In this activity we examined different types of hair and fibers under a microscope. We had to identify certain characteristics that made each type of hair or fiber unique. For instance when examining the hair we used hair from someone who had dyed their hair, Asian hair, synthetic hair, African American hair, cat hair, dog hair, and Caucasian hair. When looking at it under the microscope we had to examine the condition of the tip, the color that it was, if it curled and any other splits in the hair that would make it easy to identify. When looking at fibers we looked at cotton, silk, nylon, linen and wool. When analyzing these different fibers we can see that each one had a different look to it, for instance wool is a fabric that comes from animal hair while cotton comes from a plant and is then woven into cloth. Because of this their structure will surely look different, making them easy to identify at a real forensic crime scene.

ReplyDeleteGood job! I liked how you talked about the different types of fibers and how they all look different. Before this experiment, I had no clue that they looked different, I thought since they were all string they looked the same. :D Maybe add a few pictures to show what they look like?
very concise and elaborate. your description shows a deep understanding of the material!
