The most likely source of error in the student's investigation is:

She dropped the balls from different heights.

This is because the time it takes for an object to fall to the ground can be affected by the height from which it is dropped. If the balls were not dropped from the same height, it would lead to inconsistencies in the time measurements that are not due to the mass of the balls.
