Lesson focuses on how pendulums have been used to measure time and how
mechanical mechanism pendulum clocks operate. Students work in teams to
develop a pendulum out of everyday objects that can reliably measure time and operate at two different speeds. They will determine the materials, the optimal length of swing or size of weight to adjust speed, and then develop their designs on paper. Next, they will build and test their mechanism, compare their results with other student teams, and share observations with their class.
