Stained with Suspicion™ Blood Detection and Evidence Processing

Your students will determine if a substance at the crime scene is blood. They will also learn the forensic techniques involved in evidence processing.
Description

This laboratory kit introduces students to presumptive blood tests and evidence processing. During the lab, students will analyze different items to find traces of blood. They will also process a piece of evidence just as it would be processed at the actual crime scene.

As in all Lyle and Louise modules, this kit is geared to high school and undergraduate courses, and is matched to National Science Education Standards. This kit is designed for 6 labs groups (up to 30 students).
