Describes a compact solar camera built as a one-semester student project. This camera is used for taking pictures of the sun and moon and for direct observation of the image of the sun on a screen. (Author/HM)

Discusses how, through a series of sample problems and solutions, the notion of force as momentum flow can serve as the basis for vastly expanding the importance of Newton's third law as experienced by students in elementary mechanics courses. (Author/HM)

Discusses what is meant by a linear program and states and illustrates two of the theorems upon which the methods of linear programing rest. This description is intended as an introduction to linear programing of physics students. (HM)

Discusses how Volta's concept of electromotive force seems to be forgotten. A comparison of the concepts of potential difference and electromotive force is also included. (HM)

Presents evidence to support the author's viewpoint that Einstein's General Relativity Theory is related to concepts of chemo-electricity. (CS)

Describes layouts for converting a high-top van into a multipurpose laboratory and transport for a college biological sciences department. (CS)

Presents excerpts from a teacher's manual which describes laboratory activities in genetics for advanced secondary school biology students. Maximized are the pedagogical aspects in choosing activities, arriving at intermediate decision-points, and planning the evaluation of pupil achievement. (CS)

The detachable magazine segment is a guide to sources of solar energy information sources. Included are (1) organizations; (2) bibliographies; (3) educational materials; (4) audiovisuals; (5) analytical tools; (6) construction plows; (7) directories and catalogues; and (8) miscellaneous. (Author/RE)

This column notes some recent films, filmstrips, instructional television programs, and free pamphlets that may motivate students toward healthy living, allay fears of illness, and clarify needed facts. (Author)

Provides a viewpoint regarding the failure in engineering education to realize the most fundamental goals of liberal studies. These authors develop the theme of "transcendental engineering," a conception that bridges the gap between theoretical disciplines of the liberal arts college and practical studies of the engineering schools. (CS)

Two problem-solving posters with a Halloween theme are included. These activity sheets are designed to be easily reproduced for classroom use. (MP)

Discusses rapid, approximate methods for the calculation of errors estimates and other statistical results without using the computer. (SK)

Several activities designed to help elementary level students learn how to read calendars are presented. Problem solving and experiential learning are stressed. (MP)

A special calendar chart is presented that can be used to find out what day of the week any date falls on during the 1980s. (MP)

The resources listed different types of materials related to the aerospace science under specified categories: free materials and inexpensive, selected government publication, audiovisual (government, nongovernment), aviation books, and space books. The list includes the publisher's name and the price for each publication. (SK)
