This learning resource focuses on the discovery of the Rosetta Stone, guiding students to analyze and compare the credibility of both a primary source (a soldier's diary from 1799) and a secondary source (a textbook excerpt from 2024). Students engage in structured discussions to assess the reliability of each source in understanding the event's details. They will use a credibility checklist to evaluate strengths, the influence of time on perspective, and formulate a group's claim regarding which source provides a more reliable understanding of the physical act of discovery. The resource also encourages reflection on the differences between modern interpretations and eyewitness accounts, culminating in a challenge task that invites students to project future historians' views on contemporary historical narratives.
