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)

Describes an approach which emphasizes the physical aspects of periodic phenomena, and is explicit about whether the time or space domain is being treated. (Author/GS)

Illustrates a safe and easy way of igniting a hydrogen-oxygen mixture and lists the equipment used. (BR)

Describes how you can lead students to erroneous inferences and conclusions by using demonstrations which point out to students the importance of carefully distinguishing between observations and inferences. (BR)

Describes a chemistry curriculum for college freshmen that uses laboratory study of the chemical composition of meals eaten by students as the central activity from which theoretical and practical learning are derived. Presents a meal analysis flow diagram and a table of concepts included in the program. (GS)

Describes the inexpensive construction of an uptake volume potometer uptake and loss potometer, and experiments on plants that can be conducted with the equipment. (BR)
