CSImsa @ Chicago – Wednesday: Tie Dyes
The crime scene team began analyzing a promising new lead today by testing oil samples found on the driveway at the crime scene and comparing them with oil samples from suspects’ driveways. Students discovered the uses for the science of chromatography by watching how different colors separate, and using that information to match the crime scene oil with a likely culprit.
Our forensic scientists are developing a clearer picture of the case, and feel close to a breakthrough!
Ask your student:
What is chromatography used for? (separating materials)
