Our class explored the various jobs of Forensic Scientists and Crime Scene investigators. They put their minds together to track down clues, analyze witness statements, test unknown liquids, test (fake) blood for coagulants, distinguishing between human and animal hair under a microscope (thanks for the hair donation Mia) and raising fingerprint patterns using Super Glue. The week reached an apex when Fairmont State University's Forensic Science Honorary, Alpha Phi Sigma, set up a Crime Scene in the library and walked the girls through a proper investigation.
Students listening to the FSU Crime Scene Investigators walk through the crime scene.
A murder has happened in the library! The Girl's STEM class broke into CSI teams and worked together to solve the crime. Working with the Forensic Science Honorary from Fairmont State University, students learned to secure the site, document evidence, create a timeline, and other important jobs that Forensic Investigators perform to help detectives solve crimes.
Students dabbled in different types of testing in crime investigation. They looked at human and animal hairs under a microscope, tested an unknown liquid for PH levels, tested (fake) blood for coagulation, and read DNA results to follow the evidence to name the suspect. (Blood is made from milk and food coloring and is safe for students to handle without gloves.)
