Make a scale model of the Solar System and learn the REAL definition of "space." Enter how big you want to the sun to be in your model (in inches). Press calculate to see how to scale. Here is an example:If you build your solar system on a roll of toilet paper, you can make the Sun about .4 inches (10 mm) across and still fit the entire solar system on the roll. A standard roll of toilet paper has about 450 sheets that are about 4.375 inches long, hence the roll is about 164 feet long. You should check your toilet paper for length. Some are longer.

The pH Factor is designed as a resource to help elementary and middle school teachers introduce acids and bases to their students. Materials are organized using a conceptual framework called the Seven E's: Excite, Explore, Explain, Expand, Extend, Exchange, and Examine. This model can be used in a linear fashion or each E can stand alone. Each E contains an intercactive screen and lesson plans.
