Basic knowledge about Skylab experiments is presented in this book, one of a series, for the purpose of informing high school teachers about scientific research performed in orbit and enabling the teachers to broaden their basis for material selection. This fourth volume is concerned with experiments designed to improve man's understanding of…

The purpose of this study was to assess the effectiveness of Elementary Science Study (ESS) materials for developing creativity in children. Three hypotheses were formulated to the effect that children who receive ESS instruction will achieve higher scores on Torrance Tests of Creative Thinking (TTCT) Figural and Verbal, and on the investigator's…

This eleventh edition of the Educators Guide to Free Science Materials is devoted exclusively to free science materials, based on the cross-media approach. It is designed to provide a continuing means of identifying existing materials that are currently available. It is a complete, up-to-date, annotated schedule of selected free or inexpensive…

Presented are the proceedings of the first international Congress on "Space for Mankind's Benefit" organized by the Huntsville Association of Technical Societies and held November 15-19, 1971, at Huntsville, Alabama. Following introductory statements, a total of 45 articles read in 10 sessions are incorporated. The session headings are:…

Reviews the history of selected topics in organic chemistry, including organic synthesis, free-radicals, and instrumentation. (MLH)

This is one of a series of resource letters on different topics intended to guide college physicists, astronomers, and other scientists to some of the literature and other teaching aids that may help improve course content in specified fields. (Author/CP)

Explains how reading aloud to secondary school students in science classes is beneficial and that it helps them comprehend written scientific materials. (GA)

A discussion of problems students have with the concept of percent, with special emphasis on the use of percent in elementary chemistry. (BB)

Discusses the principle of nonisothermal kinetics and some of the factors involved in such reactions, especially when considering the reliability of the kinetic parameters, compared to those of isothermal conditions. (GA)

Energy eigenstates are superimposed in order to form a wave packet for an electron propagating in one dimension under the influence of a uniform, time-dependent electric field. A graphical method is presented by which one can obtain both the position and shape of the envelope. (BB)

A complete matrix formulation of the theory of small oscillations is presented. Simple analytic solutions involving matrix functions are found which clearly exhibit the transients, the damping factors, the Breit-Wigner form for resonances, etc. (BB)

Reviews concepts involved in the ideas of curved space and a closed universe in the general theory of relativity. (SL)
