In the process of helping our fellow K-12 educators understand the power of the critical thinking generated by system dynamics, all of us have created various ways of telling others about what we do and how it affects students. One of the critical thinking skills I think is pivotally important in our world today is the difference between the concepts of stocks and the concept of flows.

My current example of that is the difference between the National Debt and the National deficit. What other examples of the difference between stocks and flows are useful in our world today??

Take care,
Lees
