Though the use of blood type in forensic investigation is not enough to prove guilt, it may aid in exonerating potential suspect. In this activity, students act as lab technicians and assist investigators by examining evidence collected at crime scene. Students first use a presumptive blood test to determine if a substance on a stained piece of cloth may be blood, and then determine the blood type of a sample collected at the scene. Students then compare their results to those of samples provided from two suspects. Kit contains enough materials for 10 groups. Teacher's Manual and Student Study Guide copymasters are included. Kit includes: • 40 Blood typing trays • 10 Cotton swabs • 1 Cloth • 1 bottle 70% ethanol • 1 bottle Blood detection reagent #1 • 1 bottle Blood detection reagent #2 • 4 Simulated blood samples: Victim, Suspect #1, Suspect #2, Crime Scene Evidence • 1 bottle Simulated anti-A serum • 1 bottle Simulated anti-B serum • 1 bottle Simulated anti-Rh serum

Blood typing is a method of classifying blood based on the presence or absence of specific proteins (erythrocytes), on the surface of red blood cells. Blood type, an inherited characteristic, is valuable to know in that it affects medical procedures, such as surgery and transfusions, paternity testing, as well as serving as evidence in criminal investigations. Determining blood type can help provide supporting evidence or eliminate a possible suspect's involvement in crime. This activity includes a teachers manual and a student guide and analysis copy-masters. There is enough material for 15 groups. Note: This activity uses Innovating Science Simulated Blood and is safe for classroom use. Kit Contents: • Blood typing trays • 4 Simulated blood samples: Victim, Suspect #1, Suspect #2, Crime scene • 1 set ABO/Rh blood typing anti-sera • 1 pack mixing sticks

Crime scene investigators examine the scene of possible violent crime for evidence, such as fingerprints, hair, fibre, etc. After collecting the evidence, they notice there is no visible blood. Someone sprays the area with a liquid then turns out the lights. A strange, faint glow appears in certain areas of the scene. Learn how Luminol is used in scenes like this everyday. The special Luminol formulation does not require a separate hydrogen peroxide catalyst. Simply re-hydrate and use with the simulated blood haemoglobin to show your class. This activity includes an instruction manual with suggested activities. There is enough material for several demonstrations. Kit Contents: • 1 bottle Luminol • Re-hydrating Solution • 1 bottle Luminol powder • 1 bottle simulated blood haemoglobin
