Snowman Weather Gauge STEM Activity

A snowman weather gauge is fun for kids to make to measure snowfall. Set your snowman outside on a wintry day to observe how much snow falls around him.

Winter brings snow to many places around the world. Sometimes this means more time spend indoors if the weather is especially cold or blustery.

Make the best of snow days in your area with a fun snowman weather gauge that can measure the amount of snowfall. Kids can make predictions and observe results with this fun STEM activity.

Snowman weather gauge

A gauge to measure snowfall provides a fun STEM activity for young scientists. Designing and building the snowman promote engineering skills and support cognitive development.

Build the snowman with foam plates and basic craft supplies. Place the snowman in a secure area outside.

Kids can observe the amount of snowfall as it piles up around the snowman.

  • Foam plates: Use two large for the body, one small for the head or cut a large plate smaller. You can also use round plastic container lids or cut circles from foam trays.
  • Foam tray: Draw a hat on a black tray with chalk. Cut out the hat. Cut round buttons from the leftover part of the tray. (Use trays from packaged baked goods, not from meat products, for safe handling even though the trays will be washed.)
  • Craft foam sheets: Cut out a scarf and a carrot nose for the snowman. 


Snowman craft using recycled foam trays


1. Build the snowman by attaching the foam plates to a long strip of plastic or wood with a glue gun. We glued our snowman to a wooden slat from a window blind.

2. Measure upward from the bottom of the first foam plate in inches or centimeters. Mark increments with a permanent marker.


Snowman STEM activity for kids


Secure your snowman to a railing, post or even a tree trunk with rope or string. The bottom foam plate rests on the ground or on a surface such as a deck or table.

In our case, the bottom of the first foam plate rests on top of a coffee can on a deck. 

We measured the snow using the top of the coffee can as our starting point. 


Winter science for kids with a snowman weather gauge


Our snowman was placed outside just before a snowstorm. We had a lot of snow that day!

The top plate actually blew off in the wind but we were able to replace it before the snow ended. 

This is a fun and easy science activity. Kids will love watching the snow get deeper and deeper as it swirls and piles up around the foam plate snowman.

And unless you can read the numbers from a window or doorway, someone will have to bundle up and go outside to check the height of the snow! 

Learning through play

1. Measure the different parts of the snowman as it is being made.

2. Measure the height of the completed snowman.

3. Make predictions on how much snow will fall.

4. Bring some snow inside on large plastic trays to make snowballs. Build snowmen using snowballs of different sizes.

Winter Science Activities at Embark on the Journey


To build the snowman, kids will incorporate S.T.E.A.M principles.

Science: Discuss the changes in weather.

Engineering: Design and build the snowman and its support.

Art: Choose colors for the hat and scarf.

Math: Measure the snowfall.


Hands-on interaction with materials promotes critical thinking, applying STEAM principles as kids play!
