Illustrates the construction of a classroom demonstration of the moving cube illusion. Gives details for building this three-dimensional figure that appears to be a solid cube but is actually a hollow figure. Suggests ways in which this display may be used in the classroom or as a permanent exhibit. (KO)

This article examines the 11-year Soviet experiment with boys' schools as a way to cast new light on scholarly research and public debates about single-sex education. Drawing on archival and published materials by educators who described school conditions, identified problems, suggested reforms, and evaluated remedies, the author argues that…

Uses inexpensive equipment to demonstrate, through factorial design, an interaction between genetics and environment. Provides instructions for introducing and conducting the experiment, reporting that significant results are usually obtained. Notes the exercise is appropriate for experimental psychology, developmental psychology, behavior…

Describes several ways to demonstrate the relationship between various aspects of auditory stimulation and sensation. Discusses the equipment required to hear and to visualize simultaneously a variety of auditory signals. States that these demonstrations allow students to learn more about sensory processing in general and auditory function in…

Described is a simple demonstration that relates the techniques of magnetic resonance imaging (MRI) used in medicine and nuclear magnetic resonance (NMR) spectroscopy. Included are materials, procedures, and probable results. (KR)

Described is a demonstration that provides an introduction to nonequilibrium reaction-diffusion systems and the coupling of hydrodynamics to chemical reactions. Experiments that demonstrate autocatalytic behavior that are effected by gravity and convection are included. (KR)

Describes an educational experiment conducted at Miami University where graduate cable management seminar students were given hands-on experience in developing programming ideas and producing programs for a cable television channel. Learning objectives, evaluation methods, and faculty and on-site supervisor roles are discussed, and recommendations…

Describes a magic show designed to encourage young children in physics and chemistry. Discusses how a little "razzle-dazzle" can effect children positively. Tells how to organize and perform a magic show. Details six tricks that focus on principles of chemistry or physics. (CW)

Provides a listing of 35 demonstrations designed to generate interest in organic chemistry and help put points across. Topics include opening lecture; molecular structure and properties; halogenation; nucleophilic substitution, alkenes and dienes, stereochemistry, spectroscopy, alcohols and phenols, aldehydes and ketones; carboxylic acids, amines,…

Classroom demonstrations of selected mechanical properties of polymers are described that can be used to make quantitative measurements. Stiffness, strength, and extensibility are mechanical properties used to distinguish one polymer from another. (KR)

Included are three demonstrations that include the phase change of ice when under pressure, viscoelasticity and colloid systems, and flame tests for metal ions. The materials, procedures, probable results, and applications to real life situations are included. (KR)

Describes an experiment that provides a study of the different colors and shapes of crystals of transition metal dimethylglyoxime complexes with the use of a low power microscope. Discusses the preparation and examination of the crystals. (CW)

Describes a program of demonstration experiments used to stimulate interest in chemistry, specifically aimed at increasing university chemistry enrollments. Discusses program goals, experiments, design criteria, and several caveats related to the development of such a program. (JM)

Described are several laboratory investigations that may be used to introduce biochemistry. Topics covered include carbohydrates, lipids, proteins, and metabolism. Reactions, stock solution formulas, and procedures are listed. Emphasized are individualizing work, designing alternative investigations, solving problems, and drawing conclusions. (KR)

Describes two chemistry demonstrations including a demonstration of chemical inhibition and "The Rayleigh Fountain" which demonstrates the polarity of the water molecule. Provides instructions and explanations for each demonstration. (CW)
