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)

As a continuation of SE 516 125 (The Powered Phase), this report provides a detailed analysis of the coast phase of a model rocket trajectory. (CP)

Defines 13 concepts involved in understanding ionic equations and suggests the order in which they should be taught. Also analyzes incorrect responses on an ionic equations student exam. (MLH)

Discusses reasons why chemistry should be taught at the secondary level, its function in the general education of citizens, and the contribution to teaching skills such as observation and inference. (MLH)

Discusses the present hierarchy of chemical education levels in Great Britain and proposed changes to this structure. (MLH)

The history and definition of pH is presented along with sample calculations. (BB)

Aspects of textbooks' readability are discussed and some recommendations are made. The results of applying three readability tests to 13 current textbooks are presented. (Author/BB)

Discusses some high school physics demonstrations and experiments on a variety of topics: such as uses of the dipole, the vapour-liquid critical point, velocity of sound in metallic rods, the flux-density near a bar magnet, and a different style logic gate using basic units. (GA)

Lists several ideas for experiments for the amateur scientist to try or design. The list covers a wide range of topics; sound, mechanics, thermodynamics, fluids, optics, and electrostatics. (GA)

The data show that biology teachers spend relatively little time on diseases of the cardiovascular system. Approximately one period per year is spent on each of eight given cardiovascular disease risk factors. (MP)
