This game is designed to focus on Virginia Standard of Learning SCI.6A.4.1.11 (compare and contrast the ideas of Ptolemy, Aristotle, Copernicus, Kepler, and Galileo related to the solar system), but is aligned with several other state standards. The focus is on 7 different early astronomers (Ptolemy, Copernicus, Aristotle, Galileo, Kepler, Hubble, and Newton). The game package includes printable materials to assemble 7 different “Early Astronomer Trading Cards”. Also included is a booklet to be assembled that students will use the trading cards so they may answer questions about each astronomer using the card backs. There is a 2 question short answer section that can be used to close the activity. One is an opinion based question and the other asks about Heliocentric and Geocentric universes.
