ABOUT FINGERPRINTS
Fingerprints are UniqueSome Types
Fingerprints are very different and they all have different shapes and sizes but if you look closer tiny little bumps here’s what those bumps are called:

Loops: Go forward then curve back forming something that kind of looks like a loop

Whorls: Whorls are circular finger lines that look like a snail’s shell

Arches: Are 2D bumps on your hand and there usually close to other Arches

Deltas: Are a stick person with no arms and no head on your finger you should have one

Fingerprint Patterns and Characteristics<https://www.youtube.com/watch?v=XDKzz4in7Xg> Crime Scene Investigator, Rebecca Hooks, explains the different fingerprint patterns.

During the fingerprinting sessions we learned about the fundamental principles behind the science of using fingerprints for identification. We took a fingerprint of our forefinger or thumb by simply using a pencil and a piece of scotch tape.  By taking a photo of our prepared fingerprint, we discovered that we could use an iPad to enlarge it. Very quickly we were able to identify the basic ridge patterns: “arch”, “loop” and “whorl” of our fingerprints. Next we learned more about the study of ridgeology and tried to find other ridge characteristics in our fingerprints.

TAKING OUR OWN FINGERPRINTS ( OUR RIGHT THUMB / FOREFINGER )
Polar showed us how to do this.  All we needed was a pencil and some scotch tape.
