Brush, Stephen G. – Physics Teacher, 1985
Shows that important discoveries in physical sciences cited in textbooks were made by women, although they may not be given credit for their work. Also discusses the contributions of 10 female scientists to provide role models for students. (DH)
Descriptors: Chemistry, College Science, Females, Higher Education
Peer reviewed Peer reviewed
Brancazio, Peter J. – Physics Teacher, 1985
Illustrates the differences between explanations of projectile motion by a physics teacher and a baseball player. Equations are discussed and results are shown graphically. (DH)
Descriptors: College Science, High Schools, Higher Education, Motion
Peer reviewed Peer reviewed
Bartlett, Albert A. – Physics Teacher, 1985
Discusses the velocity of an orbiting satellite. Knowledge of the kinematics of falling objects is the only prerequisite for understanding the concepts considered. (DH)
Descriptors: College Science, High Schools, Higher Education, Motion
Peer reviewed Peer reviewed
Wood, Charles – Physics Teacher, 1985
Provides a reproducible flow chart to aid students in problem-solving skill development. Steps include: determining what is asked; choosing a relationship; and checking validity of the relationship. Teacher notes are given to improve instruction. (DH)
Descriptors: Flow Charts, High Schools, Physics, Problem Solving

Goldberg, Fred M. – Physics Teacher, 1985
Discusses refraction in terms of the deviation of light. Points out that in physics courses where very little mathematics is used, it might be more suitable to describe refraction entirely in terms of the deviation, rather than by introducing Snell's law. (DH)
Descriptors: College Science, Higher Education, Light, Optics

Minnix, Richard B.; Carpenter, D. Rae, Jr. – Physics Teacher, 1985
Describes: (1) the construction of a variable-volume resonator and Raleigh-disk resonance detector from simple materials; and (2) a learning aid for performing 60 experiments in basic electricity and electronics (consisting of a circuit board, components, and mask sheets). Illustrative experiments are included for both apparatus. (DH)

Corwin, T. Mike; Wachowiak, Dale – Physics Teacher, 1984
Although the Einstein-Podolsky-Rosen experiment was originally a hypothetical situation, John Bell was able to apply a version of their argument to an experiment that could actually be done. This experiment (called "Bell's Inequality") and a hypothetical experiment analogous to the one Bell proposed at the atomic level are described. (JN)

Peer reviewed Peer reviewed
Graef, Jean – Physics Teacher, 1984
Discusses the realities of implementing a computer-assisted program in high school level science classes, offering some practical suggestions for making such a program successful. Also includes information on several software packages for interfacing microcomputers to sensing equipment. (JN)
Descriptors: College Science, Computer Oriented Programs, Computer Simulation, Computer Software

Crane, H. Richard, Ed. – Physics Teacher, 1984
Discusses the physics principles applied to the main steps of the photocopying process. Of particular interest (and at the heart of the process) are the ways in which electric charges, or particles carrying charges, are caused to transfer from one surface or medium to another at each stage. (JN)
Descriptors: College Science, High Schools, Higher Education, Physics

Iverson, Donald; Insley, Peter – Physics Teacher, 1984
Describes a demonstration in which the pattern on a rotating turntable can be affected by humming and adjusting the pitch of the hum. At some frequency, if conditions are right, the pattern can be stopped, or "strobed." Also describes a way to introduce humor into physics instruction. (JN)
Descriptors: College Science, Demonstrations (Educational), High Schools, Higher Education
Peer reviewed Peer reviewed
Edge, R. D., Ed. – Physics Teacher, 1984
Experiments which illustrate the effect of humidity on human hair and on paper are described. Also described are two ways to make a hygrometer. These methods were found in a series of British television programs (also available in the United States). Comments on the programs are included. (JN)
Descriptors: Elementary School Science, Elementary Secondary Education, Humidity, Physics
Peer reviewed Peer reviewed
Payne, Mark M. – Physics Teacher, 1984
Describes how a planetarium was constructed on the ceiling of a traditional physics laboratory. Similarities and differences between the "poor man's" planetarium and other planetariums are noted. (JN)
Descriptors: Astronomy, High Schools, Physics, Planetariums
Peer reviewed Peer reviewed
Minnix, Richard B.; Carpenter, D. Rae, Jr. – Physics Teacher, 1984
Describes an apparatus which demonstrates the stability of equilibrium of multidimensional objects and helps students to understand the concept of a lever arm. Also describes an alternative to the standard black, mercury "student cell" used as a reference voltage for calibrating a slide-wire potentiometer. (JN)
Descriptors: College Science, Demonstrations (Educational), Electricity, Force

MacKeown, P. K. – Physics Teacher, 1984
Clarifies two concepts of gravity--those of a fictitious force and those of how space and time may have geometry. Reviews the position of Newton's theory of gravity in the context of special relativity and considers why gravity (as distinct from electromagnetics) lends itself to Einstein's revolutionary interpretation. (JN)
Descriptors: College Science, Force, Geometry, Gravity (Physics)
Peer reviewed Peer reviewed
Jones, Gordon E. – Physics Teacher, 1984
Describes a college-sponsored physics competition which benefits both high school physics teachers and students. The competition (a paper/pencil examination) is open to students of all abilities and provides an opportunity for teachers to meet and exchange ideas on a yearly basis. (JN)
Descriptors: College School Cooperation, Competition, Cooperative Programs, High Schools
