Learning Intentions

• You can define homeostasis and give an example in the body as well as in an ecosystem.

• You can explain how homeostasis unifies all living organisms but also explain how it shows diversity in living organisms.

• You can compare negative and positive feed back loops, give examples of each and explain how the impact homeostasis.

• You can describe how systems with in the body affect homeostasis and the major role of each system

Content Standards being covered:

Big Idea 2
2.25 The student can construct explanations based on scientific evidence that homeostatic mechanisms reflect continuity due to common ancestry and/or divergence due to adaptation in different environments.
2.26 The student is able to analyze data to identify phylogenetic patterns or relationships, showing that homeostatic mechanisms reflect both continuity due to common ancestry and change due to evolution in different environments.
2.27 The student is able to connect differences in the environment with the evolution of homeostatic mechanisms.
2.28 The student is able to use representations or models to analyze quantitatively and qualitatively the effects of disruptions to dynamic homeostasis in biological systems.
