Harrison describes Eutrophic lakes as highly productive and turbid due to algae being present. Furthermore Harrison states that oligotrophic lakes have low productivity and are clear in the
On the trip with SWEEP the health of the Susquehanna River was studied. In order to do that, chemical test, biological tests, and physical observations were made. Chemical testing showed the more scientific side of water quality, such as the amount of nitrates, phosphates, the pH values, temperature, dissolved oxygen, and turbidity. Searching for macroinvertebrates was the biological testing. Certain macroinvertebrates and the quantity found determines how healthy the stream is.
This climate and the shield itself allows for a Boreal ecozone with podzolic soil. The dominant trees are now Pine, Birch and Maple. Blackstone Lakes water is soft in comparison with the Great Lakes hard water. For comparison, Lake Ontario has over 200 ppm of dissolved solids whereas Blackstone has a value, measured in July 1969 by The Ministry of Natural Resources as 23 ppm.
I hypothesized that the Conodoguinet Creek is polluted. Through my research I have found that the Conodoguinet Creek is not polluted. One reason it is not polluted is because most of the macroinvertebrates and crustaceans we found in the creek are pollution sensitive creatures. Another reason the creek is not polluted is the level of acidity and alkalinity is 7 which is a healthy number on the pH scale. If the acidity or alkalinity levels were high scientists would have to find a way to neutralize the acid and alkaline.
Two words…Water Wednesday!! There were many sounds of laughter in the air today in Garden 2! During Circle Time, we practiced writing our names and the letters “S” & “T”. For Show & Share, friends had wonderful summer collages of themselves. We were so proud!
phosphates and nitrates ) - which is when fertilizers < such as those on farms > can seep through the soil or even run down the soil - called runoff - into the creek causing the water to have more nutrients than it should. ) Depending on how much pollution there is depends on how much algae there is ( the more eutrophication -there is the more nutrients in the water- results in how much algae there will be.) We were also testing on the pH scale ( which measures the acidity or alkalinity of water ) goes from 0 - 14 where 6 - 0 is higher acidity and 8 - 14 is higher alkalinity ( alkalinity is what neutralizes/destroys acid. ) 7 on the pH scale is neutral and that is the ideal water for the ecosystem. The pollution that we were testing for is where the acid came from to begin with.
In the 1980s, the world experienced many social changes and throughout the United States, social and foreign issues occupied the Post-Vietnam community. In Thomas Boyle’s “Greasy Lake,” he focuses his writing on the many societal issues that occupy the era in history and uses teenage experience to capture the horrors of the Vietnam war. With a New Historicist and Feminist lens, Boyle highlights the social issues of the 1980s by revealing the attitude towards the female characters and the role of the main protagonist in regard to social interactions after the Vietnam war. The 1980s marked the beginning of a new era in American history for the United States had pulled out of the Vietnam War; furthermore, Boyle takes advantage of this time period
Water is extremely important when it comes to shaping Michigan. It has been shaped physically in the forms of glaciers, rivers, and lakes. It has been shaped both physically and socially by the migration of people. Michigan is surrounded by about 20% of the world’s fresh water, known as the Great Lakes. These lakes are maintained by many things including the water cycle, wetlands, wildlife, sand dunes, and many other natural resources.
Lake Superior Lake Superior is one of breathtaking beauty with such clear water that the average underwater visibility is 27 feet. It is not just the biggest of the Great Lakes, it is the largest body of fresh water on this planet. The lake is 160 miles wide and 350 miles long with a surface area of 31,699 square miles and a water volume of 2,900 cubic miles. The deepest part of the lake is 1,300 feet. During most winters, it is covered by ice on 40 to 95 percent of its surface, but it rarely freezes completely because of its depth.
Bill McEwen does not only use ethos and logos to express and reach out to the reader, but he also uses pathos. With pathos, the author can get into the reader’s mind and make them feel a certain way with his use of words. An example of pathos in the article can be easily shown when McEwen says” The reality is, our federal and state government will spend hundreds of millions-if not billions- of dollars in coming years on a program that will yield a salmon exhibit instead of a substantial fishery”(McEwen 9). McEwen’s use of pathos can be clearly identified in this phrase by looking at the way he states what he is saying. Here, McEwen does not use any facts or famous experts, but he does say this in such a way that the gets the reader really thinking
Film #1 - “The People of the Kattawapiskak River” Introduction In the documentary “The people of the Kattawapiskak River”, the housing crisis and lack of assistance promised in Northern Ontario is represented. The Documentary closely follows the chief of the Attawapiskat tribe and portrays the difficult living conditions endured by local residents. These problematic conditions include the lack of clean water, electricity and basic housing especially during the intolerable cold Canadian winter. Moreover, when a colony around the world is suffering it is our duty as human beings to help them through their difficult times.
One sweltering, stifling hot afternoon in July, I had the immense privilege of participating in Share-the-Lake Day as one of my first volunteer events being a member of the National Honor Society. Share-the-Lake Day is an annual sponsored event that offers nursing home inhabitants an outdoor lunch and a day out on the lake. I have always enjoyed spending time with elderly people because I find their wisdom and experience to be incredibly intriguing and fascinating. I loved listening to their stories of which they were extremely content to share. To see their eyes dance as they recounted a fond memory from their youth or witness their excitement when I mentioned various thoughts of mine that reminded them of a favorite family member or close
People learn from the mistakes they make; Sometimes it takes many mistakes for someone to learn a lesson. In T. Coraghessan Boyle’s “Greasy Lake”, “bad” boys take on many conflicts which ultimately lead to them to realize they are not who they believe they are. The boys would always go on late night car rides while drinking, in search of something “bad” to do. The three boys eventually found a friend’s car, or so they thought. Thinking it would be funny, they decided to mess with the wrong person.
Australia is a double-edged sword global citizen that plays a significant role and an influential part of the United Association, which tries to create a safer, fairer and more sustainable world. Australia's position in the UN is to maintain international peace and security, moreover to strengthen friendly relations among nations, and to achieve global cooperations. ' Australia values the United Nations as an essential forum through which impacts world affairs, promote a firm international framework also to pursue trading, economic interests and promote Australian values.' This is a quote from UN.org that describe Australia's position perfectly.
The Biotope Aquarium Explained In a biotope aquarium, the aquarist attempt to simulate a natural habitat, assembling fish species, plants, water chemistry and decorations found in that specific ecosystem. A “true” biotope should be a mirror of a natural habitat. There are many good reasons for setting up an aquarium that simulates a natural habitat. Those of us who have done everything, bred everything and kept most fish might simply want a new challenge.
