Lab Activity: Who Kidnapped [Your School Mascot]? (blood typing, DNA tests)
Who Kidnapped the School Mascot? A Forensic Mystery Lab
Turn your classroom into a crime lab with this fully customizable forensic science activity! With just a few quick edits, you’ll have a personalized mystery that has students testing blood samples and analyzing DNA to uncover which of your coworkers is guilty of kidnapping the school mascot.
🔍 How it Works:
Personalize the case by adding your school mascot’s name and the names of your coworkers.
Students become forensic scientists, using blood typing and DNA testing to crack the case.
For extra fun, add coworker photos to the included “mugshot tag” for a lineup of suspicious suspects!
🧪 Easy Teacher Prep:
Create “blood samples” with milk, food coloring, and simple household liquids (vinegar for positive reactions, water for negatives).
Prep DNA strips ahead of time (or use the quick-edit version with names for less prep).
Hand students the case file and watch them investigate like real detectives.
✨ Why Teachers Love It:
Completely customizable for your school
Highly engaging—students forget they’re doing a lab!
Takes less than one class period (perfect for a fun, fast-paced day)
Great way to connect biology concepts like blood typing and DNA analysis to an exciting real-world application
Your students will be laughing, testing, and collaborating as they work to solve the crime. By the end, they’ll not only know “whodunit,” but they’ll also have sharpened their lab skills in a way they’ll never forget.
