Understanding Cause & Effect Relationships in Ecosystems

Last week we began a study of ecosystems. Our students analyzed photos showing different population phenomena, as well as components in a food web, and identified resulting cause and effect relationships. This week students engage in some online ecosystem simulations and analyze the results. Students will be focusing on two essential questions throughout the unit:

  1. How does a system of living and non-living things operate to meet the needs of the organisms in the ecosystem?
  2. How and why do organisms interact with their environment, and what are the effects of these interactions?
