Introduction Essays (1461 words) - Oxidizing Agents, Algae

Introduction In the pond water lab experiment, our group has chosen to test the effects of nitrates on a pond community. After a lot of research, we have found that nitrates in a pond community can increase growth rates of plants and some animals. The effects of nitrates include algal blooms, which is when too much food or nutrients are consumed by producers, (i.e. algae) causing them to grow and spread, so they consume all of the dissolved oxygen in the water. Most animals in water like many kinds of fish and some insects need certain levels of dissolved oxygen to live. When it is used up due to algal blooms, they die due to lack of oxygen. It also causes plants who need certain levels of dissolved oxygen to die, so it starves creatures that eat the plants. The safest range of nitrates in an environment is 3-10 PPM. Although too many nitrates can kill them, they still need some small amounts of nitrate. So if there is too little nitrates, then plant life is limited to the amount of food availabl e, giving room for a small, healthy community. The substance enters streams and ponds from fertilizers from farms, animal urine, septic tanks, landfills or agricultural activity. Nitrates are very common. My prediction for this experiment is that the nitrates will cause increased algae growth. Thus providing more food for the creatures in our sample. But since this is a short period of time, I expect the creatures to peak rather than die, because not enough time will pass for the algal bloom process to take place. Purpose Our group is trying to find the effects of increased amounts of nitrates in the pond community. Whether or not it is healthy for creature's living in the environment. In addition, what the results are or the effects of the pollutant on plant life and animal life. Hypothesis I expect for this experiment, that the plant life will thrive more and more with the different levels of nitrates entered into the pond samples. I expect for the animal life in the samples to thrive with the smaller amounts of nitrates added, and in the larger amounts animal life will die due to lack of water purity. Materials ? 4 20oz pop Bottles ? Scissors ? 4 pond water samples (same amounts) ? 4 eye droppers ? Masking tape ? Sodium Nitrates ? Scale ? Microscope (10x, 40x) ? Buckets ? Wet mount Supplies ? Water sifter ? Dissolved Oxygen Test Kit ? Nitrates Test Kit ? Fish net Procedure 1. First go to a pond and use the buckets to collect enough pond water for your experiment. Figure about enough to fill 4 20oz pop bottles. Use the water sifter and any other supplies to catch creatures from the water. 2. Next prepare your containers by taking the 4 20oz pop bottles, and cut the tops off of them, all in the same spot. Then tape all 4 containers together, taping the eye dropper holders on the outside corner of each bottle. Then write your names on the tape. 3. Then, carefully pour 400 ml of pond water into your containers. Make sure you equally measure out the same amount for each container. Then with the fish net, get a handful of creatures from the water and put them equally into you containers. Mark the water level on the container for each sample. 4. Then get your Dissolved oxygen test kit and you nitrates test kit and follow their instructions to test the levels in the water. Record your results, and use safety equipment if noted. 5. Now get a scale to measure your nitrates. The equation is divide 400 ml by x/1,000,000. X= amount of nitrates. 0-10 PPM (Excellent) 30 PPM (good) 60 PPM (fair) We added nothing to our #1 container, we added 2.1 grams of nitrates to #2, 3.2 to #3, and 4.8 to #4. 6. Add the nitrates to your water. Leave the bottles at room temperature. After every 3-4 days, collect data by creating a table. (# of container) 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 1.2.3.O. 7. Create a chart like this, and pick 3 creatures that a very common in your water sample. I picked... 1. Anacystis 2. Water Flea 3. Swimmer Then add whatever else you see in the O area that stands for Other. Each table is one days

Free Essays on Advertising And Ethics Free Essays on Advertising And Ethics Advertising and Ethics The purpose of advertising is to inform people of what is available for purchasing. This seems harmless, but too many advertisers set out to deceive consumers about their products. Unfortunately, they do a very good job with this and successfully deceive many people. Although consumers need to learn how to read advertisements correctly, the advertisers still have an obligation to inform about their products honestly Many advertisements give the impression that their product is better than it really is. People today tend to dismiss this as acceptable within the advertising realm; however, it’s harmful to consumers. This deception causes the consumers to spend money on things they would never purchase if ads hadn’t deceived them. This is unfair to the consumers. These consumers are working hard for money they are spending on things they will probably never use. I feel that it is completely unethical for advertising companies to condone this and simply write it off as â€Å"part of the job†. Some advertisements try to sell products that are obviously not what they claim to be. I’ve seen advertisements for soaps and lotions that burn away fat. Ads like these are amusing and make most of us wonder about the people who would actually fall for them and buy the product. While many ads like the ones just mentioned are easy to see through there are many that are more difficult to see as false. According to the Social Security Administration, recently many people were victimized by advertisers who used the words â€Å"Social Security† in their advertising to bring in consumers. Often the companies charged for services that were available for free through Social Security. Not only is this kind of advertising unethical, it is now illegal.

Theodore Roosevelt and Woodrow Wilson - Essay Example der with a discussion of primary sources and the means by which these primary sources represented the principles and actions of each of these former presidents. Firstly, with respect to an analysis of the primary documentation concerning Theodore Roosevelt, it is clear and apparent that even though this president believed in the American ideals of individual labor and capitalism, he was fundamentally opposed to the power that the â€Å"trusts† had created throughout the economy of America. Ultimately, Roosevelt and his fellow Progressives understood these trusts to be responsible for a reduction in the freedom and personal consumer choice that individual citizens were able to effect within the economy (The New Nationalism 1910). As such, Roosevelt came to be known as the â€Å"trust buster†; a term lovingly bestowed upon him by a press and a citizenry that was all to happy to see the power of these mega corporations shattered as they were split into smaller parts and/or forced to abide by new governmental standards of production/quality in the products they produced. The monopolizing power of these â€Å"trusts† was som ething the Bull Moose party was fundamentally opposed to and something that Theodore Roosevelt sought to reduce during the tenure of both of his terms as president. In terms of foreign policy, it was clear from an analysis of the primary documentation that Roosevelt was an internationalist; insomuch as he viewed the role of the United States as that of a world power that had a direct culpability to mediate foreign disturbances/disputes. As former Secretary of the Navy, this placed Theodore Roosevelt in a firm position to understand the dynamics and importance of a global sea power and the means by which the United States could continue to exhibit future strength by engaging with this determinant (The New Nationalism 1910). By means of contrast and comparison, Wilson was more eloquent, polished, and came across as more educated. Further, Wilson

gatdream Fitzgerald’s The Great Gatsby - Casting Doubt Upon the American Dream :: Great Gatsby Essays

Casting Doubt Upon the American Dream in The Great Gatsby   The Great Gatsby' is set in the Jazz Age of America, the 1920s which have come to be seen as a bubble of extravagance and affluence which burst with the Wall Street Crash in 1929. Fitzgerald wrote the book in 1925, and in it he explores the fundamental hollowness which characterized the Age as he saw it, and casts doubt upon the very core of American national identity - the American Dream. The American Dream is a concept elegantly simple and yet peculiarly hard to define. At the root of it is the sense that America was created entirely separate from the Old World; the settlers had escaped from the feudal, fractious and somewhat ossified nations of Europe and been presented with a chance to start anew - "a fresh green breast of the new world." From this blank slate, those first idealistic settlers had created a society where "all men are created equal" and everyone had the chance to do the best for themselves as they could. Let us examine the passage from the Declaration of Independence from which that quote is taken: "We hold these truths to be self-evident, that all men are created equal, that they are endowed with certain inalienable rights, and that among these are life, liberty and the pursuit of happiness." A fine and daring ideal in the 18th century, and at the heart of what America hoped that it stood for. 'The Great Gatsby' examines how this dream existed in the early 20th century and whether or not it had been accomplished. The American Dream permeated all of society, and so every one of the characters in the book is in some senses a reflection of the the world envisaged by Jefferson and Washington, and even before them by those first people fleeing to a new life in the New World. When we examine the characters in the book we can immediately see that they are not all born equal. Daisy and Tom, and to some extent Nick, are born into a rich, 'old money' environment which is symbolised in the novel by the established wealth of East Egg - a place of glittering "white palaces". Gatsby and the Wilsons are not 'old money', and despite Gatsby's wealth we get the impression throughout the book that through all his parties and social events he is trying to join that old clique, but never succeeding in elevating himself to the "distinguished secret society" of Tom and Daisy.

Psychoactive Drugs and Their Effects

Psychology Psychoactive Drugs and their Effects Medications that effect people psychologically are called psychoactive drugs. They are often helpful in treating depression, anxiety, insomnia, and other psychological complications. Psychoactive drugs don’t affect the underlying causes of these disorders, but they can provide symptomatic relief to allow people to live more normal lives. Anxiety can be defined as persistent nervousness, tension, or panic caused by stress or other psychological causes. Anti-anxiety drugs (also know as minor tranquilizers) are used to promote relaxation or reduce the physical symptoms of anxiety. Everyone feels depressed at times, but when it is prolonged and starts interfering with daily life, support, professional help, and psychoactive medications may be appropriate. Insomnia has many causes, including anxiety and depression. When the cause is known and can be treated, sleep patterns generally return to normal. When the insomnia is persistent, sleeping drugs may be appropriate. Drugs are classified according to their effects and actions on the mind and body. Example: Depressants, Hallucinogens, opiates and stimulants. Depressants (sometimes called downers) are a class of drugs that slow normal brain function. It acts on the central nervous system because of this effect on GABA activity that produces a drowsy or calming effect. GABA works to decrease brain activity. Depressants also carry high addictive potential. The withdrawal effects from long-term depressant use can be life- threatening and produce some of the worst consequences of any other drug classifications. Examples: alcohol, Valium, Xanax, Librium, and barbiturates. Hallucinogens (commonly referred to as Psychedelics) are drugs which cause altered perception and feeling. Hallucinogens have powerful mind –altering effects and can change how the brain perceives times, everyday reality, and the surrounding environment. They affect regions of the brain that are responsible for coordination, thought processes, hearing and sight. They can cause sensory or perceptual distortions in people to hear voices, see things, and feel sensations that do not exist. Hallucinogens change the way the brain works by changing the way nerve cells communicate with one another. Hallucinogens possess a moderate potential for addiction with very high potential for tolerance, moderate level of psychological dependence and low potential for physical dependence. Examples: LSD, PCP, MDMA,(Ecstasy), marijuana, mescaline, and psilocybin. Opiates (or narcotics) are powerful painkillers. They are made from opium, a white liquid in the poppy plant. Opiates produce a quick, intense feeling of pleasure followed by a sense of well being and calm. Long-term opiate use changes the way the brain works by changing the way nerve cells communicate with one another. If opiates are taken away from opiate-dependant brain cells, many of them will become overactive. As with many other drugs, opiates possess very addictive potential. Examples: heroin, morphine, codeine, Oxycontin. Stimulants (uppers) are a class of drugs that elevate mood, increase feelings of well-being, and increase energy and alertness. Stimulants can cause the heart to beat faster and will also cause blood pressure and breathing to evaluate. Repeated use of stimulants can result in paranoia and hostility. As with other drugs, stimulants possess very high addictive potential. Examples: cocaine, methamphetamine, amphetamine, MDMA (Ecstasy), nicotine and caffeine. Drug Abuse generally refers to drug taking that cause emotional or physical harm to one self or others example, operating machinery or driving a vehicle, while â€Å"under the influence† of alcohol. Addiction is a broad term referring to a condition in which a person feels compelled to use a specific drug. Drug addiction can be psychological, physical or both. Drug addiction is not the same as substance abuse or drug abuse. A Individual who abuse drugs are not necessarily drug dependent, people who are addicted to drugs, conversely are also called drug abusers.
