Determine Whether a Crime with Injuries Occurred
- Grade Level 10-College
- Links to a real world scenario
Your students will determine if a substance at the crime scene is blood. They will also learn the forensic techniques involved in evidence processing.
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.
Supplies are included for up to 30 students working in six groups. 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.
Materials Included:
Hydrogen peroxide
Phenolphthalein solution
Cotton swabs
Positive controls and presumptive test cards
Carpet scraps
