Have students scan this AR trigger with the app LAYAR on the iPad. It will take them to an Avatar video made in Tellagami which asks them to compare and contrast(in a Venn diagram) the types of crimes that people got the death penalty for in the 1700’s and the types of crimes that people get the death penalty for today. I used this in a forensics class as part of a unit about criminal law. Perhaps you could use it in your own learning environment.
