What is Systems Thinking• "A discipline for
seeing wholes...a framework for seeing interrelationships rather than things, for seeing patterns rather than static snapshots"
-Peter Senge
1. A perspective on reality
2. A set of tools
3. A new vocabulary

The Coming Anarchy
1. Team up in pairs and find one causal loop of 4 or more elements
• Attribute S’s and O’s to the links and record reasoning on the worksheet
2. Get together with another pair and explain loops to each other; decide on one loop and draw it on paper
3. Each group of 4 will present loop to class4. Discussion: Is Kaplan’s vision the state of
human kind? Where can we intervene?
