This ice cube activity is perfect for cooling down on a hot day, while also helping children learn about how colors interact with each other.
This activity requires very little set-up. All you’ll need is water, tempera paint (in yellow, red, and blue), plastic containers, and easy-to-make colorful ice cubes. If you are working with younger children who might be interested in tasting the ice cubes, or if you don’t have tempera paint on-hand, you can also set up this activity with food coloring, but note that the colors might not be as vibrant.
Mix a few squirts of paint (or a few drops of food coloring) with about ¾ cup of water and pour into ice cube trays. Let them sit for a few hours, or overnight. Once the ice is frozen, set up different containers with two different colors in each and encourage children to guess what the water will look like when the ice melts. Young children will get to observe the colors changing, and some might even enjoy putting their hands in the icy water to add a fun, sensory experience!
