Lesson Plan: Layers of the Earth

Subject: Geography

Duration: 30 minutes
Grade Level: Middle School (Grades 6-8)
Topic: Layers of the Earth

---

Objectives

By the end of this lesson, students will be able to:

1. Identify the three main layers of the Earth: the crust, mantle, and core.
2. Describe the characteristics of each layer and their importance.
3. Understand how the layers interact with each other.

Materials Needed

• Whiteboard and markers
• Projector and computer for presentation
• Printed diagrams of Earth's layers
• Student notebooks/pens

Lesson Outline

Introduction (5 minutes)

• Begin the lesson by asking students what they know about the Earth's structure.
• Write responses on the whiteboard.
• Introduce the topic by explaining that today we will learn about the three layers that make up our planet.

Direct Instruction (10 minutes)

1. Crust

   • Explain that the crust is the outermost layer of the Earth.
   • Discuss its composition (solid rock) and thickness (about 5-70 kilometers).
   • Mention that this layer is where we live and includes continents and ocean floors.

2. Mantle

   • Describe the mantle as the thickest layer, located beneath the crust.
   • Explain its semi-solid state, highlighting the flow of molten rock (magma).
   • Discuss its importance in tectonic plate movement.

3. Core

   • Explain that the core is divided into two parts: the outer core and inner core.
   • Discuss the outer core as a liquid layer made of iron and nickel.
   • Describe the inner core as solid due to extreme pressure, also primarily composed of iron and nickel.

Interactive Activity (10 minutes)

• Divide students into small groups.
• Provide each group with printed diagrams of Earth's layers.
• Ask groups to label the layers and write down key characteristics of each layer on the diagrams.
• After 5 minutes, have each group present their findings to the class.

Conclusion (5 minutes)

• Summarize the main points discussed about the layers of the Earth.
• Reinforce the significance of understanding Earth's layers in fields like geology, seismology, and environmental science.

Homework Assignment

Task: Write a short paragraph (5-7 sentences) about one layer of the Earth that interests you the most. Include at least two characteristics and why it is important.

Example Scaffold for Homework

• Layer of Interest: [Choose either Crust, Mantle, or Core]
• Characteristics: [List any two characteristics]
• Importance: [Explain why this layer is significant]

---

Answer Key to Homework (for Teacher Reference)

1. Crust:

   • Characteristics: Thin layer, composed of solid rock.
   • Importance: The layer where all life exists; includes landforms and ocean floors.

2. Mantle:

   • Characteristics: Thickest layer, semi-solid, and flows slowly.
   • Importance: Drives tectonic movement and volcanic activity.

3. Core:

   • Characteristics: Outer core is liquid; inner core is solid and extremely hot.
   • Importance: Generates Earth’s magnetic field which protects us from solar radiation.
