To improve the investigation, the best response would be:
by dropping the balls from the same height
This would ensure that the only variable affecting the results is the mass of the balls, allowing the student to more accurately study the effect of gravity on objects. Keeping the drop height constant means that any differences in the results can be attributed more directly to the different masses of the balls, rather than the height from which they are dropped.
