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 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)

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

Describes the step-by-step preparation of skins and explains their storage procedures and uses. Illustrative photographs are included. (LS)

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

Describes a course which used a student project approach and was designed to replace traditional instrumental analysis. Presents the criteria used for project selection and gives examples of student projects in 1974. (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)
