Wonderopolis Jan 5, MacyJohnson Jan 5, Every day in my home room, we have to write three facts. Here are mine, did you know that know no one in the whole world has the same fingerprint as you or me, not even identical twins have the same fingerprint. Last year my teacher Mrs. Martin had us dip are finger into ink so we could find out what are fingerprint is. I have different kinds of fingerprints.

I thought it was pretty cool. You should try it out sometime. Well, thanks wonderopolis for being here for our questions to answer Sincerely, Macy. Paige Jan 4, Dear Wonderopolis, Everyone's fingerprints are different. That is one of the things that make them unique. I think there are 3 main types of fingerprints, an arch, loop, and a swirl.

I also think it's cool that we can be identified by our fingerprints. Thank you for being awesome wonderopolis! Wonderopolis Jan 4, Rebecca Jan 4, I think tomorrow's wonder will be something about waking up? Maybe I'll just have to wait and see!!

The Beach Mrs. Guerin's 2nd G Jan 4, Thank you for the interesting Wonder! We made thumbprint art and then looked at our fingerprints under a magnifying glass. We looked up more fingerprint patterns. We discovered that most of our class has the loop pattern and only a couple of students have the pocket pattern. We wonder if the loop pattern is more common. I think it will be faster if you put your finger in a finger scanner, so it won't take long.

I wish we had that at our school. I think it was cool. I made a fingerprint myself. We used pencil lead rubbed on our fingertips and put them on paper. North Todd Elementary School We think that it is interesting how everything we touch we leave a fingerprint. We liked the video and thought it was cool how the students only pushed their fingertip on the machine to leave a print or for the print to be scanned. Thanks a lot Wonderopolis! We had a lot of fun with today's fingerprints!!

Good stuff. I thought identical twins had the same fingerprints. Shoemaker's Class Jan 4, We think this is a great idea! We spend a lot of our lunch time putting our numbers into the machine. We think our school should try this out too! This way we won't have to memorize our numbers! Our question: Do all fingers on the same hand have the same fingerprint? Dominque at kerrick Jan 4, Hey wonderopolis. This wonder was really cool. My fingers have a lot of lines. I noticed when I touch a window, my finger prints stay on the window.

Megan Jan 4, We have to write three facts each day. He are my three facts: no one else in the world has the exact same set of ridges and lines that you have on your fingers. You don't have to dip your finger in ink to leave a fingerprint. Those are my three facts. My fingerprint is a loop! I think tomorrow's is about sleeping or resting :D.

For example, the shape and size of the blood vessels in your skin, how fast the different layers of skin are growing, and the chemical environment inside the womb all play a part.

No two people end up with exactly the same fingerprints, even identical twins. Even if you have a major skin injury, your prints will come back when the outer layer heals — though you might have a scar, too. So your fingerprints are totally unique to you and have been since before you were born. People have long thought that fingerprints provide the friction that helps our hands grip objects. This makes sense because the other animals besides human beings that have fingerprints — including many other primates like apes and monkeys, and koalas — are all tree climbers.

Other possibilities are that fingerprints improve your sense of touch or help protect your fingers from injury. Police have been using fingerprints and their unique loop, whorl and arch shapes to help catch criminals for more than 2, years, starting in ancient China.

If one layer of cells grows faster, it can stretch and pull the others. As the fetus moves, their fingers can rub against the side of the womb. These tiny forces push the skin as it grows. Together, they mold the direction of the growing ridges. Koalas and chimpanzees have unique fingerprints, too.
