Students will label the diagrams of the Geocentric and Heliocentric Models. They will then use the information from their diagrams in addition to their notes, textbook, or internet to answer questions about the contributions of Ptolemy, Copernicus, and Kepler. I have used this activity as a classwork assignment (station activity), a homework assignment, as well as a formative assessment. You can also view a full preview of this assignment :) ******************************************************
