Crossing the River

Topic: Forces and magnets

This is a KS1 activity. Children in Colombia in South America are facing a dangerous journey across a raging river to get to school and then back home again. The bridge collapsed 12 years ago so the kids have to wade or swim with their school stuff above their heads as the water rushes round them. There is a ferry across the River Teutan, but most pupils can't afford to pay for it.

In this activity children will investigate the properties of materials to build a raft to cross the river (or to carry their equipment). They will measure how far different rafts will travel and look at different ways of moving them.
