Programs should emphasize application, stress useful work, encourage student participation in planning, cross discipline barriers, and relate to real, human, and social problems. They should accommodate differences in student interests and abilities, teacher preference, and local conditions. (DF)

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)

Describes an energy resources ranking simulation program for high school and college students. This program has the major objective of illustrating the complexity of issues concerning energy by involving students in a decision-making process that will call upon information from different disciplines. (HM)

Describes procedures that can help students to make model geodes from eggshells, copper sulfate, and other crystalforming substances. (HM)

Describes an integrated unit on bluebirds that culminates in students building bluebird boxes and creating an informational pamphlet to raise public awareness of the bluebirds' plight. Enables students to become more involved in their community and the environment. (JRH)

Describes the Seabase America project, undertaken by the Copley-Fairlawn Schools in Ohio, in which over 100 high school students spent 6 days living and working in 10 interconnected geodesic domes in a simulated undersea research station. Students engaged in various scientific and educational activities. The project also accommodates elementary…

Describes a science unit used in a fourth-grade class to teach students about Bernoulli's law of flight, the similarity of tetrahedrons to birds, and the construction of tetrahedron kites. Also includes thought-provoking math questions for students. (MDM)

Describes an electronic circuit that can function as a prototype for chaotic systems. Specific applied voltages produce chaotic signals that can be viewed with an oscilloscope or be made audible with a home stereo system. Provides directions for assembly with typical costs, mathematical basis of chaos theory, and experimental extensions. (JJK)

Describes Ohio's Scenic Rivers Monitoring Program that uses benthic macroinvertebrates, such as the stonefly, mayfly, and water penny beetle larva, as key indicators of water quality and stream health. Presents a three-category scheme for invertebrates based upon their tolerance to pollution. Students can collect samples of these organisms,…

Describes how teachers and students can conduct a schoolwide hazardous waste survey. The activity is an introduction to hazardous waste management and is useful in general physical science, chemistry, and environmental science classes. Two activity worksheets are provided. Explains how schools can clean up hazardous waste problems. (PR)

Describes a six-week project, in which students ground their own mirror, built a working telescope, and learned how and why it all works. (PR)

Considers the ways in which students' activities during project work are influenced by their images of science. Finds that the concept of "epistemic demand" may help in anticipating difficulties students might have during science project work, and that students' images of science are developed as a result of implicit and explicit…

Introduces the Meteor Scatter Project (MSP) in which high school students build an automated meteor observatory and learn to monitor meteor activity. Involves students in activities such as radio frequency survey, antenna design, antenna construction, manual meteor counts, and computer board configuration and installation. (YDS)
