Preschool Biology Activity – Make Fingerprints into a Mothers Day Card

Does your preschooler know they have fingerprints? Do they know their fingerprints are individual to them—no one else has fingerprints like them? Are you looking for a fun activity that combines science and a mother’s day present?

What your Preschooler will Learn from this Preschool Biology Activity:

That they have fingerprints
That fingerprints are individual to them
What fingerprints look like

What you Need for this Preschool Biology Activity:

A magnifying glass
Paper
Ink Pad
Crayons
Markers

What To Do:

Step one: Have your preschooler inspect their fingertips with the magnifying glass. Point out the fingerprints. Point that that the swirls may be circles, loops or other shapes.

Step two: Have your preschooler inspect your fingerprints. Ask them if your fingerprints are different than theirs. If they’re old enough, have them draw the fingerprint shapes in their scientific journal.

Step three: Trace around your preschooler’s hand using your crayons or markers onto the paper.

Step four: Press their fingertips into the ink pad, and press their finger tips onto the hand that you drew. Match up the fingers. For example, make sure the thumb of your hand has the thumb print on it. You may need to do the fingers one at a time.

Step five: Have your preschooler decorate the mother’s day card.

Step six: Give your mother’s day card to a mother or grandmother.

Why Decorate a Mother’s Day Card with your Preschooler’s Fingerprints?

Fingerprints are caused by the movement of the amniotic fluid that surrounds babies before they’re born. This is why identical twins don’t have identical fingerprints. As your baby develops inside of you, your movements, how you moved during your pregnancy helped determine what your child’s fingerprints look like. Since fingerprints don’t change, but a child’s hand size will, getting a special mother’s day card decorated with your preschooler’s fingerprints is a wonderful gift and memory you can always cherish.
