Signal in the Archives

Source evaluation & media literacy · Grades 6–8

Premise: A viral post makes a dramatic but false claim about the signing of the Declaration. Students compare a primary-source record, a national archive, and an anonymous forum, catch a fabricated quote, and separate the true part of the claim (adopted July 4) from the false part (a single July 4 signing ceremony).

Students weigh the archive entries and solve four locks (a fact-check MC, an adoption-day lock, a weakest-source word lock, and a red-flags evidence sort). Each lock reveals a short reasoning explanation. The answer key is not shown on this page.

Skills & standards alignment

Content is aligned to these strands; the activity is a supporting resource, not a verbatim standard statement:

Texas TEKS · Social Studies skills (Gr 6–8): differentiate between valid and invalid sources and detect bias; distinguish primary from secondary sources.
Texas TEKS · Social Studies (Gr 8, U.S. History): understand the adoption and signing of the Declaration of Independence.
Common Core ELA/Literacy · RH.6–8.8: distinguish fact from opinion/reasoned judgment and evaluate the reliability of a source.
Reasoning habit: distinguishing supported conclusions from unsupported guesses ("prove it from the clue").

💡 Teacher tip: The "thousands of shares" decoy is the core media-literacy lesson: popularity is not evidence. Connect this to how students evaluate claims they see online today.
