Modelling - Make a scaled model of the solar system

The following videos will show children how a class modelled the solar system:

The following website will allow you to work out the size of the models for the planets and the distances from the Sun based on the size of the Sun which you can choose:

The Earth orbiting the Sun
The following video animates the Earth year:

The children could draw a table, in which they record the diameter of the Sun and the eight planets, the scaled down diameters of these, and the scaled down distances from the Sun.
The children could make a model Sun that is 1 metre across, which they can then place on the school field/playground. They could then make, using plasticene, scaled models of the planets (be warned, Mercury is only 3.4 mm in diameter!). The children can then begin to place their model planets the scaled distances from the model Sun. This will prove particularly difficult when they reach Saturn, as this will be over 1 km from the model Sun!
