An infograph showing the chemicals that are present in Earth's crust.

Young students are introduced to the complex systems of the Earth through numerous lessons on its natural resources, processes, weather, climate and landforms. Key earth science topics include rocks, soils and minerals, water and natural...

In this activity, students will make observations then construct a "sample" model representation of the Earth's layers. They will compare and contrast the movement and material in each layer explaining the location and what it contains.

From ABC News in Science, Will Dunham's article covers research connected to the discovery of a chunk of Earth's crust found in Greenland which possibly dates over 3.8 billion years.

Earth Really Rocks is a teaching unit for Grades K-3. It approaches the study of rocks from an energy perspective, looking at how gas and oil are formed underground, as well as at sedimentary rocks and the structure of the Earth's crust....

This is a website not only on the mantle but also about all the layers of the earth.

Explore deep underground and deep in the ocean to discover what lies beneath the surface. Don't stop until the final destination: the core of the Earth.

[Free Registration/Login may be required to access all resource tools.] A complete, web-based, multi-media textbook covering a wide variety of Earth science concepts for middle grades.

This site provides a very interesting overview of our home planet, Earth. Content includes a focus on the atmosphere, the pull of gravity, and the active surface.

Labeled diagram of a section of the Earth's crust.

In this lesson, you will learn about how the Earth formed as well as the composition and structural layers of the Earth's interior.

In this site learn about the structure of the Earth, the Earth's crust, and the usefulness of the earth materials. It contains many illustrations and 15 interactive activities.

Take a look at the layers that make up our Earth: inner core, outer core, mantle, and crust. Then have fun making a model of the Earth's interior that you can eat up.

Through five lessons, students are introduced to all facets of the rock cycle. Topics include rock and mineral types, material stresses and weathering, geologic time and fossil formation, the Earth's crust and tectonic plates, and soil...

[Free Registration/Login Required] An informational text about Pangaea, the one continent that became the current seven continents. A question sheet is available to help students build skills in reading comprehension.

As an overview of the online exhibit on earthquakes, this site discusses the various sections inside the Earth. The crust, the mantle, and the core are each individually discussed.

This is a website to learn not only about the inner and outer core, but also about the crust and the mantle of the interior of the earth.

Topics covered in this slideshow include the Earth's interior, seismic S- and P-waves, the crust and mantle, phase boundaries encountered by seismic waves, the Earth's internal heat, gravity and density, gravitational anomalies, the...

Matching game on the earths core and crust. Students test their knowledge and learn what is below the earth's surface.

The interactive resource examines the plate tectonics, magnetic reversals, and continental drift of the Earth. An animation of the Earth's continental drift over the last 750 million years is included.

An in-depth look at how isostasy works and the processes taking place during glaciation and the melting of glaciers. Looks at gravity and the effects of density differences within the crust and mantle, and at Earth's magnetic field and...

The Franklin Institute has provided a demonstration that theorizes how the earth's crust was formed. This is a lesson plan that needs only a few materials.
