Preschool Science Activity: Melting Snowman

Melting Snowman

This melting snowman activity is a “Frosty the Snowman” approved preschool science activity that is sure to be a hit with your child. With some simple ingredients you probably already have in your kitchen, you’ll be able to do this science activity when your young child is stuck inside on a cold day. First, you’ll build your snowman with water and baking soda and then watch it “melt” away as the vinegar touches it. Here’s what you’ll need and how to do it, let’s have fun!


  • baking soda
  • water
  • vinegar
  • a bowl
  • a spoon
  • playdough/clay



  • Pour some baking soda into a bowl. Half a cup should be plenty for one snowman.
  • Slowly stir 1-2 tablespoons of water into the baking soda just until it’s wet enough that it clumps together if you pinch it.
  • Form the mixture into 3 snowballs each slightly smaller than the one before. Stack the snowballs with the largest on the bottom so they stand on their own to make a snowman.
  • Make clay details for the face and body and add them to your snowman.
  • Slowly pour or spoon the vinegar over the snowman and watch as it bubbles and melts away!
