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.
