3. Outline for Today Review where we have been See where we are going
Work Time plan for today

4. What Have We Accomplished?
Learned how to identify the nodes and edges in a variety of networks
Worked in groups to construct economic networks
Learned how to analyze a cell phone network using computer software and manually (quiz)
Investigated the local ecology of the Tyee Campus (bunnies!)
Learned about the cycling of Carbon, Hydrogen, Oxygen, and Nitrogen through a generic ecosystem (meeting space!)
Read and took notes about the Carbon, Water, and Nitrogen cycles (work time!)

5. Pop Quiz! Brainstorm one scenario that would make this diagram true:
What are the nodes?
What are the edges?
What is cycling through the system?

6. Pop Quiz!
Scenario 1: The bunny population of the Tyee Campus is exploding! There are bunnies everywhere! What will happen to the local ecosystem? Over time, what will happen to the bunnies?
Scenario 2: It is the middle of summer and it hasn’t rained in over two months. The bunnies have moved to Angle Lake where there is lots of shade and water. What will happen to the ecosystem of the Tyee Campus?
Scenario 3: Until yesterday, there were no snakes known to live on the Tyee Campus. Snakes eat bunnies. What will happen to the ecosystem of the Tyee Campus?

7. Where Are We Going?
You have just experienced a sampling of where we are going.
When thinking about an ecosystem, you need to be able to:
Differentiate between different sized ecosystems
Identify the relationships between matter and energy cycling through an ecosystem
Create and use mathematical models to test the effects of various scenarios on an ecosystem
You will work with your group to integrate CHON cycling into what you know about the Tyee Campus ecosystem
You will present your findings to the class!
We will construct a model of the Tyee Campus ecosystem in Microsoft Excel using your class data
You will conduct stress tests of the model (quiz)

8. Work Time
You will work with your group to integrate CHON and energy cycling into what you know about the Tyee Campus ecosystem
You will present your findings to the class!
Your presentation should include:
Carbon cycling
Water cycling
Nitrogen cycling
Energy cycling
Data!
Pictures!
An explanation of what is missing!
An explanation of how the Tyee Campus ecosystem fits within the larger ecosystem of the Pacific Northwest
