Today we had five of our alumni who are now in high school come back to put in some volunteer hours. We used that time to lower the student/coach ratio down to 5:1. That allowed us to try a more complicated lesson than we would not normally be able to attempt. We each made a magnetic module to add to a Rube Goldberg device. In the end all members of the class were able see their combined machine work successfully. Wait for the cheer at the end, it’s a good sound! Ms. Carcione started the marble on the successful run.
