Science isn't Usually Done by a Vote

In this game, students play one of nine astronomers arguing the definition of a planet at a 1999 debate in New York City and a 2006 meeting of the International Astronomical Union. During this game, students will compare the history of Pluto’s discovery to that of the asteroid Ceres, describe the properties of the Kuiper Belt and its members, Plot the orbital and physical properties of planets, asteroids, and comets, and ultimately debate the necessity and value of scientific classifications.
