What is Forensic Science?
Is it this? Some, but

It is the application of science to law!
Crime Scenes & Evidence Collection
Crime scenes are about careful observations.
Evidence collection is about details. All evidence must be collected in specific manners and carefully logged.
Physical Evidence
All of these are pieces of physical evidence, as well as much more.
Physical Properties
Same properties as in any other class: Mass, density, temperature, refractive
index, color phase, etc.
Describe the physical properties of gack- seen on the left.
Organic Analysis
Analysis based on organic properties:
Inorganic Analysis
Analysis based on inorganic properties:

Q14
Kennedy’s brain

Microscopy
From old to new, all can still be used today. The one on the right is a comparison microscope.
Hair, Fibers & Paint
These small pieces of evidence can be keys to the crime.
Hair Fibers close-up Paint layers
FingerprintingEveryone has unique fingerprints. These can be the keys to solving a crime. The trick becomes trying to find and develop them.

DNA- the irrefutable proof DNA typing has many different uses.
Arson & Explosions
What can assist in arson? How do we analyze an explosion?
Firearms, Tool Marks & Impressions
A lot of comparisons go into the anaylaysis of these.
Document & Voice Analysis
These are tools used for comparison.
Case Analysis
Each of you will do a case analysis of a different case.
True Crime Readings Each of you will read a true crime
novel and present to the class.
Expectations:
Respect
Learn and work
But still Fun
