Exploration 1 Among your group members, discuss what variables could influence the
period of a pendulum. In the space below, list three or four variables your group agrees
upon, along with possible reasons for your choosing those variables. Discuss your list with
your TA before continuing.

Exploration 2 Explain how you will determine if a variable affects the period of the
pendulum. Suppose, for example that you are testing to see if the mass of the bob affects the
period. How would you set up the experiment? What would have to be kept constant? What
would be allowed to change? How many masses would you need to test? If the mass does
affect the period, would it be possible to determine a mathematical relationship between the
mass and the period?
Exploration 3 How would you measure the period? Would there be uncertainty in the
measurement of the period? How could you minimize that uncertainty?
