Students learn that fingerprints are even more unique than DNA and use the Fingerprint Powder Method to dust for prints in a mock crime scene and analyze them to identify potential suspects.  

Students use paper chromatography to separate ink found at the crime scene into components based on solubility and then compare results to the composition of known ink.

In the final activity of the day, students practice all the forensic techniques they have learned during the week to analyze a mock crime scene. Students collect and examine trace evidence including glass, hair and fibers and collect prints.
