We learned a lot about gravity today.
We learned that everything is pulled to earth by gravity.
A ball of paper will fall faster than a page of paper regardless of weight because of air resistance.
A feather will fall more slowly than a hammer (though not if you are on the moon where there is no air resistance at all)
Two bottles of water will fall at exactly the same time even if one is a full bottle of water and the other bottle is empty!
