Everyone who ate the school cafeteria’s chili became ill. Could someone have tainted the chili? You are a forensic toxicologist. It is you and your classmates’ task to determine if any of the chili ingredients from the cafeteria 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 acetylsalicylic acid, the chemical name of aspirin, in the lab. Kit contains enough material for 15 groups. Teacher’s Manual and Student Study Guide copymasters are included.
