Describes: (1) demonstrations that have led to serious injury and should not be repeated; (2) demonstrations that are questionable because of the potential for injury; and (3) worldwide demonstrations that should be done, but done with care. Includes nature of potential/actual hazards, procedures used, and reactions involved. (JN)

Discusses a computer interfacing course using Commodore 64 microcomputers; a computer program for radioactive equilibrium; analysis of near infrared spectrum of hydrochloric acid molecules using Apple II microcomputers; microcomputer approach to conductivity titrations; balancing equations with Commodore 64's; formulation of mathematical…

Reports results of a survey of college professors (N=146) on the present use of chemical instrumentation in undergraduate chemistry curricula of four-year colleges and universities in the United States. Uses in general, organic, analytical, physical, integrated, and research chemistry courses are noted. (JM)

Describes an experiment designed to acquaint students with the theory and applications of anodic stripping voltammetry (ASV) as well as such ASV problems as contamination associated with trace analysis. The experimental procedure, instrumentation, and materials discussed are designed to minimize cost and keep procedures as simple as possible. (JM)

Presents an experiment in thermometric titration used in an analytic chemistry-chemical instrumentation course, consisting of two titrations, one a mixture of calcium and magnesium, the other of calcium, magnesium, and barium ions. Provides equipment and solutions list/specifications, graphs, and discussion of results. (JM)

Proposes a simple experiment based on the procedure of Guggenheim and Smith for the determinatin of the dipole moments of two isomeric compounds in nonpolar solvents. Provides background information, laboratory procedures, sample data, results of least squares analysis and discussion of results. (JM)

Presents viewpoints of two teachers about the importance of kinetics and how it contributes to students' understanding of chemistry. Discusses reaction rates, concentration effects, and temperature effects related to an understanding of dynamic equilibrium, molecular structure, and control of reacting systems. (JM)

Discusses two procedures for the identification of nitrate, the standard test ("Brown Ring" test) and a new procedure using triphenylbenzylphosphonium chloride (TPBPC). Effectiveness of both procedures is compared, with the TPBPC test proving to be more sensitive and accurate. (JM)

Presents a novel approach to identification of unknown alcohols using experimental measurements of boiling point and viscosity which are easily obtained without expensive equipment of instrumentation. Provides instructions for preparing capillary viscometer, listing special hints for obtaining good results. (JM)

Outlines use of electrode potential diagrams in a simple system and in the Hill-Bendall scheme for photosynthesis to help students understand reaction mechanisms involved. Emphasizes use of arrows to depict electron transfer, concept of free-energy diagram, and that maximum heights on diagrams represent maximum work available/minimum work…

Discusses a cooperative education program developed for undergraduate students who attend the university for five years, completing the requirements of their university degree as well as 24 months of work experience. Student, faculty, and industry roles in the program and some effects/results of the program are considered. (JM)

Reviews a noncommercial educational game (Polymerlab) and changes made in GASLAWS (adaptation of mainframe program used in computer-assisted instruction). Describes programs on simulation of molecular speed distributions; interfacing microcomputers to make laboratory measurements; a course in microcomputer-instrument interfacing and measuring and…

Reviews important science news stories reported during 1984 in "Science News" magazine. These stories are in the categories of: anthropology and paleontology; behavior; biology; chemistry; computers; mathematics; earth science; the environment; medicine; physics; science and society; space sciences and astronomy; and technology. (JN)

Organic chemistry students (N=64) completed questionnaires requesting demographic data; data on ability, previous science courses, attitudes toward self when studying chemistry, attitudes toward chemistry; and preference, difficulty, and importance of chemistry compared to other courses. These data are used to develop a profile of the successful…

Describes the chemistry program in a high school which operates on a modular schedule. Each module is 20 minutes long, and there are 21 modules in a school day. Student success in the program is credited to the modular schedule and to use of learning activity packets (which are also described). (JN)
