School air pollution assemblies

Updated August 2025

We have written three air pollution assemblies, for Key Stages 1 to 3, to help inform the next generation about the impacts of air pollution.

The Key Stage 1 (KS1) assembly covers what happens when we breathe, the importance of breathing clean air and some of the sources of air pollution. It is intended as a gentle assembly or talk for Reception-age children and above.

The Key Stage 2 (KS2) assembly can also be adapted as a lesson or workshop and is a more in-depth look into what causes air pollution and what we can do about it.

The Key Stage 3 (KS3) assembly goes into further detail on the causes and sources of air pollution, and covers why it’s so important for teenagers to breathe clean air.

You can download all the assemblies and their accompanying notes below.

If you have any questions, please get in touch. And send us feedback if you present it at your school!
