This article, intended for college organic chemistry students, discusses how chiral pheromones are synthesized from glumatic acid. (HM)

Thermoluminescence and its application to archeological dating are considered in this article. Descriptions are given of the method, the required doses, absolute and relative dating, complications, and the relation of this type of dating to other methods. (SA)

Presents a general introduction to microprocessors and microcomputers. Guidelines for purchasing software and hardware are intended to familiarize potential buyers with the current equipment on the market and the terminology in use. (SA)

Discusses the Pauling electronegativity concept which rationalizes several kinds of chemical reactions of covalent substances. Electronegativity differences applied to some reactions are demonstrated. (SA)

Focuses attention on the almost universal practice of discussing all metals as malleable. The author points out that some are brittle and then he presents the variation in chemical properties of metals. (SA)

Various phenomena in chemistry and biology can be understood through Gibbs energy utilization. Some common phenomena in chemistry are explained including neutralization, hydrolysis, oxidation and reaction, simultaneous dissociation equilibrium of two weak acids, and common ion effect on solubility. (Author/SA)

An explanation of strong base effect demonstrates that deprotonation of a reactant shifts an equilibrium toward reactants in the same way that a deprotonation of a product shifts it towards products. (Author/SA)

An inorganic chemistry course at the Free University of Amsterdam is part of an integrated program involving practical work and theoretical study for chemistry students. Twelve experiments are required and 11 are performed by students in groups of fours. (Author/SA)

Describes a short course for parents and children in grades 5-8. Fundamental concepts of chemistry are the focus of the experiments described. (SA)

A course is described that is designed to encourage exploration, conceptual invention, and expansion of an idea. Results are given that relate to curricular experimentation with chemistry. (SA)

This column for high school teachers, written by high school teachers, discusses several interesting anecdotes related to the formulation of laws and the determination of constants. Science history is presented in a manner that can enliven classroom presentations and aid in understanding the principle itself. (Authur/SA)

Catalysis is defined and discussed as the process relates to science history, chemical reactions, enzymes, industry, catalytic reactors, and catalyst preparation. (SA)

Discusses the energy processes required to sustain life. Diffusion, oxygen transport, oxygen in arterial blood, and carbon dioxide transfer are the topical subdivisions discussed. (SA)

Presents the plans for constructing a mode 2 TOPS Projector-adaptor, which costs one-half that of a model described in an earlier article. The author uses a step-by-step approach to the project. (SA)

Describes the use of cassette tape recordings in preparing freshman chemistry students for experiments in laboratories. The tapes are said to have decreased student anxiety in the laboratory and increased laboratory skills. (SA)
