Examines the treatment of errors and significant figures in physics manuals as part of an evaluation of these instructional materials. Comments on specific materials reviewed are provided. (JN)

Presents a table cross-referencing 12 physics laboratory manuals by topics. Topic areas include measurement and techniques, mechanics, molecular physics, waves and optics, electricity and magnetism, and quantum physics. (JN)

Discusses use of a tangential gun to obtain a value for the specific electronic charge e/m. The method is the one advocated by the tube suppliers, though some suggested variations may appeal to teachers anxious to train their students in thinking along lines that are both scientifically correct and practically desirable. (JN)

Discusses a computer simulation which: (1) describes an experiment investigating F=m/a; (2) generates data; (3) allows students to see the data; and (4) generates the equation with a least-squares fit. (JN)

Materials needed and procedures for conducting two activities are provided. The first investigates drops of a liquid which float on water in a watchglass resting on top of a loudspeaker. The second investigates electromagnetic phenomena. (JN)

If a ball were given an initial velocity in excess of its terminal velocity, would the upward force of air resistance (a function of velocity) be greater than the downward force of gravity and thus push the ball back upwards? An answer to this question is provided. (JN)

Describes an apparatus for viewing one- and two-dimensional collisions and coupled pendulums on an overhead projector. Suggested demonstrations for the two-dimensional colliding balls and for the two-dimensional coupled pendulums are provided. (JN)

Reviews software package consisting of three programs designed to give students practice on V=IR calculations for series, parallel, and network electric circuits. Indicates that the package for Apple II microcomputers is very good for individual practice and that graphics are useful in teaching students how to draw circuits. (JN)

Provides author and subject indexes for material appearing in "The Physics Teacher" during the years 1963 to 1980. Subject index is arranged alphabetically by major and minor topic areas. (JN)

Discusses use of the fine-beam cathode-ray tube to investigate strength and direction of the earth's magnetic field, simulating discussion between student and teacher as the equipment is set up and the experiment done. Provides diagrams and illustrative photographs to aid in equipment set-up and measurement. (JM)

Describes a program developed to: increase numbers of physics teachers; provide additional training in physics to teachers who needed it; further stimulate high school teachers; and to serve as resource center. Offers ideas and encouragement to other colleges and universities in rural settings who wish to create such a program. (JM)

Describes a series of writing exercises specifically designed to improve students' comprehension of physics. Students are given a RAFT which defines their role, audience, format, and task. Format for writing essays focuses on key ideas, general ideas, specific cases, and additional insights. (JM)

Describes a simplified method of calculating the speeds necessary to cause large relativistic changes and to determine the magnitudes of physical quantities as an object approaches the speed of light. Provides equations and two completed example problems. (JM)

Reviews courseware (Apple II) providing laboratory simulations in atomic physics. Although material is not user-friendly and requires some background, the animations are good representations of electron mass, Thompson e/m, Millikan oil-drop, and mass spectrometer. Recommended for classroom demonstration purposes at high school or introductory…

Discusses the development of the concept of atomicity and some of the many which can be used to establish its validity. Chemical evidence, evidence from crystals, Faraday's law of electrolysis, and Avogadro's number are among the areas which show how the concept originally developed from a purely philosophical idea.
