This lesson has turned out to be one the kids really enjoy. The bumper car introduces the kids to many new concepts, a detachable cover to hide the hub, using the touch sensor to change directions, introduces them to new coding blocks like the "repeat until" and "greater than less than", and provides an opportunity for extension where the students can make improvements to their cars and programs and bring them back to the field for more friendly competition. Like real bumper cars, there are no winners or losers, just a lot of fun and laughter.
