EXAM REVIEW
MR. DEGREGORIO
GLASS:
*
common solid used to make windows in homes and cars; etc.
*
made of common compounds in sand
Physical Properties of Glass:
Used to determine if the glass found at the crime scene matches the glass found to incriminate the suspect
1. Density - mass divided by volume or m/v
2. Refractive Index - how the glass bends light
3. Color
Analyzing glass fractures:
There are two types of glass fractures, concentric, which are circular breaks and radial, which are linear or lines.
You can determine which hole in the glass happened first.
I know A happened first because two radial fractures from B stopped at A.
SOIL:
*different types of earth on the ground
*made from rocks, sand, organic debris, etc.
Soil can be analyzed to link a suspect with a crime scene.
Soil can be analyzed microscopically and samples from suspect and the crime scene can be compared for evidence.
