Using Different Models of Earth

In this activity, learners explore how the shapes, sizes, and distances of land masses appear differently on two different models of Earth: an icosahedron and a flat map. First, learners find the shortest distance between New York and Paris using a globe map and piece of string. Then, learners assemble an icosahedron model of the Earth and answer questions comparing the model to a flat map. Finally, learners identify different antipodes and determine if antipodes are easier to identify on icosahedron or flat maps. This resource contains links to materials that explain how the icosahedron is the basis for new models being developed for global weather prediction.
