The Earth's Layers

How do scientists know the difference between a meteorite from space and a regular rock from the earth? Scholars read a passage and answer comprehension questions about the creation of the solar system. They extrapolate the main ideas to...

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...

Sal details the chemical and mechanical composition of the Earth's crust, mantle, and core layers—a substantial addition to your geology or earth science lecture.

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 phenomenon of the p wave shadow zone leads us to conclude that the waves are...

Can you show the parts of the Earth in less than a minute? This 50-second clip set to classical music, shows a cut away version of the Earth, exposing the inner core, outer core, mantle, and crust. It's short, sweet, and makes for a...

Students investigate the Earth's crust. In this geology lesson plan, students identify the materials made up of the Earth's crust and investigate the different kinds of soil.

Students study the layers of the Earth.  In this Earth's crust lesson students complete an activity, divide into groups and diagram and define given terms. 

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...

This lesson is designed to come after students have studied about the four main layers of the earth. They may relate the size of the sections to known objects such as the mantle to the size of a grapefruit and the outer core to the size...

What lies beyond the ground beneath our feet? Young geologists learn the four main layers of Earth with an engaging puzzle set. The interactive illustrates each layer, and users must place them correctly before they can progress to the...
