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)

Described is the first part of a two-term project involving final-year students in biochemistry. Listed are the required experiments compiled to test students' abilities to search biochemical literature, extract experiments from journals and carry them out, generate data, and interpret results. (CS)

Describes several significant observations by amateur astronomers of recent, spectacular clouds and storm systems on Mars, Jupiter, and Saturn. (Author/JJK)

Describes a project where students were given a small but real scientific question and allowed to deal with all aspects of the project just as a professional scientist would, rather than work on the science part only. (JRH)

Discusses how to make and fly boomerangs. (BB)

A proliferation of new government regulations and other events in recent years has made it more and more difficult to teach science and engage in science activities. Rapid advances in biotechnology have made it difficult for both students and teachers to stay abreast of current events. These difficulties along with others have turned some teachers…

Describes the construction and operation of a simple field mill to measure atmospheric electric fields. (Author/CP)

Describes construction of a variety of relatively inexpensive cameras for astronomical purposes. (CP)

The relationship between tadpoles, algae and drinking water for wildlife is discussed. Six projects that students can do to learn more about the ecological benefits of tadpoles and frogs are described. A bibliography is included. (AJ)

Describes how to set up an economical saltwater aquarium and where to obtain supplies and inhabitants. Discusses the characteristics of a saltwater aquarium, proper aquarium maintenance, the compatibility of diverse life forms, and the time scale necessary to develop and sustain a favorable natural environment. (nine references) (Author/JJK)

Describes a project that helps students integrate biological concepts using both creativity and higher-order problem-solving skills. Involves students playing the roles of junior scientists aboard a starship in orbit around a class M planet and using a description of habitats, seasonal details, and a surface map of prominent geographic features to…
