From the introduction:
Be Your Own Solar System is an immersive and collaborative game-based learning program from Seekers Unlimited in which students and teachers assume the roles of celestial bodies in outer space in order to gain a deeper understanding of the physics norms that govern our known universe. In order to construct a stable solar system, students will research and explore the composition of the basic elements of a solar system (e.g. stars, asteroids, planets, etc.), how each are quantified and analyzed in terms of mass, volume, and density, and how each are affected by one another by physical forces and the phenomena of gravity, all in order to fulfill in-game objectives. This program is designed to be implemented over the course of five one-hour class periods, complete with ample guidance in how to either shorten or extend each activity as desired.
