This was the question driving the 8th graders learning during their study of motion. The answer was not a simple one. Students had to think deeply about forces and Newton’s laws to try to figure out why Ball E shot forward and the other balls stayed in place. This week students completed their final assessment explaining how the magnetic cannon worked. Students created videos, wrote detailed narratives, and/or created posters to share their learning. I was so impressed with the amount of effort and detail the students put into their work.
