Instructions are provided for the construction of 4.5 foot diameter planetarium shells. (CP)

Presents information on storage of radioactive wastes, the AAAS February meeting, an NSF publication on doctoral scientists and engineers, the Research Associateship programs of the National Research Council, the international congress on cybernetics, the effects of nuclear war on noncombatants, radioactivity in drinking water, and computer based…

Describes a technique utilizing analyses of photographs to study planetary motion. (CP)

Describes a device which employs two diffraction gratings and three or four simple lenses to produce arbitrary absorption or emission spectra that may be doppler shifted and spectroscopically examined by students some distance away. It may be regarded as a sort of artificial star whose spectrum may be analyzed as an undergraduate laboratory…

Two instruments are described which were designed to provide beginning students with the tools for determining sun-time and the altitude of the sun. Both can be constructed by the student. A simple-to-construct scale is included. Activities are suggested to use with the instruments. (Author/EB)

Oceantides are not typically high in our consciousness here in Missouri, but in teaching astronomy and physical science the subject always comes up, and teachers of physical science and astronomy are all quite familiar with the textbook explanations. Our goal here is not to explain tides but to make some suggestions about how, on their own,…

Describes a device that simulates the scales and motions involved in the observer coordinate system. (GS)

Describes the use of the Keller Plan in a course designed for non-science majors. The students perceived the unit tests and their immediate correction by the instructor as the most important component of their learning. (GS)

Explains macroscopic properties of a number of systems as averaged-out behavior of numbers of particles. The approach is applied to a model of nuclear fission, rotational velocity in a galaxy, the nature of the rings of Saturn, oscillations of the earth, drops on a spider web, and the shape of ruined Meidum pyramid.

This booklet describes the Pioneer Program and its role in exploring the solar system. Sections include: (1) "Pioneers in Space to Understand Our Earth" (describing the background of the program); (2) "First Pioneers"; (3) "The Interplanetary Pioneers"; (4) "Planetary Pioneers"; (5) "Outer Solar System…

This PSI unit may be used as a self-study guide or as part of a PSI or regular astronomy course to provide a simplified procedure for the casting of natal horoscopes. (Author/DT)

Three members of the Ohio State University Astronomy department developed an audiovisual program in Astronomy to provide a format for more active student participation than is possible in large lecture sessions. The program consists of 18 filmstrip/cassette modules and an integrated textbook which were utilized on an individual basis, allowing…
