Describes a simple method for measuring the heat of vaporization of water, which gives results within five percent of the accepted value. (GA)

Explains a demonstration that shows the additive nature of light using three overhead projectors. (GA)

Describes a modified experiment to measure the internal resistance of an energy source, where a small resistance is connected in series with the source. (GA)

Describes a demonstration of P and S (longitudinal and transverse waves), using students' bodies as media, to explain seismic waves in a geology course. (GA)

Describes three simple experiments using Fermat's principle; a single reflection, Schwarz's triangle problem, and light triangle inscribed inside a circle. (GA)

Describes how the students of physics and drama have cooperated in an interdisciplinary project to produce a play, "The Physicists," in a high school. The purpose of the play is to promote artistic and analytical thinking. (GA)

Describes a game in which the symbol omega becomes equivalent to the word ohm, and is then modified or incorporated into a picture to represent a common word or phrase. Recommends the game as a way of humanizing the beginning course. (GA)

Describes a laboratory game called SUPERCHARGE, used as an aid to help students understand the concept of equipotential surfaces generated by distributions of charges. (GA)

Describes a few apparatuses and demonstrations for teaching physics under the headings: demonstrating resonance of the inner ear, constructing a potential well-hill for overhead projectors, rubber tube vacuum pump, improvement on the simple homemade motor, air track to demonstrate sailing into the wind, and center of gravity and stability. (GA)

Describes an experiment that used a four-element radio interferometer to illustrate gravitational deflection as predicted by the theory of general relativity. (MLH)

Relates various experiences that illustrate one teacher's way of dealing with teaching problems common in inner-city schools. (MLH)

Presents the complete 1974 Advanced Placement Physics B Examination and an answer key to the multiple-choice section. (MLH)

Reviews the basic principles and methods of nuclear chronalogy or radiometric dating. Includes rubidium-strontium dating, radiocarbon dating, and an outline of recent findings. (MLH)

Constructs a magnetic field model that illustrates by analogy the dynamic lift on an airplane wing. (MLH)

Presents the entire Advanced Placement Physics C Examination, intended to match the first two terms of a three-to-four term sequence of calculus-based physics courses for physical science or engineering majors. (MLH)
