The adventures at Shelburne Farms!

On Thursday the entire 4th Grade went on a field trip to Shelburne Farms!  It was so cold but we had fun learning about soil and rocks!  We were there kicking off our study of geology!  Geology is the study of rock types, the rock cycle, and changes in the earth's landscape.  We learned about the changing landscape at Shelburne Farms.  We learned about the landscape by observing soil and rocks on the property.  Some soils are more acidic than others because of the rocks found in soil.  On the property different locations had different levels of acid!  We used a soil test that measures pH.  A pH level tells you if the soil is gonna be good for gardening, pastures, or simply left as green space.  A blue color on the test means the soil is neutral.   By the beaches we could see different types of rock.  Many of the beaches are covered in shale.  We could also see how the bedrock has moved under the soil, sometimes two different rocks collided and moved over or under each other.  We also could see how the lake is causing erosion to the landscape, wearing away land and creating cliffs.   Lastly, at Shelburne Farms you can find metamorphic, sedimentary and igneous rocks!  We can't wait to learn more about Geology!


Today, Shelburne Farms came to us to teach us about Teamwork...ask your child about the challenges they completed in their groups!
