Describes a guinea pig (cavy) breeding and management program developed as part of an elementary school science curriculum. Includes comments on show competitions (sponsored by the American Rabbit Breeders Association) to measure the success of the breeding program and to enable children to experience the business world. (Author/JN)

Offers suggestions for using sow bugs in the classroom, including maintenance, source (found virtually everywhere in damp soil), background information, bibliography, and bulletin board idea. Includes instructions and materials (clue cards) for a fact-finding and hypothesis-testing game in which students determine what kind of an animal…

Describes two simple physics experiments demonstrating the spin on baseballs or golfballs and the observed effects of falling coins when released together. (CS)

Describes materials and procedures for an experiment utilizing a live dog to demonstrate: (1) physiology of the salivary gland; (2) parasympathetic control of the salivary gland; (3) influence of varying salivary flow rates on sodium and potassium ions, osmolarity and pH; and (4) salivary secretion as an active process. (DS)

Describes science activities related to Christmas and Thanksgiving, including identification of evergreen trees, tree shapes, pine cone and needle collections, edible decorations, and instructions for preparing bird food called "bird pudding." (SK)

A coding scheme was developed which reflected individual differences among students with various handicapping conditions and their adjustment to "hands-on," activity-centered science materials. The scheme was utilized in the observation of four special education student's interactions with the science materials from Science Activities…

Provided are directions for culturing bacteria by using yoghurt as a culture medium. Yoghurt is a safe medium and results in an end product which may be eaten if desired. (PB)

Described is a student exercise demonstrating plant biorhythms in Albizzia julibrissin. Initial preparation and methods for conducting the exercise are explained, and sample data graphs are included. (CS)

Presents a science project involving the production, transportation, handling and preparation of food for human consumption. Calculations of caloric value of the food intake and the energy costs of cooking are included. (Author/SA)

Describes several general high school chemistry activities including: (1) making Christmas glassware, (2) some energy-related activities, (3) some learning activity modules developed by the Unigraph Corporation, and (4) some consumer chemistry activities. (CS)

A Freshwater Winter ecology course for science teachers is described. Included are a description of the lectures, field activities, field techniques, sampling areas, and sampling methods. (DS)

Summarized are five activities involving collection of postage stamps picturing volcanoes or related scenes for use as part of or at the conclusion of the study of volcanoes. Activity topics include volcanic features, location of volcanoes, related land features where volcanoes are not located, and making one's own volcano stamps. (DS)

Presents a hands-on model that can be used to illustrate basic concepts such as carrying capacity, annual turnover, compensation, and diminishing returns. (MA)

Defines six modes of simulation that have been used in science teaching and learning. Discusses the implications of using simulations in the science classroom. (CS)

Discusses the tensions between science and technology at the levels of secondary effects, the interdependence of scientific and technological advances, and the problem of democratic control. The efforts in scientific cooperation throughout Europe are presented as they relate to communication between scientists and politicians. (SA)
