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)

Described is a secondary level physics laboratory course designed to teach analytical thinking. Included is an analysis of a typical activity requiring the student to create and complete his own experiment. (SL)

Described is a device for demonstrating photoelasticity, utilizing an overhead projector. (SL)

Describes a successful laboratory program in reprographics (involving two one-unit courses) which allows unlimited enrollment, individualized instruction when needed, and an opportunity to develop desirable work habits and traits for an office employee. Precautions to consider before accepting or developing such a program are offered. (HD)

This audiotutorial course consists of 35 minicourses including biology, husbandry, and diseases of the common laboratory animals. Each minicourse includes an audiocassette tape recording and visual and written materials. The course is available for distribution. (Author/LBH)

These worksheets involve using tangram pieces to create geometric shapes and to determine area relationships. (DT)

Outlines the discovery and nature of ultraviolet light, discusses some applications for these wavelengths, and describes a number of experiments with ultraviolet radiation suitable for secondary school science classes. (JR)

Describes a laboratory exercise in ethology that has proven to be successful in teaching the analytical power of biological observation to students at the University of Wisconsin. (JR)

Briefly discusses the theory of fatigue, and describes ways in which the fatigue rate in humans can be measured in the classroom using a simple physiological instrument, the ergometer. (JR)
