extend the play: color science

Color Science Experiments for Preschoolers

Preschoolers love color! (Who doesn’t really?) Know what compliments playing our online preschool games like Colorific, Color Wheel and Dino Parade? Kitchen color science experiment fun – perfect for preschoolers! The activities below introduce basic science concepts including various steps within the scientific method. Plus water play. It’s a win-win for preschooler and parent.

What You’ll Need

Test Tubes with Lids (or any long skinny clear container with a lid)
Food Coloring (gels work great!)
Eye Dropper
Plastic egg carton, painting palette or any container with small wells
Paper Towels

Experiment #1: Dyeing the Water

Chances are your KneeBouncer may or may not be familiar with food coloring. Show him or her the test tubes and fill each one 3/4 of the way full with clear water (you may even want to let your child do this). Then have your child add a few drops of food coloring into each tube and make an observation: What happens to the water? Cap the test tube and let them shake away to mix! We made the three primary colors: red, blue and yellow.

Experiment #2: Mixing Colors

Don’t worry — the kids won’t get messy with this one! Have your child take two test tubes and cross them, while holding them up to a window. What color is made when the two tubes cross? Have them repeat this with another pair of colors.

Experiment #3: Mixing Colors with an Eye Dropper

Now it’s time to get some water play in! Have your preschooler use an eye dropper to mix colors in the plastic egg carton or palette. Before they mix, ask them to activate their prior knowledge about what happened in experiment #2 and make predictions: What happened when we crossed blue with yellow? Do you think the same thing will happen when we mix the yellow and blue water together?

Isn’t it great when the kids can play and learn? Enjoy!
