Preschoolers love to be special. This preschool science activity will help preschoolers to understand that no two people are exactly the same. Preschoolers will learn that even their fingerprints are uniquely their own.

What You Need

White Paper
A non-toxic Ink Pad
Preschool sized magnifying glasses
Crayons

What To Do

Give each preschooler a white piece of paper. Write each preschoolers name at the top of the paper, or help each preschooler to write their own name.  Ask if anyone knows what the word “unique” means. Tell them that unique means that there is only one of something. Have every preschooler hold up their hands and tell them that their hands are unique. Tell the preschoolers that there are no two people in the world who have the exact same fingerprint.

Give each preschooler a magnifying glass and have them look at their fingertips closely. Ask the preschoolers to describe what they see on their fingertips. Have the preschoolers draw what they see on their fingertips in the center of their white paper.

Help each preschooler to use the ink pad to make fingerprints on their paper. Encourage them to make fingerprints of all of their fingers.

Line up all of the fingerprinted papers on a table. Have the preschoolers take their magnifying glasses to the table and look at everyone’s fingerprints. Ask preschoolers to look closely at the differences that everyone has in their fingerprints.
