This Blood Spatter: Bloodstain Analysis Experiments activity & project also includes:

It may be gruesome but somebody's got to do it! Young forensic scientists get a feel for what the job entails as they study blood spatter in seven experimental activites. They examine how spatter can be changed by release height, surface, direction, angle of impact, force, and origin. For each factor, they follow a lab sheet and fill out a table to draw conclusions. An eighth activity has students examining an online crime scene, however this is not provided and may need supplementary materials if you use it.
