Background information, lists of materials needed, and procedures are provided for 12 experiments which focus on various aspects of pollution and the environment. Topics considered in the investigations are: (1) solids in the air; (2) effect of air pollution on nylon; (3) measuring lung capacity; (4) an electrical smoke trap; (5) photosynthesis;…

This document presents a secondary level physics unit which introduces students to the Wheatstone Bridge, its use in determining the value of unknown resistors, and the effects of wiring resistors in series or in parallel. (SL)

Presented is a secondary level physics unit which introduces students to electrical resistance in series and parallel combinations, use of the voltmeter and ammeter, wiring simple circuits, and writing scientific reports. (SL)

Describes a low priced ripple tank with accessories for use with an overhead projector as well as the assembly of a variable speed wave source. Photographs are included. (GH)

Introductory science has become a discovery course for the students at Phillips Exeter Academy (New Hampshire), who are above average in ability and motivation. The philosophy of the course is that it should serve a more humanizing function than the preparation of young technicians, and that this function is as important for the future scientist…

An experimental solar heating system heats five modular classrooms at the Fauquier County High School in Warrenton, Virginia. The present report covers the operation, maintenance, and modifications to the system over the 1974-75 and 1975-76 heating seasons. The solar system has shown the capability of providing essentially 100 percent of the…

In the Skylab student project, high school students submitted proposals for experiments that could be performed on board Skylab by the astronauts. This book describes the experiments designed by the students and reports what happened to those experiments in the space laboratory. The student experiments included studies of the central nervous…

This anthology of articles and speeches by associates of the Contemporary Music Project traces the development of the theory of comprehensive musicianship during the first ten years (1959-1969) of the Project activities, providing a history of the program. Part I details the initial music education program--the Young Composers Project through…

This vocational physics individualized student instructional module on thermometers consists of the three units: Temperature and heat, expansion thermometers, and electrical thermometers. Designed with a laboratory orientation, experiments are included on linear expansion; making a bimetallic thermometer, a liquid-in-gas thermometer, and a gas…

Indicates how the gas laws can be derived and taught to high school and college physical science classes by using the guided-discovery method. (LS)

Presents a list of Biology-A level projects submitted for the Oxford and Cambridge Board examination by pupils of Uppingham School in the United Kingdom. (HM)

Discusses the range of wavelengths of the electromagnetic spectrum considered to be the visible portion. Describes a demonstration designed to help students understand the relation between the wavelength measurements on a spectrophotometer such as the Spectronic 20 and the actual colors of light being used. (TW)

Describes a technique of impregnating small amounts of sandy sediment in a quick curing resin for microscopic examination. Details the preparation of materials. Suggests laboratory exercises based on this preparation. (CW)

Discusses combustion by suggesting several experiments and demonstrations using matches. Integrates quotes from famous scientists about the various phenomenon regarding combustion. (TW)

Describes the Interactive Microcomputer Peripheral (including major features, source, and current cost) and physics experiments using the instrument. The instrument can also be used for such purposes as counting, timing, and frequency measurement as well as for experiments in biology and experimental psychology. (JN)
