Describes the building and testing of a robust pressure sensor suitable for use in schools that produces an output that can be fed into a standard computer interfacing set. (Author/NB)

Describes a simple computer-interfaced experiment for recording the response of an RC network to direct current and square input signals. Undertakes a systematic qualitative and quantitative analysis for the high- and low-pass configurations. Suggests some examples of open-ended problems to develop a feel for circuit behavior. (AIM)

Introduces three physics experiments for high school and college classes. Topics include measuring the ratio of heat capacities using a microcomputer and a glass syringe, producing large electric sparks using a variation of a Leyden bucket, and observing transmission line behavior using television signals. Includes descriptions of materials and…
