Ph Levels Lab Report Essay - 871 Words

The relatively close pH levels of Tap Water, Spring Water, Flavored Water, and Seltzer Water. Introduction This experiment was performed to investigate the following hypothesis: The following four different types of drinking water (spring water, seltzer water, tap water, and flavored water) we test will relatively have the same pH level. Our group decided to test different types of drinking water to see if a pH level of tap water is comparable to other types of water. Many people believe that city water has many chemicals, causing us to form the expirement to see how close the different types of drinking water’s pH levels are. Materials and Methods For the first part of our exiperiment we used the Red Cabbage Indicator. Red†¦show more content†¦We then moved the electrode in one of the beakers of water we wanted to test. We measured the pH level, recorded it, then placed it back into the clean water it was orignally in. We repeated these steps for each of the different type of drinking water. The control treatment in our expirement was thr red cabbage indicator. The dependent variable is the pH of the water. The independent variable is the different types of drinking water ( tap water, spring water, seltzer water, and flavored water). The standard variables in the expirement are the clean test tubes, the clean pipettes, the Paraflim, the pH tester, and the pH levels pH 2, pH 4, pH 6, pH 7, pH 8, pH 10, and pH 12. Results Table 1 shows the standard of the standard of the expirement. It is used to compare the color of the red cabbage expirement to form an educated guess on the pH level of the different types of water. Table 2 shows the pH numbers we got from the red cabbage expirement and from the pH tester. This informations enables to compare the red cabbage and the pH tester numbers in order to prove the red cabbages accuaracy, and to prove our hypothesis that all of the pH numbers of the different types of drinking water are relatively close.

The Legalization of Gay Marriage Essay - 2475 Words

Ask any American what values founded this country and you will get very similar responses: Liberty, Freedom, or justice. These values are instilled in each American and come as naturally to us as the air we breath, or do they? Just as women fought for suffrage, and African Americans in the civil rights movement, homosexuals battle for the right to marry. This issue is affecting Americans on several levels. Politically, gay marriage is one of the hot issues that public officials are asked to take a position on. Legally, matters of jurisdiction have caused uncertainty on whether a couple of the same sex will be recognized should they decide to move.

New York, Rhode Island and Maryland ban same sex marriage, but recognize unions from other jurisdictions (Badgett 2). This uncertainty began with the Defense of marriage act or DOMA. In 1996, President Bill Clinton passed the Defense of Marriage Act, a federal law defining marriage as a legal union between one man and one woman. Section 2 of the act gave states the ability not to recognize same sex unions from other jurisdictions, while section 3 was even more controversial. It was the section that prohibited the federal government from recognizing any same sex union. This was the the first of many judicial acts that would cause the hazy view of same sex marriage in America. On February 23, 2011 President Barack Obama stated section 3 to be unconstitutional, taking a momentous step toward equality. However, the issue is far from resolved on the state level (Savage and Stolberg 3). When have such separate and oppos ing views been allowed between states?

Short Porters Rant Explanation free essay sample

Shakespeare’s Macbeth, Macbeth murders King Duncan and it drives him insane. The vicious murderer begins to have hallucinations and, by the time the murderers over, clearly is out of his mind. Shortly after the violent murder, a drunken porter is knocking at the castle door, which in his mind is the gate of Hell. The porter’s rant seemingly lightens the mood after such a violent, despair bringing seen. However, it actually provides audience with a deep, thought-provoking, understanding of Macbeth’s inner feelings. Upon first glance the porter’s rant is almost whimsical, and it is often said that Shakespeare included this just for a change of mood in the play. Actually, far the opposite is true, when the porter says â€Å"Faith, here’s an English tailor come hither [to Hell] for stealing out of a French hose. † (2. 3.  13-14), his words mean much more than regular drunken man’s babbling during a stupor. We will write a custom essay sample on Short Porters Rant Explanation or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page He’s referring to a tailor, who in the midst of providing a service to a man, steals right from the pocket of his clothes, similar to Macbeth who is providing a service to the king by being his thane, and his host, but kills him, and steals the crown from behind his back. When the porter then speaks about going to Hell, it’s almost an exact explanation of how Macbeth is feeling. Even before the murder, Macbeth is worried about the possible consequences, but after it was completed, he realized his previously imagined consequences would begin to come to life. Overall, the porter’s rant is far from meaningless. It’s not even whimsical; in fact it has a deep purpose to ensure the audience sees behind Macbeth’s face of stone, and come to understand better just what drove him to insanity.

Commentary on Judith Wrights Bora Ring free essay sample

A bora ring is a sacred site for indigenous Australians where initiation ceremonies for indigenous males were held. In her poem Bora Ring, Judith Wright mourns the loss in contemporary Australian society of the culture and traditions of indigenous Australians. She begins with descriptions of Aboriginal culture that has vanished as a result of European settlement. At the end of the poem, Wright recognizes the destruction wreaked upon indigenous Australians by their white brothers and shows remorse for these actions of the past. Through her use of diction, structural devices, and imagery, Wright expresses her sorrow at the disappearance of Aboriginal cultural heritage. In the first stanza of Bora Ring, Wright describes the loss of the songs, dances, stories and rituals of the Aboriginal Australians. Her use of the adjectives gone, secret, useless and lost emphasizes Wrights regret that this ancient culture has disappeared. The poet, through her use of the metaphor lost in an alien tale, highlights how Aboriginal culture has been replaced by European culture as a result of white settlement in Australia. We will write a custom essay sample on Commentary on Judith Wrights Bora Ring or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Her use of the word alien stresses her view that the white colonists do not belong in Australia; they are foreigners in the land. Wrights use of end-stopping and caesura, in combination with trimeter and pentameter, creates short emphatic phrases that portray her belief that this loss is irrevocable. The slow pace of the quatrain also serves to depict the poets remorse at the destruction of indigenous traditions. In the second stanza, Wright describes the remains of a bora ring. The Aborigines are no longer present: Only the grass stands up / to mark the dancing ring. Nature is the only reminder of the lost Aboriginal culture. The grass is personified as standing up; it encircles the dancing ring, almost as if it is guarding this sacred area. Wright also personifies the apple- gums. She suggests that their movements and sounds in the wind, posture and mime a past corroboree, / murmur a broken chant. Her choice of the verbs posture and mime emphasizes the way in which past generations of indigenous people gathered for corroboree, a sacred and ceremonial meeting involving music, song and dance. Through the use of personification Wright is thus able to convey the absence f the Aborigines in the bora ring. Wright further conveys the poignancy of the Aborigines disappearance in the third stanza. Structurally, the third and first stanzas parallel each other; both list aspects of indigenous Australian culture that no longer exist. In the first stanza, Wright highlights the loss of the song and the dance. Similarly, in the third stanza, she notes the absence of the hunter and the spear. Wright describes the spear as splintered underground, giving the reader an image of a weapon broken, smothered in the dirt, lying unseen. Thus, the poet stresses the xtinction of the Aboriginal tribal traditions. Wright also notes, through her metaphor of the painted bodies/a dream the world breathed sleeping and forgot that rituals such as corroboree are no longer practiced. Her use of the words dream, sleeping, and forgot emphasizes that these ancient rituals, so much a part of Aboriginal culture, have ceased to live on today. Wright then states that the nomad feet are still. Here, the word nomad refers to the itinerant lifestyle of the Aborigines, still now, since the Aboriginal way of life no longer has any value in
