Whirligigs

What in the world is a whirligig, you ask? A whirligig is the hottest new toy on the market that spins as it falls! However, the design team came to our 5th grade class to ask us one favor...How can we get the whirligig to have better hang time? As a class, we decided that in order to create a fair test, we can only change one variable at a time in order to figure out how to make our whirligig hang in the air longer.

Above is Shaterria and Lupita testing the whirligigs with different types of paper.
