Is Earth like a hard - boiled egg?

We are learning about what the Earth is like on the outside and the inside. We used hard-boiled eggs as mini-models for the earth. We got to design our own continents and islands on the outside of the egg shell. At the end of the experiment we got to eat the egg!

Here is a link to the science experiment report we wrote with the teacher at the end of our experiment

Structure of the Earth

Hello,

We are learning about the structure of the Earth.

I learnt that the Earth is made up of 4 layers. They are:

Facts about each layer:

Crust - Is what we are standing on. The crust is the 1st layer on Earth. Now if you keep on
digging 40kms you can't reacth the mantle because it will get too hot for you to even touch
the Mantle.

Mantle - The Mantle is the 2nd layer on Earth. The Mantle is made out of rock but because
the Mantle is so hot the rocks melt then it gets all squishy and it's like liquid.

Outer Core - The outer core is liquid metal - also mostly Iron and Nickel. The outer core is
4000 - 6000 OC. It is totally liquid.

Inner Core - The very centre of the Earth is the inner core, which is mostly Iron and Nickel.

The inner core is solid because of the pressure pushing down on it from the layers above.

Our group - Ariana, Me and Teziah 

First we created a 3D image of the earth using clay and paint.

We then cut the shape in half to show the different layers. After waiting for it to dry, we identified
each layer by painting them in different colours.

Below are some pictures of our work.
