Telling time, marking time, passing time, wasting time, having the time of your life -- it's so much a part of life we hardly take the time to notice. Close to 40 simple experiments and games let kids find out just how fascinating our adventures with time can be. Start them off by drawing their own personal time line of important events in their life. Then try to guess how long a minute lasts. Show them how to tell time by the moon, sun, and stars by making a lunar calendar, sun dial, and cereal box planetarium. They'll see how to use the sky as a compass if they ever get lost in a forest at night. And they'll make a simple mechanical clock that really works. Then they'll find ont the inner workings of clocks and watches available today, including coin battery watches, quartz crystals, and digitals, as well as atomic and radioactive clocks that measure time in millionths of a second and near-perfect accuracy.
