Synopsis
Because time is such an important part of our lives, we hardly ever take a minute to think about it. Now kids can investigate all the wonders of time with dozens of experiments--all of which use easy-to-find supplies and materials. They'll learn how to tell time using the sun, moon, and stars. They'll make and use their own hourglass, candle timekeeper, and water clock, and they'll discover how clocks and watches work. Fun-filled explorations help explain the principles behind the pendulums in grandfather clocks, the gears that turn a clock's hands, and the motors that run electric clocks. Other investigations include making a model of the International Date Line, drawing a star map, making a cereal box planetarium, and more. Fascinating facts are included to answer such questions as why clocks count to twelve, where the word "watch" comes from, why daylight savings time is observed, how scientists can date fossils, and whether or not time travel might be possible. One look at the dozens of creative experiments contained here, and kids won't want to wait to start exploring the secrets of time. Sterling 96 pages, 95 b/w illus., 5 3/8 x 8 1/4.
