We leave fingerprints on everything we touch hundreds of times a day. We leave them on drinking glasses, silverware, computer keyboards, toys, door knobs, water faucets, books and more. Even though we leave them everywhere, we don’t notice them at all. At a crime scene though, these left behind prints can be very important. Even one fingerprint can solve a case.
The skin on the palms of our hands and on our fingertips are covered with a pattern of ridges. You don’t even need a microscope to see them. These ridges help us grip things. Every single person has a different pattern of ridges. Even the hands and fingers of identical twins are different. The ridges stay the same throughout a person’s life too. These facts are what make fingerprints so useful for crime scene investigators. Fingerprints don’t lie. Today, you will learn how to take other people’s fingerprints.
Maybe you would like to be a forensic detective. Forensics are scientific tests that are used to solve mysteries. A forensic scientist might work in a lab or might go out to places where crimes are committed, the crime scene. Watch this video of Jose. He uses forensic science to solve mysteries. By testing physical evidence he identifies suspects and helps bring them to justice.
Not everyone would like being a forensic scientist or a crime scene investigator. People who do this job work in good weather or bad, during the day or in the middle of the night. Because they are helping investigate crimes, they have to look at crime scenes and victims that have been hurt. However, if you like science and you like thinking through things in steps using logic, it might be the job for you. You could feel good knowing you helped put a criminal in jail or knowing you helped prove the innocence of a person. Now that you’ve watched Jose, you can really put yourself in his shoes. Get some online experience with forensics at CSI Web Adventures Rookie Training.

Nic Bishop, who also wrote Nic Bishop Spiders and Nic Bishop Frogs, has now turned his camera lens toward butterflies and moths. He continues to capture really amazing pictures of animals.

If you didn’t know it was a caterpillar you’d never guess.
