Science KS1 / KS2: What materials are waterproof?

There are many types of materials, but only some are waterproof.

Join Dr Brain and his team of scientists as they test everyday materials, looking at their properties to see if they are suitable to stop a leaking pipe.

The team will identify and test three different everyday materials: cotton wool, paper and plastic.

But which will have the properties needed to stop the leaking pipe?

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

Teacher Notes

Pupils could test a different selection of materials to see whether or not they were waterproof.

For each material they could make predictions based on the experiment they have seen.

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.
