Level of difficulty:  Beginner

Get your science on! Show off your knowledge of the different layers of the Earth with this clay craft. Great for science fairs or classroom lessons!

What You'll Need:

  • Crafter’s Closet Oven Bake Clay
  • Crafter’s Closet Acrylic Paint
  • Disposable Gloves (optional)
  • Toothpicks
  • Sheet of White Paper
  • Crafter’s Closet Tape Runner
  • Crafter’s Closet Precision Scissors
  • Pen

Let's Do This!


Step 1:

  1. Place rectangle block of clay horizontally on a cutting surface. Measure and cut strips from the clay block. Measuring across the top of the rectangle: 1", 1 1/4", 1 3/4", and 3". Cut a 1" x 1" cube from the end of the 1" strip.


Step 2:

  1. Roll the clay strips into 5 balls. The clay balls should gradually go up in size.


Step 3:

  1. Collect 5 different acrylic paint colors for the Earth’s layers. We used: red, orange, yellow, purple, and blue.
  2. Wearing gloves, add paint to the balls. Tip: Press your thumb into the center of the ball to make a placeholder for the paint.
  3. As in kneading dough, thoroughly work the paint into the balls.


Step 4:

  1. Have the smallest pile of clay rolled into a ball.
  2. Flatten out the next biggest color ball and wrap it around the smallest ball. Tip: Place the smaller ball in the center of the flattened ball.
  3. Roll this back into a ball shape.
  4. Repeat steps B) and C) until all layers are completed.


Step 5:

  1. Have an adult help cut Earth clay ball in half.
  2. Smooth out any spots on the layers with your fingers. Tip: Add texture to the layers by using a toothpick or pencil for a more realistic look.


Step 6:

  1. Bake clay Earth at 250° F for approximately 15 minutes. Periodically check the Earth to watch for any cracking in the clay.
  2. Remove from oven and let cool.


Extra Step:

  1. Label the Earth’s layers with fun flags! Cut toothpicks in half for the poles.
  2. Cut approximately 1/2" x 2" rectangles from white paper.
  3. Fold a paper rectangle in half around the top of each toothpick. Adhere with glue or tape runner.
  4. Label flags with a pen.
