Describes an undergraduate experiment. Discusses a model for the behavior of bubbles under differing viscosities and pressure gradients and conditions for failure of the model. (GH)

Discusses an experiment involving a linear chain of falling dominoes. The time for a chain of N equally spaced dominoes to fall is measured and a plot is made between the time and N. The experimental data are compared with the predictions of theory. (Author/GA)

A model of Brownian motion is discussed which includes viscosity effects. The model lends itself to Monte Carlo simulation and thus is suitable for an elementary physics laboratory experiment. (BB)

Describes the construction and use of a life-size model which shows blood flow under normal and pathological conditions. Four experimental procedures (single vessel occlusion, dilation of distal vascular bed, single artery stenosis, and multiple artery stenoses) typical of those demonstrated by the model are discussed and diagrammed. (DH)

Provides three descriptions of demonstrations used in various chemistry courses. Includes the use of a simple demonstration model to illustrate principles of chromatography, techniques for using balloons to teach about the behavior of gases, and the use of small concentrations of synthetic polyelectrolytes to induce the flocculation hydrophobic…

States that if photochemical reactions can be followed spectrophotometrically, reactivities can be estimated by evaluating data from only one curve. Studies such a system using computerized evaluation and simulation. Uses chlorocuprate(II) complexes in acetonitrile solutions for the model systems. (MVL)

Describes the use of analysis of rotational faults in undergraduate structural geology laboratories to provide students with applications of both orthographic and stereographic techniques. A demonstration problem is described, and an orthographic/stereographic solution and a reproducible black model demonstration pattern are provided. (TW)

This monograph discusses the care and maintenance of animals, suggests some alternative teaching strategies, and affirms the value of teaching biology as the study of living organisms, rather than dead specimens. The lessons in this monograph are intended as guidelines that teachers should adapt for their own particular classroom needs. Chapter 1,…
