The Brown Bag STEM Challenge II- Hot Air Balloons

In this challenge, students design and fly a hot air balloon that will stay aloft the longest.  This one sounds simple, but don’t let it fool you!  It is more difficult than it sounds, so be sure to provide a little more time as students learn which shapes and designs “fly” the best.

I like to have teams of three for this project, simply because it is more involved and requires students to follow specific directions for this first round. I’m also a big fan of assigning jobs, so I prefer to divide up the work either specific to this challenge or like this.

So, what did we learn?
