Discusses a six-week course in urban problem solving conducted by Newark College Engineering for high ability inner-city students in the summer of 1971 and 1972. Indicates that the experiment in mixing urban laboratories, city problems, and high school juniors is an educational success. (CC)

An attempt to stimulate interest in solar study is made by discussing how it could fit into a physics curriculum and by describing an effective installation already in use. (DF)

A series of activities for preservice teachers has been designed to illustrate differences and similarities in new curricular developments. (RH)

Discusses use of two EAI semi-expanded TR-20 units to display solutions to differential equations for harmonic oscillators, quantum-mechanical particles, trajectories, radioactive decay series, and hysteresis curves. Suggests practical applications for both undergraduate physics laboratories and classroom demonstrations. (CC)

Discusses the fundamentals of two personnel dosimeters: the lithium fluoride thermoluminescent dosimeter and the silver-activated phosphate glass radiophotoluminescent dosimeter, and indicates the usefulness of this presentation for both teachers and students. (CC)

Outlines experiments in which a density gradient might be used to advantage. A density gradient consists of a column of liquid, the composition and density of which varies along its length. The procedure can be used in analysis of solutions and mixtures and in density measures of solids. (Author/TS)

Describes a one-month summer program at Rutgers University for 23 inservice inner city elementary school teachers from ten New Jersey school systems. Program objectives include development of a model for sciences and mathematics education in urban environments; teacher experience with developing instructional materials; and trial use of the model…
