This project examines the historical thinking concept of Cause and Consequence through the study of Prime Minister Robert Borden’s wartime rhetoric during the First World War. Using a 1914 parliamentary speech and a photograph of him addressing troops at Seaford Camp, the project models how historical thinkers analyze motivations and outcomes behind political messaging. A primary source analysis chart scaffolds student engagement by breaking the speech into manageable sections. This prompts learners to identify causes behind Borden’s arguments and predict potential consequences for Canadian society. Grounded in scholarship on historical thinking, the project offers a pedagogically sound approach for Grade 10 CHC2D classrooms, encouraging students to move beyond description toward critical interpretation of how leaders shape, and are shaped by, historical events.
