The sun, an average star, is the central and largest body in the solar system. Most objects in the solar system are in regular and predictable motion. Those motions explain such phenomena as the day, the year, phases of the Moon, and eclipses. Short Description: "Solar System Math" is a series of four classroom lessons centered on pre-algebra topics such as measurement, unit conversion, ratio and proportion, scale, data analysis, and data representation. The downloadable software application, "What's the Difference," supports the lessons with engaging multimedia that accurately illustrates the size, distance and composition of the bodies in our solar system.
