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!
Step 1:
A) 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:
A) Roll the clay strips into 5 balls. The clay balls should gradually go up in size.
Step 3:
A) Collect 5 different acrylic paint colors for the Earth’s layers. We used: red, orange, yellow, purple, and blue.
B) Wearing gloves, add paint to the balls. Tip: Press your thumb into the center of the ball to make a placeholder for the paint.
C) As in kneading dough, thoroughly work the paint into the balls.
Step 4:
A) Have the smallest pile of clay rolled into a ball.
B) 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.
C) Roll this back into a ball shape.
D) Repeat steps B) and C) until all layers are completed.
Step 5:
A) Have an adult help cut Earth clay ball in half.
B) 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:
A) Bake clay Earth at 250° F for approximately 15 minutes. Periodically check the Earth to watch for any cracking in the clay.
B) Remove from oven and let cool.
Extra step:
A) Label the Earth’s layers with fun flags! Cut toothpicks in half for the poles.
B) Cut approximately 1/2" x 2" rectangles from white paper.
C) Fold a paper rectangle in half around the top of each toothpick. Adhere with glue or tape runner.
D) Label flags with a pen.
