Reports on a method of determining the coefficient of friction of an object through the use of a record turntable. (CP)

Describes the experimental procedure used in determining the lifetime of tantalum-181. (CP)

Presents an undergraduate laboratory exercise in elementary statistics in which students verify empirically the various aspects of the Gaussian distribution. Sampling techniques and other commonly used statistical procedures are introduced. (CP)

For teachers in search of an easily obtainable, readily dissectable, and unique living specimen to arouse the interest of their students and illustrate important biological principles, lichens are the perfect selection. Background information and experiments on lichen anatomy, physiology, and chemistry are given. An appendix gives culture media.…

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 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)

Describes a synthesis of chrysanthemic acid which has been used successfully in a laboratory course. (Author/CP)

Reports on an undergraduate laboratory course designed to provide instruction and practice in the intellectual skills of application, analysis, and synthesis, and in Piaget's formal operations. A 10-item exam used to measure these skills is included as an appendix. (Author/CP)
