Check the Quick Reference Chart for topics that could be used for Focus Question 2.  Although particular topics may appear in only one or two eras, many of the topics may actually apply across several or even all of the eras. Please also remember that the chart does not pretend to be complete.  It contains examples of topics to suggest areas of inquiry and questions to explore, and no one is expected to cover all the topics.

Other examples may occur to you and your students.  You could make a topics list of your own!
