Erosion and Wetlands

Posted by Laurie Sullivan at 6/6/2010 7:00:00 PM

Second grade students learned about erosion and the role wetlands play in slowing down erosion. I shared with the students that when my sister and I attended UCSB, some of the nearby homes had problems with erosion. They also learned how wetlands can filter the water, up to a certain point. The students really enjoyed using our Wetlands Enviroscape Model, purchased with funds from our NASA Explorer School grant.
