Title: Bloodstain Pattern Doesn't Lie......
Description: Students will formulate a hypothesis about the relationship (linear, direct, indirect, etc.) between the distance a drop of blood falls and the diameter of the splatter it makes. To test their hypothesis, the students will work collaboratively to make blood droplets, on paper, from different heights. After graphing droplet diameter and height using a spreadsheet program, individual students will evaluate their hypothesis. Students will use their graphed data to: 1) write an equation for the mathematical relationship of droplet diameter and height. 2) interpolate the height from which a blood droplet made by someone else was dropped. The students will compare data from different groups to determine possible sources for differences.

Blood Drop Lab Activity
Overview:
This podcast was created to outline a lab activity on the analysis of blood droplets that can be utilized in the forensic science classroom.  The video contains footage from a high school classroom.  Students perform drops at varying heights to first determine the effect height has on the diameter of the drops.  The teacher then demonstrates the correct lab technique for performing drops at set angles. After performing their drops, the student then use the mathematical relationship between the height and width measurements to determine the actual angle of impact.
