Here is an attention getting lesson that you can sketch as you go on the board or make a transparency and uncover as
you go. Discussion can cover topics such as: How do we know about these movements? Where have we been and where are
we going? Why don't we feel dizzy? End by saying that although planetary motions have been studied for years and
years, we still don't know where we've been or where we are going. Perhaps one of you will find those answers someday.
