Investigating Factors of Impact on Populations within Ecosystems

This is one lesson within a 7th grade unit on interdependence, and could extend up to 2-3 days if extension activities are included. This lesson focuses on learning about limiting factors, understanding the basics regarding the three types of ecosystems in Florida, and how the introduction of non-native species can impact an ecosystem. Students will gain knowledge to help them learn to be proactive in conserving the resources of land, fresh water and marine ecosystems.

As a prelude to later sequential learning, predator and prey graphical representations will be created and analyzed (this will also address common misconceptions) and lay a foundation to introduce density independent and density dependent factors, which are explored further at higher grade levels.
