The Earth's Layers

Learning Objectives

At the end of the lesson, you will be able to identify and describe the four main layers of the Earth.
At the end of the lesson, you will understand the composition and physical state of each layer of the Earth.

What do you already know about the Earth's layers?

Mantle: The thickest layer composed of solid rock

The layer beneath the crust, consisting of solid rock and being the thickest layer.

Crust: The Earth's outermost layer

The thin, outermost layer of the Earth.

Outer Core: A liquid layer made of iron and nickel

The liquid layer beneath the mantle, primarily composed of iron and nickel.

Inner Core: The solid innermost layer made primarily of iron and nickel

The solid, innermost layer of the Earth, primarily made of iron and nickel.

Summary

The Earth can be divided into four main layers: the crust, mantle, outer core, and inner core. Each layer has unique characteristics and composition.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
