Presents specific techniques for lectures and demonstrations in acoustics for deaf students. (SK)

Presents two examples of physics demonstrations: (1) vibrating aluminum rod suitable for use in a small room, and (2) vibrating white rubber tubing suitable for use with larger audiences. (SK)

Presents a classical demonstration of polarization for high school students. The initial state of this model, which demonstrates the important concepts of the optical and quantum problems, was developed during the 1973 summer program on lecture demonstration at the U.S. Naval Academy. (HM)

Describes a type of individual laboratory-activity examination developed for use in an undergraduate general physics class whose enrollment was more than 100 persons. Test preparation, procedure, evaluation, and outcomes are discussed. (BT)

Describes how to measure Brewster's angle using Polaroid sunglasses and the reflection of the ceiling light on a polished floor. (GA)

Presented is an experiment which provides a study both of the end correction involved with open pipes and also of the effect that varying the size of the tone hole in the pipe has on its fundamental frequency. Discussed are equipment, formulas, background, and methods. (CW)

Presents two demonstrations: heatwave focusing by concave reflectors and wave speed on a string. Describes the apparatus, and procedures for the demonstrations. (YP)

Introduces a method for two-dimensional kinematics measurements by hanging marbles with long strings. Describes experimental procedures for conservation of momentum and obtaining the coefficient of restitution. Provides diagrams and mathematical expressions for the activities. (YP)

Demonstrates the inverted image, the chromatic aberration, and the floaters of the eye using an opaque 35mm film container with a small pinhole poked through the bottom. Describes the observation of Haidinger's brushes using polarized light. (YP)

Discusses a demonstration of interference phenomena using three sheets of polaroid material, a light source, and a light meter. Describes instructional procedures with mathematical expressions and a diagram. (YP)

Describes an air track experiment demonstrating the transfer of mechanical energy from elastic potential to kinetic. Discusses four methods for calculating energy stored in the spring. Included are pictures, typical data, and graphs. (YP)

Describes the use of the black-box technique to explore electrical circuit design and circuit elements. (JRH)

Describes a computer-based prelaboratory lecture to replace traditional lecture. Discusses how the CUPLE method was developed, the course structure, and a typical course day. (MVL)

Presents an experiment that makes manifest the energy lost to friction of an iron ball moving along an inclined iron rail, which allows students to compute the rolling friction coefficient. Uses a method based on measurement of deformation produced in a piece of Plasticine by an inelastic collision with the ball and combines mechanical concepts…

Describes a method to create holograms for use in different interferometry techniques. Students utilize these techniques in experiments to study the structural integrity of a clarinet reed and the effects of temperature on objects. (MDH)
