The module provides an engaging educational experience that simulates field based decisions related to environmental health issues for two scenarios: a major flood and a chemical spill caused by a train derailment. After you read over the background information, you choose which scenario you want to complete. Then, playing the role of an environmental health professional, you answer questions about how you would address a variety of issues that you encounter during the disaster.
As you answer each question, you earn points based on the relative correctness of your decision, given three choices that are available in each situation. You also receive feedback explaining the merits or drawbacks of the possible answer answers. At the end of each scenario, you obtain your final score and can review the questions and feedback.
