At my first station we tested water for different metals and chemicals such they were Hardness, chlorine, iron, and copper. As we were being told the process of testing for these chemicals and metals I noticed that to test for them it was pretty complex and very interesting.
At the next station we tested the moistness of the dirt in three different places. First we pushed a tool into the ground. Next we pulled it up and collected the dirt. We stuck a tool that measured moisture in the hole and got the reading.
At the third station we were measuring the turbidity of the Mianus River. We measured the fast moving and slow moving water. After we made our hypothesis we went to get the water. Once we measured the water for turbidity, we came to the conclusion that the fast water was more turbid then the slow water. This was also our hypothesis because the fast moving water is picking up dirt and rocks, the slow moving water is not picking up dirt or rock because it is mostly settled.
