First grade has been learning about different ecosystems. An ecosystem is an environment in which living (plants and animals) and nonliving things live together. Some ecosystems we studied were deserts, forests, rainforests, oceans, coral reefs, and mountains. First graders worked in groups to learn about their chosen ecosystem. We presented our findings in the form of a picture of our ecosystem. Our drawing included at least 2 plants and at least 4 animals who call that ecosystem home.
