*this slide is not intended to be shown in class
Materials: 2 sheets of paper, 1 rubber ball.
Demo: Take 2 identical sheets of paper. Show students they are identical. Crumple one sheet into a ball. Hold out the uncrumpled sheet in one hand and the crumpled one in the other. Ask students which will hit the ground first. Release both. Ask students why the crumpled sheet hit the ground first. Part 2: Take crumpled sheet in one hand and a rubber ball in the other. Show students the mass of the rubber ball is greater than the crumpled sheet. Ask them which will hit the ground first. Proceed to drop both (if sheet is crumpled sufficient, they should hit the ground simultaneously). Ask students why they hit the ground simultaneously even though the mass of the rubber ball is greater. Clickers here
