Introduction
Recently for my environmental class we took a field trip to the Wabashiki Wetlands. The Wabashiki Wetland is located in Terre Haute, Indiana. These Wetlands are there today due to the Terre Haute Tomorrow organization created in the early 2000’s. The land used to be used for many industries and mainly farmland. My group member Nigel and I were required to form a hypothesis about soil samples we took from the wetlands. Our hypothesis was that our soil samples from the wooded area of the wetlands would have fewer nutrients than the area where there used to be farmland. Through the remainder of the paper we will be talking about our methods of testing the soil, results of those tests, and our conclusion. The conclusion will discuss the final outcome of our hypothesis and an explanation of that outcome.
Methods
My group member Nigel and I had to collect samples from both areas that we had to test for our hypothesis. When we finally arrived at the Wabashiki Wetlands we went straight to the wooded area first. We then began to take samples of the soil using a small shovel. We had to test the pH levels of the sample as soon as we collected it. We did this by using the soil pH meter that was provided to us. Each of us had to take a sample so we could have more accurate data to support our hypothesis. While taking these samples we had to use an app on a phone that gave us the exact UTM coordinates of each sample. After we took samples from the wooded area we then proceeded to the old farmland area to conduct the same tests. We had to put these samples in small bags to take home and dry. By the beginning of next week our samples were dry enough to test for phosphorus, nitrogen, and phosphate levels. To test each soil sample ...

...ment. The reason why we were surprised at the results is because we assumed that there would be more nutrients in the farmlands, which was not the case. Also it was surprising that our data was noticeably different from one another because we collected soil in the same vicinity as each other. Based on the results we did have to adjust our hypothesis just because of the difference in nutrients. Our learning experience from this project was pretty interesting. Just learning the types of elements within the soil was very intriguing as well as informational. Being able to collect data outside of school made it a good experience as well, even though it was terrible weather. All in all, we learned there is more to an environment than what one would originally think.

The main problem was lead, with seven well samples showing up positive. The calcium and nitrates both had four samples showing up positive. Hydrocarbons had 3 samples showing a positive. Heavy metals have two positives,and bacteria had only 1 positive. Many men, women, and children are getting sick from horrible water pollution and some of the water pollutants cause cancer! So through all thirty of the tests we ran we got twenty one samples back that gave us a positive result. In conclusion the water in Hickory Hollow is justified, showing various
The data we found supported our original water hypothesis. My group and I believed that adding ammonium nitrate into our eco-column would ultimately damage the ecosystems. The increase in levels of minerals from the aquatic ecosystem also indicates that the entire column was being destroyed. Through this experiment, I have learned that too much nutrients and minerals within an ecosystem can be extremely harmful to the wildlife. Throughout this experiment the water in our eco column began to turn yellow because of a surplus of nitrogen and phosphorous in the eco-column. In some of the eco-columns of the other groups in the classroom, they had eutrophication in the early stages of their eco-column which resulted in the death of many of their
The purpose of this lab was to discover how diverse the parking lot at Bunker Hill High School could be, by finding out the Shannon Wiener biodiversity index of the parking lot. The parking lot was used because it does not have much immigration and emigration of the cars. Using an actual ecosystem in the wild would be hard to control, what is immigrating and emigrating out of the experiment. The experiment shows how diverse the cars were, and this can show how diverse an actual ecosystem was during that time of the experiment. This then tells that diversity does matters because if everyone had the same kind of car, then no one would be different. However, if the students, faculty, and guests had a variety of cars in the parking lot, which made the experiment more diverse in the parking lot or the community of cars.

Described as “ the jewel in the crown” of New Hampshire’s Lakes Region, Lake Winnipesaukee is the state’s largest standing body of water, nestled in the foothills of the White Mountains east of Laconia, in Belknap and Carroll counties. The lake is roughly 21 miles long and between 1 and 9 miles wide, with a surface area of approximately 72 square miles and a maximum depth of 212 feet. There are 258 islands in Lake Winnipesaukee, with a total shoreline of approximately 288 miles. This glacial, mountain lake was formed 1, 000, 000 million years ago resulting from glacial activities, that also consequently shaped the region’s beautiful landscape.
Mississippi has a variety of different soils .The three general soils are 1) the river flood plain, known as the Delta, 2) a loess region, or bands of soils formed in windblown material that adjoins the Delta, and 3) Coastal Plain. The Mississippi Delta is better for growing row crop, while the loess and Coastal Plain region are better for animal production and forestry. The loess and Coastal Plain regions are divided based on similar soils, geology, climate, water resources, and land use called Major Land Resource Areas. The Mississippi Delta’s soil comes from sediments left by flooding various rivers in the region, rather than being a typical Delta formed by the mouth of a river. In the Delta most of the land is farmed, with three-fourths of the cropland to the north. Controlling surface water and drainage are major soil management issues. In the Delta soils are naturally diverse because of their alluvial origin. Particle sizes within the sediment decrease as distance from the originating stream increase. Another factor in Delta soil formation us surface water movement over time, because soils that formed under standing water have different properties than soils formed under moving water. Soils with large amounts of clay particles have unique features. When the soil is dry, small round aggregates form at the surface that look like shotgun buckshot, which is where the popular name for Delta clay soils “buckshot” came from. Soils with large clay content have very slow water filtration rates; this has led to significant aquaculture and rice production in the region. When floodwaters receded in the Delta, strong winds blew some of the dry sediment left by flooded river to the adjacent uplands to form the loess areas. Because of eas...
John’s ability related to concentration, attention and exert mental control was assessed in the above average range and above approximately 87% of his peers (WMI=117; 95% confidence interval = 109-123). The Working Memory Index measures concentration and attention, short term memory functions, sequencing, facility with numbers and mental flexibility. John performed comparable on the two subtests contributing to the WMI, suggesting similar develop in both abilities. By calculating the difference between the highest and lowest subtest scaled scores for the WMI it was determined that these was no abnormal scatter (Scaled difference = 0).
Today while reading Ultimate Deer Food Plots by Ed Spinazzola, I was introduced to a food plot demonstration conducted by the Quality Deer Management Association (QDMA). They chose an area that showed poor soil conditions unsuitable for a food plot in Gladwin County, Michigan in 2001. There were a couple major reasons the soil was considered “poor”. First off, the soil was relatively light and dusty, which doesn’t offer the fertility of soil that is prefered when growing food plots. Next, there was a ½ inch to 1 ½ inches of duff (dead leaves, sticks, etc.) layered on the topsoil. Over a five year span, they worked to create a soil fit for growing. Each year, they sprayed the field with a herbicide to kill off plants that may compete with what
Pennsylvania has the most acid rain in the country, so it is not a surprise if the creek was polluted, but it’s not. It could be because of limestone rocks, or rocks that neutralize pollution in waters. Are next experiment was a eutrophication Test. A eutrophication is an enrichment of an ecosystem with chemical nutrients typically compounds containing nitrogen, phosphorus, or both. In this test we took samples of water into clear measurable tubes. There is 3 things we tested with water, Phosphate, nitrate, and dissolved oxygen. Phosphates and nitrates are examples of polyatomic ion. Phosphates and nitrates are found in fertilizers and some detergents. We tested for them and we didn’t get big results, so we know that waters aren’t polluted. There was a lot of dissolved oxygen, which is good, because that is what fish need to
At Goshen College, a small liberal arts college, Land Management is one of the courses required for Environmental Studies majors. The main book required for this class is Holistic Management by Allan Savory. Savory is a well-known ecologist and author. His books cover his theories on how to take care of land. His work is so well recognized that he is known as the founder of holistic management principles. The teacher of this Land Management, Bill Minter, draws most of his lectures from the information in this book. One might make the assumption that the information in a book approved for a class such as this would not contain controversial material. Both the teacher and the students in the class assumed just this, the material within the book had subsequent evidence to back up the theories. However, this is not the case. Allen Savory’s holistic management ideas on grazing and resting the land do not work in the basic ways that he claims they do. In fact, research has been done that disputes his theories. Therefore, it has been given a great deal of criticism by other scientist.
This paper introduces the environmental concerns of the loss of coastal wetlands. The paper will discuss the significance of wetlands and the devastation that is occurring because of human activity. Wetlands are an essential element of our environment both ecological and societal; conservation will be essential for the preservation of these precious ecosystems.
...ively place the suspect or perpetrator behind bars. Analyzing soil compounds can be measured by the levels of organic molecules including n-alkanes, fatty alcohols and fatty acids, which are all found in the waxy outer layer of plant matter (Geddes, 2008). It basically states that compounds can remain in the soil for thousands of years, which explains that each area being tested has its unique organic profile.
Some stories that aren't told in a history book teaches the best lesson. One such story is from 1940, when an unusual young man was buried in a custom-built ten-foot-long casket. The young man needed such a gigantic casket. Because he himself was a giant. He was just a shade under nine feet tall. And weighed almost five hundred pounds. Robert Wadlow, an American born in 1918, lived a tragic, pain-filled life. Weighing eight pounds at birth. Robert was a normal infant, but by the age of five, Robert stood over five feet tall his exceptional growth never stopped. He grew three inches every year until he died. Because a human's internal organs can't support an extremely large body. Robert was doomed to an early death, just before he died,
