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.

Earthworms

Kia ora,

We have been learning about earthworms with Mrs Fletcher, we found some worms and put them in a plastic container, then we used a magnifying glass to count the segments on their body.

We needed to write complex sentences about worms.

1.  Worms like the dark better than the light.
2. Earthworms like the dark better than the light because the are safe underground.
3. Earthworms like the dark better than the light because the are safe underground and the birds will not get them.

I found it hard to find the facts. I found it easy to learn how many segments were on the worms.
