Get blonde and dark hairs from students or fellow teachers to represent the hairs of the killer and victim.
Mount hairs on individual slides using Permount. You can prepare one of each slide and set up microscopes for students to view or prepare a set of slides for each lab group. Label the slides.
Put the synthetic blood of blood type you determine is the killer’s in a dropper bottle labeled “killer” and the blood type you designate as the victim’s in a dropper bottle labeled “Roger Rabbit”.
Cut out UPC labels from 4 different products. Cut out an extra UPC from one of the products to represent the killer’s DNA Profile. You can have one set for the class or sets of the 3 suspects DNA Profiles (UPC’s) for each group. Keep a copy of the UPC that represents the killer for yourself. When students determine who the killer is, have them compare the DNA Profile for that suspect with the killer’s. I laminated the UPC’s so that they could be used year after year.
