The Elephant on the Bridge

This resource may not be final.

She's standing still but there are still forces on her - find out what they are.

Lesson idea. A fun scenario to introduce the idea of balanced forces.

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.
