 The Rogue Penny Lab
Crime Scene Movie Project
You may work alone, or in a group up to 4 people. 
1)Brainstorm a storyboard depicting a crime being committed
2) Design your own working crime scene, and show how it would be processed based on your modus operandi
3) Demonstrate the seven "S"'s of a crime scene
4) Include ID and collection/preservation of evidence.  EX: Blood Spatter, Hair, Fiber, Toxicology, Fingerprints, Graphology, profiling/stalking.
Triangulation Lab

Quarter 2 ProjectPick a case and explain how forensics was used inthis case to convict the petpetrator.

1) Biographical info in the person
2) Synopsis of the crime.
3) Explain what forensics was used and how it was used to find the person guilty.

Glass Lab

Discussion section:  Explain your fracture pattern with your method of fracturing ( 1) hammer and nail or just hammer.  2) iROCK  3) Drop from measured height ).

On your attached pictures (Pre and post fx as well as microscopy pictures) label radial and concentric fractures.  Note which occurred first and WHY!

Compare your results with your method of fracturing to your lab partners and their method of fracturing ... # of attempts, height, types of patterns noted ETC.

Before and after pictures of each type of glass drop.
a) Hammer (and nail)
b) the ROCK (iRock)
c) drop (note height dropped from)

Explain how many times it took to fracture the glass.  Describe the fracture patterns on each picture.

Types of glass - BREAKING Glass/ Fracture Pattern Analysis LAB experiment

2) cuticle pattern - rip from tip end after dry in nail polish on slide,
3) follicular tag on forcefully removed hair.
