I got this idea from Flin Scientific. I made a bracket for the 32 of the moons in our solar system. The students are going to research and answer questions about different moons to determine who will make the playoffs, the semifinals and the championship game. Students should use the NASA website to help them answer questions about the moons such as the mass, year it was discovered, density, etc. I have attached a blank copy and answer key within this excel sheet.
