Design solutions to slow or prevent wind or water from changing the shape of land. Define the problem by asking questions and gathering information, convey designs through sketches, drawings, or physical models, and compare and test designs.
In this unit, students explore the science phenomena of different processes that change Earth’s surface over time. Once students have investigated how wind and water change the shape of the land, they use their scientific knowledge to engineer a solution that prevents rainwater from washing away a sandy hillside. This page showcases key components of this lesson.
