Educational insights experiment set geosafari Learning Toys

Look! It's Leo! This is one slick motorized solar system and planetarium from Educational Insights®. Make assembling it an educational exercise. Demonstrate how the planets circle the sun. The 4" dia sun is yellow plastic, lit with a krypton bulb. The planets are colored, reasonably proportional given their actual sizes, and marked with their symbols. They ride on black metal arms that disappear in the dark. The helpful instruction manual suggests activities, and includes a heliocentric longitude chart. Use it with the degree markings on the black-plastic base to show the positions of the planets on different dates. Replace the top half of the sun with the clear dome imprinted with labeled Northern-hemisphere constellations, and project them onto the walls and ceiling of your darkened classroom. About 9" high, with Pluto extending 15" from the center, and the other planets hanging out in their respective order. Comes with an AC adapter, but not with the (4) "C" batteries it needs. For grades 3 and up, and not for kids under three years of age. (Do you want to have to tell an E.R. nurse he ate Uranus?)
