Described is the use of computer software, with and without guiding text, for a simulation that presents processes related to electric charges and electric forces underlying the electric-pendulum phenomenon. Included are methods for integrating this simulation with actual middle-school science class demonstration. (JJK)

Explores the application of the microcomputer as an adjunct to laboratory experiments within the science curriculum. Identifies needs and critical competitors that may affect implementation. Indicates problems along with suggestions for improving the effectiveness of this method. (RT)
