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

ABO typing of blood left at the scene of crime can help to narrow down a list of suspects. In this experiment your students will use agglutination to identify the blood group of unknown blood samples as a step to identify a criminal. Kit Includes: instructions, control ABO simulated blood samples, unknown simulated blood samples, transfer pipettes, microtitre plate. All You Need: automatic micropipette (5-50 µL) with tips (optional). For 10 Lab Groups. Complete in 45 minutes.

High quality, non-adhesive plastic tape printed with the words 'CRIME SCENE DO NOT ENTER'. This tape is ideal for crime scene protection or other areas where forensic work needs to be carried out or is still ongoing. Simply unroll the plastic tape and it can then be tacked, stapled, wrapped or tied around suitable objects to create an instant and highly visible barrier. Dimensions (W x L): 75 mm x 100 metres.

Disposable protective suits suitable for forensics work. Size large. Sold individually.

Disposable, blue PVC over-shoes, to protect feet and help prevent cross contamination. Supplied as pack of 10.

Correctly packaged evidence is essential if reliable scientific results are to be obtained. Preserving the chain of custody is important because it maintains the integrity of the evidence. Whenever person comes in contact with piece of evidence, the contact must be documented to prove that the evidence was always accounted for and that no one tampered with it. These specially manufactured bags have many tamper-evident features, including unique bag number and printed label. These bags also have the added benefit of being leakproof.

These plain inch (15 cm) sterile dry swabs on plastic shafts, for specimen/evidence collection, come labelled for inclusion of details such as date, site and time references. Each swab comes in its own polypropylene tube for transport back to the laboratory. Sold as pack of 10 DNA-free swabs, each in its own tube.

Evidence left behind at a crime scene can identify a potential culprit. Even in this age of DNA, fingerprints and blood stains are still important at helping to identify a criminal. In this experiment, your students will solve crime by dusting for fingerprints and use fluorescent dust (not included) to search for and identify trace amounts of blood. Kit Contents: • instructions • brushes • magnifying lens • fingerprint cards • black dusting powder • fingerprint lifters All you need: alcohol, fluorescent dust, and long wave U.V. light.
