From the crust we inhabit to the core that impacts Earth's magnetic field, each layer has its own significance and mysteries that draw scientists globally.

Initial Activity

To kick off the lesson, show a short video (3-5 minutes) featuring an animation of Earth's formation and its main layers. Then, pose this thought-provoking question: 'How do you think life on Earth would change if we didn’t have a solid crust?' This will help ignite students' curiosity about the topic.

Development

Duration: (50 - 60 minutes)

The aim of this stage is to deepen students' understanding of Earth's layers through a practical and interactive activity. This not only consolidates their theoretical knowledge but also develops relevant job-related skills such as model building, research, teamwork, and presentation skills.

Topics

1. Formation of the Earth

2. Layers of the Earth: Crust, Mantle, and Core (Inner and Outer)

3. The Significance of Earth's Layers in Geology and Industry

Thoughts on the Subject

Encourage students to think about how knowledge of Earth's layers might influence their lives and future career choices. Lead a discussion on practical applications of this knowledge, which can range from natural resource exploration to civil engineering and disaster preparedness.

Mini Challenge

Building Earth in Layers

Students will create a three-dimensional model of Earth's layers using accessible materials like foam, clay, play dough, or papier-mâché. This activity enhances practical understanding of the different layers of the planet and their distinct characteristics.

1. Divide students into groups of 4 to 5.

2. Provide necessary materials for each group: foam, clay, play dough, or papier-mâché, toothpicks, markers, and paints.

3. Explain that each group should create a model of the Earth, showcasing the crust, mantle, and core (both inner and outer).

4. Encourage groups to research the characteristics of each layer to accurately represent them in the model.

5. Guide students to use toothpicks for labeling each layer with important information about thickness, composition, and temperature.

6. At the end, have each group present their model to the class, explaining the layers and their characteristics.

Foster a practical understanding of Earth’s layers and their characteristics while developing teamwork and presentation skills.

**Duration: (30 - 40 minutes)

Evaluation Exercises

1. Describe the main characteristics of the Earth's crust.

2. Explain the difference between the upper mantle and the lower mantle.

3. What is the main function of the Earth's core?

4. How does knowledge of Earth's layers assist in exploring natural resources?

5. Create a labelled diagram of Earth's layers.
