Measure the angle of impact, , of the drops of simulated blood that made spatter marks on the walls, as follows. In another effort, Attingers team has published back-spatter patterns of human blood produced in the lab by gunshot (figure 3), with rigorous control of the firearms and ammunition used and the physical arrangement (Data in Brief 22 269); and a second set of blood patterns produced by blunt instruments (Data in Brief 18 648). A person must be trained in science and forensic investigation to become a blood spatter.

In addition, the reference card format will allow special education students (and other students with learning challenges) to focus on the lesson and avoids possible frustration at trying to keep up with the class notes. I developed this geocaching activity for use with the CSI summer camp program at the Smithsonian in DC. Traditionally practitioners of blood-pattern analysis trace a straight-line from the stain at the impact angle to reveal where the blood originated. an online company for use with Terms and Definitions Accompanying Drop A small blood drop produced as a by-product of drop formation. Finally, the team found the number of resulting stains, their areas, impact angles and distribution with respect to distance (figure 2). and DNA. This should result in a spatter pattern on the paper.

Blood Stain Pattern Analysis (BSPA) is a systematic approach to evaluating the origin and mechanics involved in the creation of a bloodstain. Blood Stain Worksheets - K12 Workbook It is important to note that the term "Velocity" does not measure the speed at which the blood is traveling, but rather is used to describe or measure amount of force applied to the blood, to cause it to spatter. I printed several sets of this worksheet on card stock and laminated them to keep them for future classes.
