CHEM 180 - Survey of Forensic Science
MATH 060 or higher, placement in READ 090 or higher.
Survey of Forensic Science is a one quarter course designed for science and non-science majors. It focuses on the techniques used in the forensic evaluation of the physical evidence obtained from a crime. The course in intended to be a broad overview of the field of forensic science, but an emphasis is placed on the science behind the analytical techniques used in evaluating the physical evidence. Topics covered may include glass and soil analysis, drug analysis, hair, fibers, and paint analysis, fire investigation, fingerprints, firearms, tool marks, and other impression evidence, forensic toxicology, and bloodstain analysis.
