Check out ancient Chinese technological innovations, taking in the technology of looms, plows, iron casting and more. Kids can turn a life-size waterwheel and watch the powerful effects. While en route, admire the sailing ship commandeered by legendary Chinese admiral Zheng He. Take the small wooden set of stairs adjacent to the ship up to the traditional Chinese medicine exhibit. There, inspect models of diseased tongues and acupuncture charts. Head back down the stairs and keep looping around the circular path to discover the astronomy exhibit, where kids can gaze upon the stars. After fulfilling their astronomical aspirations, head to the age of ancient scientific exploration. Experiment with Pascal's Triangle, Tangram puzzles, and blocks. Don't spend too much time puzzling these conundrums though, as you have three more floors to scale.
