pinwheels

WAL about rotational symmetry. Pinwheels We made pinwheels to show that when you turn them they look the same. What we found out. Here is what we found out. If you make a small pinwheel it spins faster. A big pinwheel got stuck on the handle. It was too floppy. If you put a fan in front of the pinwheel it spins faster. If you use a bead for a spacer the pinwheel won’t get stuck on the handle.
