Describes and discusses the procedure for a demonstration, found in the CHEMStudy film "Shapes and Polarities of Molecules" and in the Nuffield Advanced Chemistry and Physical Science materials, to qualitatively illustrate the differences between polar and non-polar liquids. (PEB)

Briefly describes films about the following topics: water cycles, the energy crisis, the eruption of Mt. Aetna, the hot springs of Yellowstone National Park, and methods of using pine cones to determine the ages of ancient civilizations. (MLH)

The major purposes of this study were to evaluate the effect of the use of slide/tape units as an instructional aid for the teaching of laboratory technique in the college general chemistry laboratory and to determine if special instruction in creativity would effect creativity in chemistry. The units were evaluated under three conditions of…

Illustrates how various common objects can be used in the classroom to demonstrate physical science concepts. Describes the use of toys, ice cubes, light bulbs, meter sticks, and wine bottles as teaching aids. (MLH)

Describes the use of a device, the "Maxwell Demon Bottle," for demonstrating the meaning of entropy and the grainy nature of matter and energy. (JR)

Sixth graders find out the do-it-yourself way of learning pays off when they construct their own instruments in their study of simple machines. Three machines were constructed. (EB)

A preliminary draft of a "Teacher Training Aid to Help Teachers Understand the Processes of Science" has been prepared on the basis of a careful analysis of the current practice of science. This manuscript attempts to formulate guidelines for an explanation of communicative processes of scientific inquiry to students without rigorous background…
