Each four-page packet includes two learner pages, an answer discussion, and source links with facilitator notes. Print pages 1–2 for the activity, then use pages 3–4 to compare explanations. The PDFs use US Letter with generous margins; choose Fit when printing on A4. Color is optional because text labels carry the meaning.
A pencil and the printed pages are enough. Allow about 35–45 minutes, individually or in a small group. Atlas visits are optional extensions, and the complete activity is also available as readable web text.
Print and share the complete guides with attribution. When sharing online, link to the activity page so readers can find the source trail and the current PDF. Original activities and diagrams by The Last Transmission, reviewed October 11, 2026.
