Investigate Fingerprints

What is a forensic scientist? With this science activity, you will investigate fingerprints and learn more about forensic science.

Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. One of them is by collecting fingerprints. A fingerprint is the patterning that is formed by the ridged skin on our fingertips. Fingerprints are markers of individual identity and the patterns are unique for each person. They are used in many different ways. Collected from crime scenes, fingerprints can provide crucial evidence about who committed a crime. Through the use of electronic biometric readers, fingerprints can give access to a college dining hall or even unlock your phone or computer.

This simple activity will teach you how to examine and investigate fingerprints. Have fun, STEM Warriors!
