This session invites educators to step into the role of advertisers to explore how propaganda works by first selling the unsellable. Participants begin with a hands-on activity creating an appealing advertisement for a deliberately undesirable property, identifying techniques such as selective truth, emotional appeal, exaggeration, and omission. The session then connects this experience to the Last Best West settlement campaign, examining how government and railway advertising promoted Western Canada while omitting Indigenous presence, environmental realities, and settler experiences. Designed for upper elementary and secondary Social Studies classrooms. Educators leave with ready-to-use lesson structures and discussion prompts to help students question sources and recognize propaganda.
