SCENARIO #2 - Donna's Pendulum Experiment In this exercise you will read the following scenario and identify the parts of the scientific method in it.
Donna has observed that her father can control the speed of their grandfather
clock by adjusting the height of the weight on the end of the pendulum. Donna
thinks that the pendulum will move faster when the weight is lowered, and
wants to test her idea. Donna gets a stopwatch and measures the time it takes
for the pendulum to swing twenty times when the weight is moved to its lowest
position. Donna begins to move the pendulum up by 1 cm and continues to
measure the time for twenty swings of the pendulum. Donna records her data.
