This paper describes a multifaceted agitation and mixing experiment. The relatively inexpensive apparatus includes a variable-speed stirrer motor, two polycarbonate tanks, and an instrumented torque table. Students measure torque as a function of stirrer speed, and use conductive tracer data to estimate two parameters of a flow model. The effect…

Conversion of a University of Oregon bowling center into a computer laboratory by the college union is discussed. Located in a renovated former bowling center, the Erb Memorial Union Computer Lounge is a self-supporting campus computer laboratory. User fees are charged for on-site computer rentals, laser printing, color plotting, and typesetting…

This experiment uses a radioactive technique to determine the relative leaving abilities of chloride and iodide in nucleophilic substitution reactions. (DT)

Two experiments are described which illustrate preparative as well as mechanistic features of the reactions of halogens with alkanes and alkenes. (DT)

By concentrating radioactivity contained on luminous dials, a teacher can make a high reading source for classroom experiments on radiation. The preparation of the source and its uses are described. (DT)

Describes procedures and materials for preparing microscope slides. Comments on selection and proper care of slides are also included. (RH)

Discussed and described are analytical instruments available for chemical analysis in 1940-41. (RH)

This paper describes a computer model that simulates experimental outcome data obtained by the manipulation of 13 independent variables reported in studies investigating the group risky shift. The model is intended as a tool for teaching research methods in an undergraduate course in social psychology. (Author)
