The power of trees - KS3 assembly
Discover the incredible ways trees benefit people and the planet with this assembly for secondary school students.

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.
