Describes the operation of a processing center for the construction and maintenance of Elementary Science Study (ESS) kits in an economically depressed county of Virginia. This small industry provides an important function in the community by creating jobs and by producing school science equipment more cheaply than commercial enterprises. (JR)

Describes the natural habitat, life-history, and behavior of gerbils. These animals do not drink water, are virtually odorless, can withstand wide temperature ranges, and require minimal attention. As a result they have become popular in research and science classrooms in recent years. (JR)

Discusses the origin of life on the basis of information about cosmic evolution, stellar alchemy, atmospheric histories, and rise and fall of civilizations. Indicates that man's contact with other civilizations in our galaxy may be made possible through studies of interstellar communication. (CC)

Discusses two sampling methods used to evaluate ambient air: the bubbler technique and the use of static samplers. Indicates that vegetation is also excellent indicator of air pollution effects. (CC)

Discusses the life and work of Copernicus and his impact on the development of the scientific enterprise. Concludes that his treatise provides some indications of the nature of science and of the scientific mind in the centuries to follow. (CC)

Discusses formation of chemical molecules via Mobius strip intermediates, and concludes that many special physics-chemical properties of the fully closed circular form (1) of polyoma DNA are explainable by this topological feature. (CC)

Describes author's use of a three foot long tube, open at both ends, to exemplify that his highest falsetto note is lower than his lowest whistled note. (CC)

A method of disposal is suggested that is superior to the dilution method. The proceudres are based on the conversion of the wastes to less toxic or harmless forms or neutralization, so that they won't be a shock to the sewage system, and then excess dilution. (Author/DF)
