Students act as crime scene technicians to figure out which pieces of evidence from multiple crime scenes contain potentially useful DNA information. By detecting amylase activity, students infer the presence/absence of saliva on the evidence. Students learn why the detection of saliva is important at a crime scene, as well as how the amylase enzyme works. Materials supplied are for 6 groups of 4 students each to examine 4 different pieces of evidence.
