A great STEM activity based on the inventor of the Ferris Wheel! His backstory is fascinating and how he came to create the Wheel interests any STEM lover! Included is a PDF with two book suggestions as well as links to videos to show about George Ferris (if the books aren't available). You can show it as a Powerpoint by itself or as a follow up to reading one of the stories.
Then, students create a Ferris Wheel using available supplies. It's bound to be a popular activity in your classroom or Library!
