Pendulum Clock Coloring Page

Christiaan Huygens was a Dutch scientist who built the first pendulum clock in 1656. He took an idea Galileo had studied, that a swinging weight takes the same time for each swing, and used it to keep the clock ticking at an even pace. Older clocks could lose about 15 minutes a day, and his pendulum clock lost only around 15 seconds.

Tall pendulum clocks like the one in the picture are often called grandfather clocks. That name comes from a song written in 1876 about a clock that had belonged to the singer's grandfather, and it stuck.
