Subject math, science Objectives Students will be able to describe the ways in which trees benefit air quality and determine how to landscape a home with trees to decease energy use. Materials Drawing of students residence. Background Trees are much more than something pretty in your yard. In addition, trees and plants have a great impact on our air quality.
Trees act like filters.
The leaves capture particulates like dust, soot, and pollen and remove them from the air. They also remove and store carbon and reduce our need for energy. Trees act like a carbon warehouse. In the process of photosynthesis, plants remove carbon dioxide from the air and release oxygen. A healthy tree uses over 20 lbs. of carbon dioxide each year.
