Collect Hair and Fiber Evidence at a Crime Scene | Forensic Science | Printable

What it is
This forensic science lesson focuses on collecting hair and fiber evidence at a simulated crime scene. Students learn how to properly locate, collect, handle, and preserve trace evidence using structured forensic procedures.

Why it matters
Hair and fiber evidence can provide important investigative clues, but only if it is collected carefully. This resource helps students understand why proper evidence collection matters and how small mistakes can affect reliability, analysis, and conclusions in forensic investigations.
