Described is how to build a solar furnace model. A detailed list of materials and methods are included along with diagrams. This particular activity is part of an audiotutorial unit concerned with the energy crisis and energy alternatives. (MA)

A high school class, housed in a temporary prefabricated structure, designed and built a solar energy element to heat the building. (JD)

Solar energy collector panels are used as a freestanding canopy over walks that will connect an arts complex eventually consisting of five buildings. (Author/MLF)

Evaluates how well the media guided readers and viewers through the Chernobyl disaster. Concludes that the press and television did not provide enough radiation and risk information in their coverage of the Chernobyl accident, but what was provided was appropriate, even-handed, and conservative. (NKA)

Described are the natural trace radionuclides in ground water. Indicates the geologic origin of these radionuclides. Discusses the importance of these radionuclides. Suggests future uses of a number of additional radionuclides. (CW)

Buildings can be designed in harmony with the natural environment, and new techniques of "active" solar design exist to collect and use solar energy for space heating and cooling. Preservation and reuse of existing buildings and neighborhoods are other ways to conserve energy. (Author/MLF)

Speaks to the role of vocational education in providing massive training programs to prepare technicians and other service personnel to perform installation and service functions necessary to support architects and engineers designing and developing solar energy systems. (HD)

Discusses solar thermal collectors, solar thermal electric power conversion, photovoltaic power conversion, and wind energy conversion, and discusses implications for industrial arts. (TA)

Outlines the discovery and nature of ultraviolet light, discusses some applications for these wavelengths, and describes a number of experiments with ultraviolet radiation suitable for secondary school science classes. (JR)

Describes the main features of four experimental solar heating plans to be installed in four different schools in Maryland, Massachusetts, Minnesota, and Virginia. (Author/DN)

To improve the general environment, the author stresses the need to preserve and protect our natural resources of water, air, and food. The problems of population growth, radiation hazards, pesticides, noise pollution, and waste disposal are also discussed. Bibliographies. (LC)

This study objects to the "very specious statistical arguments" of Ernest Sternglass and Steven Bell in the April issue of this magazine, in which illogical and inconsistent statistical evidence suggested cognitive damage during infancy may be linked to atmospheric testing of nuclear weapons from 1954 to 1963. (PB)

Presents an experimental comparison of the efficacy of two neutron sources under conditions commonly used in laboratory experiments for demonstrating neutron activation of liquid samples. (Author)

Background information, materials/procedures, and results are provided for an undergraduate laboratory experiment on a photochemical ligand substitution reaction using sunlight. The experiment illustrates demonstration of photochemistry and basic mechanisms of transition metal reactions using inexpensive materials and is easily followed by…
