Skill Development:  Color
Minimum Age:  Preschool
Messiness:  Medium



  • Marshmallows - 9 large
  • Coconut Oil - 2 Tablespoons
  • Corn Starch - 1/4 Cup
  • Food Coloring - Red, Yellow, Blue
  • Microwavable-safe Bowl
Books to Read

*Reading enhancing the learning environment

Step 1: 

Combine marshmallows, cornstarch, and oil into a microwavable bowl. Heat for 20 seconds, then stir.  Repeat until all has melted and mixed together.

Step 2:

Separate the melted marshmallow mixture into three bowls.  Adding drops of food coloring to each bowl. Red. Yellow. Blue.


These are Primary Colors, as they cannot be created using any combination of other colors.

Step 3:

Place the three Primary Colored pieces in front of the children and discuss colors of the rainbow (ROYGBIV)

Red Orange Yellow Green Blue Indigo Violet.

Primary Colors:  Red, Yellow, Blue.  All other colors are made up of these three.

Step 4:

Ask the children to separate each color into three little balls.  This is great for fine motor skills, listening skills; you can even incorporate counting into this step.

Step 5:

Allow the children to begin mixing two color combinations.  You can start by asking them what they think will happen when they mix Yellow with Red. Red with Blue? Blue with Yellow?

Encourage them to squish, twist, mush, roll… This is a great sensory activity and watch their excitement as the new colors start to appear.  These are called Secondary Colors.

How 2 Play:  Now for the Fun!

Step 6:

They’ve just created a Color Wheel showing the Primary colors (Red, Yellow, Blue) and then they created Secondary colors (Orange, Green, Purple).

Great opportunity to teach colors of the Rainbow in order.

And now, the best part, they can eat their colorful creation!
