Suggests use of the planarian D. Dorotocephala, an animal 20 mm in size, in order to provide inexpensive lab experiences for students in large introductory psychology courses. The animal can be used to study perception, memory, behavior modification, and group processes. (Author/AV)

The locus of control of subjects may be the confounding variable affecting the acceptance of motivational cues in intentional-incidental (INT-INC) learning studies, and thus the reason for conflicting results in "funneling effect" (leaning toward intentional learning as a function of motivation) experiments. 96 female college students selected for…

Abt Associates, the firm responsible for the primary analysis of the Follow Through experiment, summarize the findings. Their clearest finding indicates that local circumstances, attitudes, and activities unmeasured by evaluation have much more to do with the effectiveness of Follow Through models, without exception, than do their theoretical…

Discusses the determination of eutectic composition, the mathematics of chemical equilibrium, the wave functions of one-electron orbitals, and the use of pharmacological agents in introductory chemistry courses. (SL)

Describes experiments involving the synthesis of compounds which exhibit pronounced color changes with changes of solvent polarity. (SL)

Provides a listing of articles and papers published in 1976 relating to various fields of biology and presents various biological science activities. (SL)

Provides a series of learning center activities which demonstrate concepts about air. (CP)

Describes six different plants which will respond to various artificial stimuli. (SL)

Presents basic theory of silicon solar cells and discusses their use in experiments in undergraduate teaching laboratories. (SL)

Reviews classroom teaching ideas including burning sugar cube experiments, science library reference materials, and growing salt crystals. (SL)

Using winter snow, kindergarten students can explore the properties of water. Students demonstrate melting, freezing, expansion, and evaporation through a number of activities involving a paper cup and a scoop of snow. Procedures and student reactions are described in detail by the teacher-author. (MA)

Describes an undergraduate spectroscopy laboratory experiment involving the absorption spectrum of benzene. (SL)

Describes an undergraduate experiment using nmr spectroscopy to study rapid exchange reactions in solutions in which reaction rates are varied by adjusting reagent concentrations. (SL)

Describes apparatus for demonstrating magnetic lines of force, plastic discharge tubes, minimum angle of deviation of light passing through a prism, light scattering, and measuring high voltage. (SL)
