A study describes an easy procedure based on a negative photoresist process designed for junior high or high school students, which will introduce them to the key terms and concepts of photolithography. The experiment allows students to visualize the fundamental process behind microchip fabrication, observe the rapid prototyping enabled by such a…

Advocating that Canadian art programs should use and model environmentally safe practices, the articles in this journal focus on issues of safe practices in art education. Articles are: (1) "What is WHMIS?"; (2) "Safety Precautions for Specific Art Processes"; (3) "Toxic Substances"; (4) "Using Clay, Glazes, and…

Science In a Social CONtext is a series of eight books based on the project SISCON-in-Schools. The books provide a new course in science and society for general studies at sixth-form level. The course has been specially designed to make scientific problems accessible to the non-scientist, as well as to explain the social aspects of science to the…

Factors concerning water distribution systems, including an evaluation of materials and a recommendation of materials best suited for service in typical facilities are discussed. Several installations are discussed in an effort to bring out typical features in selected applications. The following system types are included--(1) industrial…

A project was conducted at Delaware County Community College, Media, Pennsylvania, to train two instructional staff members in the area of composite materials technology. A 1-year training program was set up for the two technical instructional specialists at the Boeing Helicopter Training Center, Eddystone, Pennsylvania. The program consisted of…

Environmental impacts arise from entanglement of marine animals in plastic debris and from ingestion of plastics by marine organisms. Plastic debris can cause potential threats to humans when divers become entangled or vessels become fouled in debris. The depletion of fishery resources, vessel damage, and aesthetic degradation resulting in lost…

This document, one of eight in a multi-cultural competency-based vocational/technical curricula series, is on fiberglass technician. This program covers 12 instructional areas: orientation, safety, introduction to fiberglass-reinforced plastics, hand lay-up, introduction to equipment operation, chopper operation, gel-coat equipment, finish and…

To establish criteria for developing plastics education programs for industrial education which meet the needs of the plastic industry, 163 (81 percent) questionnaires were completed by processors and converters. Trade journals, magazines, textbooks, and other studies in plastics education provided further information. Conclusions drawn from the…

A unit of study suitable for secondary school chemistry classes. (BB)

Details ab initio crystal orbital calculations using all-trans-polyethylene as a model. Describes calculations based on various forms of translational symmetry. Compares these calculations with ab initio molecular orbital calculations discussed in a preceding article. Discusses three major approximations made in the crystal case. (CW)
