Record the types of fingerprints from those in your group.

Name	Fingerprint 1 (Thumb)	Fingerprint 2 (index finger)
Khaylanie	loop	loop
Janel	whorl	whorl

Conclusion Questions:  

The kind of finger print I have is loop and Janel had a whorl.  People do not all ways have the same finger print because everyone is different but some finger prints can be the same. In the group we did not really have any common types of fingerprints because there were only two of us. 

Do people always have the same type of fingerprint on their thumb and index finger?

Conclusion Questions:

My results didn't come out right  so I don't really have anything to say about the finger prints. To improve my results next time I would try and be more careful with the materials, But other then that I don't really know what I did wrong. Finger prints are really useful because People can touch anything that is inside or outside and anything that is around them so they are really useful for crimes and other mystery.
