Earth's Layers

Students examine the layers of the earth and the basic composition and thickness of each. Using construction paper, each student models the layers of the earth.

Students identify the interior layers of the Earth and analyze a diagram.  For this Earth's layers lesson students create a model of the Earth's interior. 

What causes earthquakes? Second graders learn about stresses from plate movement with a set of hands-on activities. After tracing fault lines on a map with yarn, class members create a paper plate model of Earth to show its layers and...

The deeper you go into the Earth, the hotter it's going to get. Discover what is actually beyond the Earth's crust and why it gets hotter and hotter the further you go.

Why can't we dig through to the other side of the Earth? There are many layers and lots of heat, so the job is impossible. Watch a video that describes and explains each layer of the Earth.

Students identify the geological layers of the Earth. They graphically depict each layer's characteristics. Students label and develop a color key for their exhibit. They create a down-to-Earth 3-D display with Erasable Markers.

Students use construction paper to model the layers of the earth.

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...

Students gain an understanding of the methods used to explore the earth's surface. Students create a time line leading to the first satellite image of the Earth that includes the various methods utilized to observe the earth's surface.

Students explore salt and fresh water. In this water lesson, students investigate the amount of Earth covered by water. Students compare the amounts of salt water to fresh water. Students create a visual representation to aid comprehension.
