According to Larry Braile of Purdue University, the three main layers are the inner core in the center, the outer core outside the inner core, and the mantle, which is beyond the outer core.
We made a model showing the Earth's layers and found foods with similar layers. How to Dig a Hole to the Other Side of the World is one of my all time favorite children's science books.
The simple story tells the reader the hazards of digging a hole through the Earth, some handy items to have, such as a heat-proof suit, and what may be found in the dig as it progresses.
As the kids journey inside the Earth they learn about rocks, volcanoes and Earth's layers. Beginning with the birth of a hurricane, the film Earth from Space covers many Earth science topics we plan to revisit throughout our unit study.
Off the coast of Antarctica, when the ice freezes, saltwater sinks rapidly to the bottom of the ocean creating currents which help to regulate the Earth's temperature. Hurricanes actually drop the temperature of the ocean by releasing heat into the atmosphere.
Earth's Layers Lesson Plan in writing. Independent Practice/Activities: Allow students to explore their Milky Way bar and then create a diagram of the Milky Way bar and compare it to the Earth's layers. Enrichment Activities: Have students create a model of the layers of Earth using other candies. Date _____ Earth’s Dimensions Unit: Layers of the Atmosphere & Earth’s Interior INTRODUCTION: The Earth’s atmosphere is divided into 4 layers. There is a boundary where each layer ends and a new one begins and a name is given to this boundary – a pause. Overview. This interdisciplinary curricular unit focuses on the geology of the Earth. It contains background information, a detailed glossary, fun earth facts, literary references, and 20 hands-on activities for the classroom.
Everything is connected and the common thread is the Earth. Just like an egg, our Earth is broken into layers.
It is hottest at the core in the center. Liquid magma surrounds the core in the mantle, and although the crust varies in thickness, it is very thin in comparison to the diameter of the Earth.
An apple has a thin skin similar to the crust of the Earth. Inside, the core is shaped like a star, so the thickness varies just like the thickness of the Earth's layers vary at different locations. The pit of the plum was covered with a skin.
This is similar to the way the core is broken into an inner and outer core. Here is a cross section of the Earth showing the different layers. This drawing was made by me so the kids could see the relative thickness of each layer.
The dark ring around the outside is the crust. The red and orange show the mantle changes a bit with depth, and the yellow and white in the center are the inner and outer core. After looking at the food and drawing, the kids had the chance to create their own Earths with layers out of dough.
The salt, water, spices and oil were added to the crust to represent rocks, coal, gold, diamonds or animal bones that may be found in the thin layer.
Once the models were complete, they were sliced open so the layers could be seen. This model shows the inner core - yellow, outer core - red, mantle orange, and crust - green.

The earth is not simply one big ball of rock like you might imagine!
The planet, and the layer of gas round it, is alive in a geological sense. Here we’ll peel back the layers of the Earth, one by one.
