Describes a method for making a simple, inexpensive apparatus which can be used to determine Planck's constant. Provides illustrations of a circuit diagram using one or more light-emitting diodes and a BASIC computer program for simplifying calculations. (RT)

Emphasis on interfacing -- the various processes for passing information into or out of computers -- is suggested. Why the Texas Instruments microcomputer is plausible for this is noted, followed by specific interfacing suggestions, including programs for a timer and the assembly language subroutine. (MNS)

Describes the New Jersey Chemistry Olympics involving events such as library research, laboratory experimentation, model building, and computer programing. The goals, operational plan, competition events, and evaluation of the Olympics are discussed. (YP)

Offers a rationale and method for using the hand controllers (game paddles) in the design of computer programs for student use. Methods for their use in entering data as well as in conducting pendulum and acceleration experiments are provided. Complete program listings (for Apple) are included. (JN)
