Step 1--Examine Prior Knowledge
The two columns below illustrate the parallel jobsto be completed in Step 1. You do not need to conduct any research to do this step. Use your current knowledge and the information from the scenario to fill in the lines provided. In the space provided in the first column, list what you know about Yellowstone National Park fires. Then look at the Earth System Diagram in the second column. Notice how the arrows go to and from the event and spheres. These arrows indicate that the cause and effect relationships go both from the event to the spheres and from the spheres to the event (Image of a gold double-sided arrow.). While thinking about these relationships, list your ideas about how the event--wildland fires-- could possibly impact the four spheres that make up the Yellowstone National Park ecosystem.

List prior knowledge about Yellowstone National Park fires.










List prior Earth system science knowledge regarding wildland fires.
