Examine Crime Scene Materials to Solve a Burglary. An intriguing activity using the completely safe Simulated Blood (see left), with a twist of “whodunit”. Students attempt to solve a crime by matching the blood type of samples found at the “scene” with those of several suspects. Students can actually extract samples from crime scene fabric stained with SimulatedBlood, analyze them under the microscope, and match the blood type to one of four suspects to help determine the culprit’s identity. Includes enough materials for six setups, a teacher’s guide,and student copymaster.
