We found an ash tree with lots of seeds on it.
Teacher found a sycamore tree with lots of helicopters on it.
These seeds fly in the wind.
Teacher can use a balloon to make a helicopter fly.

We made our own helicopters. They fly when we drop them. The smaller ones fly better than the big ones, and helicopters with paper clips fly the best.
