Pendulum-Lab

=Integrated Science - Pendulum Lab=

Teacher: Mrs. Claire Voelker

**1. Opener: Respond to this prompt in your notebook.**
What do you think? Observe the pendulum at the front of the class. D oes the length of the string, the mass of the pendulum bob, or the angle of the swing affect the motion of the pendulum?. Think about each variable and describe how it may affect a pendulum in motion.

**2. Now Experiment and Record Observations**
Play with one or two pendulums and discover how the period of a simple pendulum depends on the length of the string, the mass of the pendulum bob, and the amplitude of the swing. It's easy to measure the period using the photogate timer.
