Mianus River Gorge-site 1

The Mianus River Gorge water test was very interesting. In the first station we had to test water turbidly. We took two river samples, fast flowing water, and still water. Some people thought that because the still water was still, the dirt particles would sink and it would be clear. Others thought that because the water was so fast flowing, the particles wouldn’t be carried with the water. We ended up concluding that the fast moving water is clearer than the still water because the water was moving so fast.
My second favorite station was testing the flow rate. We had three timers and five throwers. The throwers would throw a flotation devise upstream and once it went past a certain point, then the timers would start the clock and wait until it got to the finish line then stop. Then we repeated this for each thrower and recorded the information. Then we found the flow rate by distance/time.

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.

On the SoundWaters field trip, we tested for a number of different conditions in the water. At the first station, we tested for heavy metals, such as copper, iron or chlorine. It was surprisingly easy; all you had to do was drop some chemicals into the water and depending on the color the water changed to, you could find the level of any of those three different heavy metals.
At the second station, we tested the turbidity of the water, using a turbidity tube. The turbidity of the water is how clear or opaque the water is. To use the turbidity tube, you had to fill it up all the way to the top, and then let out water using a release at the bottom. You did this until you could see the black and white disc on the bottom. On the side of the tube, there was a scale, and depending on how high the water was on the scale, the water was, you knew how turbid the water is.
The second part of the second station was a test of flow rate. Using pre-measured dimensions of the river and the speed at which the river was flowing, we were able to find the flow rate of the water, or how much water was traveling past us each second. The flow rate was surprisingly high, because there had been a big storm the previous day.
At the third station, we tested for oxygen saturation. This station again required the use of various chemicals. It was a much more complicated process; however, it was still interesting to see how these types of tests are actually done.
Overall, the Soundwaters trip was enjoyable as well as interesting. It was nice to be able to learn in the outdoors instead of being inside all day. Even though the chemical names were difficult to remember and I did not always know what was happening, it was definitely one of the better field trips we have been on this year.

Mianus River Field Trip

The SoundWaters water testing field trip was located at Mianus River. We got to experience and learn about the quality of the river water in Stamford. I found it interesting to learn about the turbidity, salinity, acidity, and the water flow rate. At one station, a buoy was attached to a near by tree by a long rope. I got to throw the buoy out into the fast flowing water to measure the flow rate. In addition, I learned flowing water is less turbid than resting water. I observed that the water looked dirty, but in reality, it was clean. Consequently, the animal cycles can occur in a healthy way. I found it very interesting to learn about the river quality in the area I live in. I also observed a chart which stated that the water in 2008/2009 is much cleaner than the water in 1999. This shows that the water quality and the turbidity of the water has increased over the last several years.
Another activity we performed was testing the soil. We were split into three different groups to test the moisture level and particle size of the soil. My group was stationed at the point where the water was half way to the dirt. The other stations were near the water or very far away from the water. I took a core sample by pushing the core into the dirt. We lifted it up and a long tube of dirt was left. After, we observed the particle size of the dirt which was medium large and the moisture level which was also in the middle. I really enjoyed this great learning experience about the environment surrounding Stamford.

On Thursday April 1, my class went on a trip to the Mianus River Gorge to test the water quality. I had a great time going into the water, testing for unhealthy metals, and performing titrations. Also the Stamford Advocate came to take pictures, and learn a bit about what we were doing.
While on the trip, some students were designated to test the temperature of the water. The students were doing this, because Scofield was given an Hp grant. In return HP wanted a report on water, so the students chosen had to test it. They used HP graphing calculators and temperature probes to find the temperature.
I had a great time at the trip. I enjoyed testing the water, and conducting experiments. Also the day to test the water could not have been better. I loved it!

We went to the Mianus River to test the quality of the water. We tested things like what materials are in the water, the temperature, the flow of the water, and what was in the water. We conducted several experiments to find this, and we gathered a lot of information. Some of the information we found was surprising. For example, we found there was a large amount of fecal matter and other substances in the water.
During out trip, I was allowed to wear waders which enabled me to walk out in the water. This made it easier to get water samples, and it was also fun to stand in the water. The day we went the river was flowing fast, so I wasn’t able to walk out very far. Despite this, it was still and enjoyable experience.
Though it was a fun trip, much of the information that we gathered may not have been have been accurate to the average of the river. The storms and the rain from the past few weeks have thrown the river off. For example, because, of the run-off from all the rain, there was more dirt and outside substances in the river. Also, all the rain has caused the river to flow faster than it usually does. Even with this, it was probably one of the best field trips so far this year.

On Thursday April 1, 2010 was a fun experience, but it was still very educational. I learned a lot from this field trip about water. I learned about turbidity, how fast water the water was moving at the Mianus River, and how to find the pH level of soil and water. But, before we went anywhere, we had to take off our shoes and put on these big rubber boots that helped you walk in the mud, but made you feel like you were about to fall over any minute.
One of my favorite stations was the station where we had to find how clear, or turbid, the water was. We put the water in a big tube then drained it until we were able to see a black and white disk at the bottom. Then we also did something called titration. I thought titration was really cool because it made the water, which was originally a really dark brown color, clear again.
After we had lunch we went to station where we needed a sample of surface water and then water under the surface. To get the sample of water under the surface we used a tool that was a sideways tube with two cones on top of it at the end. This object was attached to a rope, so that you could put it into the water from a high place, we were on a bridge, and then are able to pull it up again. Once the object was in the water you dropped a weight from the rope, and if it fell in the right place, the cones would fall and close the tube on both ends with the sample of the water in it. Everyone got a chance to do this. The trip to Mianus River Gorge was a very educational and fun trip, and I can’t wait to visit it again.
