The Mind-Blowing Map Quiz is designed to help students understand how Mercator projection maps distort our view of the world. It does this by asking relational questions like "how much bigger is Australia than Alaska?" and "how close are Russia and the United States?" A few fun facts are thrown into the explanations of each answer.
Applications for EducationCan You Make an Accurate Map? is a good video to show after students have played The Mind-Blowing Map Quiz. The video provides a concise explanation of why Mercator projection maps don't accurately represent the size of things near the poles but are none-the-less used in many applications.
For more ideas for lessons about map projections take a look at National Geographic's hands-on lesson plan for teaching map projections or this lesson from Leventhal Map (hosted by Boston Public Library) that incorporates the use of Google Earth.
