Discusses a course at the University of Wisconsin-Eau Claire which improved instruction in physical hydrogeology, chemical hydrogeology, and water resources. Describes 14 laboratory activities including objectives, methods, and a list of equipment needed. (Author/MVL)

Investigates Japanese efforts to enter a new phase of its postwar technological period with a focus on internationalization of its economy and industry. Analyzes which technologies will dominate the early 21st century and their relationships to each other. (MVL)

Presented are two chemistry demonstrations: (1) an alternative method for the demonstration of the properties of alkali metals, water is added to small amounts of metal; (2) an exploration of the properties of hydrogen, helium, propane, and carbon dioxide using an open trough and candle. (MVL)

Examined are boys' and girls' achievement from a developmental perspective over the three years of science curricula. Results show the overachievement of girls relative to boys in both chemistry and physics in grades 10 through 12. Discusses implications of the results. (YP)

Notes that criticism of the training offered by universities to future chemists is well documented. Suggests a 17-step model for the planning of a chemistry course that utilizes a competency-based training program. Explains each step and lists sample objectives. (MVL)

Reviews some important properties of the bimolecular reaction between the hydroxyl radical and carbon monoxide. Investigates the kinetics of the reaction, the temperature and pressure dependence of the rate constant, the state-to-state dynamics of the reaction, and the reverse reaction. (MVL)

Describes the current use of automation in the laboratory. Discusses the need, flexibility, and benefits of automation. Presents a generic system description. Lists commercially available laboratory robots. (MVL)

Investigates specific strategies and activities used by two chemistry teachers to enhance student understanding of chemistry at the 11th- and 12fth-grade levels. Discusses teacher characteristics, class activities, classroom management, and monitoring for understanding. (YP)

Presented is a comprehensible structural representation of humic substances. A number of important roles of soil organic matter, including contribution to the cation-exchange capacity, binding of pesticides, and formation of complexes with micronutrient cations, are illustrated. (Author/CW)

Presents a programed method that inventories and classifies hazards. 8iscusses the following topics: (1) student and hazard source, (2) elimination of the source, (3) adaptation of the source, (4) isolation of the source, (5) adjustment of the surroundings, (6) isolation of man, and (7) personal protective equipment. (MVL)

Describes the peat to coal process. Investigates the organic, inorganic, and sulfur components of coal. Outlines how varying percentages of each are formed. (MVL)

Compares the abilities of pre-nursing and mainstream chemistry students in general chemistry courses. Finds no significant difference between the populations. Lists topics covered, representative test questions, and performance comparisons. (MVL)

Describes a chemical engineering course for senior undergraduates and first year graduate students in biochemical engineering. Discusses five experiments used in the course: aseptic techniques, dissolved oxygen measurement, oxygen uptake by yeast, continuous sterilization, and cultivation of microorganisms. (MVL)

Reviews two software packages: Graphical Analysis III and Lewis Diagrams. Finds Graphical Analysis III to be a fast and versatile graphing program for high school science classes with access to Apple II microcomputers. Lewis Diagrams is designed to aid in determining Lewis structures of molecules and ions for IBM computers. (MVL)

Describes a chemistry laboratory software package for interfacing the Apple IIe for high school and introductory college courses. Topics include: thermistor calibration, phase change, heat of reaction, freezing point depression, Beer's law, and color decay in crystal violet. Explains the computer interface and the tools needed.
