Describes the use of a faceted geodesic structure in place of the true spherical dome in the construction of an effective and modestly priced planetarium. Indicates that the construction can be undertaken as a student group project. (CC)

Investigation reported in this paper is primarily concerned with how project work affects the attitudes that pupils hold towards science and in what ways the project affects the attitudes that pupils already hold. (Author/CB)

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)

Activities for teaching about the solar system, the earth's rotation, plants, pendulums, and animal adaptation are described. Included are suggestions for building scale models to illustrate the solar system's proportions and the earth's rotation speed, and for using playground swings to demonstrate pendulum motion. (PP)

Presents background information, materials needed, and experimental procedures to study enzymes dependent on pyridine nucleotide coenzymes (NAD/NADH). The experiments, suitable for advanced organic or biochemistry courses, require approximately 10-15 hours to complete. (SK)

Describes a series of experiments which a group of 12- to 14-year-old students developed and conducted as they attempted to design a solar panel. Includes an outline of their building procedures. (DC)

Recognizing the importance of scientific research to the preservation of national security, the U.S. Navy uses its Navy Science Awards Program to encourage students in scientific pursuits. Described are purposes, operation, awards, and perceived value of the program. (DC)

Discusses various methods the author has used in high school chemistry classes to maintain interest and keep grades at an acceptable standard. Integrated within the curriculum are research projects, library research, creative work, laboratory write-ups; a two-level curriculum is provided for nonscience and science majors. (CS)

Presents an analysis of student science projects at science fairs that judges are likely to encounter. Presents a challenge to the organizers of science fairs to define the goals of the fair and the criteria for selecting winners. The problems associated with the process are discussed. (SA)

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)

Describes a chemistry program offered at East Mecklenburg High School in Charlotte, North Carolina. The philosophy underlying this program and its teaching techniques are also included. (HM)

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)
