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.

November 3rd Behind School
On November 3rd, the 3rd-5th grade went behind the school and collected data for the first time since we created our questions. We found our study sites and took pictures and pin-pointed it on our GPS. In one of our study sites we had an alive tree and a dead tree, but in the other site we only had a dead tree.The biggest cottonwood tree that we saw had the circumference of 246cm.We wrote about the cottonwood tree and drew pictures to follow. Most of the deciduous trees didn’t have their leaves.
When we took our soil sample the soil was really clayish and we had a hard time getting a good sample.The ground was very crunchy and it was on a very cold sunny day.
We had a lot of fun on our first data collection field trip.
Please give comments and questions.

Year Long Study Questions
These are our year long study questions. It took us along time to agree on them.
1. What types of soil are in Gustavus?
2. What types of soil do certain plants need in Gustavus?
3. What needs to be in the soil for certain types of plants to grow?
4. What do plants do in the winter?
5. How many invasive species are at our study sites?
6. How many species of native plants are at our study sites?
