Science Center: Picnic, Playground, Science, Walk
There’s plenty of neat stuff for little kids to do inside the New York Hall of Science — like making a kaleidoscope in the activity area near the much-beloved Magic School Bus exhibit or seeing their shadow frozen on the wall — but the real fun begins outdoors. An enormous science playground, open from April through December, lets children explore concepts like vantage points, sound, and reflection through obstacle climbs, mirror paths, and whisper dishes. Even traditional playground equipment takes on a whole new meaning: Swings power a windmill and an oversize seesaw helps kids learn about levers.
