Children will replicate the inner solar system in their playground based on a scale of 1 391 900 000:1 or 1.391 x 109:1. The model of the sun will have a diameter of approximately 1m. The scaled model of the sun, the earth and the other inner planets will be made in three dimensions and will be placed in their correct orbits to the same scale. If extended to include the outer planets, the children will also need to use some public facilities in the school neighbourhood (such as a coffee-shop or a garden).
