveness of laboratory activities. Discusses epistemology, problem solving, cooperative learning, student involvement, assessment, and teachers as researchers. (YP)
Descriptors: Elementary School Science, Elementary Secondary Education, Laboratory Experiments, Laboratory Procedures

Bretherick, Leslie – Journal of Chemical Education, 1989
Discussed are the potential hazards associated with nitric acid, inorganic and organic nitrate salts, alkyl nitrates, acyl nitrates, aliphatic nitro compounds, aromatic nitro compounds, and nitration reactions. (CW)
Descriptors: Acids, Chemical Reactions, Chemistry, College Science
McCollum, Terry L. – 1988
A conflict exists over the use of animals in the classroom. One aspect of this use involved the dissection of animals. Animal protection advocates report that dissections constitute abuse of the animals dissected. The advocates state that what is learned by dissection could be more effectively learned by other means. Some science educators state…
