This lesson plan is for a 4th grade science class trip to the Monterey Bay Aquarium. After exploring the aquarium, students will select a species and write a research paper, create a poster, or PowerPoint comparing and contrasting that species' natural habitat to its artificial habitat at the aquarium. The lesson aims to teach students about ecosystems, living and nonliving components, and physical and human characteristics of places, as outlined by relevant science and geography standards for 4th grade.
