Today students began to organize all of their research from Alien Invasion Week by making a solar system diagram. The premise of the project is that this diagram would be sent back home to their alien leaders and must describe the solar system in detail. Not only does the diagram need to show proper sizes, locations, and orbits of the eight planets, it also has a real-world element. Students will recommend locations for an alien city, a military outpost, an orbital mine, a solar telescope, and a global warming research lab. Only one of these is allowed per planet.
