Trees provide oxygen, which we need to breathe. But do trees breathe?

Let's perform an experiment to find out. For this project, you will need:

• Small containers of similar size (we used mason jars)
• Several types of leaves (we used leaves from three trees and two bushes)
• Warm water
• Rocks
• Timer

Follow the direction below to discover if trees breathe.

What did you discover about leaves from your experiment?
