Earth’s Core Model

This project is a great way to provide a visual demonstration of the different layers inside the earth. Children can improve their modelling and
co-ordination skills by creating the multi-layered ball of clay, and once it’s dry it can be cut into two pieces to reveal the effect inside

How to Make

  1. Roll out a small ball of red air dry clay, warming it in your hands until it’s smooth and malleable. This will represent the earth’s core.
  2. Cover the ball in a layer of orange clay, smoothing it around the ball of red until it’s completely coloured and devoid of cracks. This will represent the outer core.
  3. Then add a layer of yellow clay for the mantle. Your ball should be growing in size.
  4. Add a thin layer of black clay, ensuring it’s all completely covered. This will be the earth’s crust.
  5. Finally, add a covering of blue around the ball for the sea, then add patches of green for land. Leave to dry.
  6. Once dry, cut the model in half using a sharp knife to reveal the layers inside.

Top Tip

The clay bonds together quite quickly so roll out each layer before wrapping it around the clay ball to ensure you have enough to cover it – otherwise as soon as you put them together they will bond, making it difficult to separate the colours if you need to.
