The Creation of the Grand Canyon

We have been busy studying all about weather, erosion, and deposition and how they all work together.  To help the students understand WED we went back in time millions of year ago to what the Grand Canyon looked liked before it became a canyon.  We discussed how the Colorado River has helped form the Grand Canyon.  The students built a replica of a plateau and then rain a river through it to get a better understanding of how the Grand Canyon was formed.  Students were able to see weathering, erosion, and deposition taking place!  What a great learning experience for the students!

Having meaningful discussions!



This activity really helped students to understand how weathering, erosion, and deposition work together to wear away Earth's surface.  They were also able to see how deposition builds new landforms!  Be sure to ask you child which new land from they see in the after picture!
