An experimental psychology course which analyzes the broad probability of operant conditioning is described. (DE)

A course in teaching research methods in an experimental child psychology course is described. (DE)

Describes an experiment, using a soap bubble raft, intended to provide insight into the orderly packing of spherical objects and the properties of metallic crystals. Also describes a solubility product experiment which uses barium hydroxide. (MLH)

The use of atomic absorption techniques to determine heavy metals in trace amounts is demonstrated by analyzing a solution of human hair digested in nitric acid. (MLH)

Describes qualitative and quantitative experiments using ion exchange columns; after introductory exercises the students determine the total ion concentration in sea water and blood plasma. (MLH)

The present investigation examined experimentally the effect of a learning center environment, with its stated emphasis on independent and individualized study, on the academic performance, self-esteem, self-responsibility, school attitudes, and attendance of elementary school children. (Author)

Describes a method in which the effect of impurity ions in the dielectric is taken into account in the operation of the Kerr cell. (Author/CP)
