Describes the distinctive features of the common snapping turtle. Discusses facts and misconceptions held about the turtle. Provides guidelines for proper care and treatment of a young snapper in a classroom environment. (ML)

Provides background material which relates to the concept of activation energy, fundamental in the study of chemical kinetics. Compares the related concepts of the Arrhenius activation energy, the activation energy at absolute zero, the enthalpy of activation, and the threshold energy. (CS)

Interprets the physical quantity, extent of reaction, as it is used to describe yields, rates, and energy changes associated with chemical reactions in a quantitative manner. (CS)

Presents a mechanical model for an ecology laboratory that introduces the concept of optimal foraging theory. Describes the physical model which includes a board studded with protruding machine bolts that simulate prey, and blindfolded students who simulate either generalist or specialist predator types. Discusses the theoretical model and data…

Considers several cosmological facts that relate to formulating accurate models about the universe, including the red shift, the unbounded universe, and the curvature of space. (CS)

Describes urinalysis techniques for dry weight measurement, examination of urinary calculi (stones), and determination of the presence of blood and blood pigments. Also presented are directions for preparing required reagents. (WB)

Presents a model of the cardiovascular system which solves a set of interacting, possibly nonlinear, differential equations. Figures present a schematic diagram of the model and printouts that simulate normal conditions, exercise, hemorrhage, reduced contractility. The nine interacting equations used to describe the system are described in the…

Presented is geological information and site descriptions for teachers to use in planning and conducting earth science field trips in Virginia. Among the topics included are: (1) Geology, Soils and Land Use in Central Virginia; (2) Using Coastal Plain Stratigraphy Near Fredericksburg, Virginia as a Teaching Tool; and (3) The Culpepper Basin of the…

Discusses electron-loss spectroscopy and the experimentally observed excitation energies in terms of qualitative MO theory. Reviews information on photoelectron spectroscopy and electron transmission spectroscopy and their relation to the occupied and unoccupied orbital levels. Focuses on teaching applications. (ML)

Discusses who takes college-level courses on solar energy; what material should be covered; sources of texts, outlines, curricula, and teaching aids; kinds of equipment needed; and science-, business-, and vocationally-oriented programs to prepare for such solar energy careers as design, research, education, and construction. (Author/JN)

Describes an application of solid-state memories in a laboratory course, which enables students to build electronic devices. Also introduces the fundamentals of analog-to-digital conversion and sampling theory. (CS)

Outlines a variety of laboratory procedures, discussions, and demonstrations including polarizing power and chemical properties of copper and zinc, preparation of boron coordination complex, demonstration of amino-acid synthesis in the primordial environment, classification and reactions of carbohydrates, and four others. (DS)

This book presents the life stories of 10 women who work in various fields of science as well as information on education and financial aid and getting a good job (focusing on jobs in academia and industry). The life stories, based on interviews with women scientists, are organized according to their academic fields: (1) biology--Dr. Beatrice…
