Product Description
Many things in science at first seem confusing (what’s the difference between the lithosphere and asthenosphere?!?!), but what's usually missing is a good explanation. The purpose of this graphic organizer is to get your students to fully understand what the physical layers and compositional layers of earth are, along with the similarities and differences between the physical layers and compositional layers of earth.

This powerpoint shows you and your students step-by-step how to create the graphic organizer, which they will make with their own hands, making it a memorable and valuable learning experience about earth's compositional layers and physical layers. And they’ll even be able to understand the difference between the lithosphere and asthenosphere.

What each student will end up with is a very cool side-by-side comparison of earth’s compositional layers (crust, mantle, core) and it’s physical layers (lithosphere, asthenosphere, mesosphere, outer core, inner core).

After the title slide (“Earth’s Compositional Layers & Physical Layers") your students will be directed to fold the ends of their paper in to the center. After removing a portion of the top, we’ll have an area we can write down what we mean by “compositional layers”. It’s important to start with that and not just assume that everyone just knows what it meant by “compositional layers”.

Following that we’ll put a scale from 0km - 6,000km down the left side representing depth from earth’s surface to it’s center, which will help us locate where the crust, mantle, and core are.

After marking where each compositional layer begins and ends (crust from 0-35km, mantle from 35-3,000km, and core from 3,000-6,000km), we’ll cut those lines, forming little doors that open to write facts about the crust, mantle, and core.

With the composition layers finished on the left side, we’ll now switch to the side with earth’s physical layers- which includes the lithosphere, asthenosphere, mesosphere, outer core, and inner core- on the right, beginning with a good definition of 'compositional layer' at the very top.

After marking where each physical layer’s boundary is (lithosphere 0-60km, asthenosphere 60-700km, mesosphere 700-3,000km, outer core 3,000-5,000km, inner core 5,000-6,000km), we’ll cut those lines, again forming the little doors that we’ll open to write facts about each layer (lithosphere, asthenosphere, mesosphere, outer core, inner core).

The last optional slide gives your students the chance to add color to their graphic organizer. It really doesn’t take much time to do, but doing so does add a lot to the project, and gives your students one more reason to differentiate the lithosphere from the asthenosphere (the lithosphere they’ll color brown and the asthenosphere they’ll color orange).li
