The Secret Service has arrested suspects accused of counterfeiting coins from 1915 valued at $50,000 each. The students act as a forensic scientist to investigate the crime scene and examine the evidence. Students learn about electrons and chemical reactions to recreate the methods used to make the coins and prepare evidence for the court case.
