 This resource includes a simple explanation for teachers or older pupils of the forces acing on an elephant standing still on a rope bridge followed by a simple question sheet for presentation to pupils.
-An interactive method of exploring this activity might be to have the children build a rope/string bridge and use 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 movement very clearly.
