Measurement of harmonic amplitude and phase response are discussed, focusing on an instrument used to demonstrate motion of a damped system when oscillating freely and motion of the same system when driven into harmonic oscillation. Includes procedures, sample results, and comparison of results to values calculated from geometry of the system. (JM)

Describes a soap bubble motor, house insulation models, using hot-water bottles as heat sources, solar mobile, surface tension boat, evaporative cooling experiments, six activities on heat, and a magic trick based on friction. Also discusses using the Cambion Electronics Kit to introduce junior high students to the subject. (JM)

Presented are abstracts of five papers on teaching materials/methods presented at the 35th annual meeting of the American Physiological Society. Topic areas include expert system used as a teacher/consultant in hemostasis problems, computer assisted testing, and excitation/conduction properties of membranes as illustrated by the compound action…

A laboratory experiment that involves solving problems with conflicting evidence or inconsistent data. The experiment gives students opportunities to reason as scientists. (EB)

Describes an experimental biochemistry course designed to teach basic biochemical techniques using an unstudied enzyme as the experimental material. Explains the schedule of experiments designed for the course and lists the sources used. (GS)

Described are eight chemistry experiments and demonstrations applicable to introductory chemistry courses. Activities include: measure of lattice enthalpy, Le Chatelier's principle, decarboxylation of soap, use of pocket calculators in pH measurement, and making nylon. (SL)
