These notes describe six practical activities for supplementing standard practical work in radioactivity. They are based on a series of workshops given at ASE regional and national conferences by the ASE's Safeguards in Science Committee. The activities, which demonstrate aspects of radioactivity, feature consumer items that happen to be…

Provides a reading list for A- and S-level biology. Contains several experiments and demonstrations with topics on: the intestine, bullock corneal cells, valences, the science of tea, automated hydrolysis, electronics characteristics, bromine diffusion, enthalpy of vaporization determination, thermometers, pendulums, hovercraft, Bernoulli fluid…

Included is information regarding: fabrication of light emitting diodes, their operation as semiconductors, and an experiment demonstrating electroluminescence; experimenting with Random Access Memory (RAM) circuits; demonstrating Coriolis effect; measuring the diameter of an electron beam, E.H.T. meters; launching a trolley by catapult; a "random…

The three principal commercially published science projects for less able/motivated students include units on electronics. A simple and inexpensive method of constructing electric circuits is described. Suggestions for making the material in the published units applicable to circuits found in everyday situations are offered. (JN)

Presents nine selected physics notes which could be used in selected physics courses. Each includes the name of the author and a description of activities suggested. (HM)

Describes equipment, activities, and experiments useful in physics instruction, including among others, a list of articles relating to physics topics, computer interface that makes a computer cost effective, use of a guitar in vibrating string experiments, and photoelectric aids to the measurement of distance, speed, velocity, and acceleration.…
