Science KS1 / KS2: How long does it take rubbish to rot?

With the Mad Lab full of rubbish, Dr Brain takes the opportunity to teach his assistants all about where rubbish goes and how long each type of rubbish will take to rot away.

Using his 'rot-o-matic' time capsule, Dr Brain and his team make surprising discoveries about different materials.

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

Teacher Notes

This could be used as an introduction to recycling and how materials can be melted down to be used again.

Your pupils could discuss the structure of certain materials, such as plastic, wood, metal etc. and explain if they think each would take a long time to rot away or not.

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.
