Lesson idea. A fun scenario to introduce the idea of balanced forces which could be used to frame the set of related ORBIT activities if the scenario was that Nelly the Elephant had escaped from the circus and consequently found herself in a number of different situations (crossing a bridge, crossing a river on a raft, jumping from a high cliff with a parachute, finding a new home with an unsuitable floor, etc.) and needing help from the children. A sense of the ridiculous often appeals.
Teaching approach. An interactive way of exploring this activity might be to have the children in small groups(ta) building a rope/string bridge and using a model elephant to stand on it. The children could either observe what happens and then discuss it or could film it and watch in time lapse to see exactly where the movement occurs in the bridge/elephant system. The latter would assist them in considering the direction of the forces acting as they would be able to see the direction of movements very clearly. (edit)
