The small amount of remaining material swirled into a disk. Some of it crashed together and formed planets. That's the main theory though most scientists think that's how it happened.
Scientists suspect there are many other solar systems like ours. And as of late, they had found nearly two dozen other planets orbiting faraway stars. None of them appear to have the right conditions to support life, though.
- Build a scale model of our solar system.
- Explain the forces at work when the planets orbit the sun. What keeps them in place? Are they moving further away?
- Study pictures from telescopes. Show the different planets in the pictures and their moons.
- What are the features of the planets? Could they support some kind of life? Why or why not?

About These Science Fair Projects:The science projects located here on the Parenting of Teens site at About.com are ideas developed by its Guide, Denise D. Witmer. Some are projects completed during her years of working with high school students, researched projects and others are original ideas. Please use these science fair ideas as a guide to help your teen complete a science project to the best of their ability. In your role as a facilitator, you should feel free to share this project with them, but not to do the project for them. Please do not copy these project ideas to your website or blog, post the link if you wish to share it.
