1. Starfield: This computer – generated starfield stimulates the night sky at any time, season or location on earth. Over 3,000 stars are projected to a limiting magnitude of 5.5 with the 14 brightest stars individually lensed to produce intense pinpoint images. Star locations are accurate to within I minute of right ascension and 6 minutes of declination. Betelgeuse, Rigel, Antares, Capella and Pollux apprear in full color. Twelve apertures show the position of the sun throughout the year.Applications: Beginning and advanced astronomy

2. Constellation: Using the well-known constellation identification system of H.A. Rey, this cylinder features the 48 major constellations, the ecliptic and celestial equator, colorfully displayed for the ultimate in visual retention.Applications: Star identification, planetary positions and the path of the sun and moon. Useful at all grade levels to facilitate rapid orientation for outdoor observations.

3. Weather: The Weather cylinder depicts the earth's atmospheric circulation patterns including location of the wind systems and jet streams, as well as high and low air pressure masses. This colorful cylinder, in conjunction with A Current Affair, a 20-page curriculum booklet by Gary D. Kratzer, enables students to interactively explore pressure systems, storm systems, longitude and latitude coordinate plotting and other global weather phenomena. Students can even investigate the significance of the wind systems on the routes of early explorers and lean how the jet streams influenced military decisions during World War II.Applications: Adds a new dimension to teaching earth science, weather patterns, the age of exploration, navigation and history.

4. Earth: This cylinder is a projection of the entire terrestrial globe including all of the earth's land and ocean masses. Longitude is displayed at intervals of 15º, latitude is displayed every 10º, with a scale of projection of 1 inch = 40 miles. It is superior to flat maps in its total elimination of distortion, and is useful for studying weather patterns, ocean currents, time zones, social studies and current events. Applications: For the study of geography, earth science, geology and navigation.

5. Plate Tectonics: This global projection is based on the work of Dr. Paul D. Lowman on the Continental Drift Theory at the Goddard Space Flight Center. This map shows active ridges, faults, spreading centers and volcanic activity over the past 1 million years. Identification keys are clearly visible, making earth science instruction at junior high through college levels easy to illustrate. Applications: For earth science and geology5. African Mythology: This colorful cylinder depicts constellation figures as seen by many African cultures such as the Dogon, Bushmen, Masai, Egyptians and more. The appearance of these constellations marked key events such as the beginning of the planting season, and signified important moral lessons. Applications: Useful for astronomy, mythology, art, literature, social studies and history for all grade levels.

6. Greek Mythology: A colorful combination of traditional artwork and folklore for 45 classical Greek constellations is featured on a background of 3000 stars, making this cylinder an excellent introductory tool for locating constellations. A convenient identification key includes folk legends about each constellation.
