Forensics Case 11 - Ashes to Ashes: Using evaporation rate to identify an unknown liquid
Activity Overview
In this activity, students understand that evaporation rate is a characteristic property of a liquid. Based on this fact, they identify the solution and the likely accelerant in a case of arson. They compare the evaporation rates of the accelerants found with the suspects with those near the crime site.
