Make Forensics Fun!

Forensic science solves crimes by applying disciplines of
science such as physics, chemistry, biology, computer science, and engineering
to analyze evidence! Bad guys may not think they have left incriminating
evidence behind, but forensic science helps to make sure that justice is

Biometric technology is a sector of the forensic sciences
and is used to identify a person based on some aspect of their individual
biology. Facial recognition software, D.N.A. profiling, iris scanning, and
fingerprinting are all examples of biometric technology! Fingerprint analysis
is one of the original biometric technologies and is used around the world in
criminal investigations!

Fingerprint analysis has been used to identify suspects and
solve crimes for more than 100 years, making it a valuable tool for law
enforcement. Each time we open a door, drink out of a glass, or type on a
keyboard, we are leaving our unique fingerprints! While identical twins share
the same D.N.A, but they have unique fingerprints! Each person’s fingerprints
are completely unique to them, and no one has the same fingerprints as you do!

Forensic scientists can find your unique fingerprint on
almost any solid surface you may touch, including the human body. Fingerprints
are formed when your body’s natural oils and sweat are deposited onto another
surface, but they can also be left when fingers coated in paint or ink touch
another surface. Fingerprints may be collected by taking a photograph, dusting
with a fingerprint powder, or even using special laser or LED lights to detect
the latent print!

Fingerprints have a general flow in which the ridges of the
fingerprint form, following into 3 pattern types: a whorl, loop, or arch. While
you may inherit the general pattern from your parents, as well as a similar
size, shape, and spacing of the ridges, your fingerprints are completely unique
to you!
