Why Are Trees So Important?

You may have a student or two raise their hand and ask why we should care so much about trees.

School is a perfect environment to discuss and explore the importance of trees and explain how they relate to each and every one of us.

1. Trees remove CO2 (carbon dioxide) from the atmosphere and produce oxygen, which is essential for us to breathe. According to the U.S. Department of Agriculture, “One acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen. This is enough to meet the annual needs of 18 people.”

2. Trees cool the Earth’s air and surface temperatures, helping battle climate change.

3. Trees are habitats for thousands of animal species, including birds, insects and mammals.

4. Trees’ roots hold soil in place and help fight erosion.

5. Fallen tree leaves create compost that enriches the soil.

6. Trees provide food for both animals and humans such as orange trees, maple trees and apple trees.

How to Use These Facts in the Classroom

Here are just a few fun ways you can use some of the facts above to continue branching into the world of trees:

  • Exploring plant classification? We know trees areclassified based on their physical characteristics, such as their leaves and bark, and facts 39, 44 and 48 are all perfect for introducing the differences between those characteristics.
  • Use fact 25 to introduce the concept of the ecosystem and the role trees play in it!
  • Work on understanding and comparing large numbers in math with facts 11 and 12. Why not ask students to calculate how many acorns an oak tree would drop in 10 years or how much water a sequoia tree would drink in a week?
  • Use fact 10 while teaching about space exploration in your science class. Introduce your class to the significant figures who made space travel possible and the impact that has had on our modern lives. Have students create a timeline of significant events in space exploration, highlighting the impact on scientific research and the development of new technologies.
  • Bring trees into your poetry discussions with your sixth graders by reading Mary Oliver’s “When I am Among the Trees.” Have your students work in pairs or small groups to analyze the poem and identify literary devices and their meanings. Then share fact 38 about the sandbox tree or fact 43 about the cherry trees, and direct students to write their own poems about these trees, using the devices they’ve identified.
