Objective
By the end of this lesson, you will be able to understand the concept of erosion and its impact on the Earth's surface using Lego models.
Materials and Prep
Materials needed: Lego bricks of various sizes and colors
Prep: None
Activities
1. Build a Lego model of a hilly landscape, making sure to include different layers of soil and rocks.
2. Use water to simulate the effect of erosion on the landscape by pouring it over the Lego model and observing the changes.
3. Discuss the impact of erosion on real-life landscapes and how it shapes the Earth's surface.
Seventh Grade Talking Points
- "Erosion is the process of wearing away soil and rock by natural forces like water, wind, and ice."
- "When we poured water over the Lego model, it represented how rain and rivers can erode the land over time."
- "Erosion can create valleys, canyons, and other landforms that we see on Earth."
- "By understanding erosion, we can appreciate how the Earth's surface changes and evolves over time."
