Today we took a closer look at a type of trace/physical evidence: hair. Students microscopically viewed hair samples and learned that the root of the hair must be present on a hair sample to test for DNA; otherwise, hair can be used conditionally to connect a suspect/victim to a crime scene.
Students should download and print the attached worksheet, completing it as they view Forensic Files: Purr-fect Matc (black & white printing is fine!). This episode is available on YouTube. The completed worksheet should be submitted in class next week.
