Our elf has opened a tiny detective lab. There are marks on the paper, tape at the ready and one small problem: he is wearing mittens. 🔍
He will need some human helpers if he wants to investigate actual fingerprints.
This easy elf idea sets up a simple pencil-and-tape activity for the morning, using ordinary stationery.
What you’ll need:
- One official Elf on the Shelf doll (paid link)
- A soft pencil and scrap paper
- Plain paper or card
- Clear sticky tape
- An optional Learning Resources magnifier (paid link)
- A folded cloth to support your elf
- A Tiny detective lab note
Setup:
Shade a small rectangle heavily with pencil on scrap paper. Leave it beside a clean sheet, tape and your supported elf, then add the note. You can make one demonstration print yourself before setting out the scene. In the morning, with an adult, rub a fingertip lightly over the shaded patch. Press a short piece of sticky tape gently onto that fingertip, lift it off and stick it onto the clean paper. Look for the curved lines in the grey mark, then try a second finger and compare the patterns. This pencil method is explained in NUSTEM’s fingerprint activity. No powder needs to be scattered around the room. Let the children wash their hands afterwards. The elf’s cloth mittens will not supply human fingerprints, which gives the little detective a funny reason to ask for help.
Make it cheaply:
Use paper from the recycling and the stationery you already own. A magnifying glass is optional; many prints are visible by eye in good light. If you do not want to take prints, draw two different swirl patterns and let the children spot how they differ. The detective scene works as a pattern game too.
Try the secret-code arrival or the disappearing coin trick for another elf scene.
