Explains how computer and game port interfacing reduces the time required for data collection and organization and also stimulates student interest in science laboratory exercises. Illustrates this approach through a description of a population-variation lab. Includes diagrams for the construction of the interface box. (ML)

Describes the use of a precalibrated stainless steel thermistor, interfaced with an Apple computer, in chemistry experiments. Discusses the advantages of "instant" temperature readings in experiments requiring that readings be taken at certain intervals. Outlines such an experiment which investigates freezing point depressions. (TW)

Explains how a computer uses its vision to determine the area, edge length, width, height, and center of mass in two dimensions from photos of backlit sea shells. Includes HyperCard codes used to instruct the computer to make the calculations. (MDH)
