Procedures for two demonstrations are provided. The solubility of ammonia gas in water is demonstrated by introducing water into a closed can filled with the gas, collapsing the can. The second demonstration relates scale of standard reduction potentials to observed behavior of metals in reactions with hydrogen to produce hydrogen gas. (Author/JN)

Evaluates experiences gained using nontraditional teaching methods in college physical chemistry, including small group instruction, use of teacher prepared materials, integration of theoretical and directed teaching, continual examination of knowledge and less emphasis on teacher centered approaches. Suggests positive influences resulting from…

Explains the need for methods of increasing students' and administrators' awareness of safety procedures in the chemistry laboratory. Suggests increasing formal courses in safety and cites difficulties inherent in increasing safety courses including the lack of funding and an already overcrowded chemistry curriculum. (DS)

Supplies information regarding modification of the laboratory to facilitate mobility-handicapped students in college chemistry, including the accommodation of students lacking motor control in the arms and hands. Also discusses modifications to allow these individuals access to library resources, financial concerns, and mobility-impaired…

Outlines considerations in the design and modification of college chemistry laboratories to accommodate the motor impaired student. (CS)

Reviews safety records of physically handicapped individuals, relating safety for all individuals in the laboratory to special concerns for the mobility handicapped, visually handicapped, and hearing impaired individuals. Discusses legal responsibilities and liability. (CS)

Details are provided about project SERAPHIM which is aimed at setting up a model system for dissemination of instructional materials in chemistry. Many of the instructional modules that will be handled by the project will be computer-based, with an emphasis on microcomputer-based materials. (MP)

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.
