Why do we make models in science?
Trying to study or look at something to big or to small
In our case, the earth is to big to study without making a model of it. So we need to scale it down...
Crust = 0-22 miles
Mantle = 22-1790 miles
Outer Core = 1790-3160 miles
Inner Core = 3160-3954 miles

How do you make a scale model?... want to make a model of Earth's interior
1) How big is the model? 3954 miles - 0 miles = 3954 miles
2) How much space to you have? find center of paper and measure to side with shortest distance (~10 cm)
3) Scale = how many miles in each centimeter
4) Use scale to make each measurement listed smaller.
5) Mark these measurements and use compass to make circles to model Earth's interior.
