For my kids' elementary school classes I once made a billioin-to-one scale model of the solar system and had the kids help lay it out on the play fields around the school

The Sun was a cardboard ring about 55" in diameter.
Earth was a 1/2" marble, and the moon was a little squashed ball of tinfoil maybe 15" away.
Earth to Sun distance = 491 feet!
Earth to Mars distance = 686 feet!

We didn't have room for Jupiter - nearly half a mile, and Uranus 1.8 miles away!! But they did get a sense of how much empty space there is in the Solar system.
