Make a scale model of the Solar System and learn the REAL definition of "space."
The idea: Making scale models of the solar system is a useful way to learn about it. Here are various related pages.
This website is an overview of the history, mythology, and current scientific knowledge of the planets, moons and other objects in our solar system. Each page has my text and NASA's images, some have sounds and movies, most provide references to additional related information.
What is your address?
An address is basically a listing of where you live in terms of house, street, city, state, and country. We can identify each of these places on a map to find out where we live relative to other places. Knowing some geography, you can locate anyone in the world using their address.

Welcome to Celestia
... The free space simulation that lets you explore our universe in three dimensions. Celestia runs on Windows, Linux, and Mac OS X.
Unlike most planetarium software, Celestia doesn't confine you to the surface of the Earth. You can travel throughout the solar system, to any of over 100,000 stars, or even beyond the galaxy.
All movement in Celestia is seamless; the exponential zoom feature lets you explore space across a huge range of scales, from galaxy clusters down to spacecraft only a few meters across. A 'point-and-goto' interface makes it simple to navigate through the universe to the object you want to visit.
Celestia is expandable. Celestia comes with a large catalog of stars, galaxies, planets, moons, asteroids, comets, and spacecraft. If that's not enough, you can download dozens of easy to install add-ons with more objects.
