1. The Pendulum A.Set up a pendulum with a photogate set to read the period. B.Start the data collection to read the period. Record the period and the length of the string. C.Adjust the string to a new length and record the new period and length. D. Repeat for 5 different trials.

2. Setting Up for Pendulum Timing 1.Hook up the Labquest to the computer and start LoggerPro. 2. Go to Experiment> Set Up Sensors> Show All Interfaces 3. Click on the picture of the Photogate and select “ Pendulum Timing”
