November 17 Behind the School

This was our first field trip with snow! The snow was crunchy, and it was sunny and cold. Brr! People were really cold! We learned that the ground was not frozen because the soil sampler was able to easily collect a soil sample. Our sample was really wet. After testing our soil for potassium, ph, phosphorus and nitrogen we compared it to our soil sample from Bartlett Cove. They were very similar. The only difference was that there was a little more phosphorus in Bartlett Cove. After looking at our results we decided to take another soil sample test from Bartlett Cove and behind the school.

One of us learned how to use the GPS and led us to all of our study sites behind the school. We all learned how to use compasses. We were told the directions by a classmate and we used our compasses to see if he was right. We tried to break a trail so that next time it would be easier to get to our sites.
