Main Learning Goal: Students will demonstrate understanding that an invasive species has an impact on the biodiversity of an ecosystem. This will be accomplished by looking at how ecosystems are affected by biotic and abiotic factors as well as evaluating solutions for maintaining the biodiversity of an ecosystem.
Focus Question: Why does the government care if I bring fresh fruits and/or vegetables in from other countries? Learning Targets:
Cross Cutting Concept Ideas: Pattern- What patterns can be identified between the introduction of an invasive specie and how the natural environment changes? Cause and Effect- What effect does a non-native species have on another species in an ecosystem? Scale, Proportion, and Quantity- How does the population size of an invasive specie increase or decrease a native species chance at survival? Systems and Systems Models- How is the reintroduction of the wolves in Yellowstone an example of how a system can change? Energy and Matter- How does an invasive specie disrupt the flow of energy and matter in a bio-diverse ecosystem? Structure and function- How do non-native species interact with the ecosystem that they are introduced to? How are ecosystems dependent on the interactions of biotic and abiotic factors within? Stability and Change- What can happen to an ecosystem when a non-native species is introduced? |
