Make a model of the solar system--all you need is a thousand yards and some objects, most very small. All model planet sizes and locations are provided.
This ia a Great Exercise
Author: John Baitinger I made scale models instead of using the peppercorn, walnut, etc. The WOW factor is worth the time.

How Big is the Solar System?
(Editor: National Optical Astronomy Observatory)
Date: 10/19/2005
Date Description: How Big is the Solar System? If you have the fortitude to hunt up some materials, find a 1,000 yard patch of ground to work with (you can double back), and invest some time, you can make a model of the solar system that will give you a new perspective on its scale. In this model, the Sun is an 8" diameter ball and Mercury, the first planet, is but a pinhead located ten paces away. It gets better--Earth is a peppercorn 26 paces from the Sun, and, jumping out a bit, Jupiter, a chestnut, is 135 paces from the Sun. Among other things, walking along this model can give you a sense of the vast emptiness of space, interrupted occasionally by tiny model planets.
