This lesson plan is about teaching students about the greenhouse effect and greenhouse gases. The teacher will begin by asking students questions about the composition of the atmosphere and gases involved in breathing. Then the teacher will give a presentation defining greenhouse gases like carbon dioxide and methane, and explaining how the greenhouse effect works to regulate temperature. Students will participate in activities where they discuss the greenhouse effect and reasons for increased greenhouse gas levels. They will also be asked to write short notes and present their answers in groups. The goal is for students to understand the importance of greenhouse gases in controlling atmospheric temperature.
