To introduce right brain activities into the elementary school curriculum, science activities were generated for gifted children in which every item for investigation was made from a three-by-five card. Three major steps were repeated in developing activities: copying materials, adapting materials, and inventing materials. (SW)

Describes an experimental project on boomerangs designed for an undergraduate course in classical mechanics. The students designed and made their own boomerangs, devised their own procedures, and carried out suitable measurements. Presents some of their data and a simple analysis for the two-bladed boomerang. (Author/MLH)

Describes a secondary project in which students must organize an expedition to settle the people of the Earth on a new planet. (MLH)

Historical uses of Arum maculatum (L.) are summarized. Temperature changes during spadix maturation, spathe uncurling in the presence of flower tissue, indol-3-y1 acetic acid, and gibberellic acid are investigated in the laboratory. Dilute solutions of both phytohormones cause significant spathe uncurling. Further investigations are suggested.…

Describes activities to stimulate school astronomy programs. Topics include: counting stars; the Earth's centripetal force; defining astronomical time; three types of sundials; perceptions of star brightness; sunspots and solar radiation; stellar spectroscopy; number-crunching and the molecular structure of the atmosphere; the Earth-Moon common…

Explains the typical design, operation, and calibration of a traditional psychrometer. Presents the method utilized for this class project with design considerations, calibration techniques, remote data sensing schematic, and specifics of the implementation process. (JJK)

Described is how to build a solar furnace model. A detailed list of materials and methods are included along with diagrams. This particular activity is part of an audiotutorial unit concerned with the energy crisis and energy alternatives. (MA)

Science is an often ignored subject in the elementary grades. This article lists and briefly discusses ten suggestions for strengthening and enriching an elementary science curriculum. Among the ways given are science fairs, museums, outdoor learning centers, filmstrips clinics, and school weather stations. (MA)

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)

Tips are given for collecting and identifying diatoms for use in secondary school biology classes. Collecting sites described vary from freshwater to terrestrial habitats. (SA)

This book presents 15 tales that bring the animal world into the classroom. The stories in this book are divided into two sections: stories from aquatic ecosystems (both fresh- and saltwater systems), and from terrestrial systems, including desert, meadow, woodland, mountain, Arctic tundra, savanna, pine forest, and jungle ecosystems. All predator…

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

Describes a school project on energy conservation, in which fifth and sixth grade students involved the town community in becoming aware of the extent of the energy shortage and considering modes of cutting down on energy usage. Included are ideas for projects and science fairs. (CS)
