Blood typing is a method of classifying blood based on the presence or absence of specific proteins, called antigens, on the surface of red blood cells. Blood type, an inherited characteristic, is valuable to know as it affects medical procedures, such as surgery and transfusions, and paternity testing, as well as serving as evidence in criminal investigations. Determining the blood type of a suspect in a crime can help provide supporting evidence that they are guilty, or eliminate them as a possibility. In this activity, students will determine the blood type of simulated blood samples collected from a crime scene, as well as from two suspects, to determine the likelihood of the suspects’ involvement in the crime. Kit contains an Instruction Manual and enough materials for 2 groups.
