Investigated is the value of preliminary high school experiences in physics and chemistry. Results indicate that the grades of students with more high school experience are no better than those of students with less experience and that less experienced students spend more time studying and take better advantage of tutors.

Brooklyn College faculty members in English and chemistry guest teach in each other's core curriculum class, linking scientific and social literacy in traditionally separate courses, creating an arena in which non-science majors can effectively learn science. (MSE)

Notes that the number of workers employed in the U.S. chemical industry rose again in 1988. Provides information for the years 1978-88 for the areas of industrial employment, scientist and engineer employment, corporation employment, wages, and industrial productivity. (MVL)

Discusses a history exhibit of the American Chemical Society, now on national tour. Focuses on lecture to laboratory, chemistry in early America, the Civil War era, the research model, the early twentieth century, the post-war era, textbooks, and the recent past. (MVL)

The purpose of this study was to develop a procedure for the evaluation of M-demand of chemistry problems. It was shown that dimensional analysis upon the Neo-Piagetian theory of Pascual-Leone could help science teachers to understand the epistemological basis of their discipline. (CW)

Describes a three-week summer program teaching selected chemistry faculty how to incorporate polymer chemistry into chemistry courses. In addition to lectures, the program conducted many experiments and provided a trip to industry laboratories. (YP)

Discusses the selection of gloves for the chemistry laboratory. Provides checklists for the purposes of the gloves, and the factors including permeation rate, breakthrough time, friction, and cost. Lists eight rules for preventing skin exposure and minimizing area contamination. Lists six references. (YP)

Provided are two demonstrations for an introductory course in chemistry. The first one emphasizes the observation and the interpretation of facts to form hypotheses during the heating of a beaker of water. The second demonstration shows the liquid phase of carbon dioxide using dry ice and a pressure gauge. (YP)

Describes 10 experiments for characterizing the chromium complex Reinecke's Salt. The properties of the complex, experimental procedures, and a discussion are provided. Analyses are presented for chromium, total ammonia, thiocyanate, ammonium ion, and hydrate water. Measurement methods are described. (YP)

Examines the possibility that part of the problem in the teaching of physical science may lie in teaching-learning materials. Selects 14 chemistry textbooks and 14 physics textbooks in Australia. Analyzes them based on learning theory and scientific literacy. (YP)

Describes an experiment in which a simple laser-based apparatus is used for measuring the change in refractive index during the acid-catalyzed hydrolysis of glycidol into glycerine. Gives a schematic of the experimental setup and discusses the kinetic analysis. (MVL)

Discusses an enzyme kinetics laboratory experiment involving a two substrate system for undergraduate biochemistry. Uses the enzyme gamma-glutamyl transpeptidase as this enzyme in blood serum is of clinical significance. Notes elevated levels are seen in liver disease, alcoholism, and epilepsy. Uses a spectrophotometer for the analysis. (MVL)

Statistics are provided from an annual survey of members of the American Chemical Society highlighting their economic status. Included are employment, salaries, industry comparisons, and academic comparisons. The lower status of women's salaries in chemistry is noted. (CW)

Reviewed is the disappointing performance of the U.S. team at the 1989 International Chemistry Olympiad. Reasons for this performance and a description of the U.S. team are presented. (CW)

Provides a physical description of semivolatile organic compounds (SVOCs), both in terms of their characteristic nature in the atmosphere and the processes which control their deposition. Contains a summary of the requirements for a full assessment of atmospheric SVOCs and their deposition. (LZ)
