For our younger scientists, celebrating the seasons means picking out special themes that kids love! Snowmen in winter are always popular, and our melting snowman activity is always a hit. Make a snowman and then watch what happens with a cool chemical reaction for fun winter science activities for preschoolers you can do with a classroom group or at home!
MELTING BAKING SODA SNOWMAN
FUN SNOWMAN SCIENCE
The best part of this snowy winter science experiment is that you don’t need real snow to enjoy it! That means everyone can try it. Plus, you have everything you need in the kitchen to get started.
This baking soda experiment has to be prepped ahead of time, but it’s not difficult! You can make your baking soda snowman in any shape you want. We have even used small paper cups, which you will see below.
While the baking soda snowmen are not really melting, you can see a fun chemical reaction at work that will be use up all the baking soda and change it into fizzing bubbles.

MELTING SNOWMAN ACTIVITY
You will want to make these snowmen or snow-women in the morning for afternoon play or in the evening for morning play as they need to time to freeze! The kids can quickly help mold their own snowmen.
- Baking Soda
- White Vinegar
- Black Beads or Google Eyes
- Orange Foam Paper
- Basters, Eyedroppers, or Spoons, teaspoons
- Glitter and Sequins
HOW TO MAKE BAKING SODA SNOWMEN!
STEP 1. Start by slowly adding water to a good amount of baking soda. You want to add just enough until you get a crumbly but pack-able dough. It shouldn’t be runny or soupy or like our snowflake obleck.
STEP 2. Pack the mixture together to make them into snowballs! You can use plastic cling wrap to help keep the shape if needed.
STEP 3. Gently press two beads or google eyes and an orange triangle nose into the snowball for the snowman’s face. You can also mix in buttons and sequins!
STEP 4. Place in the freezer for as long as you like. The more frozen the balls, the longer it will take to melt them!
While you’re waiting for the snowmen to freeze, go ahead and try one of these melting snowman activities.
Alternatively, you can make these melting snowmen inside small plastic or paper cups, as seen below. You can add a face to the bottom of the cup and then pack the mixture on top of it. It’s a quick and easy way to make a whole team of snowmen!
SNOWMAN CHEMICAL REACTION
It’s time for the fizzing fun with your baking soda snowmen!
STEP 1. Set out your snowman activity with a baster, eyedropper, squirt bottle or spoon, and a bowl of vinegar. You will want to make sure to put your snowmen on a tray or dish that will hold the liquid.
Add a drop of blue food coloring to the vinegar for an icy blue winter look! It made the dish as pretty as the snowmen fizz. Of course, you can add even more glitter for a festive look!
STEP 2. Add vinegar to the baking soda snowmen, and watch what happens!
WHAT HAPPENED TO THE SNOWMEN?
It may look like the baking soda snowmen are melting away when you add the vinegar. However, melting involves a physical change from a solid to a liquid, like our melting crayons.
Instead of melting, a chemical reaction occurs between the baking soda and the vinegar, producing a new substance called carbon dioxide gas. This happens when a base (baking soda) and an acid (vinegar) mix. That’s all the bubbling and fizzing you can hear, see, smell, and touch!

This snowman activity makes for a great preschool science experiment. It’s the perfect theme for wintertime and will get the kids excited to learn more this year!
In the end, we enjoyed winter sensory play with the activity that was left. We talked about the cold vinegar water and the fizziness from the gas that was created. We stirred it for more fizzing action and used our hands to pick up the melting snowmen.
You can also set up snowflake cookie cutters for winter baking soda and vinegar science experiments.
