Homeostasis
Big Ideas from this unit
Organisms have strict limits on the internal conditions that they can tolerate.
Systems that maintain homeostasis rely on feedback mechanisms.
Environmental factors can affect homeostasis.

From the curriculum:
1. Assess, on the basis of findings from a case study, the effects on the human body of taking chemical substances to enhance performance or improve health (e.g., the risks and benefits of taking large quantities of vitamins or amino acids; the effects on the human body of substances that people use to cope with stress)
2. Evaluate, on the basis of research, some of the human health issues that arise from the impact of human activities on the environment (e.g., the effects of synthetic estrogen compounds released into our water systems; the effects of leaching of compounds from plastic products into soil and water)
What is the impact on the human body of certain chemical substances or environmental factors?
