This wind tunnel is such a fun way for younger kids to learn about wind and introduce engineering type play. At first my son just loved putting whatever he could stuff in there to see if it would float. Some of our favorite things to put in there are colorful scarves, coffee filters, and cotton balls.
You can find the wind tunnel here.
Some good questions to guide his play were:
What happens if you put something heavy in there?
What happens if you put some thing light in there?
Where else do we feel wind?
I wonder what would move fast through the wind tunnel?
Here are some good books to encourage more talk about wind.
In a preschool setting this would be so much fun as a science or art center. For art you could decorate butterflies, paper airplanes or parachute and test them in the wind tunnel. In science this makes a great STEM learning opportunity to explore surface area, shape, and weight and how it floats through air.
