Hands-on Activity

How Healthy Is Your Ecosystem?

Fun Forces
Summary
In this activity, students will learn about the importance of balance in an ecosystem. They will simulate population changes over time. Then they will evaluate a local ecosystem and create a report that describes the ecosystem's health.
Overview
Topic: Ecosystems: Interactions, Energy, and Dynamics
Real World Science Topics:
  • An exploration of the interdependence of organisms in an ecosystem.
  • An analysis of how environmental changes can affect an organism's ability to survive and reproduce.
  • An evaluation of the health of a local ecosystem.
Objective
After completing this activity, students should be able to explain how populations in an ecosystem are sustained and kept in check by the availability of resources such as water, food, and shelter, and by predation and disease. Students in Grade 6 should be able to describe how invasive species can impact the biodiversity of a system.

Activity Difficulty Rating: 3 Each hands-on science activity has been ranked based on difficulty of set up and how difficult they are to perform. The rating scale is from 1 to 5, with 1 being the easiest and 5 being the most complicated.
