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.  In 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.

Learners 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 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.

Students study information about the Earth's crust, mantle, and core by construct models using playdough. Students diagram and label the layers of the Earth on paper.

Students discern that the earth is made up of different layers.

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.
