Points out that the effectiveness of microcomputer-based laboratory (MBL) activities will be examined. Also indicates that a study is being conducted to assess children's and college students' mental models of heat and temperature and to determine how these models change when students learn about heat through MBLs.

Bank Street Laboratory (a set of hardware/software tools for measuring temperature, light, and sound) consists of a board that plugs into Apple microcomputers, cabling, software, and six probes. Discusses the laboratory's hardware, including the analog-to-digital converter, multiplier chip, and modular connectors. Circuit diagrams of components…

Describes "Experiments in Chemistry," in which experiments are performed using software and hardware interfaced to the Apple microcomputer's game paddle port. Experiments include temperature, pH electrode, and EMF (cell potential determinations, oxidation-reduction titrations, and precipitation titrations) investigations. (JN)
