Homeostasis Learning Goals I can explain the meaning of homeostasis & dynamic equilibrium I can describe 4 examples of homeostasis in the human body I can explain how organ systems use negative feedback to maintain homeostasis I can apply and extend examples of homeostasis using graphs and diagrams

PRACTICING PREDICTING… Create a hypothesis What do you think a graph of maintaining body temperature will look like? Can you explain Using sci. language? -dynamic equilibrium -vasoconstrictioN -vasodilation

PracticE Analyzing & ApplYIng Q1. how DOES this example illustrate the general principle that "Positive feedback is useful when there is an advantage to making a rapid change.“? Q2. What would go wrong if your body used positive feedback to regulate body temperature?
