Describes laboratory procedures, demonstrations, and classroom activities/materials, including chi-square tests on a microcomputer, an integrated biology game, microscope slides of leaf stomata, culturing soil nematodes, technique for watering locust egg-laying tubes, hazards of biological chemicals (such as benzene, benzidene, calchicine,…

Indicates some of the information that may be obtained from a binary solid-liquid phase equilibria experiment and a method to write a computer program that will plot an ideal phase diagram to which the experimental results may be compared. (Author/CP)

Describes an experiment on the simultaneous determination of chromium and magnesium by spectophotometry modified to include the Generalized Standard Addition Method computer program, a multivariate calibration method that provides optimal multicomponent analysis in the presence of interference and matrix effects. Provides instructions for…

Describes a computer model kinetic theory experiment for the college physical chemistry laboratory. (HM)

A simple analog computer program is described which, in conjunction with a dual-trace storage oscilloscope, can demonstrate travelling and standing waves, the effect of various reflection coefficients, standing wave ratios, and other wave phenomena. (Author/CP)

Describes programs that have been developed to allow kinetic experiments to be simulated on a small computer. Reports the principles that have guided the conception of the programs and describes an instance of their application to a complex reaction. (Author/GS)

Describes computer measurement of capacitor charge decay, change of fringe width with color, computer simulation of color mixing, Doppler effect/carrier waves, gravitational waves, microwave apparatus, computer simulation of Brownian motion, search coils and problems with the teaching of the relationships of velocity, frequency, and wavelength in…

Discusses the Rugby clock as a source of project material, use of ZX81 for experimental science, computer dice analog, oil recovery from reservoirs, and computer simulation of Thompson's experiment for determining e/m for an electron. Activities/procedures are provided when applicable. Also presents questions (and answers) related to time-coded…
