 Today I'm going to teach you about the layers of the earth. Our earth is made up of four layers The earth, the crust of the earth, the mantle, the outer core and the inner core. I also explain to my students that the volcanoes that take place happens on the crust of the earth. I also explain the difference that we cannot eat crust of the earth like we can eat the crust of the bread. When the children set up the inner core, I show them that this is crust, the mantle, the outer core and the inner core. The inner cores are very very hot substance that is red and that's why the inner core. I have cards to match my layers of the earth. So the children will take the earth card and they'll match it with earth. Then they match the crust. Beneath the crust, we have the mantle. And beneath the mantle, we have the outer core. Beneath the outer core, we have the inner core. So then I'd ask my children, so we start off with the earth. And what is that one? And the child will say the crust. I said, what is that? Mental. What is that one? Outer core and the inner core. Once they know the four layers of the earth, and for the older children that can read, they will now match the words. This one says inner core. That one is outer core. That one is the mantle, the crust of the earth and the earth. So now the children know about the four layers of the earth. We'll just go over it again. Our earth, the crust of the earth. The mantle, the outer core and the inner core. Thank you.
