Physical Evidence Analysis

glass half full

100

this type of glass is used for lab supplies and baking ware

borosilicate

200

this type of glass is often used in stained glass, blown glass, and automobile windows

tinted 

300

this type of glass shatters into large, sharp pieces. It is commonly found in window glass, and glass drink bottles. 

soda lime

400

this type of glass fractures into cube-like pieces, and is created by treating the glass in a specific way as it's being made. 

tempered 

500

this type of glass is used in expensive drink ware called "crystal"

leaded

follow the line

100

this sub category of fracture consists of the straight line that stretches out from the impact point. 

radial

200

this sub category of fracture consists of circle-like fractures around the impact point

concentric

300

Fracture sequencing is evaluated by the interaction of the ___________ fractures. 

radial

400

If there are two impact fractures present, and the fractures from fracture B extend past fracture A, what is the order of the fractures? 

BA

500

What results from a fracture that is not connected to any other fractures apart from the original fracture? 

multiple possible sequences

soil mates

100

this concept describes the amount of red or yellow pigment in the soil sample. 

hue

200

this concept describes the brightness, or saturation, of the soil sample. 

chroma

300

this concept describes the light or dark nature of the soil sample

value

400

describe the soil with this Munsell Chart classification: 

8 / 2 10R 

very light, very dull (more grey), red-toned. 

light and dull pink.

500

describe the soil with this Munsell Color Chart: 

2 / 51  5YR

darker, highly saturated, mix of red and yellow

deep, bright, and orange

i dig soil

100

the field of science that studies soil, rocks, and crystals

geology

200

These three categories make up the texture of soil samples

silt, sand and clay

300

What is the definition of soil?

Any disintegrated surface material. 

400

Naturally occurring crystalline structure

500

These objects are combinations of minerals and crystals.

300

This scenario describes what type of fiber transfer?

"A victim is found with denim fibers, presumed to come from their attacker"

direct

400

this scenario describes what type of fiber transfer: 

"A student takes public transportation, where they collect fibers deposited from suspect earlier that day"

indirect

500

Pitting, striations, and cross-section are all an example of what type of fiber analysis.
