This is a 20-piece miniature solar system model with a light-up sun. The separate Earth-and-Moon model demonstrates day and night, the phases of the moon, Earth's seasons, and solar and lunar eclipses. Ten interactive activities include mapping out a scale model of the solar system, making impact meteors, demonstrating eclipses, and creating art using the Sun's UV rays. A colorful mega-mini poster brings the solar system to your bedroom wall!
