Kauffman, George B. – Journal of College Science Teaching, 1985
Part I (SE 537 587) briefly reviewed the scientific discoveries underlying the atomic bomb and its technological development. This part examines the implications of these events for science education. Areas considered include the nuclear arms race, nuclear winter, the Strategic Defense Initiative, and others. (DH)

Kauffman, George B.; Ebner, Ronald D. – Journal of College Science Teaching, 1985
Describes a demonstration in which gaseous ammonia and hydrochloric acid are used to illustrate rates of diffusion (Graham's Law). Simple equipment needed for the demonstration include a long tube, rubber stoppes, and cotton. Two related demonstrations are also explained. (DH)

Kauffman, George B.; And Others – Journal of College Science Teaching, 1986
The use of sodium acetate solution to show supersaturation is a favorite among lecture demonstrations. However, careful adjustment of the solute-to-water ratio must be made to attain the most spectacular effect--complete solidification of the solution. Procedures to accomplish this are provided and discussed. (JN)

Kauffman, George B. – Journal of College Science Teaching, 1997
Describes an outdoor scientific demonstration of metal reduction, a reaction known as the thermit process. Heat from an ignition mixture is required to initiate the reaction, which then becomes self-sustaining. The demonstration provides a dazzling introduction to such fundamental general chemistry topics as oxidation-reduction, metallurgy,…
