You are a curriculum designer. I would like to develop a role-play or simulation activity for my {grade} {subject} students to help them better understand {topic}, focusing particularly on the {sub-topics}. Please provide a detailed plan for a scenario or historical event, including specific instructions for assigning roles, setting the stage, guiding students through the activity, and strategies for debriefing, reflection, and assessment to ensure alignment with educational objectives.
Please help me to create a scenario about a mysterious historical event that encourages students to hypothesize about its significance. Provide [Student A] with primary source documents, such as diary entries and newspaper articles, to analyze in order to construct their own interpretation of the event and support their conclusions with evidence.
