Original Prompt

Create a 2-page forensic science lab worksheet titled Fiber Analysis Lab: Natural vs Synthetic Fibers for a high school Criminal Investigations class. Students will work in lab groups and will analyze fibers using both a microscope and a burn test. The goal of the lab is to help students distinguish between natural and synthetic fibers based on their appearance and how they react to burning. Structure the worksheet with the following sections: 1. Title and Brief Background Explain that fiber...

This learning resource provides an in-depth guide for conducting a forensic lab focused on the analysis and identification of fiber evidence. It explains the significance of fiber evidence in criminal investigations, particularly due to its ease of transfer between victims and suspects, highlighting the Locard's Exchange Principle. Students will learn to differentiate between natural and synthetic fibers through microscopic observation and burn tests. The document outlines necessary materials, safety protocols, and detailed laboratory procedures, including systematic steps for analyzing fiber samples. Additionally, it encourages critical thinking with pre-lab predictions, observations, and a reflective analysis on how these methods can be utilized in forensic investigations.
