Here is a scale they might be able to draw them first. I'm not sure what kinds objects might match these sizes. Maybe marbles, ping-pong balls, tennis ball, basketball, beachball for some of them? Name Diameter Radius Mercury 1 1/2 Venus 3 1 1/2 Earth 3 1 1/2 Mars 1 1/2 3/4 Jupiter 33 1/2 16 3/4 Saturn 28 1/2 14 1/4 Uranus 12 6 Neptune 11 1/2 5 3/4 Pluto 1/2 1/4 I haven't done this before. I have used different colors of playdough for a model of Earth's layers. Start with one color ball for the inside core. Keep wrapping a different color over it for the different layers. The outer layer was blue and green. At the end, they cut the Earth in two and it shows the layers. I had posters to match. Good luck on your observation! Mine is next Wednesday (Reading).
