Today, we started to learn about planet Earth in more detail. We already know that we orbit the sun and we are the third planet from the sun. Today we looked at the inside of the Earth and discovered it is made up of four main parts: the inner and outer core, the mantle and the crust.
The inner core is solid iron and nickel while the outer core is molten (liquid) and moves around. The mantle is the thickest part and gives the planet its weight. The crust is the thin layer on top that we live on.
We made models using Plasticine to to show each part.
