Students will launch the local history investigation by using historian routines to sort and compare source sets, make an initial corroboration claim about a community event, and connect that event to people, places, or traditions they notice today.

Students will refine a focused local-history investigation question, test a tentative claim against multiple source types, and submit a historian-style methodology checklist/poster that explains which sources they will use, how they will corroborate evidence, and what context they need to track before moving into poster creation.

Students will present their two-sided evidence posters in a Historic Huddle Walk, gather feedback from classmates and the public library partner, revise key parts of their source collage, timeline, and CER conclusion, and submit a final poster that shows how corroboration and context shaped their understanding of community change over time.
