Crystallization of Magma is one of a series of single-topic problem modules intended for use in undergraduate geology and earth science courses. Through problems and observations based on two sets of experiments, this module leads to an understanding of how an igneous rock can form from molten material. Environmental factors responsible for…

This annotated bibliography documents traditional isotonic strength training and nontraditional isotonic strength training (isokinetics) to aid the athletic coach in deciding which type and scheme of training will best develop strength. A glossary of terms is provided. Appendices include muscle action charts and tables, body position charts, a…

Describes an interesting, inexpensive, and highly motivating experiment to study uniform and accelerated motion by measuring the position of a car as it crashes into a rigid wall. Data are obtained from a sequence of pictures made by a high speed camera. (Author/SLH)

ONE OF A SERIES DESIGNED TO HELP TEACHERS PREPARE POSTSECONDARY-LEVEL STUDENTS FOR THE AGRICULTURAL MACHINERY SERVICE OCCUPATIONS AS PARTS MEN, MECHANICS, MECHANIC'S HELPERS, AND SERVICE SUPERVISORS, THIS GUIDE AIMS TO DEVELOP STUDENT COMPETENCY IN UNDERSTANDING BASIC HYDRAULICS AND ITS APPLICATION TO AGRICULTURAL MACHINERY. IT WAS DEVELOPED BY A…

Fundamental concepts of motion are presented in this first unit of the Project Physics textbook. Descriptions of motion are made in connection with speeds, accelerations, and their graphical representation. Free-fall bodies are analyzed by using Aristotle's theory and Galileo's work. Dynamics aspects are discussed with a background of mass, force,…

This is a collection of significant papers by leading authorities, compiled by the American Association of Health, Physical Education, and Recreation's Kinesiology Committee of the Physical Education Division. The following papers are included in this collection: "Supporting Biomechanics Subject Matter in the Undergraduate Curriculum";…

Problems associated with energy production and power are studied in this teacher's guide to better understand the impact of man's energy production on the environment, how he consumes energy, and in what quantities. The resource unit is intended to provide the teacher with basic information that will aid classroom review of these problems. Topics…

Reviews the history of selected topics in physical chemistry, including kinetics, thermodynamics, quantum chemistry, and nuclear chemistry. (MLH)

Describes a heat transfer experiment that demonstrates kinetic behavior using measurements of the rates of cooling and warming of liquids. (MLH)

Describes an undergraduate physical chemistry experiment in which the kinetics of the various reactions involved in the flash photolysis of water are analyzed on a computer. (MLH)

Describes an undergraduate experiment that provides instruction in nuclear magnetic resonance (NMR) spectroscopy, reaction rates, and the application of mathematical procedures. (MLH)

Discusses scattering problems in continuous media, and presents a simple discrete model for scalar wave scattering from inhomogeneities on a lattice. Illustrates the relationships between the amplitude of the scattered wave and the characteristic function of the fluctuating motion of a point reflector in one dimension. (Author/GA)

This article shows that the centrifugal force in a rotating reference frame possesses the property that the brachistochrone and tautochrone are identical. In this system the force is repulsive and proportional to the distance from the force center. (Author/BB)
