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)

Describes a method of recording galvanometer deflections when using a d'Arsonval galvanometer to demonstrate forced, damped simple harmonic motion. (SL)

Reports on a variety of topics related to experimental design and analysis in the field of medical education. (CP)

A high school class, housed in a temporary prefabricated structure, designed and built a solar energy element to heat the building. (JD)

This research finds that the experience of time-in-passing is an inverse function of the processing demanded by a concurrent task. An attentional model is suggested and evaluated against the literature. (Editor/RK)

Attempts have been made by Rabinowitz, Mandler, and Patterson (AA 527 084) to show that both recall and recognition involve the accessibility of individual words. Their recall tests preceded recognition tests, or vice versa, thus contaminating each other; a fresh experiment is presented to confirm that this is so. (Editor)

This paper is about an education experiment, the sponsorship and coordination of a series of workshops for teachers by an organization of teaching anthropologists. We plan to discuss the impetus for the formation of such a series of workshops, and then describe and evaluate them. (Author/JM)

An experiment is described in which students in an introductory laboratory can determine all of the relevant energy flows of an ordinary household refrigerator. (Author/CP)

A program to increase and encourage literacy in Tanzania is described: traditional stories were related by tribal elders, tape recorded, translated into the national language, printed, and distributed to individuals just learning to read. Cultural relevance of the stories should promote interest in continued reading. (AV)

The author reviews an adult literacy training program designed to go beyond status quo maintenance and to develop productive critical consciousness in individuals. Objectives, structure, personnel, and implementation details are discussed. (AV)

Describes Dolci's most recent project, an experimental school for children of the peasant community in Partinico, in western Sicily. In no other place in Italy is public education available to children on a full-time basis. (Author/AM)

The hypothesis that letters can be matched on the basis of tactual physical features was tested in three experiments with blind Braille-reading children. (Editor)
