Fingerprints. They’re everywhere! We’re used to cleaning them off every surface our kids touch, over and over and over again. But fingerprints can be fun!

Fingerprints

Every fingerprint is different, and since we leave our fingerprints on everything we touch (We know, right?), we can use fingerprints to identify people. Forensic scientists “lift fingerprints” from crime scenes to help them determine who was there. We found this great fingerprint lifting activity in The Usborne Big Book of Science Things to Make and Do
. You and your super sleuths can do it, too.

Here’s what you’ll need.

Fingerprints Supplies

Supplies:

  • Chalk
  • Scissors
  • A bowl, lid or container
  • OR

  • Cocoa powder
  • AND

  • Clear tape
  • A dry brush

Directions:

  1. Use a pair of scissors to scrape a piece of chalk over a container to collect the powder or just grab some cocoa powder.
  2. Fingerprints 1

  3. Find or make a fingerprint. We had plenty to choose from: fingerprints on the door, the windows, the television screen. We decided to use fingerprints from a glass vase.
  4. Dip the brush into the powder and carefully dust it onto the fingerprint. The dust will stick to the grease from your finger.

  6. Blow off any excess powder and lay a piece of clear tape on the fingerprint. Press the tape flat, then carefully peel it off. Congratulations, Detective! You’ve lifted the fingerprint!
