Garigliano, Leonard J. – Science and Children, 1975
Presents the results of an experiment designed to test two hypotheses: (1) a delay of two weeks at room temperature will have no effect on the viability of fertile chicken eggs and (2) refrigeration will have no effect on the viability of fertile chicken eggs. Experimenters were the author and two ninth-grade students. (PEB)

Science and Children, 1992
Presents an activity that is part of the National Science and Technology Week (NSTW) 1993. Students apply principles of biomechanics to find the most effective techniques for performing a standing broad jump and use that analysis to improve their own jumping. Instructions include procedures, materials needed, and possible extensions to the…

Moore, Grace J. – Science and Children, 1991
Students conducted an experiment to study the plant growth of three Amaryllis plants. Students examined the speed and amount of growth, cross-pollinated the plants to produce seeds, and compared the growth of amaryllis seeds to the growth of onion seeds, a plant in the same family, Amaryllidaceae. (MDH)

Leyden, Michael, Ed. – Science and Children, 1985
Provides guidelines for simple acceleration experiments with string and attached weights as a means to stimulate the reticular activating system (RAS) of the human brain. Several methods (discrepant events, curiosity, choices, and doubt) are suggested for promoting RAS high-level thought. String drop experiments provide concrete experiences with…

Hampton, Carolyn H.; Hampton, Carol D. – Science and Children, 1980
A science and social studies unit developed around rosin is described. Students develop an understanding of the processing of raw material from a plant source into a commercial product and how to protect wood from weathering by preparing, testing, and evaluating varnish and shellac for their wood protective qualities.

Fort, Deborah C. – Science and Children, 1985
Success of the Murch Elementary School (Washington, DC) science fair is due to many factors which are applicable to other schools. Suggestions, ideas, and hints are given in this description of the school's program. Projects with an electrocardiogram, water weeds, and preserving ice are also discussed. (DH)

Shaw, Jean M.; Cliatt, Mary Jo Puckett – Science and Children, 1981
Describes four activities for the elementary science classroom to help students develop their powers of description, explanation, and prediction. Topics of the activities are spool "gears," crystal comparisons, yeast magic, and clay cargo carriers. (DS)
