Presents a technique for obtaining a rough measure of the brightness among different stars. Materials needed include a standard 35-mm camera, a plastic ruler, and a photo enlarger. Although a telescope can be used, it is not essential. (JN)

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

Suggested are activities using a Polaroid camera to illustrate the capabilities of remote sensing. Reading materials from the National Aeronautics and Space Administration (NASA) are suggested. Methods for (1) finding a camera's focal length, (2) calculating ground dimension photograph simulation, and (3) limiting size using film resolution are…

Stereoscopic photo activities for students are described for the purpose of motivating students in earth science. Included also is the necessary equipment for obtaining the three-dimensional effect. (SA)

Equipment and procedures for simple astrophotography are discussed. Sample photographs are provided. Suggested are several uses of the slides and the techniques for teaching astronomy. (CW)

Describes the simple construction and operation of an inexpensive photographic enlarger. (CP)

Provides background information on the equipment and knowledge necessary to do an astronomy activity on the earth's rotation. Details an activity in which students can measure the rotation of the earth using a camera and the stars. (CW)

A classroom technique for projecting microorganisms on a TV screen is described. Instructions are given with a step-by-step approach and effective subject matter is suggested. (SA)

Describes the use of a 35-millimeter camera with color slide film to produce photographs of constellations, star trails, bright comets, aurorae, and meteor showers. Discusses film speed, lenses, f-stop settings, exposure times, and other items related to astrophotographic technique; provides ideas for use of slides in the classroom. (JM)

Discusses the use of remote sensing from satellites to monitor glaciers. Discusses efforts to use remote sensing satellites of the Landsat series for examining the global distribution, mass, balance, movements, and dynamics of the world's glaciers. Includes several Landsat images of various glaciers. (TW)
