Directions are given for caring for desert tortoises, both adults and young. Observations of their behavior are recommended. (SA)

Presents activities for the elementary teacher to use in helping children to enjoy a small path of undeveloped land in an urban area. Teaching about plant roots is explained. Also included is the equipment needed and how to prepare for the root activities. (SA)

Provides guidelines prepared by the National Science Teachers Association for the use and care of invertebrate and vertebrate animals in the classroom. Suggestions are made for conducting experimental and observational studies. (CS)

Described is a resource idea developed for the teaching of oceanography to junior high students. Sand is studied to help make the study of beaches more relevant to students who may have never seen an ocean. Sand samples are brought into the classroom from various coastal cities, then analyzed and compared. (Author/DS)

Described is a method of photographically recording the seasonal movements of the beach, and the equipment and details used in this method. Included is a method for determining current speed and instruction for construction of a tin can viewing box to be used in underwater sea form observations. (Author/DS)

Described are several activities to be used to help students grasp the concept of floating. The activities include the use of a spring scale to measure the weight of the objects in air, in water, and in salt water, and a discussion of why there are differences in these weights. (DS)

Discussed is the intertidal region and the characteristics and adaptations of the organisms that live in that region. Several activities that involve the intertidal region are described, which reinforce the adaptive behaviors and forms of the organisms found in the intertidal region. (Author/DS)

Described is a junior high science curriculum which lists two purposes, emphasis on activities and studying science topics which are meaningful to early adolescents. A curriculum that offers opportunities for adolescents to explore each of the five senses and their attributes is outlined. (Author/DS)

Describes several elementary science learning experiences and activities concerning the concept of space. Activities described include tracing children's shadows at different times of day, moon observations, and planetarium activities. (DS)

Suggested are feature topics for a regularly published classroom newspaper devoted to science. Reasons for such a newspaper include integration of more science into the curriculum and reinforcement of basic skills. (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)

Instructions are given for working with a class on building kites. Included are the plans for a bullet kite, a section on the history of kites in America and spin-off activities from the kite exercise. (SA)

A technique is described whereby the center of an irregularly shaped object can be determined. Several activities are suggested that require the use of a piece of cardboard mounted at its center of gravity. (SA)

Describes a summer science program for suburban upper-elementary and junior high students. The students are involved in field ecology experiences including stream studies, fossil collecting, and dissections of organisms. (SA)

Suggests that a variety of approaches to teaching science should be used so that concept development occurs. Sensory experiences alone may not be enough. It is suggested that the current trend towards "hands-on" learning may represent a reaction to overemphasis on the verbal and abstract in science. (Author/SA)
