This unit plan summarizes an 8-week unit on changing societies for an 8th grade Humanities class. The unit focuses on how exploration impacted indigenous societies in Australia and North America. Students will examine changes triggered by exploration and compare indigenous cultures before and after contact. The key assessment asks students to write a script for a play demonstrating changes from exploration and explain the intended impact on the audience. Learning activities include research, documentaries, timelines and maps to develop understanding of indigenous cultures and changes over time. Reflection on the unit noted some students struggled with comparing two cultures simultaneously and it may have been better to focus on one at a time.
