Who doesn’t love a snow day? And while outdoors in the snow has its excitement, being stuck indoors can be awesome too.

A snow day often means wearing pj’s, eating snacks, and watching the snow flurries without getting cold and wet. And it means doing fun crafts like this snowman STEM.

This STEM activity invites kids to choose basic craft materials to make a snowman.

Because it’s STEM, kids will use math and engineering skills to design and build their snowmen, and create like artists as they add color and trims to their fun characters. 

They’ll sharpen their listening skills with simple directions to follow, practice hand-eye coordination, and complete the project with their own style.

Instructions for building a foam snowman

Snowman craft science challenge for kids

1. Stack foam balls on a straw or dowel. 

  • If you are stacking foam balls onto a straw, use a pencil to pilot hole in each foam ball.  This will allow the straw to be inserted easily through each foam ball.

2. Trim the excess straw. 

  • Leave a small piece exposed at the top. This is where the hat will be attached.

3. Support the snowman in a play dough base.

  • This will hold the snowman steady as you add the accessories.


4. Add accessories.

  • pipe cleaner arms
  • felt or fabric scarf
  • felt or craft eyes
  • felt nose and buttons
  • pipe cleaner arms

You can use small twigs for arms instead of chenille stems or pipe cleaners.

5. Make a hat.

  • Wrap a narrow piece of felt around the straw poking out at the top of the snowman.
  • Cut out a u-shape piece of felt. Glue to the snowman’s head for a hat brim.


6. Decorate with cotton ball snowballs.

Glue cotton balls around the base of the snowman for snow.

Learning through play

The process of adding parts one after the other requires some experimentation and creative thinking. Kids are thinking like young scientists as they build a snowman.

  • math skills to sort and count the foam balls
  • technology to make holes in the foam balls
  • engineering to design and stack the foam balls
  • science of materials and how they can be altered or used to complete a project

Don’t let blustery winter weather ruin your day. Enjoy the snow day indoors with this fun snowman craft.
