Why do some plants blossom only during the day? How do certain birds know when and where to migrate? Why are some people "early birds" and others "night owls"? In this easy-to-read volume, Seymour Simon examines the inner biological clocks of people, animals, and plants and explains what makes them tick. The Secret Clocks was praised by School Library Journal as "a fascinating subject, well handled through Simon's open-ended questions and try-and-see approach." Readers of all ages, from students to their teachers and parents, will be captivated by these illustrated glimpses of the internal workings of their own bodies, as well as the secret lives of fish, insects, and other living things.
