Describes a project which consists of BASIC programs, teacher's guide, and student's notes on six topics for high school biology, chemistry, and physics. Outlines the supply of physics equipment in high schools in three Australian states and presents a procedure for demonstrating small scale temperature inversion in the classroom. (GS)

Examines present and future applications of computers in high-energy physics. Areas considered include high-energy physics laboratories, accelerators, detectors, networking, off-line analysis, software guidelines, event sizes and volumes, graphics applications, event simulation, theoretical studies, and future trends.

Describes a simple apparatus and provides instructions to do relative index of refraction measurements/calculations and to show mathematical relationships betwen indices when light travels from one liquid to another. A listing of a computer program (in BASIC) which will analyze data is available from the author. (JM)

Describes: (1) an apparatus which provides a simple method for measuring Stefan's constant; (2) a simple phase shifting circuit; (3) a radioactive decay computer program (for ZX81); and (4) phase difference between transformer voltages. (Author/JN)

Describes apparatus, computer program (for Apple II), and procedures used in an experiment to determine the velocity of sound in air. In addition, the experiment focuses on the attention required in calibrating equipment and the measuring of both long distances and very short time intervals. (JN)
