The number of flies that crawl through a small hole from one chamber to another is used to demonstrate principles of chemical kinetics. (CP)

The author describes a special experiment making peanut brittle and amusing activities based on chemical nomenclature used as motivational tools. (CP)

A baby-food jar is the constant in this group of ten basic science experiments. (Editor)

Offers questions to serve as an intellectual springboard for those involved in the planning, implementation, or evaluation of experimental colleges. (HS)

Describes a two-hour laboratory course entitled "Chemical Periodicity offered first semester of the freshman year. Three cation groups, one anion group, and a final unkown salt are qualitatively analyzed. Course fosters scientific thinking in experimentation by encouraging student-initiated schemes of analyses rather than "cookbook schemes. (RR)

Describes a student laboratory project involving the design of an "acoustic suspension speaker system. The characteristics of the loudspeaker used are measured as an extension of the inertia-balance experiment. The experiment may be extended to a study of Stelmholtz resonators, coupled oscillators, electromagnetic forces, thermodynamics and…
