Experiments in Time With Everyday Materials
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.
