Describes and compares three analytical methods of interpreting constant acceleration data from a stroboscopic picture or spark record. (CP)

Describes five ways for harnessing solar energy and lists references containing suggestions for classroom experimentation. (LS)

Experiments using soap films illustrate some of the most basic theorems concerning networks in a geometric framework. (SD)

Describes thin-layer chromatography experiments in which the students separate natural products, such as paprika, chile powder, and peppers. (MLH)

Describes an undergraduate chemistry experiment in which an atomic absorption spectrophotometer is used for recording flame emission spectra of the diatomic carbon molecule. (MLH)

Suggests that Experiment 13.2 (c) of the Nuffield 0-Level Chemistry Course be banned since the oxidation of lithium under very humid conditions can cause an explosion. (LS)

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)
