In a series of fun and involving hands-on astronomy experiments, kids learn how gravity affects the movement of celestial bodies, why and how a satellite stays in orbit, how the Earth is protected from solar winds, why the stars seem to move in circles in the night sky, and how to safely observe the image of the Sun. They will also determine and demonstrate why the Sun�s center is more dense than its outer edge, why charged particles are attracted near the Earth�s poles, and how planetariums produce images of the night sky. Featuring color illustrations and safe, simple step-by-step instructions, Janice VanCleave again shows just how much fun science can be.
