Divide students into small groups of three. The Mercator projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course. The new map was well-suited to nautical navigation since every line on the sphere is a constant course, or loxodrome. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. John Paul Goodes attempt, known as the Goode Homolosine Projection, took this concept a step further by adding interruptions at strategic locations to help reduce the distortion of continents.

Landmasses and seas are more accurately proportioned than in traditional projections. This is the map that we see in classrooms all over the world. This distortion gets exponentially worse as you approach the poles. The Mercator was devised by a Flemish cartographer in 1569. Fortunately, cartographers have the training to minimize these issues. This hands-on approach is a fun way to learn how the shape of landmasses shift as the projection changes. Read More: Earth Actually Has Four North Poles.
