Fingerprints

Fingerprints

Fingerprint Evidence We leave fingerprints on everything we touch hundreds of times a day. We leave them on drinking glasses, silverware, 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.

Now, learn how to take a fingerprint from an object – this is called picking up latent fingerprints. These are the fingerfetchhat_regprints that have been left behind. One way detectives find fingerprints is by dusting the crime scene for them. Fingerprints are coated with powder, then lifted and taken to a lab for identification.

Here are three website that can help you learn all about dusting for fingerprints.

Sandy’s Circus

Sandy’s Circus

Sandy's Circus

Read about Alexander Calder in Sandy’s Circus – As a boy, Sandy was always fiddling with odds and ends, making objects for friends. When he got older he started creating wire sculptures. Sandy made a lion. Next came a lion cage. Before he knew it, he had an entire circus and was traveling between Paris and New York performing a brand-new kind of art for amazed audiences.

Alexander Calder (nicknamed “Sandy”) was an American artist in the early 1900s. He is best known for making mobiles. He is also famous for making a miniature circus out of wire and bits of metal and string. This book is the story of Mr. Calder and his circus. The circus figures were tiny mechanical toys that used springs and string and air to move. Mr. Calder carried the little circus around in suitcases and would unload all of the pieces and perform the circus himself – kind of like a puppet show. You can watch the video below and see the real Mr. Calder performing his circus show. Remember that each of those circus figures he made out of bits of trash. Now that’s an artist – making a work of art out of trash! In the video, the circus pieces balance and move and do exactly what he wants them to do – and they look like what they are supposed to look like too…the lion, the trapeze artist, the elephant. Watch the horse rider figure flip in the air and land balanced on the horse – how did he do that? Amazing!
