Make your own FingerPrints
To make our fingerprints, we first traced our hands on a piece of white paper. We then used an ink pad, and made fingerprints on corresponding with the finger outlines. Once dry, we began our investigation.
Fingerprints are Important
Fingerprints have been used by governments the world over for more than a hundred years and are still the most widely used form of identification.
Kids may already know about the identification use for fingerprints, but they will love to learn about the anatomical purpose of fingerprints. Without those one of a kind ridges, we wouldn't be able to grip things! Our fingerprints give our fingers the rough surface we need to create the friction that allows us to pick up a baseball or hold onto a pencil to take a test.
Kids will be interested to learn their fingerprints were on the tiny tips of their fingers long before they born, that they are 100% unique - no two people have exactly the same fingerprint. Explain how fingerprints are used to catch criminals and can also help to find lost children. Tell kids how fingerprints can leave an ‘invisible ink' of sorts that police can decode with special tools and equipment.
Fingerprints can last for years on an object if it is not cleaned after being touched. This can be observed easily on old silver. Pull out grandma's spoons or take a trip to the local flea market for a sample.
Types of fingerprints
Using a magnifying glass, discover your fingerprint type. Here are some examples of types of fingerprints.
Use the template (below) to create your own police badge. You can affix it to your shirt using rolled tape, or a safety pin. We colored ours with a yellow highlighter to obtain a bright yellow look, then added some gold glitter glue for a little sparkle. After the glitter glue had dried, we wrote in "Officer Allie" (our child's name).
Supplies Needed; Paper cup, black paint, red and black construction paper, glue, two wiggly eyes and a black pen
Cut out two ear shapes using the black construction paper, then cut out a tongue shape and draw a black line down the middle. Glue your ear shapes, tongue shape and wiggly eyes to your paper cup. Once they are dry, use your black paint to paint on spots for your Dalmatian.
This was a fun one to make. We painted our hands red, and then made thumb prints for heads. Once the paint was dry, we drew faces on our fire fighters, painted on little red hats, and used a black pen to draw on the hose. We opted to use glitter glue to make the water coming out of the fire hose, but blue ink will look just as good.
