Unit 1: Normal forces (Camp and Clement)

SOCS-I: I think that perhaps I am skeptical because I love the modeling materials so much, but I find it difficult to see my own students making the conceptual leaps between the different demonstrations illustrated in this unit. I really think my students need to be doing their own investigations. I of course have no alternative for dealing with the normal force misconception, but I would like to make this lesson more interactive.
