In this lesson, students analyze primary source documents in an effort to answer the central historical question: Why did many Americans oppose the Vietnam War? First, students view 2 anti-war images and a timeline of anti-war events. They fill out a graphic organizer and formulate a hypothesis that answers the central question; discussion follows. Students then read 2 documents: a speech by Martin Luther King, Jr. and John Kerry’s testimony before Congress. For both, they complete questions on a graphic organizer. Final class discussion: Why did anti-war sentiment grow? Did only college kinds participate? How do you think supporters of the war might have responded?
