For example:
Cat Hair
Dog Hair
Colored-Treated Hair
In class, we also got to view different types of fibers, including cotton, silk, and wool.
For example:
Cotton - cotton is very smooth, having come from a plant.
Wool - having come from an animal, wool is lined with tiny ridges.
I thought it was extremely interesting to observe the different types of hair under the microscope; it was clear that they were all different! For example, the color-treated hair was the dyed color until you hit the root, where you could see its original color poking through the dye as new hair grew in. Dog and cat hair was shaggier than the human hairs, if only a little bit. I learned a lot from this lab, because beforehand I didn't think that hair and fiber analysis could be very helpful to a forensic case, but this lab taught me otherwise once I got to see the difference between all the different types of hairs and fibers!
a nice, brief, concise, and elaborate post. although, maybe you could add a small procedure to explain how we did observed the hairs.
ReplyDeleteIt is very to-the-point and easy to follow. It's unfortunate that the pictures don't show up! Mine doesn't either for some reason... If you could include the different qualities of human hair according to its races.
ReplyDeleteI like how you placed everything, its very straight forward and to the point. Maybe you should go and include the different qualities about hair.
