Over 500 chemical educators met at Oklahoma State University during August 1982 to assess the condition of chemical education in the United States. Lists of conference organizers, technical program organizers and/or moderators, plenary speakers, special projects coordinators, ancillary program organizers, contributors, exhibitors, conference…

Thirteen papers presented at the Seventh Biennial Conference on Chemical Education (Stillwater, Oklahoma 1982) are summarized. A variety of chemical topics were addressed, including development of printed circuit boards, chemical/physical structure of hair, brewing, uses of EDTA, cleaning agents, hydrocyanation of olefins, drag reducers, and…

Discusses how the wheel works. The inherent mechanical advantage of wheel-and-axle system is that it reduced the distance the load-bearing surfaces have to slip relative to one another when the whole apparatus advances some given distance reducing (with leverage) the force needed to propel the system. (Author/JN)

Focusing on the centromere (kinetochore), discusses what term should be used to represent this cellular component. Also discusses centromere/kinetochore replication, structure of the kinetochore, and the nature of the binding material that holds until anaphase of mitosis and meiosis. (JN)

Investigated social networks and friendship patterns of high school physics students (N=10). Results did not support hypotheses that students would have established strong social networks and that friendship linkages would result in establishment of links composed of one best friend, one or two close friends, and one or two friends. (Author/JN)

This study set out to determine the relationship of each of 12 selected cognitive factors to physics achievement at the high school level. Multiple regression analysis indicated that the most promising predictors for boys were divergent production measures; convergent production for the girls. (Author/GK)

Indicates that science educators should help students perfect the ability to communicate in technical and scientific areas, focusing on the need for writing skills in science and offering suggestions for skill building. (Author/JN)

Energy-Environment Simulators, provided by the U.S. Department of Energy, can be used to help individuals experience the effects of unbridled energy consumption for the next century on a national or worldwide scale. The simulator described is a specially designed analog computer which models the real-world energy situation. (MP)

Presented is one of a series of articles designed to help science teachers keep current on ideas in specific areas of biology. This article provides information about ion transport in plant cells. (PB)

Discusses the origin and intended meaning of the phrase "survival of the fittest." Traces the concept of "fitness" in a neo-Darwinian sense and outlines the use of the term in other contexts. (Author/MA)

Using three specific works of art, the author demonstrates how a study of selected landscape paintings can be integrated into units on landforms in secondary school earth science and general science courses. (Author/SJL)

Described is an annual science bowl held in Havenscourt Junior High, Oakland, California, for ninth grade science students. Patterned after TV's "College Bowl," the science bowl involves panels of students competing to answer objective questions and practical challenges. Indirect benefits to students include increased community support and review…

Presents the course outline for "Science: A Way of Knowing," a content-integrated science course designed for high school students to learn about the nature, the processes, and the social aspects of science. (CS)

Tested the hypothesis that spatial reasoning is a significant correlate both of formal thought, as defined by Piaget's measures of the proportionality schema, and of achievement in science. Sex differences in proportional reasoning and spatial skills in 6th-form (11- year-old) students from a New Zealand high school were also examined. (CS)

Discusses reasons why nutrition should be stressed in secondary school biology programs. (CS)
