Tried something new today, based heavily off of labs from Frank and Kelly, which I understand is important in the unbalanced forces model. You need a motion detector, a dynamics cart, a bunch of masses, a spring scale, and some room to run. The result I liked best was seeing position-time graphs like these kids got. Did you see that? Check it:
We struggled with one detail, however: pulling with constant force. How can I get the kids to consistently pull with a constant force? We were just pulling and watching the spring scale.
This lab still needs some work from me but it was a great start, especially for the fourth Monday of summer school.
