Subject: Exploring and investigating time

Materials included in the Measuring Time unit kit.

In the first part of this unit, students explore
the use of natural phenomena, such as the phases of the moon, to keep time. In
the second section, students conduct experiments using some of the instruments
that have been used to keep time throughout the centuries. They build and
experiment with a water clock and investigate the characteristics of the
pendulum. Finally, they apply what they have learned to assemble and evaluate a
clock escapement and modify the device in order to make it more accurate. The
unit provides students with an opportunity to learn how to measure time, to
investigate machines, to explore concepts such as energy and motion, and to
learn about the science of astronomy.
