        SciGirls | Super Sleuths

        No matter how much someone tries to clean up after committing a crime, he or she will leave something behind and take something away from the scene. This idea is known as Locard's Exchange Principle and is why a small amount of material, known as trace evidence, is collected at a crime scene. In this activity, students will collect trace evidence (glitter) and explore some of its class (or group) characteristics, such as color, size, shape, and light reflection.
