Discusses the chemistry component of a five-week summer program for talented high school juniors and seniors at the Pennsylvania Governor's School for the Sciences. Describes the chemistry core, lab component, team projects, and program results. (CW)

Details three demonstrations for use in chemistry classrooms. Includes: "A Demonstration of Corrosion by Differential Aeration"; "A Simple Demonstration of the Activation Energy Concept"; and "A Boiling Demonstration at Room Temperature." Each description includes equipment, materials, and methods. (CW)

Describes an experiment to be performed in an undergraduate biochemistry laboratory that is based on a gradient centrifugation system employing a simple bench top centrifuge, a freezer, and frozen surcose gradient solution to separate macromolecules and subcellular components. (CW)

Describes a kinetic and mechanistic investigation of ascorbic acid by a substitution-inert complex in acidic medium suitable for the undergraduate level. Discusses obtaining the second order rate constant for the rate determining step at a given temperature and comparison with the value predicted on the basis of the Marcus cross-relation. (CW)

Describes the "Grow Lab" program which is sponsored by the National Gardening Association. Discusses how eight square feet of classroom space are converted into a mini-ecosystem. Mentions the development of a curriculum guide to accompany the indoor garden. (TW)

Analyzed and compared the teaching behavior of teachers who had been trained to use Science Education Project (SEP) materials with the teaching behavior of teachers using traditional approaches. Reviewed some relevant research on observations of science teaching and presented the results of the comparative study. (CW)

Discusses some of the problems in enrollment in academic engineering programs, particularly in electrical and computer engineering. Describes the teaching engineering program at Utah State University in an effort to address these problems. (TW)

Encourages teachers to take advantage of the natural curiosity of young children in enhancing their interest in science. Describes four simple activities involving water, living and non-living things, air pollution, and food. (TW)

Describes an introductory course required of all engineering students at the Ecole Polytechnique de Montreal (Canada). Discusses the design of the course, including its emphasis upon the facets of engineering careers, direct experience, and written and spoken communication. (TW)

Reports on a study designed to compare the effects of two instructional treatments in which the experimental treatment emphasized self-management, goal clarification, and individualized course expectations. An increase in science locus of control was found to be significant for the experimental group. (TW)

Presents a framework for model development that, when used, will help the student (or professor) avoid the major pitfalls associated with modeling. Includes not properly identifying the controlling factors, lack of model validation and developing a model that is incompatible with its end use. (CW)

Reports on the results of an investigation into the understanding of the concepts of basic electricity by French students from grade six up through the fourth year of college. Discusses the misconceptions formed and the challenges these present to physics educators. (TW)

Presents five problems on organic stereochemistry in the form of an open-book quiz meant for senior undergraduates and graduate students in chemistry. Provides some acceptable solutions to the problems. (TW)

Discusses combustion by suggesting several experiments and demonstrations using matches. Integrates quotes from famous scientists about the various phenomenon regarding combustion. (TW)

Proposes the use of a relative atomic mass (RAM) scale in which hydrogen is assigned a value from one as a teaching aid for better understanding the concept of RAM. Helps to clarify the ideas and concepts about this topic. (CW)
