DNA Forensics and Color Pigments
Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

Using Plant Pigments to Link a Suspect to a Crime
Students use chromatography to separate plant pigments collected from a fictitious crime scene and suspects. They compare the Rf values of the plant pigments to determine whether the plant pigments found on any of the suspects match the...

Crime Scene Documentation
Students become forensic investigators. In this crime scene lesson plan, students go to the science lab which is the "scene of the crime." They collect evidence such as fingerprints, "blood" evidence, chromatography, footprints, and more.
