Lesson Plan Material - “Encounters and Change: Expanding Perspectives on Natives and Colonists in 17th Century Plymouth"

Maybe this is helpful; maybe it is not. It's just anecdotal, so take it for what it's worth:

In 2004, we attended the workshop listed in the title above. We were listening to a lecture from a renowned Pilgrim scholar, when someone asked why the pilgrims always wrote such wonderful accounts of spring and summer, but never about fall. When the scholar indicated that he did not know, a fellow attendee suggested that maybe the pilgrims viewed spring and summer as seasons of hope, but fall was a reminder that they had better put up as much food for the winter as possible or face a grim season of starvation.

Maybe this would be valuable to have high school students think about.
