Overview
The child discovers that secondary colors are created by mixing two primary colors together. Using droppers and small containers of liquid watercolor or tempera, the child experiments with combining red, yellow, and blue to produce orange, green, and purple.
Objectives
What the child gains from this work
Identify the three primary colors: red, yellow, blue. Discover through experimentation that mixing two primaries creates a secondary color. Name the three secondary colors: orange, green, purple. Develop fine motor control through dropper use. Experience cause and effect in a creative context.
Materials Needed
Gather these before presenting
- Three small jars of liquid watercolor or diluted tempera (red, yellow, blue)
- Six clear cups or a white ice cube tray for mixing
- Plastic droppers or pipettes (one per color)
- White paper or cardstock for painting results
- Smock or apron
- Paper towels for cleanup
Presentation
Follow this sequence during your presentation
- Invite the child; put on smock and prepare the workspace with protective covering.
- Present the three jars: "These are our primary colors — red, yellow, and blue. They cannot be made by mixing other colors."
- Place three empty clear cups in a row; explain: "Let's discover what happens when we mix two colors together."
- Demonstrate using the dropper: squeeze the bulb, dip into red paint, release to draw up liquid, then squeeze 3-4 drops into the first empty cup.
- Using the yellow dropper, add 3-4 drops of yellow to the same cup; invite the child to observe: "What color do you see?" (orange)
- Name the result: "Red and yellow mixed together make orange."
- Invite the child to try the next combination: yellow and blue in the second cup (makes green).
- Guide the child to try the third combination: red and blue in the third cup (makes purple).
- Line up all three mixing cups beside the original primaries; observe the color relationships.
- Offer white paper and a brush for the child to paint using both primary and newly mixed secondary colors freely.
- Guide cleanup: rinse cups, replace droppers, wipe surface, hang painting to dry.

Extensions
Where to go when the child is ready for more
Explore what happens when all three primaries are mixed (brown/dark). Introduce tints by adding white, and shades by adding black. Create a color wheel painting showing primary and secondary color relationships. Experiment with mixing different proportions (more red + little yellow = red-orange).

Points of Interest
Use food coloring and water instead of paint for a simpler setup. For outdoor version, use colored ice cubes melting together on a tray in sunlight.
