Forensics Case 8 - No Dumping: Using soil characteristics to link suspects to a crime scene
Activity Overview
In this activity, students measure pH, conductivity, and water absorbency of different samples of soil. They use these characteristic properties to identify soil samples. They use the physical and chemical characteristics of soil samples collected from suspects to determine whether a suspect had been at a scene of crime.
