Erosion, Valleys, and Canyons

Can you imagine how long it would take you to dig out a canyon?

This lesson has 2 parts! First, you will learn a little bit about how water erodes the land, and set up an experiment to see if still-water or moving-water is better at causing erosion.

After you do the experiment, you’ll learn more about erosion, how it molded Earth’s surface, and how it created some of the interesting landforms we have today. Then, you’ll get to make a model of a canyon, and watch it form right in front of you before researching real-world canyons and valleys to find out how they formed!
