This title shows children how to tell the time using the sun, moon and stars; make their own hourglass and candle timekeeper; and more. It is aimed at children age 8 to 12 years old. What makes time tick? With these dozens of experiments, budding scientists will happily pass the hours investigating all its wonders. They'll learn how to tell time using the sun, moon and stars; make their own hourglass and candle timekeeper; and, learn how clocks and watches operate. Fun-filled activities include creating a model of the International Date Line and constructing a cereal box planetarium, plus there are intriguing answers to such questions as whether we'll ever be able to travel through time.
