Clay Solar System

Today we are making a model that is out of this world! Educational posters and models are a good way to keep learning materials around the house – especially in your child’s bedroom. This project is a perfect self-made, informative art piece for your kid’s wall.


The solar system is made of the sun and the planets. The sun is actually a big star. The planets in order from the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Pluto is sometimes not classified as a planet, so you can opt out of including it if you want. Click on this link for more on each planet. A great way to remember the order of the planets is to learn this little saying: “My very educated mother just served us nine pizzas.”


  • Step 1: Paint the poster board black for the sky. Use the glitter paint to make it shiny and bold.

  • Step 2: Mold the planets and make sure you are sizing them correctly relative to one another.

    • A sample range when considering sizes for planets, from large to small, might measure:

      • Mercury (orange): 1 inch

      • Venus (yellow): 2 inches

      • Earth (blue): 2 inches

      • Mars (red): 1 and 1/2 inches

      • Jupiter (brownish with a red spot): 4-7 inches

      • Saturn (yellow with red ring): 3- 6 inches

      • Uranus (green): 4-5 inches

      • Neptune (blue): 3-4 inches

      • If you want to include Pluto (gray): ½ inch

  • Step 3: Paint the planets. Make sure to paint them in colors that are close to what they look like (ie: paint the Earth with blue and green)

  • Step 4: Let everything dry

  • Step 5: Glue the planets to the poster board in order of distance from the sun.
