Day 2.4

Mathematics – Direct proportion is going so much better this year. I think the hands on stuff at the beginning helped a lot. Today we talked about DP equations, and we arrived there much more obviously than in years past.

Physics – Energy unit day 1! Motivated the need for a non-force approach (thanks Ravi Jain) to kinematics, and wrestled with the words work and energy. Did a little investigation involving the forces required to pull carts up ramps. Though I did the same investigation last year, this year it felt much more conceptually grounded. Good so far!
