Is Earth like a hard-boiled egg?

Kia ora

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 the link to the science experiment report we wrote with the teacher at the end of our experiment.

Structure of the Earth

Kia ora,

We are learning about the structure of the Earth.

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

Crust, Mantle, Outer core, Inner core.

Facts about each layer:

Crust -The crust is 8-40 kilometres thick and is Solid but Brittle, it is the first layer.

Mantle - The mantle has a thick rock but is soft, squishy and hot, it is the second layer.

Outer Core -The outer core is as hot as an oven that is at the highest level, it is the 3rd layer.

Inner Core -The inner core is hotter than all of the layers but it is solid

because of the pressure being push down on it this is the fourth layer.

Our group - Brooke Briggs, Me and Piata.

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

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.
