This is literacy based unit plan that beings with a compelling question: Was slavery the primary cause of the American Civil War? This comprehensive unit contains four supporting questions that build on the compelling question. Students will analyze various articles and sources of information to ascertain a position on the topic. All this builds toward answering the compelling question in a timed essay (which contains a rubric). Students will use SOAPS to analyze documents and primary sources (there is one Image Based Question). There is no key with the unit because much of it revolves around reading, analysis, and written response. The unit plan can be broken down by the supporting questions on a day by day basis (4 days), and then students would be assessed on the final day with the comprehensive essay. This is a rigorous unit that allows students to examine historical perspectives, while formulating their own theory on the subject of what caused the American Civil War. The unit plan comes with suggested video resources examining the compelling question (all video sources are free, and on You Tube or Hippocampus). The articles in the unit are written by various authors and have been posted on the internet. The SOAPS strategy is used frequently in this unit to allow students to gain understanding of sources, and how to correctly process information and point of view (a video clip on You Tube is provided, as well as the actual SOAPS rubric). This unit can also be assigned as homework for students to do on their own (if the teacher prefers not to use it in class). When students finish with this unit, they will have examined various critical aspects of the American Civil War; and the causes of this horrible conflict. This is an excellent product to use when studying Antebellum America, slavery and sectionalism.
