Discussed are the needs and objectives that should be evolving in biology education to meet the needs of modern students. Stressed are the principles of curriculum integration, relevance, cultural fitness, and adaptation. Directions for educational reform are described. (CW)

Discusses the hypothesis that similarities may exist between laboratory research paradigms evoking elevated blood pressure during task performance by normal subjects and video display terminal (VDT) work done by data clerks and college students. Type A behavior and the development of coronary heart disease are discussed, and further research needs…

Described are the uses of a spreadsheet program to compute the free energy change associated with a reaction; to model acid/base equilibria; and to solve equilibrium constant expressions. Stressed are the advantages derived from having the spreadsheet perform the multiple, trivial calculations. (CW)

Presented is a simple laboratory set-up for teaching microprocessor-controlled data acquisition as a part of an instrumental analysis course. Discussed are the experimental set-up, experimental procedures, and technical considerations for this technique. (CW)

Developments in microscale chemistry which have occurred in the late 1980s are reviewed. Possible directions for the future concerning the uses of microscale chemistry in organic, general, and high school chemistry are suggested. Twenty-three references are listed. (CW)

Develops an exercise in which students use magnetic-profile data gathered in the South Pacific to test the Vine-Matthews-Morley hypothesis. Uses the Eltanin 19N and 20N profiles. Relates the exercise to 20 current geology texts. (MVL)

Proposes an approach to school laboratory experiences which leads to gradual acquisition of inquiry skills based on the idea of advance organizers. Presents a design which is context familiar and can serve as an introduction to scientific inquiry. Discusses student achievement, and teacher and student attitudes. (CW)

Describes two oscillating reactions: the Briggs-Raucher reaction using H202, KIO3, malonic acid, and MnSO4 which changes from yellow to blue, and the Belousov-Zhabotinskii reaction uses NaBrO3, NaBr, malonic acid, and ferroin solution and changes from red to blue. Includes a third color demonstration on the six oxidation states of manganese. (MVL)

Illustrates an interesting biomedical application of adsorption from solution and demonstrates some of the factors that influence the in vivo adsorption of drug molecules onto activated charcoal. Uses acetaminophen and N-acetylcysteine for the determination. Suggests several related experiments. (MVL)

Describes several experiments using the techniques of thermal analysis and thermometric titrimetry. Defines thermal analysis and several recent branches of the technique. Notes most of the experiments use simple equipment and standard laboratory techniques. (MVL)

To avoid a tedious task for recording temperature, a computer was used for calculating the heat of crystallization for the compound sodium thiosulfate. Described are the computer-interfacing procedures. Provides pictures of laboratory equipment and typical graphs from experiments. (YP)

Discussed are general considerations for educating visually impaired students including planning, testing, lecture/discussion, field trips, and laboratory activities. Fourteen activities that have been adapted are described. One such undergraduate course is described. (CW)

Described is a workstation equipped with a personal computer and a research-quality data-acquisition interface for instrumental data acquisition and analysis for chemistry and physics courses. Hardware, software, and functions of the apparatus are discussed. (CW)

Presented is an illustration of the use of a computer spreadsheet program, Microsoft Excel version 1.5, for solving complicated chemical problems. Examples of spreadsheet output are provided. (CW)

Reviewed is the discovery, nuclear and chemical properties, and uses of an isotope of Americium (Am-241). Production and separation techniques used in industry are emphasized. Processes are illustrated in flow sheets. (CW)
