Wheel of Facts

No questions; just information. They're like manual search engines: you turn the 11-3/8" dia wheel and read the facts in the little windows. The Dinoscope features (40) prehistoric beasties with illustrations, a time line, geological periods, pronunciation, meanings of the names, fossil locations, size, habitat and diet. The World Wheel is a compact atlas. Dial any of 192 countries and see the flag, currency, language, population, area, location and capital city. A fun way to learn.
