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 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)

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)

Described is a science classroom program with centralized materials, and assistance and workshops for teachers. Classroom materials on one of five topics rotate every six weeks among five schools. Teachers plan specific units to match the arrival of the materials in their schools. (Author/DS)

This article tries to provide both a justification for primary science and an introduction to the kind of science which can be fostered by nonspecialist class teachers in primary schools. (KC)

To prevent increasing personal injuries and property loss, teachers need to educate themselves and their students about geological hazards. The author discusses earthquakes, downslope movement, dam failures, shoreline erosion, and other geologic hazards. Information on suggested teacher resources is provided. (DS)

Presents a variety of elementary games and learning activities for language arts, reading, math, and science which all relate to the theme of dinosaurs. (SJL)

Suggests how elementary teachers can go beyond the science text and use commonplace materials to create science experiments which sharpen students' observational skills and their ability to formulate testable hypotheses. Seven experiments are outlined, using materials such as paper, cotton socks, and mayonnaise. (SJL)

With field trips curtailed by budget cuts, this elementary teacher provides outside learning experiences in science and social studies by encouraging her students to write letters. In this way, students have requested learning materials, invited guest speakers to visit the class, and learned about other countries through pen pals. (SJL)

Discusses how minicourses offered to elementary school teachers can provide background information and experiences in topics such as aquatic biology and environmental education. Presents results of a questionnaire that evaluates the effectiveness of this approach in aiding elementary school teachers to teach science. (CS)

Illustrated and described is a convection box for classroom use to stimulate concept development in elementary school children. Other equipment and apparatus that may be used in open-ended science activites are listed. (CS)

Describes the process of collecting and maintaining a culture of protozoa. Instructions are also given for constructing a micropipette for transfering small organisms. (SA)

Describes and details the construction of a land-water environment using an aquarium and variety of terrestrial and aquatic materials and organisms. Suggests activities such as identification of organisms, observation of predator-prey interactions, construction of food webs, and recognition of interdependence of biotic and abiotic factors. (CS)

Lists experiments and activities that will aid the young child in understanding the relationship between the position of a body in space and the directions of the force of gravity. (CS)
