Describes a computer simulation experiment in which physical chemistry students can determine all of the kinetic parameters of a reaction, such as order of the reaction with respect to each reagent, forward and reverse rate constants for the overall reaction, and forward and reverse activation energies. (MLH)

Describes an organic chemistry experiment in which seven possible mechanisms for the isomerization reaction are tested with simple sense observations and melting point determinations. (MLH)

Five teaching experiments with French songs, in grades 7, 8 and 9, are described. Aural understanding was practiced first, then use of the text. In the 9th grade, work on the content became most important, with the aim of correcting and expanding the common conception of France. (Text is in German.) (IFS/WGA)

Describes the process for determination of the constants from data obtained with a hydrogen-deuterium light source and Ebert plane grating spectrograph. (Author/CP)

Includes a discussion of the structure of some molecules and the design of an experiment to replace CHEM Study Experiment 7. (GS)

Describes the experimental apparatus and method for the study of magnetic vector potential (MVP). Includes a discussion of inherent errors in the calculations involved, precision of the results, and further applications of MVP. (GS)

Describes material modified from the Nuffield advanced chemistry course to make it meaningful and relevant to pupils in the middle school. Discusses a series of simple experiments on apple browning and summarizes the browning process and its control. (Author/GS)

Describes differences in the construction of a colorimeter and a photometer. Gives examples of ways in which light-measuring instruments can be used by biologists. These examples can be used either as class experiments or as individual projects. (GS)

Describes the life cycle and control of the greenhouse whitefly. Explains the culture of the whitefly for school use and presents a list of laboratory exercises that can be done in a double period. (GS)

Describes laboratory procedures for culturing drosophila and for observing their behavior. Outlines drosophila response to stimuli and explains the courtship sequence. (GS)

Describes an experiment at Birkbeck College, University of London, designed to encourage the spontaneous, uninhibited use of French by students. (PMP)
