Describes a synthesis laboratory that is a two-semester sequence for students who have had general chemistry as well as prior or concurrent experience with organic chemistry. Outlines the compounds synthesized, techniques used, and possible special projects. (GS)

Describes an experiment designed for second-level summer school chemistry students enrolled in Great Britain's Open University. (GS)

Presents an alternative series of investigations replacing the propanone-trichloromethane system (Topic 10) in the Nuffield A-Level course. A trichloromethane-ethyl ethanoate (acetate) system presented in four experiments give good results and removed the dangers arising from the other system. Topic 10 need not be re-written, just the replacement…

Examples of activities involving geometric construction are suggested for discovery-oriented instruction. (SD)

Describes an approach which begins with observations and systems familiar to the student and proceeds to develop and test models to explain them. Experimental topics include Brownian motion, a germinating cell, phase change of p-dichlorobenzene, extension and contraction of rubber, and an enzyme system. (GS)

The relationship between area and perimeter is presented through a series of laboratory-type activities and demonstrations. (SD)

Includes a syllabus for lecture and laboratory in a course emphasizing principles of operation rather than trouble shooting. (GH)

Describes a survey of experiments including a stringed instrument experiment and discusses other instructional uses of cartridges. Includes information on the characteristics of cartridges. (GH)

Describes a take-home experiment requiring only running water, a flat surface, a fluorescent light, and a ruler. Suggests elaboration of the experiment. A photograph is included. (GH)
