Observation Of Water In Sycamore Creek

all treatments contain the same type of soil, are planted in the same size of pan, are exposed to the same amount of sunlight, and are maintained at the same temperature throughout the course of the experiment. ON THE TEST there will be a number of related questions about this section not just the question shown below.

Each watershed varies depending on location. The Salem Creek watershed naturally consists of rocks, vegetation, water, clay and loam soils, slopes, and juvenile aquatic life. Conversely, there is naturally some stream bank and soil erosion. As for human features, the watershed consists of drainage pipes, sewage pipes, bridges, mounds of cement, and pollution sources. Most of the human features are generally in the highly urbanized areas of the watershed, which consists of northwestern portion of Winston-Salem, NC. There were also impervious surfaces bordering both sides of the watershed. On the stretch parallel to Old Salem Road, there was Old Salem Road on one side of the watershed, and housing and other buildings on the other. With the portion that is appears near South Main Street, there is a multiuse development and major road bordering it. There is also cement on the furthest side of the watershed and a sidewalk on the other that border the wide portion of the watershed that is located in the Salem Creek Greenway.

For the second part of the experiment I cut the cheesecloth into four pieces and folded them so that it was four layers thick. I placed one piece of cheesecloth into the funnel and measured 60mL of soil using the 100mL to help measure the soil and poured that into the funnel. Taking beaker number one I poured the contents into the funnel and let that filter into beaker number five. I used the same technique as above and I repeated the same thing to beakers number two through four and poured them into beakers number six through eight. Once this was done I observed beakers five through eight and wrote down my observations in Table 1.

Complete this week’s lab by filling in your responses to the questions from Geoscience Laboratory. Select answers are provided for you in red font to assist you with your lab work. Although you are only required to respond to the questions in this worksheet, you are encouraged to answer others from the text on your own.

I will measure the soil PH in 5 different places to get an accurate and reliable results.

The Silver Bow Creek watershed in southwest Montana encompasses approximately 474 square miles and forms a portion of the headwaters of the Clark Fork River and ultimately, the Columbia River (Montana Natural Resource Damage Program, 2009). The site covers about 26 miles of stream and stream side habitat. Silver Bow Creek was used as a conduit for mining, smelting, industrial and municipal wastes for more than a hundred years (Weitz, Luxenberg). Rather large amounts of mine tailings deposits are found along the creek. These deposits contain elevated levels of metals and have been dispersed over the entire flood plain (Weitz, Luxenberg).

The highest elevation of the site is 200m above sea level and Pit 2 is the closest to this high point(Figure 1). As elevation decreases, particles are transported from higher elevation to the lower elevation due to gravitation and water flow process. In addition, the appearance of the Barber Creek indicates the process of fluvial(Figure 1). During raining seasons, the creek will be over flooded, alluvium process will occur, where light particles are suspended in the water and heavy particles are deposited along the creek bed.

The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water. Drops were carefully counted and emptied into the empty plastic 25 mL graduated cylinder until the water level reached 1 mL. The number of drops in 1 mL was recorded into data table 3. The thin-stemmed pipet had a total volume of 4 mL and that was also recorded into data table 3.

Qualitative Observations: Comparatively Cedar Creek had much more trash than James A. Reed, so because there was more trash at Cedar Creek we can assume that is why the water quality was poorer than James A. Reed water quality. Arriving at the site we first went right towards where most of the other groups were heading. The first site we tested were clear shallow riffles. We did rock kicking and and and did little to rub the rocks. It was surprising how much black fly larvae we found compared to the other organisms. The second was harder to find because most over the overhanging sites because lots of the areas were much deeper so we were not able to test the areas, but we eventually found an area that we were able to get a sample from. The

1. Make a wet mount (Ex 12) of a small sample of the alfalfa water. Examine at 1000X total magnification using high contrast. This will illustrate how many organisms, both motile and non-motile, are present in the sample.

Analysis of representative soil samples will also be undertaken to characterise different soil material, for example, pH, particle size, organic matter, potential contaminants and so on.

Over the course of the school year, my science class visited the watershed near Langston Hughes to observe organisms through the different seasons. The watershed ecosystem was comprised of trees, animals, a streams, and other plants. We took notes and drew illustrations of a tree we chose at the beginning of the year, as well as take note of the surrounding area and apply what we were currently learning to our observations. Through those experiences, I have learned much more about a watershed ecosystem and its organisms interact and how my tree plays a role. But I have also noticed through the watershed walks that there were man made landmarks in the watershed, such as the pavement and the tunnel. That led me to wonder; is it necessary to conserve

1. A representative sample was chosen by quartering (according to BS 812: Part 102: 1984) or by use of a sample splitter (Fig. 2C1-3). The sample to be tested should be the approximate weight desired when dry. For this experiment, about 3 kilograms of coarse aggregate was weighed.

Graph 1 shows the failure peak points of the samples. It is important to note that the specimens tested at 100 kN/m2 and 200 kN/m2 reacted similarly, showing similarly shaped graphs to their peak and then descending gradually till they tail off. However, the 3rd specimen showed a steep ascend to it’s failure point and then descends steeply afterward as compared to the first two samples. The constant changes within the first ascending parts of the graph for all samples may be indication of the soil samples settling to the pressure or filling in the
