The teacher shared a demonstration with the same students. She begin by standing on a desk, holding a book and an open piece of

paper in the air, away from her body.. She asked her students: "Which will hit the ground first if I drop them?" Based on the previous data, the students answered that they would hit the ground at the same time. When she dropped them, the book hit the ground first. Next she crumpled up the paper and repeated the experiment.
Elaborate on the two paper drops. Was there different results? Why?

A) No. In both cases, the book dropped faster than the paper because it had so much more mass.
B) Yes. The crumpled paper dropped at the same rate as the book; the flat sheet did not due to air resistance.
C) In both cases the paper fell at the same rate because in both cases the air resistance and the masses were the same.
D) Yes there was a difference in the rate at which the papers fell. The crumpled paper had the same air resistance as the book so they fell at the same rate.
