The understanding of blood spatter patterns is not a widely recognized forensic practice. Bloodstain pattern interpretation (BPI) is commonly used in murder investigations‚ but could be utilized in everything from simple assault to mass murders if the number of trained professionals increased. BPI can reveal critical information into reinventing a given crime scene.

looks for human remains‚ blood or other bodily fluids and collects samples of any that if found.

hypothesis for the Blood Spatter Lab is that if blood is dropped from a pipette from gradually increasing heights‚ the diameter of the blood drops will increase at a constant rate. The hypothesis was proved correct because in the experiment‚ the higher the height the blood was dropped from‚ the larger the diameter of the blood drop. The data collected in the experiment represents the height the blood was dropped from over the diameter of the blood drop. The data shows that the higher the blood is dropped
