11. When performing a dissection in class, which of the following procedures is incorrect?

12. A student is conducting an experiment using a ball that is attached to the end of a string on a pendulum. The student pulls the ball back so that it is at an angle to its resting position. As the student releases the ball, it swings forward and backward. The student measures the time it takes the ball to make one complete period. A period is defined as the time it takes the ball to swing forward and back again to its starting position. This is repeated using different string lengths.
