Ms. T.: We're going to act as a suspension bridge. Who wants to be the towers?
Jose: Me!
Ms. T.: OK, you're tall. Now who wants to be the anchorages?
Lucas and Andrew: I do!
Ms. T.: (to Jocelle) What are you representing now?
Jocelle: The weight of the cars.
Ms. T.: OK, so what happens to the cable then?
Jocelle: The cable is in tension.
Jose: The towers are in compression.
Lucas: The cable is in tension.
Andrew: The cable is in tension.
Ms. T.: How do you guys feel, the towers?
Jose: It's like I'm being weighted down and it's hard for me to stand up. It's like my knees are buckling and I'm trying to stay up.
Richard: When she pushes on it, it's like we're being pulled down to the ground like we're about to collapse.
Ms. T.: OK, what about the anchorages? What do you feel?
Lucas: Like my arms are being stretched because of the weight.
Ms. T.: (points at the cable held by Andrew) If you let go of this, what do you think would happen to the towers?
Group: They will lean, they will collapse.
Ms. T.: Why don't you try that and see?
