# How to Make a Model of the Earth's Layers for a Sceicne Fair?

Making a model of the Earth's layers for a science fair is relatively easy. First you need to figure out how big you want it to be, I would suggest either inches or centimeters. You will also want to use three different colors to represent the 3 layers. The inner layer is the core of the Earth, with a scale of 1:1,000, the diameter should be 6.8. The next layer, or the Mantle, should be a thickness of 2.9. The outer layer, or the Crust ranges in thickness from 5 to 50 kilometers, so telling you how thick to make it is difficult, but it should be a thin layer.
