A survey of 129 science and technology-related centers and museums revealed a shortage of polymer chemistry exhibits. Describes those displays that do exist and suggests possibilities for future displays and exhibits. Contains 23 references. (WRM)

Described is a one-week summer chemistry workshop held at Lebanon Valley College, Annville, Pennsylvania, for secondary school students. Experiments and evaluation results of the workshops are provided. (HM)

Presents a collection of articles to provide chemistry teachers with resource materials to add forensic chemistry units to their chemistry courses. Topics range from development of forensic science laboratory courses and mock-crime scenes to forensic serology and analytical techniques. (JN)

Discusses the various ways that textbooks treat the energetics of protein synthesis. Offers an approach to explaining the phenomenon by emphasizing the ordering aspects of the process. Describes the participation of compounds such as ATP and GTP in the ordering process. (TW)

Discusses areas of concern for faculty development in the sciences, including: (1) knowledge of computers, (2) subject matter knowledge; (3) correlation of the delivery of faculty development programs with individual needs, (4) responsibility for science faculty development in terms of available supports. (CS)

Describes a system of heuristics for problem solving and instructional methods for presenting it to secondary school students. (CS)

Reviews properties, geologic occurrences, availability to plants, and cycles of the element selenium. (CS)

Lists equipment and materials needed and procedures for analyzing soil, in which secondary school students experience practical applications to acid-base reactions, pH, oxidation-reduction, precipitation and solubility. (CS)

Presents three different procedures in which reagents are added in a specified order to a large beaker containing an aqueous solution of nickel sulfate. Complex ions of nickel (II) are prepared by using aqueous solutions of ammonia, ethylenediamine, dimethylglyoxime, and cyanide ion. (CS)

Describes a physical chemistry experiment that introduces undergraduate students to the entities of polyelectrolytes. (CS)

Presents a chemical instrumentation laboratory experiment that introduces the methodology of the fabrication and evaluation of an ion-selective electrode. (CS)

Presents methods by which undergraduate students gain practice in ESR spectroscopy. (CS)

Outlines a procedure where chromatographic separation can be easily done and provides an introduction to column chromatography. (CS)

Describes how Gibbs valley graphs can clarify the relation between the Gibbs function and chemical equilibrium. Gives examples from gas phase equilibria. (CS)

Presents information concerning a fundamental concept for understanding reaction rate, the idea of a rate-limiting step for a chemical reaction. Discusses problems in using flow analogies and introduces an alternative approach to finding the rate-limiting step based on locating the transition state of highest energy. (CS)
