Reports on technological advancements in the fields of solar collectors, thermal storage systems, and solar heating and cooling systems. Diagrams aid in the understanding of the thermodynamics of the systems. (CP)

Describes studies by L. D. Mackay and P. L. Gardner that were designed to teach attitudinal objectives in the Physical Science Study Committee (PSSC) course. Differences in results are attributed to the effect of socio-economic level, passage of time and reduced teacher enthusiasm, factors extraneous to PSSC, and a slightly different sample. (GS)

Describes an instructional unit and objectives on machine design and principles that centers on student-constructed miniature automobiles. (MLH)

Experimenting with weights in a two-pan balance can be used in a series of activities on application of trigonometry. (SD)

Reports on a survey of Wisconsin high school principals, guidance counselors, and physics teachers concerning their attitudes towards physics in the high school curriculum. Results indicate that a greater effort should be made to inform principals and guidance counselors as to the value of physics in the high school curriculum. (Author/CP)

Reviews some statistics on graduate physics education and discusses some of the problems involved in maintaining high standards. (MLH)

Presents experiments, demonstration, activities and ideas relating to various fields of physics to be used in physics courses in secondary schools. The use of a programable pocket calculator in A-level physics courses is among the activities described. (HM)

Explains a new method of detecting radioactive isotopes by counting their accelerated ions rather than the atoms that decay during the counting period. This method increases the sensitivity by several orders of magnitude, and allows one to find the ages of much older and smaller samples. (GA)

Describes experiments in ice physics that demonstrate the behavior and properties of ice. Show that ice behaves as an ionic conductor in which charge is transferred by the movement of protons, its electrical conductivity is highly temperature-dependent, and its dielectric properties show dramatic variation in the kilohertz range. (Author/GA)

Explains the objectives and the offerings of two honors courses in engineering physics and physics and education at Loughborough University of Technology. (GA)

Assesses the broader aspects of the roles of the physics teacher and the physicist in the Third World, and discusses some of the problems they face in general administration, teaching, and research. (GA)

Describes an experiment designed to measure the forces between charged parallel plates, and determines the relationship among the effective electrode area, the measured capacitance values, and the electrode spacing of a parallel plate capacitor. (GA)

Describes an apparatus which attempts to give a direct visual impression of the random detection of individual photons coupled with the recognition of the classical intensity distribution as a result of fairly high proton statistics. (Author/GA)
