In this lesson, we are going to introduce the students to the science behind Crime Scene Investigation (CSI). We are going to roleplay with the students impostering ourselves as crime scene investigator. The lesson is divided into 3 parts: 1. Fingerprints; 2. Identifying Unknown Substances; 3. Genetic Analysis of DNA. According to the time limits of your own, you can choose either part 1 or part 2 to conduct first, but make sure get to part 3. After each part, the students should come up with their idea of who the suspect is, part 1 and part 2 will supposedly produce contradictory results but part 3 will be the definite prove of guilty.
