W I N D! Boy did we have fun exploring wind! Earlier in the summer I had seen a wind tunnel on Instagram and made it for the STEM camp that I run.
To be honest, I had a difficult time finding some of the items the person who posted the directions listed so I made my own out of the materials that I could find. In case you want to make one, I used two large sheets of poster sized transparency paper that I got from Michaels. It was located in the back near the poster boards. (I say this only because I went to seven different stores to find something that could work! It was like the heaven’s had opened up once I finally located this transparent poster board!) I taped the two pieces together using packing tape and used large 12″ sewing rings to create the cylinder shape.
Once in the classroom, I used our hollow blocks to create the wind tunnel. The box fan had to be off of the floor to work (so that air could flow). The other blocks on top kind of directed the flow of air into the tunnel. Once set up, it was a HUGE hit. We used balloons, scarves, and coffee filter parachutes to fly up and out of the wind tunnel!
We also used a fan to observe how air flows.
After some free exploration of wind and a few picture books, we completed a science experiment.
For this activity students were given a basket full of objects, a straw, a recording page, measuring tape, and math cubes. To complete the science experiment students placed their items on the floor and blew as HARD as they could through the straw to see how far they could make their object move.
Then, they used their measuring tools to determine how far the “wind” blew each object.
They really loved exploring wind through these hands-on explorations and especially loved experimenting with how powerful wind is and can be. This was the perfect segue into learning about extreme weather! Stay tuned for the next blog in this series all about extreme weather!
