Color Mixing and Melting Activity!

This project requires very few materials

Experiment with color mixing. Create as many different colors as you can. Examine how salt can affect ice.

Here’s what you need:

  • ✔ Food Coloring
  • ✔ Ice cube tray
  • ✔ Water
  • ✔ Salt
  • ✔ Bowls
  • ✔ Freezer


  1. Fill ice cube tray with water.
  2. Add drops of food coloring to individual sections, making some cubes blue, some red, and some yellow.
  3. Wait for ice to set
  4. After the ice has set, take the ice cubes out of the tray and place them into bowls. Combine red and blue, yellow and blue, red and yellow, etc.
  5. Wait for the ice cubes to melt and observe how the colors mix!

Thought provoking questions for your scientist:

What colors did we mix to make purple? Green? Orange?

How did the salt change the melting process?

Can you try and make brown?
