Melt Ice For LEGO Sensory Play And Science

Creating an ice melt activity is quite easy, but takes a few hours, so plan accordingly! You can check out our best tips for the making the perfect ice melt every time!

Melting ice is also fun science for toddlers to preschoolers. Why is this? It is a simple way to introduce states of matter. You have frozen water which is a solid called ice. When the ice melts, it becomes a liquid.

Older kids will love our ice melting experiment with salt!

Encourage kids to make observations with their 5 senses throughout the activity.

  • What does it look like?
  • What does it smell like?
  • How does it feel?
  • What sounds does it make?

Ice melting is a pretty easy concept for kids to understand and it is so easy to create icy themes that include your kid’s interests, like this LEGO themed ice melt!

Tips For Making A Great Ice Melt

Below we show you how to set up your LEGO ice melt in an ice cube tray. Alternatively, you can create one large ice block by using something like a milk carton. I like using the milk carton because once frozen, you can easily rip away the container.

The most important part of creating a great ice melt is to freeze your characters in layers. I do 4 to 5 layers in the milk carton with a few figures in each layer.

You can chose to color the water by adding a few drops of food coloring and also you can add glitter.

Once completely frozen, tear away this container and place in a shallow pan/dish. This will help collect the water once it melts.
