Description: 

Take a hard-boiled egg and crack its shell. Does the egg remind you of anything? The Earth, perhaps? The egg could be seen as a tiny model of the Earth. The thin shell represents the Earth's crust, divided into plates; within the shell is the firm but slippery mantle. Move the pieces of the shell around. Notice how the shell buckles in some places and exposes "mantle" in other places. The same thing happens on Earth, but on Earth, this activity results in the formation of mountains, earthquakes, and new ocean floor. This activity lets you manipulate tectonic plates. Pull the plates apart and push them together and watch what happens to the Earth.
