When ready, students could then open the pop-top, give the hovercraft a little push and watch the disc move over the surface of the tables. We talked about how this could work, and how the air coming from the balloon created a cushion between the disc and the table, a cushion that allowed the disc to "float".
As this was a fairly quick build and test, I added the wind tunnel activity into the day. Using our home-made wind tunnel and some light every day objects (foam peanuts, puff balls, cupcake cups, pipe cleaners, etc.) students were tasked with creating an object that could float slowly up the tube.
These activities were a great test of the resources in the room, as we used the fold & nest tables to quickly create stations for hot glue gun use, wind tunnel build, and hover craft testing platform. I am eager to try more station work in the weeks ahead.
