Trees are planet-saving superheroes!

With this assembly, KS3 students will learn why trees are essential for life on earth. They'll discover how trees fight climate change, pump out vital oxygen, support heaps of wildlife and so much more.

You can use this presentation to support your school’s tree-planting activities and inspire young people to take action to protect trees and woods.

By delivering this assembly you can earn two points on the Green Tree Schools Award.

How to claim your points

Your school can earn two points on our award when you deliver an assembly – either The Power of Trees or our KS2 assembly The Man Who Planted Trees. Points will only be awarded for one assembly.

To claim your points, tell us about your school’s assembly. Let us know when you delivered it, how your pupils responded to the key themes and if you linked it to tree planting. You can send in photos and videos too.

Email with the subject line 'KS3 assembly'.

We’ll add two points to your account after we receive your evidence (usually within two weeks).
