We discovered that if you drop things they fall at the same speed even if one is heavy and the other is very light. This is because gravity pulls them to ground at the same speed.
We also discovered that things like feathers take longer to land on the ground becuase they catch some air and that slows them down.
We dropped lots of things to test this theory. We discovered it is true! Even when dropped a tiny crayon and a huge, heavy drink bottle they landed at the same time!
We had a competition to see who could make their piece of paper stay in the air for the longest time. We discovered that the greater the surface area the slower the paper fell.
Have a look at the great clips here.
