Actin and myosin have now been demonstrated to be important constituents of many eukaryotic cells. Their role is primarily that of a contractile system underlying all aspects of cellular motility. Described here is a simple experimental system to demonstrate quantitatively aspects of motility and its regulation in a slime mold. (Author/MA)

Describes an experiment wherein simple gamma-ray detection and analysis techniques were utilized to study radioactivity in local precipitation. (Author/SL)

An experiment on the heat conductivity of different materials are described. Applications for energy education in the elementary classroom are implied. (MDR)

Presents an apparatus for demonstrating two-dimensional random motion suitable for illustrating molecular phenomena. Three specific uses are presented. (SL)

Describes an experiment for estimating the half-life of thorium-232. (SL)

Sticks, string and observation start children off on the bare bones of human biology. (Editor)
