Describes: (1) a microcomputer demonstration of autocatalysis; (2) a safe alternative to ethanol and methanol; (3) a simple condenser for test-tube reactions; (4) a new procedure for studying the magnetic properties of transition metal compounds; (5) plasticization of the polymer PVC; and (6) some thoughts on polybasic acids and their salts. (JN)

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)

Proposes the V-Scope as a teaching aid to measure, analyze, and display three-dimensional multibody motion. Describes experiment setup considerations, how measurements are calculated, graphic representation capabilities, and modes of operation of this microcomputer-based system. (MDH)

Describes the functioning of temperature transducers, or thermistors. Discusses the interface connections between thermistors and the game-port of several kinds of microcomputers. Demonstrates how to construct a thermistor probe and suggests several applications of the use of such probes in various scientific experiments. (TW)

Discusses the use of two different computer applications to teaching college chemistry. Describes the "electric laboratory notebook" (ELN) courseware and its use in an instrumental analysis course. Provides an overview of the use of commercial spreadsheet programs in the chemistry laboratory. (TW)

Discusses various types of transducers and explains the use of a photoresistor in sensing light. Describes various hardware and software combinations which can be used with photoresistors in science laboratory experiments. Presents general applications of this instrument in light-meter, solarimeter, and colorimeter experiments. (TW)
