Instructions for reproducing two exhibits from the Exploratorium, San Francisco's science museum, are given. One shows students how white light can be made from red, blue, and green lights. The other helps children discover how small time differences allow them to perceive the origin of a sound. (MT)

Ways of teaching students to communicate effectively using descriptive words and comparative statements are described. Two task cards involving descriptions of experiments investigating air pressure are included. (MT)

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)

Suggestions for developing creative and original science fairs include trying new categories, issuing a challenge, and involving the community. (DF)

Sections include the following: (1) "Introducing the Craftsman/NSTA Young Inventors Awards Program"; (2) "Teaching Invention"; (3) "Young…

Discusses the use of high school students to present physics demonstrations to first graders. (MKR)

Almost every school in the United States has natural areas nearby that are often overlooked as learning sites. The intent of this document is to provide educators with a platform to begin natural resource programming at sites near their school. Philosophical as well as concrete information is outlined to provide both intrinsic and conceptual…

Using many different media, students can turn leaves into images which can be used for study, bulletin boards, collections, and identification. The simple techniques described include pastel printing, smoke prints, ink or tempura printing, bleach printing on t-shirts, ditto machine printing using carbon paper, and making cutouts. (DH)

Discusses planning necessary for a successful elementary school science fair. Includes a science fair checklist. (JN)

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)

Building bankhides (areas for trout to rest, hide from predators, and wait for their next meal) is one project of the Bettendorf (Iowa) Community School District's K-12 field science programs. Discusses sixth graders involvement and related activities in the bankhide project. (JN)

Describes a long-term project, Moonwatch, which introduces the relationships between the earth, sun, and moon, highlighting the broad conceptual themes of patterns and change. (MKR)

This article offers quick, inexpensive activities for teaching concepts in three basic areas of the elementary science curriculum (air, sound, and light) with instructions for assembling more sophisticated laboratory tools (e.g., an electroscope and a balance scale). Hands-on science activities that use household items are described. (SM)

The number of students in the science classroom who are learning English as a Second Language is increasing each day. This paper describes preliminary results of a California-based Teacher Enhancement project intended to increase elementary school teachers' science knowledge and ability to teach science to minority students and to promote the…
