Practice Scenario #4: Air Pollution
To complete this practice scenario, follow the steps below. Use the resources in the right-hand column to complete
the steps as needed.

4. Debrief and see examples.
1. Listen to the radio report. While listening, create a list of elements from the story that are rising and/or falling.	Listen to the report. View a list of elements.
2. Optional: Create a stock/flow map or create a connection circle as a precursor to identifying loops. Using these strategies can help in finding feedback loops when the circular connections are not immediately obvious.	Resources Download handout – Stock/flow template View a map with some elements represented View an example of a finished map Download directions for creating a connection circle View a connection circle example View a video clip showing a connection circle being created (being developed) Download handout – Template with seven graphs Download handout – Template with ten graphs Download handout – Template without graphs Download handout – Template with elements from the story View an example of a finished connection circle
3. Create one or more causal loops from information described in the radio report. If you did step 3 above, look for loops that are embedded in your stock/flow map or connection circle.
