Addresses the introduction of low cost equipment into high school and college physical science classes. Examines the properties of an "ideal" operational amplifier and discusses how it might be used under saturated and non-saturated conditions. Notes the action of a "real" operational amplifier. (TW)

Presents quantitative data on the demand and supply of science teachers in Great Britain, discussing implications for the recruitment and professional training of new teachers. Assumptions made about inactive teachers who return to the teaching profession are also considered. (DH)

Discusses: (1) Brewster's angle in the elementary laboratory; (2) color mixing by computer; (3) computer iteration at A-level; (4) a simple probe for pressure measurement; (5) the measurement of distance using a laser; and (6) an activity on Archimede's principle. (JN)

Presents procedures, demonstrations, activities, and teaching suggestions on topics appropriate for middle school science including a simple electrolysis cell, conversion factors, energy, solubilities of salts, condensers, and a worksheet for studying coppice woodlands. (DC)

Reviews research studies that investigated the relationship between attitude and achievement. Concludes that in general and for science the relationship is weak, indicating that science teachers should focus directly on improving achievement and not on improving attitudes towards science as a means of improving achievement. (DC)

Discusses determination of elliptical path of a satellite caught into orbit by the sun or earth; using microcomputer as signal generator (includes program listing); collision process; simple hysteresis loop using double beam CRO; method of demonstrating parallelogram of forces; measuring radius of electron beam curvature; and half-life of thorium…

Describes laboratory procedures, demonstrations, and classroom materials, including "diet poker" (nutrition game); an experiment on enzyme characteristics; demonstrations of yeast anaerobic respiration and color preference in Calliphora larvae; method to extract eugenol from clove oil to show antibiotic properties; and Benedict's test.…

Summarizes two research studies on: (1) suitability of science reading materials at CSE and O levels, and (2) effects of single sex and coeducation on science subject (N=1200) preferences and choices at 14+. Discusses spider diagrams, what is science, and problems and solutions in chemistry teaching in post-16 institutions. (DS)

Discusses dice model of exponential radionuclide decay; glancing and collinear perfectly elastic collisions; digital capacitance meter; use of top pan balance in physics; microcomputer calculation of gradient of straight line (includes complete Commodore PET computer program); Fresnel lenses; low-voltage radiant heater; Wheatssone's bridge used as…

Summarizes scientific findings resulting from the Apollo missions, including lunar rocks and soil, age determination, and the moon's interior, evolution, and origin. Indicates experiments for future lunar research. (SK)

Describes the use and handling of alkali metals in school laboratories and seeks to reexamine precautions which one may reasonably take before executing routine procedures since their use, even by skillful teachers, occasionally results in accidents in the form of violent explosions. (Author/SK)

Describes three case studies presented in a British science course to show the impact of industrial chemicals on people's lives, and how students can evaluate various factors involved in a particular case study. References and a list of factors for each case study are also included. (HM)

Describes a project sponsored by the Association for Science Education (ASE) that has proved successful and is now known as Science across the World. This project aims at linking schools in all parts of the globe. Describes how Science across the World works and reports on the evaluation of its use. (DDR)

Described is the use of the Bible as a source of information on the availability and use of metals in ancient societies. The use of the Bible in cross-curricular work between science, technology, and religious studies is discussed. (Author/CW)

Information technology will be an important influence in education in the future. This article discusses the use of instructional technology for science teaching and considers the impact of technology on what is taught and how science is taught. (Author/CW)
