No Prep Plans Forensic Science: Chain of Custody | Evidence Tracking Investigation

Help students discover why tracking evidence is just as important as collecting it with this No Prep Forensic Science lesson for Grades 9–12. Students investigate the chain of custody, follow evidence from the crime scene through analysis and storage, identify weaknesses that could compromise a case, and design their own evidence-tracking system.

Students move beyond simply defining chain of custody by examining every handoff, documentation requirement, potential human error, and broken link that can affect evidence integrity. The culminating Evidence Tracking Investigation challenges groups to create a system that keeps evidence accounted for from collection to the courtroom.
