Engineers frequently use scale models and computer simulations to test concepts without wasting costly resources. Constructing scale models of the Earth assists engineers in the design of instruments that help predict earthquakes.

Engineers also use small-scale models of our planet to understand the relative size of the Earth, model space flight orbits around the Earth, and predict how the Earth might change over time. To teach your little one about the layers of the Earth, students created a 3 dimensional model of the Earth using various colors of Playdoh.

As a result of this activity, students were able to demonstrate an understanding of the shape and physical makeup of the earth including core, mantle, crust, and oceans.
