Before You Start: Gather all the ingredients to prepare the dough ahead of time. You will need: 1 cup baking soda, 1/2 cup cornstarch, 3/4 cup cold water and BioColor® paint in a variety of colors. Add baking soda, cornstarch and water to a saucepan and mix well. Cook over medium heat for 8-10 minutes, stirring often to prevent sticking. Cook until the mixture becomes soft clay. Remove from burner and cool. Once the clay is cool, divide into several balls. Make and indent into each one, and add a squirt of BioColor® inside. Close the clay balls so the color does not show.

Let's Get Started! Step 1. Place clay balls on a flat space for children to play with. Allow the children to knead the balls and make the colors appear. (The BioColor® paint is easy to wash off of the children's hands and will not make the soft clay sticky.)

Step 2. The teacher may talk about and introduce primary colors to the children as they are playing with the dough. Show children how they can then blend two of the primary colors and make secondary colors. The BioColor® paint will make a pretty, marbled effect on the soft clay.

Step 3. Let the children create their own unique shapes, designs, or whatever they wish – it's open-ended! Set their creations out to dry in the open air.

Step 4. Now everyone has their own clay creation to put on display and take home!

Furthermore: The teacher can designate a "color of the week" and provide each child with a clay ball in that color to use in related activities. Give each child a container to keep their clay moist.
