Product Details

Crime scenes often contain broken glass from windows, cars, vases and numerous other glass items. Matching glass pieces with other glass pieces can reveal patterns that can help explain a criminal sequence. This activity utilizes safe chemicals and simulated glass to safely teach the principles of glass density analysis, a key technique used by criminalists. The flotation technique utilized in this lab will provide the hands-on experience students need to crystallize their general understanding of density. Students will also appreciate the complexity of glass analysis in crime scene investigations.

Complete for 30 students working in pairs.
