Described is a physics experiment in which small bits of metal on a water surface will move towards, and away from an electrostatically charged rod. The explanation for the motion of the metal bits deals with their shape and the electrical force on the water surface. (SL)

Described is a physics experiment which investigates the reactions occurring when a hot dog is fried or broiled. (SL)

Described and evaluated is a new wave form analyzer and an electrolysis apparatus. (SL)

Presented is the index to The Physics Teacher journal for January-December 1976 (Volume 13). Index is by subject and by author. (SL)

Discusses teaching the minimization of area and distance, such as finding the minimum length of expressway connecting four cities by using an analogy of a soap film between two Lucite plates. (MLH)

Discusses the historical background of the 1887 Michelson-Morley experiment to detect the earth's motion through the aether. (MLH)

Describes the construction and application of two new types of detectors that use the discharge provoked in a gas by the passage of a charged particle as the means of detection. (MLH)

A physics professor discusses how his personal view of science has changed over 20 years; includes views on the esthetic and practical aspects of science and the way science influences one's world view. (MLH)

Examines the mathematics of the exponential function and some examples of its application in analyzing inflation. (MLH)

Describes a physics experiment in single and multiple slit diffraction and interference phenomena that illustrates the existence of diffraction gratings in many common objects. (MLH)

Describes the construction and application of a device small enough to be worn on a worker's clothing that can monitor exposure to mercury. (MLH)

Describes an electronic digital counter, a speed-of-light experiment using a television, a simple out-of-circuit method for determining if a transistor is made of silicon or germanium, and the use of dry cells to power TTL integrated circuits. (MLH)

Reviews the principal sources of natural and man-made radiation, current representative levels of radiation exposure in our daily lives, and possible harmful effects of this exposure. (MLH)

Reviews the kinematics of plucked, hammered, and bowed strings, and suggests demonstrations including some that show how musical string vibrations can be related to one another. (MLH)

Describes a high school physics course taught by independent study during one-half of the class time. Discusses the use of student projects, minicourses, term papers, and do-it-yourself field trips. (MLH)
