Learn animal hair evidence! This resource is designed to teach the basics of animal hair identification. Students will review the structure of hair, learn the three common cuticle patterns, and the five most common medulla patterns. This gives them the vocabulary to describe and differentiate between the hairs of cats, dogs, deer, rodents and rabbits.

The Animal Hair Lab guides students to observe actual slides of these same five animals, plus any additional animal hair samples your students bring to class! The Lab also includes an ‘Unknown’ hair sample that students must identify.

While not absolutely necessary, it is assumed that students have already been introduced to human hair as evidence, and are familiar with the basics of human hair in order to compare it to animal hair. Check out the Human Hair Evidence resource if you need a way to teach the subject!

  • Google Slide set for taking notes and instructions for the Lab
  • Student Notes Sheet
  • Key for Notes Sheet
  • Student Lab Sheet
  • Google Form Review – 10 multiple choice questions
  • Teaching Guide with complete instructions for setting up the lab, along with time savers and ideas to make the lesson easier on you!
