Students will then break out into groups of four to conduct their own chemical analyses of four known substances and an unknown substance from the “spill.” The scenario for the exercise will be that they are acting as student investigators for a HazMat drill. After some demonstrations of various chemical tests, students will follow instructions to analyze their samples for physical properties and chemical reactivity. When necessary students will share their data with the entire group so that everyone has a complete data sheet.

Students conducted physical and chemical tests on four known chemicals and recorded the results.
After testing the "known" chemicals, junior chemists could determine which "unknown" substance was spilled in the mock HazMat drill.
