This link is a good and simple representation of the layers that make up the Earth’s Structure. This is an easy and interactive way to show the layers of the Earth.
This web link can be used in a number of ways. One way to use this web link is to make it the end of an introduction to a lesson. Using this as a closing introduction activity can help students build background knowledge before the next class period, where the layers will be broken down for a closer examination. Another is to build a worksheet around the layer facts that the web link brings up and use it to build students understanding of the Earths Structure.
