Describes an inexpensive method of measuring energy expenditure during exercise. Presents the materials needed to conduct the experiment, basic principles, procedures, calculation and analysis, and a discussion of results. (ZWH)

Describes the working of the Adiabatic Gas Law Apparatus, a useful tool for measuring the pressure, temperature, and volume of a variety of gases undergoing compressions and expansions. Describes the adaptation of this apparatus to perform isothermal measurements and discusses the theory behind the adiabatic and isothermal processes. (JRH)

Outlines the use of the toy popularly known as Newton's Cradle or Newton's Balls in illustrating the laws of conservation of momentum and mechanical energy. Discusses in detail the joint effects of elasticity, friction, and ball alignment on the rate of damping of this apparatus. (JRH)

Presents an experiment that demonstrates conservation of momentum and energy using a box on the ground moving backwards as it is struck by a projectile. Discusses lab calculations, setup, management, errors, and improvements. (JRH)

Discusses a series of experiments to establish a significance of temperature difference in rates of cooling, to illustrate the connection between energy transfer and the consequent temperature changes for thermally connected systems that are not in equilibrium. (MKR)

Presents a science project involving the production, transportation, handling and preparation of food for human consumption. Calculations of caloric value of the food intake and the energy costs of cooking are included. (Author/SA)

Spectroscopic aspects of the triboluminescence spectra of three Lifesaver candies are discussed. Emphasis is placed on the experimental methods of measuring spectra and origins of the tribaluminescence. (SA)

An experiment on the heat conductivity of different materials are described. Applications for energy education in the elementary classroom are implied. (MDR)

Describes several different philosophies of mind with each philosophy's explanation of the mind-body problem. Philosophies discussed include dualism, materialism, functionalism, radical behaviorism, logical behaviorism and central-state identity. (DS)

Presents experiments that use the Mattel's Hot Wheels Top Speed toy set to show that work is a measure of energy transferred to or from a system. (JRH)

Uses a vortex device as a model to study low-pressure systems and other related investigations. (LS)

Describes four science experiments relating to energy developed for interdisciplinary general science courses. (SL)

Presents basic theory of silicon solar cells and discusses their use in experiments in undergraduate teaching laboratories. (SL)

Offers a series of hands-on activities for introducing students to concepts of energy transfer and conversion. Describes how simple devices as marbles, ramps, and sliders can be used to gauge the transfer of energy and assist in the development of investigative skills. (ML)

Often elementary and junior high teachers search for effective, inexpensive, and easy-to-understand science activities. This document was designed with those teachers and their students in mind. It provides hands-on science activities that focus around three components: (1) themes--broad, unifying ideas that pervade science, math and technology;…
