Tools of Timekeeping: A Kid's Guide to the History and Science to Telling Time travels through the past and into the future to explore how humans have measured the passage of time throughout history, from ancient civilization's earliest calendars and shadow clocks to the atomic clocks of today.
Kids will track the evolution of timekeeping devices, meet the 
inventors of calendars and clocks, learn interesting facts and trivia, and work on 15 hands-on projects and activities to understand how civilization's vague abilities to track days and months has transformed over centuries into a sophisticated ability to keep time to the millionth of a second.
