Marble Hill International School, Bronx
Summer Research Program for Science Teachers
OBJECTIVE: Students will be able to identify and describe various bloodstain and spatter patterns, and explain their importance in Forensic Serology.
How are bloodstains and spatter patterns examined?
Handouts and Blood work activity labs (Ward's Blood Spatter Analysis Kit).
Students will be given handouts of bloodstains and asked to answer the following questions.
DEVELOPMENT (Elicit Responses From Students Based on the Motivation)
Bloodstains and spatter patterns are important because they can interpret and reconstruct the events that must have occurred to have produced bleeding. Investigators examine the following:
1. Location of the blood stains and spatters.
2. Distribution of the blood stains and spatters.
3. Appearance of the blood stains and spatters.
4. Surface Texture (Porous vs. Non-Porous)
*Porous = absorbent; Non-Porous = non-absorbent
5. Direction of travel (towards what direction is the blood traveling)
6. Impact angle of bloodstains and spatters on a flat surface
7. Origin of bloodstains and spatters (point of convergence)
Students will be instructed on lab activities that provide practical understandings of the above.
