Super Saturday! A Science, Technology, Engineering and Math Expo

The 50,000-square-foot armory is filled with beakers, calculators and the mad scientists who love them. Hands-on activity booths from the American Museum of Natural History, the Intrepid Sea, Air & Space Museum, New York Hall of Science and the Wildlife Conservation Society demonstrate real-life uses of science. Plus, kids can check out a robotics exhibition, go pawn-to-pawn in a chess tournament and crunch numbers in a math olympiad. Ages 4 and up.
