The author discusses a system for establishing the relative potential of a chemical to release energy suddenly and to indicate release. This system is applicable to chemical storage and transportation. The system is based upon three simple tests requiring a minimum sample (1 go or 1 ml): (1) computation, (2) impact sensitivity, and (3) thermal…

Short articles on the kinetics of the hydrogen peroxide-iodide ion reaction, simulation of fluidization catalysis, the use of Newman projection diagrams to represent steric relationships in organic chemistry, the use of synthetic substrates for proteolytic enzyme reactions, and two simple clock reactions"--hydrolysis of halogenoalkanes and…

Describes modifications of laboratory procedures for the BSCS Green Version biology, including dissection, microbiology, animal behavior, physiology, biochemistry, and genetics that make the methods suitable for direct experimentation by blind students. Discusses models as substitutes for microscopy. (AL)

A study was conducted to assess attitudes and achievement in physics of college freshmen. Interest in college physics has dropped significantly. Other findings about Physical Science Study Committee attitudes of boys versus girls and student achievement are significant points for future consideration. (PS)

Recognizes that physics, like other sciences, deals with information in the form of sense impressions. Concepts of mass length and time are not sensory experiences and should substitute instead the terms of force, displacement and time for better understanding. (PS)

Argues that the theologic way of knowing represents a distinctly different and incommensurable process of developing knowledge from that of the natural sciences (and that) 'creation theory' is not an alternative scientific theory to the Neodarwinian theory of evolution" and has no place in a science curriculum, although it may be introduced as…

The results of surveys to determine student reactions to the difficulty of various topics in the Scottish syllabi in secondary school chemistry are summarized. The surveys were given to O-grade (average ability), H-grade (high ability), and Sixth-Year (optional, advanced) students. (TS)

At grades 10 and 12 in high school, and in the universities, a science cognitive style was identified. Students with a high science orientation are characterized by high conceptual differentiation; high categorizing flexibility with objects; high preference for analytic-descriptive concepts; high originality; low preference for…
