Objective

By the end of this lesson, the student will be able to create a clay sculpture that represents a natural landform, while understanding the geological processes involved in shaping the Earth's surface.

Materials and Prep

• Clay (air-dry or modeling clay)
• Reference materials about landforms and geological processes (books, websites, etc.)
• Work surface or mat for sculpting
• Basic sculpting tools (if available)

Before starting the lesson, the student should have a basic understanding of different landforms and the processes that shape the Earth's surface. This can be achieved through prior reading or discussions on the topic.

Activities

1. Create a list of different natural landforms such as mountains, canyons, valleys, and plateaus.

Discuss the formation of each landform and the geological processes involved, such as tectonic movements, erosion, and weathering.

2. Choose a specific landform to sculpt using clay.

Encourage the student to research and gather visual references of the chosen landform to guide their sculpting process.

3. Begin sculpting the chosen landform using the clay, focusing on capturing its unique features and characteristics.

Emphasize the importance of paying attention to details and the geological forces that shaped the landform.

4. Reflect on the sculpting process and discuss the geological significance of the created sculpture.

Encourage the student to explain how their sculpture represents the natural landform and the geological processes involved in its formation.

Seventh Grade Talking Points

• Landforms are the natural features of the Earth's surface. They can be formed by processes such as erosion, weathering, and tectonic movements.

"Let's imagine the Earth's surface as a canvas, and the natural forces as the artists shaping it over millions of years."

• Mountains are formed by the movement of tectonic plates, which can push the Earth's crust upward to create towering peaks.

"Think of mountains as nature's sculptures, crafted by the powerful forces beneath the Earth's surface."

• Canyons are created by the erosive power of rivers, gradually carving deep channels into the Earth's surface over time.

"Picture a river as a sculptor, patiently carving through rock and soil to reveal the hidden beauty of the land."

• Plateaus are elevated flatlands that have been uplifted by tectonic forces and shaped by erosion over long periods.

"Imagine plateaus as ancient canvases, slowly shaped and textured by the elements to create breathtaking landscapes."
