Establishing a Forensics Standard
Forensics Independent Project: Timing is everythingRead: 'Timely Death', by D. P. Lyle, M. D
(you received a copy of this in class on 12/7/07)
Goal: Design an experiment to demonstrate how to precisely date decay of a material or substance.
You are a forensic investigator doing basic research. Your assignment: Design a structured experiment with common materials or substances that will allow you to develop a physiologic timeline and standard.
Example: An apple, when peeled, turns brown due to the process of oxidation. Similarly, a nail, when exposed to moisture, will rust. How long will it take for an oxidation reaction to occur? What factors will influence this change? Can you construct a timeline to track such a change? Your group will become an expert in that item. - Within your group, come up with an item or substance that will show short term (ideally, no longer than a few days), demonstrable decay in stages.
- Develop a procedure to test this process out.
- List your controls, dependent and independent variables.
- Your group will be doing this procedure and presenting your results to the class.
Presentations by all groups will be on Wednesday, December 19th.
