As part of my unit DNA: The Good, The Bad, and the Ugly — I am having my students research court cases in which DNA evidence played a significant role. Have students scan this AR trigger with the APP Layar, it will take them to a Tellagami in which I ask them to identify five people who are significant to the DNA case/trial they are studying. I used this in my Forensics class, perhaps you could use it in your own learning environment.
