Twelve self-contained history escape activities across three grade bands. Students open clues, weigh evidence, and crack four locks each — building U.S. history knowledge and critical-thinking habits at the same time. No logins, no prep, no data collected.
The Declaration, the flag, the growth of liberty, and why we celebrate — told through clear clues and a "prove it" habit.
Primary-source reading, cause and effect, ideal vs. reality, and evaluating historical claims and sources.
Enlightenment philosophy, the ratification debate, historiography, and rhetorical analysis of founding documents.
Every activity is a single self-contained HTML file. The only outside request is Google Fonts (removable for zero-egress hosting). Progress lives only in the browser session.
