Unit 15: Gas Exchange and Excretion
Essential Question 1: How and why is gas exchange important in maintaining homeostasis?
Essential Question 2: How and why is excretion of metabolic waste important in maintaining homeostasis?
Essential Question 3: What are the structures of the human gas exchange system and their functions?
Essential Question 4: What are the structures of the human excretory system and their functions?
Homework
Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.
Richard Feynman( 1918 – 1988) an American physicist known for expanding the theory of quantum electrodynamics and particle theory.

CONTENT KNOWLEDGE OBJECTIVES
Initial Understanding:
- Discuss the role of gas exchange in plants and its necessity in maintaining homeostasis.
- Discuss the role of the respiratory system in animals and its necessity in maintaining homeostasis.
- Explore the necessity for having adaptations for maintaining osmotic balance in organisms.
Developing an Interpretation:
- Describe the process of maintaining osmotic balance and excretion in simple freshwater organisms.
- Describe the function of excretion and the maintenance of osmotic equilibrium in those animals possessing a circulatory system.
Making Connections:
- Understand the function of the human excretory system and its necessity for maintaining homeostasis.
Taking a Critical Stance:
- Compare and contrast the functioning of the respiratory systems of the animal kingdom including annelids, bony fish, mammals and humans.
