Describes curriculum used by the Chemistry Department at the American University of Washington, D.C. in preparing and implementing a program to update two groups of women in order to prepare them to enter graduate school or return to the job market in chemistry. (HM)

Presents an undergraduate physical chemistry laboratory experiment describing the measurement of the proton magnetic resonance spectra. (HM)

Describes the use of sound/slide programs in instruction, how to produce them locally, and the hardware involved. (GA)

Establishes the extent to which practical work in South African high schools varies with respect to factors such as gender of student, type of school, medium of instruction, and examination board. Investigates the relationship between experience of experimental work and pupil attainment as measured by matriculation grade. (Author/GA)

This experiment uses a nine-chambered plexiglas unit to facilitate rapid construction of galvanic cells and measurement of cell voltage. Using this procedure, a pair of students can construct and obtain the cell voltages of two precipitation cells, three concentration cells, and six redox cells in 30-40 minutes. (BB)

The observation of soap bubbles in a beaker of carbon dioxide gas helps students to feel the pleasure that comes from understanding nature, from applying that understanding to real problems, and from making unexpected discoveries that yield to analysis. (Author/BB)

Tracing the ten-year development and operation of a training center for Florida's law enforcement officers, this article discusses the construction plans, the new training center, the professional staff, and the current programs and objectives. (BM)

The author taught in an open-space classroom at Argyle Junior High in Montgomery County, Maryland. Here is a candid look at the inner workings of a room without walls. (Editor/RK)

Describes a series of science activities involving dissection and analysis of a sea necklace. (CP)

Describes an experiment for the measurement of the reflectances of dielectric surface. The experiment is analyzed in terms of the Stokes parameters and the Mueller calculus, and Malus law is derived. The experiment also provides an introduction to the properties of real linear polarizers. (Author/GA)

Describes an experiment in which a point source of light, when viewed through a cylindrical tube having reflecting inner walls, appears as a series of sharply defined rings, due to the multiple reflections from the inner walls of the tube. ( GA)

Experiments to measure range, range straggling, stopping power, and energy straggling of alpha particles are discussed in this article. Commercially available equipment with simple modifications is used for these measurements. (Author/GA)

Describes the preparation of suitable solid electrolytes and cells which may form the basis of a laboratory teaching program designed to illustrate a variety of electrochemical ideas. ( Author/CP)

Reports on a computer batch program that will not only perform routine grading using several grading algorithms, but will also calculate various statistical measures by which the class performance can be evaluated and cumulative data collected. ( Author/CP)

Suggestions on the preparation of various kinds of glass and a demonstration of burning magnesium and dry ice are presented. (CP)
