One of my favourite areas of science to teach after Biology was Earth Science. I loved seeing the moments of wonder as children understood a little more about the planet that we live on and how it works to create the environment that is needed to form life and for us to live. When I taught it one of the first things I started with was understanding what the planet is made of especially in terms of the layers of the Earth. This 3D Layers of the Earth Model was an easy no mess activity that could be done to create a quick model that the kids could then use to extend their knowledge in their workbooks further.

I liked to mix up the different methods we looked at and represented the layers of the earth as children learn in different ways. This pie section model is a low mess activity and was a piece of homework I would set as it was easy to make, needed little resources and they could use the models and notes we had made in class to work on it.

Whether you are a parent that has been set create the Layers of the Earth for homework, a homeschooler who is teaching your own children about this or a teacher looking for some activities that could be used in the class or as a homework activity on Layers of the Earth this is ideal.

Making your Layers of the Earth Section Model

  1. Print out the Earth Layers Template.Three dimensions layers of the earth section model to make - ideal for earth science, work out the scale and produce a representation of the different layers of the earth.
  2. Cut out around the edge of the net.
  3. Score along the internal lines.

Now time for some maths – when you print out the model it will vary in size depending on the size of your paper – this means that this model can be enlarged or reduced depending on the size. Because we want an accurate model we need to know some Layers of the Earth Facts. I used to get my students to research this using the Earth Science books in the classroom or for homework to start to make their models accurate.

This Super Earth Encyclopedia from DK Smithsonian is a great resource for exploring earth science with kids. I love the detail of the pictures, as well as the information, contained giving you a resource that will last a while. Perfect for home learning or in the classroom.

They needed to know – The size of the inner and outer cores, the size of the mantle and of the crust of the earth.

For your information – the Inner Core is 1255km, the Outer Core is 2221km, Mantle 2900km and the Crust between 6 and 11km which is around 6378 – 6384 km in radius

Calculating the Size of the Layers of the Earth for the Model

As I said we want the model to be accurate so measure from the point of the triangle to the end of that section – that is equivalent to the radius of the earth.

To calculate the length of each section of the model you need to work out what 1km on your model will be. So that you can then multiple each section by the 1km to find out the size you need.

For example, my model had a length of 105mm along the edge of the triangle when printed out – I then did the calculation 105/6384 to get the 1km length which was 0.016mm

For each section then calculate the distance on your model –

Inner Core : 1255 x 0.016 = 21mm ~ Outer Core : 2221 x 0.016 = 37mm ~ Mantle : 2900 x 0.016 = 48mm ~ Crust = 8 x 0.016 = 1mm

You will need to work this out for your model as your printer and paper will be different than mine.

Creating the Layers of the Earth

  1. Starting at the point measure out the distance for the Inner Core and mark on each line.
  2. Join up the points in a line.
  3. Now from this line measure out the distance for the Outer Core and mark on each line.
  4. Repeat the joining up and then measure out the Mantle and Crust the same.
