Forensic Science - CSI activities

Glass can link a suspect to a crime scene. If the physical properties of glass fragments found on a suspect match those from a window broken to gain entry to a building or a vehicle, then the evidence may be significant. In this unit, students study ways to measure glass thickness and the refractive index of glass samples, as well as observing mechanical fit.
