Learn how forensic scientists utilize blood spatter evidence found at a crime scene. With this kit, you and your students determine the angle of impact and point of origin of a simulated blood spatter from a crime scene. The simulated blood supplied with the kit is nontoxic, nonstaining, and looks and dries just like the real thing. This multidisciplinary kit is a great way to tie geometry, physics, and biology into one intriguing activity.
