Mr. Corwin does a nice job summing up Lesson 1:
We have been working with primary and secondary sources.
Primary sources are original records from the past recorded by people who were:
Involved in the event, witnessed the event, OR knew the persons involved in the event.
Examples include artifacts, autobiographies, maps, letters and speeches.
Secondary sources are made at a later time.
They include written information by historians or others AFTER an event has taken place.
Examples include textbooks, history books, charts and graphs.
