Computer generated starfield simulates the night sky at any time, season or location on earth. Over 3000 stars are projected with the 14 brightest stars individually lensed to produce intense pinpoint images. Twelve apertures show the position of the sun throughout the year and planets may be added to the starfield.
Using the well-known identification system of H.A. Rey (noted children's author), this cyclinder features the 48 major constellations, the ecliptic and celestial equator. Useful for star identification, planetary positions and the path of the sun and moon.
A full projection of 3000 stars are displayed here against a background of the celestial coordinates, the ecliptic and galactic equator. Right ascension marked in 1 hour intervals, declination in 10 degree intervals and precessional axis plus or minus 13,000 year increments.
A combination of traditional artwork and folklore for 45 classical Greek constellations are featured on a background of 3000 stars making this a great tool for locating constellations. For use in astronomy, art, literature, social studies and ancient history classes for all ages.
This cylinder shows a dramatic representation of the skies as seen by both Pharoahs and slaves of Ancient Egypt. An identification key contains descriptions and legends for 36 extraordinary constellations that represent religious, political and Egyptian social life upon a starry background. The position of the stars have been calculated for the year 2500 BC.
Depicts constellation figures as seen by many African cultures such as Dogon, Bushmen, Masai, Egyptians and more. The appearance of these constellations marked key events such as the beginning of the planting season.
Featuring more than 30 exciting, colorful constellations such as the Royal Coulie, the Supreme Commander and the Awakening Snake. Full of wonderful stories that represent the cultural ideas of the time.
Includes colorful outlines of figures from Indian folklore such as Long Sash, Great Bear, First Man and Woman, Spider God and more. Legends are drawn from Navajo, Cherokee, Tewa, Hopi, Shoshoni, and Algonquin tribes.
Created from legends collected from the Vedas, Ramayana, Mathabharta and Puranas.
This global tectonic projection is based on the work of Dr. Paul G. Lowman on the Continental Drift Theory at the Goddard Space Flight Center. Shows active ridges, faults, spreading centers, and volcanic activity for the past one million years.
Features both warm and cold currents in the world's oceans. Enables students to study the nature of currents, determine what causes them and discover the effects of currents on the Earth.
Depicts the earth's atmosphere, circulation patterns including location of the wind systems and jet streams, as well as high and low air pressure masses. Students can investigate the significance of the wind systems on the routes of early explorers and learn how the jet streams influenced military decisions during World War II.
This one million-times magnification of a composite cell demonstrates the workings of a one celled organism. The processes of digestion and reproduction are illustrated in vivid color. Endoplasmic reticulum, ribosomes, mitochondria, the Golgi plasma, secretion vesicle. lysosomes, pinocytotic vessicules, microvilli, celia, chromosomes and nucleolus are clearly displayed.
This wooden, folded-path, Keplerian telescope provides a much safer and convenient way to view the brilliant light of the sun than other more common methods. By using a series of mirrors, the device projects a bright 3.25-inch solar image onto a 5-inch white viewing screen through a powerful 62mm diameter objective lens. In its perfectly curved cradle, the Sunspotter is easily aligned to the sun in seconds, without the complication of telescopes, solar filters, and tripods. Unlike other ways of viewing the sun, the compact and sturdy Sunspotter is convenient, easy to set up, lightweight and fun to use. And, because of its unique design, this kid-friendly instrument makes our closest star a safer subject of study by even the youngest students. Use the Sunspotter for viewing the sun, eclipses, transits, and for daily record keeping. Track sunspots as they appear, move, and vanish.
