A Journey to Earth's Center

We can't dig a hole through the Earth, so how do we know about the layers beneath our feet? Scholars learn about layering through hands-on exploration of common materials. They study the characteristics of each layer and apply their...

Young scientists piece together the geological puzzle that is the earth in the third and final lesson of this earth science series. With the help of numerous multimedia resources and a series of engaging hands-on activities, learners...

Salman Khan goes into detail about the layers of the Earth. He provides names and general numbers about depths and composition.

Sal details the chemical and mechanical makeup of the crust, mantle, and core layers of the earth. A strong addition to your geology or earth science lecture.

How is the Earth like an onion? In this video from PBS Digital Studios, viewers first learn the different layers of Earth and their properties. In addition, they hear how these layers came about, starting with the Big Bang theory and the...

Playdough has reached a new level. This clay-motion video demonstrates continental drift, faults, volcanoes, and mountain formation. If you don't show this clip perhaps you could employ the concept and have your class make an amazing...

The big question is, how do we know about the composition of the earth's core? Sal explains that at 105 degrees from the source point of an earthquake the phenomena of p wave shadow zone leads us to conclude that the waves are traveling...

How much do you really know about our planet? Middle schoolers build up their prior knowledge about Earth, its placement in the solar system, its composition, and important geological vocabulary with an introductory earth science lesson.

Get your hands dirty with a set of earth science activities! Class members delve into a hard-boiled egg to find the similarities to the earth's layers, create a papier-mâché model of the earth, craft a simulation of the earth's...

What a great way to incorporate hands-on learning while teaching about the earth's layers. The class observes an overhead transparency (linked in Included Materials) as they create their own model Earth using different colors of clay....
