Fiber Identification

Lab sheets for three different crime scene investigation activities are tucked into this resource. In the first activity, inquisitors examine a variety of fibers, including the fiber found at "the crime scene," under ultraviolet light. In the second, they hold each near a flame to observe the reaction. In the third, they scrutinize the structure of each beneath microscope lenses. Consider assigning these exercises to early science learners as practice observing safety guidelines or as part of a forensics unit.
