This activity is designed to allow students to see how an organism, population, community and ecosystem are all connected and build upon each other. Students make a graphic organizer with overlapping pieces in which they list definitions, and illustrate examples of each vocabulary term. This activity allows students to apply the facts to a situation by choosing their own organism and researching its' ecosystem and surrounding community. This activity also includes extension activities for students to complete after they finish their graphic organizer. I have used this activity for the past five years with my 5th graders and they love it!
