In this lesson, students analyze primary sources in an effort to answer the central historical question: Why did the U.S invade Cuba? The teacher streams a short film (link included) while students take notes as to possible reasons for the invasion. Students then read the following: 1) song lyrics of an anti-Spanish propaganda a song written after the Maine sinking, 2) a telegram sent by Fitzhugh Lee, U.S. Consul-General in Cuba, and 3) a Senate campaign speech from Albert Beveridge. For each, students complete a graphic organizer and guiding questions. A final class discussion goes back to the original class hypotheses and determines which ones are most supported by the evidence.
