Fingerprinting
Our class is learning how to do fingerprinting for our crime scene. We all get our fingerprints when our mums are 16 weeks pregnant. There are three most common types of fingerprints they are Loops, Whorls, and Arches. I have 8 loops 1 arch and 1 whorl. We had to roll our fingers on an ink pad and then roll our fingers on the piece of paper. I gets real messy. We can also put some dust on a window or something and press your finger on the dust and then get a gelatin clear card and stick it on the finger/dust/window and get a roller a roll it on the gelation card. police also put a number and an arrow to make sure how to identify it and also to show what way is up and which way is down.
