Science Causes All Kinds of Reactions!
Students become crime scene investigators as we explore the science of busting bad guys! Fingerprints, dental records, and DNA
Forensics is the application of science to solving crimes, and scientists are getting really good at it.
DNA is what makes you unique. It’s the stuff that tells each and every one of your body’s cells what they are supposed to be and do. And although your DNA is different from that of every other person in the world—unless you have an identical twin—it’s the same in every cell that makes up your body.
Another great way to tell people apart is by fingerprints because everyone’s fingerprints are unique. This means that no two people in the world have the same fingerprints. Other ways of identifying people may change as a person gets older, but fingerprints stay the same.
Teeth are also a good way to identify people in efforts to solve crimes. Dental records can be used to identify people. Because teeth are one of the hardest substances in the human body, they are frequently well preserved. Dental x-rays or records showing fillings, the position of teeth, etc. can help forensic dentists find a match of teeth to the individual.
