Blood Evidence Activities

Blood evidence can be analyzed as either biological or physical evidence, making it a powerful specimen for teaching forensics across multiple disciplines. Using biology concepts, investigators can use blood to identify individuals by blood type and DNA.

When a suspected sample of blood is discovered at a crime scene, real world applications of chemistry such as presumptive blood testing with luminol can confirm or deny the presence of blood. And at scenes with blood spatter, the size and location of blood droplets can be analyzed using physics concepts to recreate the incidents of the science by calculating angles of incidence.

This collection of activities provides unique ways of teaching and investigating blood evidence in your classroom.
