Three to four pages, using your textbook and lecture notes, evaluate important trends and themes in American history. Your assignment is to pick three trends that you notice throughout American history, from the Revolutionary War through 1945, and discuss how they have changed, endured, or even how they disappeared after a lengthy time. For full credit (up to the maximum of 40 points), students must demonstrate how these trends persist(ed) in American society, and give solid examples to back them up. These trends could be things like racism, economic opportunity, etc. Examine how they have changed, and how these trends can be seen in numerous specific points in American History.
