Discusses basic concepts for environmental education in elementary schools. Materials and activities are viewed in relation to instructional purposes and child development. Emphasis is placed on procedures with urban children. (JM)

Discusses the proposition that science is a method for the description, creation, and understanding of human experience, and as such, should be taught in a unified approach in secondary schools and in general education courses at the college level. A science program using the unified approach is presented, and its merits and demerits are…

Discusses the concept energy" in terms of its use as a unifying theme in secondary school science courses. (AL)

...the main functions of certain texts are set out here, and these provide some definite objective in the teaching of structures for the teacher of English who has to deal with technical students." Part 1 appeared in English Language Teaching" v24 n2 p120-124, January 1970. (FB)

Discusses the use of games for teaching introductory physics. The elements of game design are reviewed, and sevel examples are described that illustrate different varieties of teaching games suitable for use by beginning physics students. Bibliography. (LC)

Discusses reasons why the original van Deemter equation should no longer be taught and why three other equations, better representing chromatographic dispersion, are preferred. Also discusses underlying phenomena in terms that can be transmitted to sophomores. (JN)

Photoelectrochemistry is based on the semiconductor electrode. It is the semiconductor's ability to absorb light and convert it to electrical and/or chemical energy that forms the basis for the semiconductor liquid-junction solar cell. To understand how this occurs, solid-state physics concepts are discussed. (Author/JN)

The use of semiconductors as electrodes for electrochemistry requires an understanding of both solid-state physics and electrochemistry, since phenomena associated with both disciplines are seen in semiconductor/electrolyte systems. The interfacial energetics of these systems are discussed. (JN)

Describes five physics demonstrations using inexpensive and easily obtainable materials. Demonstrations include: (1) sinking ice cubes and diffusion; (2) returnable can; (3) persistent currents in a liquid; (4) light scattering by milk particles; and (5) rotation of a plane of polarization. (JN)

Gender differences in predicting displaced volume did not reflect gender differences in spatial ability, field-dependence-independence, or Piagetian formal reasoning. In addition, gender differences were not accounted for by science and math course-taking experience. (Author/PN)
