We then threw them up into the air to see what the wind would do with them. Some of the planes flew only a short distance. Others flew a very long distance. But, the interesting ones flew in all sorts of directions. Those planes where trapped in wind currents.
Butterflies always float to the ground very slowly when they land.
The air resistance allows them to do this because of the shapes of their bodies and their large wing spans. We stood on our chairs and dropped several objects to the floor. Our handwriting papers floated to the ground very slowly like a parachutes. They were meeting air resistance. We found out that air will resist objects traveling through it.
