This lesson plan teaches 4th grade students about climate change, the greenhouse effect, carbon footprints, and ways to reduce their impact through two 45-minute sessions. In the first session, students explore the term "green space" and examine satellite images of communities to rate their level of greenness. They also identify an area near their school that could use more landscaping. In the second session, students learn the lifestyle, economic, and environmental benefits of green spaces. They work in groups to explain these benefits and create a poster. Students then evaluate areas in their community and write letters advocating for more landscaping.
