Describes a laboratory experiment that begins with a discussion of the fermentation process, the steps of winemaking, the types of wines that can be produced, and the differences between wines. Outlines the procedure for making red wine in the laboratory and describes other types of wine that can be produced. (GS)

Describes an attempt to incorporate research into laboratory work in an introductory ecology class and a senior seminar. The investigation involves the examination of rhythms of food consumption and circadian activities in humans. (GS)

Presents five experiments in which the unknowns for analysis are prepared by the students themselves, the analysis forming an essential part of the investigation. (MLH)

Describes experiments for the undergraduate organic chemistry laboratory which demonstrate reactions and syntheses that involve free - radical intermediates. (MLH)

Describes how to construct an isothermal calorimeter and lists typical results of a displacement reaction using zinc. (LS)

Describes features of agglutinin research utilizing the jack bean and suggests similar experiments for biology students that utilize more familiar plants. (LS)

Provides historical background on Pasteur's resolution of an optically active compound, and describes an undergraduate laboratory experiment in which optically active compounds are separated. (MLH)

Describes a laboratory experiment on geometrical optics designed for life science majors in a noncalculus introductory physics course. The thin lens equation is used by the students to calculate the focal length of the lens necessary to correct a myopic condition in an optical bench simulation of a human eye. (Author/MLH)

Presents information on a centrifugal force apparatus, signal averaging with a minicomputer, and the use of an air track. (MLH)

Proposes method for determination of the pressure of a sphere by relating force and surface tension. (CP)

This study investigates the efficacy of symbolic modeling and role-playing therapy in the reduction of avoidance behaviors. After treatment, role-playing subjects demonstrated significantly less avoidance behavior and lower subjective fear ratings than the modeling or control group subjects. (Author/SJL)
