Fingerprinting is an easy (relatively) and fun unit to do in class! It does require some supplies. The good news is that once you purchase supplies, they should last you several years if students use them responsibly.
Download this free fingerprint supply list from my TPT store.
It's worth spending the money to get quality products, because they last longer and yield better results. Be sure that when you order fingerprint pads, you get the kind that clean up with just a dry paper towel (link is in my supply list). Bad things happen (and custodians get very angry) when the ink doesn't clean up easily.
Fingerprint Practice
Fingerprint Practice
It takes a LOT of practice for students to produce clear, inked prints. This is not something you want to waste new, usable paper on! I ask the copy room for one-sided recycle paper. I also send an all-school email asking for one-sided copy paper. Many teachers have paper in their recycle bin- old handouts they don't use anymore, copy or printing mistakes, etc. If you do this, just add a reminder to NOT donate any one-sided paper with confidential information. Also, if anyone donate word searches, the students will do the word search instead of fingerprinting. It's like they can't even help themselves.
Plain Impressions
Plain Impressions
Plain impressions are the kind of print left behind at a crime scene. We make plain impressions by just touching an object.
Plain Impressions Instructions and Assignment.
On TPT, I sell an instructional slideshow that teaches students how to make plain impressions. This product contains 3 different formats of Final Plain Impression grade sheets for students to turn in their final Plain Impressions. I later use these plain impressions to make the Unknown Fingerprint Test - each student is assigned one print, and they have to use the FBI 10 cards to find out which student in class that print belongs to.
Fingerprint Classification
Fingerprint Classification
Fingerprints can be classified into 3 main groups (Loop, Arch & Whorl) OR into 8 main groups.
The 8 main fingerprint groups are:
Radial Loop
Ulnar loop
Plain Arch
Tented Arch
Plain Whorl
Central Pocket Loop Whorl
Double Loop Whorl
Seeing the pattern in the fingerprints can be difficult for students (or anyone). Using a magnifier helps a lot. I like to have students highlight the pattern in the print to show me that they can see it. If a student is really struggling, have them roll a fingerprint onto a white balloon, then blow up the balloon. This can help them see the pattern in the print, and they can outline that pattern in sharpie right on the balloon.
Print Classification Assignment
Print Classification Assignment
I have students roll their own prints onto the Print Classification Assignment, then name their own prints using the 8 main patterns.
There are two benefits of having them classify their own prints: 1. They get extra practice classifying and 2. This helps them see whether their prints are clear enough to read, and to improve their fingerprints if they are not.
