Make the Sun a football at one end of your street and walk to where each planet would go. Two sheets that tape into one Sun, and every distance in your own steps as well as in metres.
Make the Sun a football at one end of your street, then walk to where each planet would go. Sheet 1 is the Sun and the four near planets — specks a few dozen paces apart, each printed at its true size and magnified beside it. Print it on sticker paper if you have some.
Sheet 2: Jupiter, Saturn, Uranus and Neptune, drawn at the same scale as the Sun on sheet 1 — and most of a kilometre of walking. Tape the two Suns together and the whole model is one object.
