Herbert Run Experiment

313 Words2 Pages

Based on my observations I hypothesized that both Herbert Run and the Commons stream would have a high level of nitrate, conductivity, and turbidity. I hypothesized this because of traffic, liter, and the waste and pollution in both streams. For the Commons Stream, the Conductivity was 1086µS/cm. The turbidity was 0 FAU. Last, the Nitrate level for Commons was 0.08 ppm. For Herbert Run the conductivity level was 687µS/cm. The Turbidity level was 0 FAU and the Nitrate level was 0.02ppm. I accept my hypothesis and reject parts of my hypothesis. I reject that both streams have a high turbidity level. Both streams’ turbidity level is zero. I accept that both streams have a high nitrate and conductivity level. Herbert run and commons stream have high levels of nitrate and conductivity but commons stream has a higher conductivity and nitrate level. …show more content…

Herbert Run is prone to pollution as a possible result of the residential area and open to sewer lines. This results in litter being in the water, which has an adverse affect on the water. Commons stream is also cluttered with litter and students moving around the immediate areas that surround the stream. The conductivity graph shows a higher level of conductivity in the Commons Stream than Herbert Run. The conductivity level is twice as high in Commons Stream in comparison with Herbert Run, which means that the concentration of dissolved solids that are ionized in this stream is higher. The same is true for the nitrate levels. The location of Commons Stream could be the reason the nitrate level is higher. Commons Stream is near the UMBC parking lot. This in turn has both a heavy student and traffic population. Due to this the nitrates may be contaminated by the excess litter and trash found in the

The last test was called the Acidity test. The Acidity test gives us the alkalinity and acid of a stream. On the Ph scale it goes from 0 to 14. A stream with a great abundance of life will probably have a reading of 7 on the scale( which is near neutral). Here are the results from some of the tests.

The battle of Second Bull Run was fought August 28-30, 1862. The battle took place in prince William county Virginia (Manassas). John Pope was the major general for the Union side and later joined with George Brinton McClellan. The Major General on the confederate side was Robert E. Lee. There were 62,000 soldiers and 14,000 casualties for the Union and 50,000 soldiers and 8,000 casualties for the confederate.

Next, about 10 mL of both solutions, Red 40 and Blue 1, were added to a small beaker. The concentration of the stock solution were recorded, 52.1 ppm for Red 40 and 16.6 ppm for Blue 1. Then, using the volumetric pipette, 5 mL of each solution was transferred into a 10 mL volumetric flask, labelled either R1 or B1. Deionized water was added into the flask using a pipette until the solution level reached a line which indicated 10 mL. A cap for the flask was inserted and the flask was invented a few times to completely mix the solution. Then, the volumetric pipette was rinsed with fresh deionized water and

A stream with a great abundance of life would probably have a measurement of or near seven, which is near neutral, or the measurement may be a little higher. For a stream that is not as productive, the pH measurement may be higher or lower than seven. For the alkalinity test, the average was thirteen. An alkalinity test tells you if there are limestone, which neutralizes acid. The average amount of rocks that did neutralize acid was sixty five, while the average amount of rocks that didn’t neutralize acid was twenty nine.

We also did not find a high level of phosphates and nitrates in the water. My group also did a dissolved oxygen test on the water. The velocity of the surface water of the creek is at a normal rate. The Conodoguinet Creek appears to be healthy right now.

In the movie Cool Runnings written by Jon Turteltaub there are three runners and push kart driver who made a Jamaican bobsled team to go to Calgary, Canada to compete in the 1988 winter Olympics games. An important scene in the movie is when they are leaving Jamaica and arriving in Calgary Canada. Different types of techniques are used to show that they don't fit in in their new setting and are outcasts. Contrast of colour is used to show that Sanka, Deris, Junior and Yul don't belong in there new setting. Their clothes are completely the opposite of the general public.

The quantitative solubility of the unknown compound was determined to be 29/100ml. The known solubility of sodium sulfate is 28.11g/100mL water. Using the found solubility to compare to the known solubility of sodium sulfate. This solution created in the solubility test, the conductivity of the unknown compound was tested using an Ohmmeter to measure the resistance of the solution. Resistance is the measure of a substances ability to conduct

In 1879, when Pratt started to experiment with the Natives to which started teaching them English and Christianity as well as employment trades, not just the change of language or the practice of a religion without their consent, but they were actually being trade for employment to work as a young age, and not just that but Pratt stated or referred to them as objects not humans. Which is really inhumane by stating that he was actually “fixing them” like if there was something wrong with them and they needed fixing, treating them like things like you were to fix your car, or computer. “Not so surprisingly, the inmates overwhelmingly chose conversion and assimilation to longer imprisonment, so Pratt saw his experiment as a success and published

Society and government require people to be obedient towards authority, but is it always the best thing to do? During the aftermath of World War II many of the major leaders of the Nazi regime were put on trial for crimes against humanity (History.com). These trials were known as the Nuremburg war trials, were most of the convicted proclaimed that they were “just following orders” (McLeod 584). Being an accomplice to a crime is also against the law. In the Nuremburg trials, those accused were not breaking the law that their government had created, they were actually following it.

However, an overabundance of some nutrients, such as nitrogen and phosphorus, impairs water quality. “Agriculture is the largest source of pollution to the Chesapeake Bay and its rivers and streams.” quotes the Washington Post (Baker, 2015). About 50% of phosphorus and 40% of nitrogen dumped into the bay stems from agricultural runoff. According to the Chesapeake Bay Foundation, “Each year, roughly 300 million pounds of polluting nitrogen reaches the Chesapeake Bay—about six times the amount that reached the bay in the 1600s.”(cfb.org). The major sources of the excess nutrients comes from over fertilization of crops with animal manure seeping into waterways, and animals having direct access to waters where waste is carried into the watershed (Baker, 2015).

Farmers began to grow their crops in San Joaquin Valley for more than 100 years. Farms in the valley produce mostly vegetables, fruits, nuts, and dairy and they are the main manufacturers in international markets and major suppliers in the United States (Hanak & Arnold, 2017). Farmers are using polluted groundwater to grow their crops and harming the environment by drying rivers and causing people to get health problems. The reason that there are pesticides in nitrates in groundwater in San Joaquin Valley may be the fact that there is a long history of farming and irrigation and generally permeable sediments (Burow & Dubrowvsky, 2014). The first organization that noticed the growth of nitrates in groundwater is the Regional Aquifier System Analyses Program.
