Focus Questions: Why are ecosystems, which are typically stable, recently changing so dramatically? What are humans doing to cause these changes? What are humans doing or could humans do to correct some of the damage? What could happen if we don’t act?

Goal: To investigate the above questions and to understand the importance of our environment and our Earth by studying and then teaching classmates about one of Earth’s ecosystems.

Procedure: Work in teams to research one ecosystem in detail. Organize your research and share what you learn with the class via a 10-minute lesson. Be prepared to answer questions from your classmates.Topics to be researched and included in your lesson:
  • Map showing the global location(s) of your ecosystem. Describe at least two National Parks.
  • Describe the particular abiotic (non-living) characteristics of your ecosystem (climate, etc.)
  • Food web of your ecosystem that illustrates typical predator-prey relationships.
  • Describe in detail the members of the food web and other common members of the community. What role does each member play in your ecosystem? Who are the producers, herbivores, carnivores and decomposers? Do not limit this to animals. Plants, fungi, protists and bacteria are all members.
  • Find examples in your ecosystem of symbiosis: parasitism, mutualism, and commensalism. Define these relationships and illustrate and describe at least two examples for each type of interrelationship.
