"The Schoolyard Solar System was developed to demonstrate the solar system to scale; to show the relationship between units of thousands, millions, and billions; and to accomplish these goals with student involvement that will re-enforce the lessons." Students and educators can find images of the Sun and the nine planets in our solar system. The website presents bulk, orbital, and observational parameters as well as additional facts for the objects. By printing out the materials and following the hands-on activity discussed at the website, students can learn about the scale of the solar system.
