Risk Management Event Tree

The 3 files attached here compose a method to train students how to identify & show how you are managing risk.
The title & subject of "No School" was chosen to better relate to students knowledge. This has been used to teach high school level students how to use an event tree process to better understand unwanted events, how they occur & how to either prevent them or mittigate their effects!

The teaching works better when the lower level events nor mitigations are revealed before hand, but are explained after the students compete to identify them.
