Quirky History: The Map That Lies to You Mercator Map Investigation | West Wing

Quirky History: The Map That Lies to YouMercator Map Investigation | Inspired by The West Wing | Grades 6–10

On the map hanging in classrooms everywhere, Greenland looks about the same size as Africa. It isn’t even close.

In this Quirky History investigation, students uncover why one of the world’s most familiar maps gives us a surprisingly distorted picture of Earth. Students explore the Mercator projection, why it was created for navigation, and why landmasses appear increasingly exaggerated as they move farther from the equator.
Rather than simply learning that the map is “wrong,” students investigate a much more interesting question: Why would we continue using a distorted map? Through real-size comparisons, projection analysis, and a collaborative investigation, students discover that every flat map makes compromises—and that the best map depends on what you need it to do.

- Sub Plans

Students culminate the lesson by building a Mercator Map Investigation with at least four entries explaining distortion or revealing surprising size comparisons. They also add a “Maps Today” example showing a modern situation where accurate relative size matters and share the comparison that surprised them most.
