What time is it . . . and how do you know?

This fact- and photo-filled Smithsonian Penguin Young Reader will fill you in on how people first began measuring time and why knowing "when" is important.

Time is when things happen and how long they take to happen--but how long is all that? The history of telling time is the history of inventions and communication, from hour glasses to atomic clocks, from calendars to chronometers. Tick-Tock is a fun look at the many ways different people have tried to get in sync.
Gina Shaw is a writer and editor who has taught children's book writing at Hofstra University. She is the author of the Smithsonian books Curious About Orangutans, The Poop Sleuth, The Buzz on Insects, Curious About Snow, Curious About Zoo Vets, and Welcome, Bao Bao. View titles by Gina Shaw
