The latest exciting addition to our popular series of Crime Scene: Forensic Investigation Kits places your students in the role of forensic chemists assigned the task of determining the guilt or innocence of individuals accused of distributing an illegal substance. Evidence to be examined includes simulated paper money, simulated urine samples, fingerprints, and handwriting samples of all suspects. Paper chromatography determines if the substances contain an illicit drug. Sufficient material is provided for at least 3 classes of 24 students working in pairs. The manual, which includes all necessary instructions and background information, may be copied as many times as needed.
