We have been learning about the four layers of the Earth. With a little help from Mr. Lee, we have learned all about the Inner Core, Outer Core, Mantle and Crust!
Students began this project with red dough to shape the Inner Core. This layer of the Earth is almost as hot as the sun and it is made from solid iron and nickel. Then, they carefully covered the inner core with orange dough, creating the Outer Core. The Outer Core of the Earth is made from very hot, liquid iron and nickel.
Students then used yellow dough to form the thickest layer of the Earth, the Mantle. The Mantle is not all liquid, nor is it all solid. We tell the kids to think of it as a "Jello" like substance that has some movement, but doesn't flow.
The thinnest layer of the Earth is the Crust. We walk around on the Crust every day! The kids used brown dough to represent the Crust and then they got busy covering their Earth with continents and oceans!

After their Earths were complete they took dental floss and sliced them in half! Each partner was able to keep one half to help them remember the:
