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?
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?
