Simple and fun Human Hair Evidence Lab for forensics! The purpose of this activity is to give students a chance to see hair under a microscope, to identify and recognize the various characteristics of human hair, and to experience the challenge of matching hair to a suspect. They will also gain a deeper understanding of why hair is class evidence, and the danger of improper use of hair evidence in court.
Included in the Human Hair Evidence Lab resource:
- Google Slide with instructions for students for completing the lab
- Student Lab Sheet
- Student Lab Sheet Key
- Teacher Key Template
- Teaching Guide with easy to follow instructions
This activity has three parts:
- Students start with analyzing their own hair
- Then work to identify an unknown hair from a sample of suspects
- As an extension activity, watch a 20 minute video clip (free on YouTube) about the faulty use of hair evidence. Students answer questions as they watch
Materials Needed to complete the lab:
- Microscope slides
- Clear tape for securing the hairs on the slides
- Sandwich bags – at least one per student plus a few more
- Gallon sized bags – one per group
- Paper for making evidence bindles
