This activity uses the website (http://earthobservatory.nasa.gov/Features/OrbitsHistory/) to have students answer questions on the history of planetary motion. This website includes information on Aristotle, Copernicus, Kepler, Newton, and Einstein, and how each of them contributed to our knowledge of planetary orbit.
I designed this lesson for my 9th grade, general earth and space science students. This is a great lesson to teach students about the history of science and about how scientists really work!
