Science KS1 / KS2: Testing the strength of different materials

All solids have different structures, which means that some are stronger than others.

Dr Brain, and his Mad Lab team, identify two solid materials (wood and polystyrene) and test their strength to see which is more suitable for sitting down on.

This short film is from the BBC series, Ultimate Brain: Mad Lab.

Teacher Notes

Pupils could identify everyday materials then suggest other everyday materials which would be suitable for sitting on.

They could carry out experiments, testing the suitability of a variety of other materials for a particular use. E.g. materials for a parachute, walking stick or drinking straw.

Pupils could give reasons, based on evidence from fair tests, for the particular uses of everyday materials, including metals, wood and plastic.

Curriculum Notes

These short films are suitable for teaching science at Key Stage 1 and 2 in England, Wales and Northern Ireland, and First and Second Level in Scotland.
