Describes a program which simulates the kinetic behavior of a "typical" enzyme. Program objectives, background to the kinetic model used in the simulation, major program features, typical results obtained, and a note on the availability of the program (written in BASIC for Commodore microcomputer) are included.

Describes computer measurement of capacitor charge decay, change of fringe width with color, computer simulation of color mixing, Doppler effect/carrier waves, gravitational waves, microwave apparatus, computer simulation of Brownian motion, search coils and problems with the teaching of the relationships of velocity, frequency, and wavelength in…

Presents an experiment which links mass spectrometry to gas chromatography. Also presents a simulation of iron extraction using a ZX81 computer and discussions of Fehling versus Benedict's solutions, transition metal ammine complexes, electrochemical and other chemical series, and a simple model of dynamic equilibria.
