Forensic Chemistry of Drug Detection

Everyone who ate the school cafeteria's chilli became ill. Could someone have tainted it? You are a forensic toxicologist. It is your task to determine if any of the cafeteria ingredients could have been substituted with aspirin, which appears to have been stolen from the nurse's office. You will perform a series of chemical tests, including tests on control aspirin in the lab. This activity includes a Teacher's manual, Student's guide and Analysis copy-masters. There is enough material for 15 groups.
