A set of instructions for growing algae successfully in the classroom and maintaining the culture is provided. Aids for identification of freshwater organisms are suggested. (SA)

Explains how a shoreline is formed and how it changes, and why its changes do not always coincide with human plans. Subjects discussed include beaches, beach processes, inlets and beaches, and a marine glossary. (Author/DS)

Describes the collection, care, and maintenance of protozoa by elementary school students. Techniques for collecting and observing them are given. (SA)

Included are diagrams of 12 common plants with descriptions of their seed distribution mechanisms. (SL)

Reviews the "Holt Elementary Science Series," favorably describing the format of the materials while identifying weaknesses and inconsistencies in illustrations, content, and vocabulary development. Presents a positive review of "Discovery Activities for Elementary Science" which provides a variety of environmental, physical, and life sciences…

Suggests the use of spores and spore-producing structures to show adaptations facilitating spore dispersal and dispersal to favorable environments. Describes several activities using horsetails, ferns, and mosses. Lists five safety factors related to use of mold spores in the classroom. (DS)

Techniques are described for using living plants in the elementary science classroom including the germination and planting of seeds, transplanting seedlings, vegetative propagation, stem and leaf cuttings, and other plant studies. (DS)

The construction and stocking of an in-class pond is discussed. Suggestions for eight activities using the pond are provided. A list of 15 references is included. (CW)
