Problem A huge problem for Suntrust Park is keeping all of the fans safe while in the park. To ensure the safety of visitors to the Braves SunTrust Park, one task for security personnel is to to identify unknown substances to determine what they are. You are in a training program to become one of the security personnel at the new stadium, and you will be learning how to identify unknown substances. In order to become certified, and get a job at the new park, you must identify unknown substances and document how you made the identification based on their physical and chemical properties.

The substances you will identify for your certification will come from the following items. The metal is one of the following: Copper Aluminum steel The clear liquid is one of the following: Water Isopropyl alcohol 3.
