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…

Explores several options and advantages of using microcomputers in science teaching. Describes programs for calculating pH, Maxwell-Boltzman distribution of velocities in a gas, atomic orbitals, and lattice energies. Also suggests use of microcomputers in the areas of simulations, scoring tests, and controlling stock. (DS)

Outlines a variety of laboratory procedures, demonstrations, and classroom materials including a technique for estimating speed of electromagnetic waves; a support for multipin components when soldering; use of dynometer to measure force; bending light; using a microcomputer to measure and produce voltage; force-distance curves; and two games.
