Layers Of The Earth!!!

WALT(we are learning to...) make a model of the earth out of play- dough.

Why are we learning this?
So that when we learn about Natural Disasters we can use our knowledge of the layers to understand them better!

What other subjects at school can this help with?
This can help in topic and science and learn about the earth around us and the layers.

Crust (seven tectonic plates):
Did you know that the crust is made up of the tectonic plates which there are seven in the whole of the world! Another thing to hear about is that it contains continents and seas. It is 15-75km thick.

Mantle(upper mantle and the lower mantle):
Did you know that there are 2 parts of the mantle and those 2 mantles are the upper mantle and the lower mantle. Did you know that the upper mantle is 400km thick and it would take days and days to dig through the earth. Are you aware that the lower mantle is 2300km thick. The lower mantle is made out of iron and magnesium. It is more dense than the upper mantle. The upper mantle is made out of silicates.

Outer Core(liquid):
Did you know that the outer core is 2300km thick. Are you aware that it is made out of liquid and sulphur... It is also made out of nickel.

Inner Core (solid):
Did you know that the inner core is made out of sulphur just like the outer core. It is also made out of iron and nickel. The inner core is solid. The temperature is 6650 degrees.


  1. I like the way that I used all of the information from my sheet even though I wasn't here when they did the note- taking I had help from a friend and her name is Anais!
