From ancient civilization's earliest calendars and shadow clocks to GPS and the atomic clocks of today, kids will track the evolution of timekeeping devices, meet the inventors of calendars and clocks, and learn interesting facts and trivia. Hands-on projects and activities include making a shadow clock, using a protractor to create a sundial, measuring time using water, and creating your own calendar.
