This Planetarium is a model of our Solar System. Watch the planets move around the Sun, powered by the Sun itself or the back up battery when there is no sunlight. The green conversation is going on everywhere. Clean energy and water solutions are increasingly major priorities for governments and research institutions. Green technology is the industry of the future and kids are excited to be a part of it today. They feel proud to be green, proud to solve eco-problems and proud to do it themselves. Green Science teaches the principles of renewable solar, hydro, magnetic, gravity, and wind power and teaches kids to build cool, clean machines that really work!
