Student Post: Our field trip to Tryon Creek

  Last week our class went on a field trip to Tryon Creek. At Tryon Creek we first went to a classroom and learned about water sheds. Then we went on a hike in Tryon Creek's beautiful park. On the hike we study Tryon Creek's water to see if it was heathy. One of the ways we tested it was to use ph. We used ph by using ph strips that had different shades of orange on it and we put  the colored end in to the creek's water sample for thirty seconds. Then we pulled the strips out of the water and it changed colors, last we held are strips up to the package they came in that had a legend on it to figure out how heathy it is. We also did a experiment where we put a can on top of a mole hill and put water in it and timed how long it toke for the water to sink in. We did the same on normal ground to see which one was faster. The mole hill was faster because the water had some where to go. We also tested the oxygen in the water by taking a sample of the water and put a tube of chemicals in the water and the water would go into the tube and the tube would turn a shaded of blue. Then we held up the blue tube up to a scale that would tell you how much oxygen is in the water.
