Describes applications of mechanical principles based on the theory of flight. Includes a discussion of aerofoils and lift, aircraft structures, aircraft performance, and laboratory experiments. (GS)

Describes a general chemistry level kinetics experiment requiring three 3-hour laboratory periods. Data analyses can be accomplished with graphical techniques or a non-linear least squares computer program. (MLH)

Describes an experiment in which general and physical chemistry students can determine the heat of vaporization of a volatile substance from experimental laboratory data using timesharing techniques. (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)

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)
