Described are the apparatus and procedures needed for a demonstration of the measurement of the electrical resistance of metals as a function of temperature using a microcomputer interface. Discussed are materials, apparatus construction, and experimental results. (CW)

This paper describes how computers were employed by workshop participants, the commercial materials used, some of the experiments performed using computer interfaces, and the effect of computer interfacing on the science laboratory. Increased student interest through the study of open-ended experiments is discussed. (CW)
