Science Games

There used to be a chain of stores called Zany Brainy that sold educational toys and multi-media products aimed at kids aged 4-12 that has since gone out of business. Its merchandise included games and puzzles; infant development toys; books, audiocassettes, CDs and videos; arts and crafts; building toys and trains; computer software; electronic learning aids and musical instruments; science toys; plush toys and dolls; and sports-themed toys. You could find items related to science, weather, fossils, nature…things like that. Anyone know of any websites that sell interesting things like that aimed at kids?
