Summarizes the effects of arsenic, lead, zinc, mercury, and cadmium on human health, indicates the sources of the elements in water, and considers the possibility of students in high schools analyzing water for trace amounts of the elements. (AL)

Many benefits from aerospace research have occurred: research on quiet aircraft engines, worldwide news coverage, contributions to the national economy, development of reliable fluid amplifiers and logic systems, attempts to control airport congestion, a low speed air sensor for use on a pulmonary flow meter and even as a flow meter in a large…

Photographs of the earth taken from space are used to illustrate the advantages and application of remote sensing. This technique may be used in such areas as the immediate appraisal of disasters, surveillance of the oceans, monitoring of land, food and water resources, detection of natural resources, and identification of pollution. (JR)

State geological surveys offer a wealth of information and aid for teachers. Suggestions for contacting state agents, using their materials, finding other resources, developing class activities, and conducting field trips are included along with a plan for a geological jaunt from Mississippi to Minnesota. (DH)

A stock notation for naming chemical compounds, eliminating suffixes and adding a Roman numeral to indicate oxidation number is suggested. (CP)

The use of cybernetics is shown to be a tool for bringing together various scientific fields and the social sciences via logic. Topics are discussed with application to help science teachers employ scientific knowledge and technical tools to build a truly civilized world of abundance.'' (DF)

Provides historical description of how the universe began and includes its present status, with implications for the future. (DF)

Recent manned and unmanned space probes have detected hydrogen geocorona and airglow emission bands on the night side of the earth, formed by interplanetary materials. (DF)

The Mariner 9 mission has shown that surface changes, thought previously to be a by-product of some form of life, are intimately connected to strong Martian winds which scour the surface. Close-up photographs of the two moons dispel the notion that they are artificial satellites. (DF)

Objects and energy sources are detected whose existence was only hinted at a few years ago. The X-Ray sky has a large number of sources along the Milky Way, most of which lie within 30 degrees of the galactic center, plus a number of faint sources associated with external galaxies. (DF)

The space shuttle, which will be developed for space transportation in the 1980's, will make space flight simple, less time consuming, and less expensive. (DF)
