Abstract
This activity was originally developed by a group of teachers in Japan during 1960s under the influence of the American Curriculum-Reform Movement. This was used in Earth Sciences in order to develop the students’ cognitive skill. Kepler had been trying to analyze Tycho's observations of Mars, fitting them into the Copernican orbital system. It simply would not work. The problem is with the circular orbit that the Copernican system still used. Mars obviously did not have a circular orbit about the Sun. So Kepler tried a variety of other geometrical shapes, until he finally found the ellipse.
