Dr. Thompson then agrees to teach the lesson on Day 7 in which he revisits the bungee jumping task, but changes the quantity on the vertical axis from distance from the ground to distance from the bridge. 

Day 7 clip 2: Exploring Distance From Bridge as a Function of Time

In the clip shown here, Ms. Coombs works one-on-one with a student who is trying to use the finger tool to show the relationship of the bungee jumper's distance from the bridge as a function of time. What you see here is two minutes of a nine-minute exchange where Ms. Coombs encourages the student to think about relative changes. This exchange occurs as Dr. Thompson is working with the rest of the class.
