Analytical methods are reviewed for: alkali and alkaline earth metals; transition metals; precious metals; group 12, 13, 14, and 15 metals, nonmetals; radionuclides; multiple metals; anions; gases; chromatography; mass spectroscopy; photometry; sampling; volatile compounds; surfactants; detergents; pesticides; herbicides; and fungicides. (MVL)

Presents two demonstrations using the overhead projector: (1) describes how to build a projecting voltmeter and presents uses for the classroom; and (2) investigates the color of fluorescent solutions by studying the absorption and transmission of light through the solutions. (MVL)

This four-hour experiment uses a bee as a source of the enzyme which is reacted with a radioactive substrate to determine the specific activity of the enzyme. Uses thin layer chromatography, visible spectrophotometry, and liquid scintillation spectrometry (if not available a Geiger-Muller counter can be substituted). (MVL)

Describes a mouse skeleton reconstruction activity from owl pellets. Gives information about the materials, directions for students, and a five-day unit schedule. Provides some owl pellet sources. (YP)

Examines a 1988 National Science Foundation survey that found nearly 60 percent of space currently used for academic research is in need of repair. Warns that the problem continues to get worse as renovation funding is difficult to secure. Looks at other findings of the survey also. (MVL)

Provides explanations of 15 experiments, laboratory activities, demonstrations, and lessons for use in instruction. Includes information on Daphnia, wild garlic, crystals, gas chromatographs, bleaches, alcohols, reactivity series, chemistry formula, electronic keyboards and waveforms, interference and diffraction gravity, Moire fringe patterns,…

Presents information in brief on changing priorities in science education. Cites three categories of aims for science, traits of underachievers, and the processes of science. Includes reflections on the Salter's GCSE Scheme of Assessment, the integration of science and drama, and a historical perspective of practical work in school science. (RT)

Discusses two computer problem solving programs: rule-based expert systems and decision analysis expert systems. Explores the application of expert systems to automated chemical analyses. Presents six factors to consider before using expert systems. (MVL)

Reexamines the recommendations of "A National Action Agenda for Engineering Education." Cites at least one exemplary effort related to each. Covers the overburdened curriculum; practice oriented graduate programs; design, manufacturing, and construction; instructional laboratories; faculty pool, professional development for faculty;…

Discusses the need for determining a curriculum to provide qualified hazardous waste personnel. Describes the needed role of colleges and universities and current hazardous materials certification requirements. Lists requirements for 18 professional certifications. (MVL)

Discusses the least squares technique and states the difficulty in finding suitable examples for using it in the chemical laboratory. Provides several least squares equations and the accompanying three dimensional drawings. Notes graphic lecture aids are available from the author as either slides or overheads. (MVL)

Provides a first experiment for college chemistry that provides insights into scientific procedures without presupposing any detailed knowledge of chemistry on the part of the student. Requires the student to measure successive masses and volumes and use these values to determine the density from the slope of the graph. (MVL)

Considers three questions regarding computer science courses: (1) Can performance be predicted?; (2) Does a solid mathematical background provide the student with an advantage?; and (3) Is gender a factor in performance or aptitude? Reports a strong math background was related to achievement in a beginning course while gender was not related. (MVL)

Describes a laboratory experiment using AMPAC (a computer program) in conjunction with infrared spectroscopy. The experimental procedure and a list of questions for discussion are provided. Typical data are presented. (YP)
