Earth's Layers

Layers of the Earth

In our previous science and social studies units, students in 3K talked about the landforms and water above ground. Now we're exploring Planet Earth below the surface. After learning about the different layers of the Earth, kids used play dough to model the inner core, outer core, mantle, and crust. Then, they used markers to draw the different tectonic plates on the crust. 

A big thank you goes out to all those who made and brought in the play dough for our project! 


Each group started with the four different layers of the Earth
Students rolled the inner core into a ball and then wrapped it with the red outer core
Another group wrapping the outer core around the inner core
Then, students rolled out the orange mantle and blue crust
Finally, the outer crust was wrapped around the mantle
The 12 major plates were also drawn on the crust
And there you have it, the finished product!
Another group showing off their Earth 

The plates on the the Earth's crust are responsible for many natural disasters. Pick one of the disasters we covered in class (earthquakes, volcanoes, and tsunamis) and explain in detail how it happens in the comment section below.
