This class went amazingly well. All of the kids understood the concepts really well and were quick to finish their projects. The sweeper is a small car with a few blades in front of it that clear its route as it moves. The car is entirely mechanical, and so this class was a great exercise in gear mechanics. Each week our projects get slightly more complex as we would like our students to feel excited by the challenge, and I was happy to see everyone getting the concepts well and finishing the in-class projects in time. I look forward to seeing the same excitement and competence next week.
