Clean Air Superheroes: Our Mission for a Greener School

A clear and engaging primary school assembly about clean air, air pollution and active travel. This assembly helps pupils understand how air pollution affects our lungs, our school community and the environment, while giving them simple actions they can take straight away.

Children learn what air pollution is, where it comes from and why school gates can become busy pollution hotspots. The superhero theme keeps the topic child-friendly and empowering, showing pupils that walking, cycling, scooting, choosing quieter streets and asking adults to switch off engines can all make a real difference.
