Use measurement, data collection and problem solving with the pendulum to understand periodic motion, elapsed time, and arcs.
Essential Question: What determines the period of a pendulum?
Recommended Level: 5-8
Time: Approximately 50 minutes
Purpose: To introduce the concept of periodic motion. To discover that the period of a pendulum is dependent on the length of the pendulum and independent of the weight (mass) of the bob and nearly independent of the arc swing.
