Describes a software/hardware system for running computer-controlled physics experiments. Each set of experiments consists of a disk (for Apple 48K), instruction manual, and student manual. The pendulum and acceleration experiments are described. Although not described, experiments using a temperature probe are also available. (JN)

Provided is a review of a high school/college level computer program (for Apple microcomputers) which consists of six simulations designed to introduce students to simple harmonic motion. Includes a discussion of the six simulations and such information as time needed, probable classroom use, source, and current cost. (JM)

Discusses Heisenberg's uncertainty principle in simple terms. Presents scientific examples leading to the development of the principle and describes popular misconceptions associated with it. (SK)

Describes a procedure for determining the coefficient of restitution using a microcomputer which collects and sends data to a large computer where analysis is done and graphical output is generated. The data collection hardware and software are described, and results are illustrated. (Author/SK)

Studies the effect of V-Scope activities on the performance of 11th-grade students in analyzing kinematics graphs. Students were challenged to construct different kinds of graphs using their own movements as well as the motion of a dynamics cart. Results indicate that the V-Scope kinematics laboratory activities can promote kinematics concepts and…

Directions for the construction of this apparatus are presented. Materials and procedures for its use are discussed. The behavior of particles in the apparatus is described. (CW)

Presented are nine physics demonstrations. Topics include mechanics, magnetism, mass, optics, friction, and molecular motion. An illustration and questions are included for each. (CW)

The question of how children solve force and motion problems in computer simulations without explicit knowledge of the underlying physics was investigated. Keystroke sequences made by children were saved and analyzed, and children were interviewed to understand their perception of the relationship between keyboard input and on-screen action. (CW)

Investigates whether elementary children can compare forces by comparing numbers of weights used in spring and balance problems. Reports that children did not identify weight and force, but they were able to use the ratio between the numbers of weights to compare forces. Suggests some instructional methods based on the findings. (YP)

Reports experiences during a two-year period in introducing the computer to the laboratory and students to the computer as a laboratory instrument. Describes a working philosophy, data acquisition system, and experiments. Summarizes the laboratory procedures of nine experiments, covering mechanics, heat, electromagnetism, and optics. (YP)

Provides a reading list for A- and S-level biology. Contains several experiments and demonstrations with topics on: the intestine, bullock corneal cells, valences, the science of tea, automated hydrolysis, electronics characteristics, bromine diffusion, enthalpy of vaporization determination, thermometers, pendulums, hovercraft, Bernoulli fluid…

Reviews the problem of certain logical and conceptual shortcomings in textbook presentations of the energy concepts in introductory physics. Discusses concepts and principles related to thermodynamics and echanics. Provides many formulas and diagrams. (YP)

Models which demonstrate the concept of moment of force in two- and three-dimensional cases and have been well received by students are described. Photographs and instructions for each model are provided. (MVL)

Reports the design of the "Mechanics Baseline Test," an instrument to assess students' understandings about concepts in mechanics. Discusses how comparisons of test results with extensive baseline data can be used to evaluate instruction at all levels. Includes a copy of the instrument. (MDH)

Discusses the emergence of chaos as a major scientific subject and its place in historical, scientific, and technological context. Three sections provide (1) an overview of the scientific paradigm; (2) a review of the ideology of classical mechanics; and (3) examples of classical systems behaving in peculiar, nonintuitive manners.
