  1. Forensic Science Milbank High School

  2. Discussion • Modern Marvels: FBI Crime Lab • How did you like the lab yesterday? • Why is forensics important? • What are some areas of science that forensics encompasses?

  3. What is Forensic Science? • Forensics • Applying science to answer questions for the legal system • Crime lab • Field techs • Lab techs • Uses all areas of science • Physics • Chemistry • Biology • Geology

  4. Types of Forensic Sciences • Ballistics • Firearms, bullets • Biological applications • Serology • Blood Tests • DNA • Latent Print Examination • Fingerprints

  5. Types of Forensic Sciences • Chemistry • Identifying compounds • Toxicology • Toxic reaction • Trace evidence • Hair, fibers

  6. Ballistics • The science that deals with the motion, behavior, and effects of projectiles, especially bullets, bombs, rockets, or the like • Bullet matching • Rifling • Match marks • “Ballistic fingerprints”

  7. Serology • Medical blood test • Used to type blood (A, B, AB, O etc)

  8. Trace Evidence • Evidence that is found at a crime scene in small but measurable amounts • Hairs • Fibers • Soils • Gunshot residue

  9. DNA Analysis • Genetic Fingerprinting • Nobody has the same DNA • Usually blood, saliva, hair, or semen

  10. Forensic Chemistry • Application of chemistry to law enforcement • Analytical side of chemistry • Analyze evidence found at crime scenes

  11. Accuracy • Forensic science relies on its ability to produce accurate results • Why is accuracy and precision important? • What if a forensic scientist made a mistake?
