Describes an experiment combining qualitative and quantitative information from hydrogen nuclear magnetic resonance spectra. Reviews theory, discusses the experimental approach, and provides sample results. (JM)

Introduces a procedure for a whole class of experiments which require very simple and inexpensive equipment and which illustrate one of the basic problems of chemical reaction engineering. The reactions are designed to allow development of a kinetic rate equation from laboratory data. (JM)

Describes a simplified diffraction experiment offered in a workshop with the purpose of illustrating to high school students the relation of science to society. The radii determined for cigarette smoke particles range from 0.2 to 0.5 micrometer in this experiment. Included is a description of the diffraction theory. (CC)

Discusses an experiment on the conservation of momentum and Q-values for elastic and inelastic collisions with frictional energy dissipation taken into account. Indicates that the apparatus is readily fabricated from easily available materials. (CC)

Discusses the construction of a diffractometer table and four microwave models which are built of styrofoam balls with implanted metallic reflecting spheres and designed to simulate the structures of carbon (graphite structure), sodium chloride, tin oxide, and palladium oxide. Included are samples of Bragg patterns and computer-analysis results.…

Discusses the use of a modified air table to conduct laboratory experiments which eschews research-oriented lab experience and concentrates on concepts learned in classroom. Includes a description of apparatus construction, sample instruction sheets, and a list of laboratory concepts with their relationships to classroom materials. (CC)

Speech presented at the Kentucky Foreign Language Conference in Lexington, April 29, 1969. (DS)

Safety procedures used by Department of Chemistry at the University of Akron are discussed. These include policy that no chemicals are stored in the teaching laboratories. Instead, dispensing stockrooms are used to service the laboratories. Other aspects discussed include ventilation procedures and development of microprocessor use in stockrooms.…

Two computer-oriented chemistry laboratory simulations are described. The material focuses on acid-base titration and an ideal gas simulation. (MP)

Safety education in the science classroom is discussed, including the beginning of safe management, attitudes toward safety education, laboratory assistants, chemical and health regulation, safety aids, and a case study of a high school science laboratory. Suggestions for safety codes for science teachers, student behavior, and laboratory…
