Dental caries (tooth decay) and periodontal (gum) disease are treated/prevented by procedures utilizing chemical expertise. Procedures and suggestions on how they might be incorporated into the high school chemistry curriculum are described. Specific topics discussed include dental caries, fluoride, diet, tooth decay prevention, silver amalgan,…

Background information, materials/procedures, and results are provided for an undergraduate laboratory experiment on a photochemical ligand substitution reaction using sunlight. The experiment illustrates demonstration of photochemistry and basic mechanisms of transition metal reactions using inexpensive materials and is easily followed by…

Describes safety committee (New York section, American Chemical Society) survey of college chemistry facilities to assess hazards and make recommendations, and a cooperative project in Iowa to identify and remove hazardous chemicals from college/secondary school classrooms. Includes a partial list of hazardous chemicals identified by the Iowa…

Describes the rationale for and typical activities of a training program/course (Project TEACH) for teaching assistants. Includes titles of modules used and the nine-week 1979 course schedule. Concludes with selected student comments and suggestions about the course. (SK)

Describes some impurity-related optical properties of semiconductors, with special emphasis on the luminescence of zinc sulfide (ZnS). Presents and interprets five experiments using a ZnS screen, ultraviolet lamp, transparent Dewar liquid nitrogen, and a helium/neon gas base. Includes application of luminescence measurements to archaeology. (SK)

Described are some of the technical, military, and political considerations that bear most directly on the choices facing the United States and its NATO allies on modern lethal chemical weapons. (BT)

Proposes an interdisciplinary curriculum focusing on chemistry with a central theme of pollution--of the human body and its surroundings. Appropriate readings, films and music, art and photographs are suggested for the topics of environmental pollution, pharmacology, and toxicology. (CS)

Presents the author's reasons for supporting the CHEMS program. Also characterizes aspects of his teaching regarded as significant in teaching chemistry, including prompt return of assignments, test retakes, videotaping. inclusion of organic chemistry, ability grouping of students, avoidance of specialization, and departmental testing. (CS)

This article presents discussions dealing with the latest analytical and bioassay methods for environmental assessment. Presented is a phased approach for the integration of methods in environmental assessment. (RE)

Some aspects of the reform of chemical education in the Netherlands are presented. These aspects include the reason for the reform and the results of the effort. Examples regarding the way entropy is treated and the treatment of quantitative chemical problems are given. (Author)

Suggestions are offered to illustrate concepts and processes by using simple materials such as paper, paper clip, rubber band (bonding, entropy, endothermic processes). Also suggests using basic terminology: elementary ratios, percent, reaction chemistry for entropy function; equilibrium constants for Gibbs energies; and chemical mechanics for…

Two presentations at the 1981 International Conference on Chemical Education are summarized: (1) issues related to chemistry curriculum development in Brazil and (2) types of knowledge "sub-cultures" (for example, theorists, empirists, applicists, pedagogists, or epistemologists) would foster in chemistry curricula. (JN)

Industrial chemistry in general and catalysis in particular should be included as part of college chemistry curricula. (JN)

Describes a modified Keller plan for teaching a biochemistry laboratory course and evaluates the method's effectiveness by comparing results of students using Keller plan (N=17) to students receiving traditional instruction (N=16). Results suggest the modified Keller plan is a successful instructional method for the course. (Author/SK)

A one-semester biochemistry course was developed as an alternative to traditional freshman chemistry. Lecture topics and laboratory exercises focus on the course's unifying theme of the origin and early stages of the evolution of life on earth. (Author/SK)
