Galileo helicopters

Aristotle believed that heavier objects would fall faster than lighter ones.
Galileo however, disagreed. He claimed that things would fall at the same time....but why are some objects, like a feather or a piece or paper different?
We have been discussing air resistance and investigating how long it takes for a 'helicopter' to fall.
Using small, medium and large paper cut out models we dropped them from a height and using stop watches, recorded our results.
Does the size of the rotor blades change the speed of a falling object?
Here are some of our results:
