Feather Fun with a Fan is a great way to experiment with wind.
I know people don’t usually have fans out in the middle of November, but we did the other day. I gave B a handful of feathers and let him experiment with letting go of them in front of the fan. He spent at least 20 minutes holding them in different ways or waiting for the fan to turn in order to see where he could send them flying. If you have a fan that is convenient to get out, this is a fun activity to try!
You can also use your feathers for this Falling Flowers activity.
