Photosynthesis, Trees, and the Greenhouse Effect
In this lesson plan students will study photosynthesis and then transfer their understanding of this topic to a consideration of how trees can help reduce the negative impacts of the greenhouse effect. They will read a webpage describing the greenhouse effect, the role of carbon dioxide as a greenhouse gas, and the role of humans in exacerbating this effect. Students will also browse the website of an organization that sponsors tree planting programs and consider how these programs might help reduce or slow down the increase of the greenhouse effect. They will conclude by writing paragraphs telling younger kids about the benefits of trees and plants.
