Science Project Example

Science project example is the advanced step of learning theoretical information. The application of theoretical knowledge has to be followed by the well-organized scientific project so that people can confirm the accuracy of the theory. Students might conduct science projects to master their understanding of information from books while scholars utilize them to confirm their discoveries. This paper also presents an example of the science project, emphasizes the importance of it, and explains all benefits of such approach. There are numerous examples of scientific projects that are ready for further investigation. While some of those projects are mastered by the brilliant scholars, some science projects can be performed at school. Students can invent their science project while the teacher has to implement additional proposals for science projects so that children will be able to apply their knowledge to practice. The science project is crucial to emphasize the importance of the ability to use the theoretical knowledge and simplify the learning process. As for the setup, students pair up, and the teacher gives each of those groups one ball. The objective of the project is to understand the concept of the free fall and to be able to apply that knowledge to the concepts learned in class previously. Extra credit can be granted to students who can do additional research on that subject and propose another project example for further investigation. The first student in each pair takes a ball and drops it from the window of the class. Another student from the pair stands outside and records the time of the free fall. The fun project continues in the class so that children can use the familiar formulas to calculate the acceleration of the free fall. After all, that number has to match the theoretical one. However, when children find that the results match those that are written in their textbooks, each of them will understand the origin of these formulas and how they relate to scientific research. Moreover, each student will be finally able to discover that acceleration is the same for objects with different masses in space because there is a vacuum up here and no gravity. The additional project could be the comparison between the time of the free fall between objects with different masses while the task would be to calculate the mass of those objects and confirm the formula of the gravity force that influences each of us. Furthermore, the difference in gravity at different areas of the globe could be explained by the difference in closeness to the Earth’s core. That project might not be done in the classroom so that student can conduct that project when they are out of the city or during their vacation for extra credit. To summarize the issue, science project is used to master the theoretical knowledge as well as provide the ability to apply that knowledge in practice. Science projects can be different, but the common thing for all of them is to conduct the practical use of the theoretical concept to confirm or refute it after all.

The Current Wealth Adequacy Of Older Americans Essay

While using financial ratios to measure wealth adequacey, Love, Smith, and McNair (2008) examined the current wealth adequacy of older U.S. households, those age 55 and older, using the 1998-2006 waves of the Health and Retirement Study (HRS). To establish a benchmark of wealth adequacy, poverty-line wealth was analyzed to establish a base-line level of wealth required to provide income over the projected remaining lifetimes of each household member. Due to the poverty line being an unaspiring goal to meet, 1.5 to 3 times poverty wealth was used as a relevant threshold. The results of the study indicated that the median older U.S. household is reasonably prepared for retirement, with a ratio of comprehensive net wealth to present value poverty-line wealth of about 3.9 in 2006. The study also determined that 18 percent of households possessed less wealth than what is necessary to generate 150 percent of poverty-line income over their expected future lifetimes. When comparing the leadi ng edge of the baby boomer generation in 2006 to households of the same age in 1998, Love et al. (2008) determined that the 2006 baby boomers held slightly less wealth than their elders. Moreover, single boomers showed higher incidence of inadequacy than the previoulsy measured generation.

Adventures Of Huck Finn And Superstitions Essay Example For Students

Adventures Of Huck Finn And Superstitions Essay Huckleberry Finn provides the narrative voice of Mark Twains novel, and his honest voice combined with his personal vulnerabilities reveal the different levels of the Grangerfords world. Huck is without a family: neither the drunken attention of Pap nor the pious ministrations of Widow Douglas were desirable allegiance. He stumbles upon the Grangerfords in darkness, lost from Jim and the raft. The family, after some initial cross-examination, welcomes, feeds and rooms Huck with an amiable boy his age. With the light of the next morning, Huck estimates it was a mighty nice family, and a mighty nice house, too110. This is the first of many compliments Huck bestows on the Grangerfords and their possessions. Huck is impressed by all of the Grangerfords belongings and liberally offers compliments. The books are piled on the table perfectly exact111, the table had a cover made from beautiful oilcloth111, and a book was filled with beautiful stuff and poetry111. He even appraises the chairs, noting they are nice split-bottom chairs, and perfectly sound, toonot bagged down in the middle and busted, like an old basket111. It is apparent Huck is more familar with busted chairs than sound ones, and he appreciates the distinction. Huck is also more familar with flawed families than loving, virtuous ones, and he is happy to sing the praises of the people who took him in. Col. Grangerford was a gentleman all over; and so was his family116. The Colonel was kind, well-mannered, quiet and far from frivolish. Everyone wanted to be around him, and he gave Huck confidence. Unlike the drunken Pap, the Colonel dressed well, was clean-shaven and his face had not a sign of red in it anywheres 116. Huck admired how the Colonel gently ruled his family with hints of a submerged temper. The same temper exists in one of his daughters: she had a look that would make you wilt in your tracks, like her father. She was beautiful117. Huck does not think negatively of the hints of iron in the people he is happy to care for and let care for him. He does not ask how three of the Colonelss sons died, or why the family brings guns to family picnics. He sees these as small facets of a family with a handsome lot of quality 118. He thinks no more about Jim or the raft, but knows he has found a new home, one where he doesnt have to go to school, is surrounded by interior and exterior beauty, and most importantly, where he feels safe. Huck liked that family, dead ones and all, and warnt going to let anything come between us118. Huck is a very personable narrator. He tells his story in plain language, whether describing the Grangerfords clock or his hunting expedition with Buck. It is through his precise, trusting eyes that the reader sees the world of the novel. Because Huck is so literal, and does not exaggerate experiences like Jim or see a grand, false version of reality like Tom Sawyer, the reader gains an understanding of the world Mark Twain created, the reader is able to catch Twains jokes and hear his skepticism. The Grangerfords furniture, much admired by Huck, is actually comicly tacky. You can almost hear Mark Twain laughing over the parrot-flanked clock and the curtains with cows and castles painted on them even as Huck oohs and ahhs. And Twain pokes fun at the young dead daughter Huck is so drawn to. Twain mocks Emmeline as an amateur writer: She warnt particular, she could write about anything you choose to give her to write about, just so it was sadful114. Yet Twain allows the images of Emmeline and the silly clock to deepen in meaning as the chapter progresses. Emmeline is realized as an early portent of the destruction of Hucks adopted family. The mantel clock was admired by Huck not only for its beauty, but because the Grangerfords properly valued beauty and wouldnt took any money for her111. .ufee530cd7c36f5c46873a9e03869cb55 , .ufee530cd7c36f5c46873a9e03869cb55 .postImageUrl , .ufee530cd7c36f5c46873a9e03869cb55 .centered-text-area { min-height: 80px; position: relative; } .ufee530cd7c36f5c46873a9e03869cb55 , .ufee530cd7c36f5c46873a9e03869cb55:hover , .ufee530cd7c36f5c46873a9e03869cb55:visited , .ufee530cd7c36f5c46873a9e03869cb55:active { border:0!important; } .ufee530cd7c36f5c46873a9e03869cb55 .clearfix:after { content: ""; display: table; clear: both; } .ufee530cd7c36f5c46873a9e03869cb55 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ufee530cd7c36f5c46873a9e03869cb55:active , .ufee530cd7c36f5c46873a9e03869cb55:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ufee530cd7c36f5c46873a9e03869cb55 .centered-text-area { width: 100%; position: relative ; } .ufee530cd7c36f5c46873a9e03869cb55 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ufee530cd7c36f5c46873a9e03869cb55 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ufee530cd7c36f5c46873a9e03869cb55 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ufee530cd7c36f5c46873a9e03869cb55:hover .ctaButton { background-color: #34495E!important; } .ufee530cd7c36f5c46873a9e03869cb55 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ufee530cd7c36f5c46873a9e03869cb55 .ufee530cd7c36f5c46873a9e03869cb55-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ufee530cd7c36f5c46873a9e03869cb55:after { content: ""; display: block; clear: both; } READ: Stylistic Analysis Of A Cup Of Tea EssayHuck admired the Grangerfords principles, and the stake they placed in good manners, delicious food, and attractive possessions. But Huck realizes in Chapter 18 that whereas the Grangerfords may value a hand-painted clock more than money, they put little value on human life. The third view of the Grangerfords world is provided by Buck Grangerford. He is the same age as Huck; he has grown up in a world of feuding, family picnics, and Sunday sermon that are appreciated but rarely followed. Buck, from when he meets Huck until he is brutally murdered, never questions the ways of his family. For the rest of the chapter, Buck provides a foil for Huck, showing the more mature Huck questioning and judging the world around him. In fact it seems Buck does not have the imagination to conceive of a different world. He is amazed Huck has never heard of a feud, and surprised by Hucks desire to hear the history and the rationale behind it. In Buck Grangerfords rambling answers we hear Mark Twains view of a southern feuding family, and after Buck finishes his answer, we watch Hucks reaction to the true nature of the Grangerfords. Buck details Twains opinion that a feud is not started or continued by thought. The reasons for the feud have been forgotten, and the Grangerfords do not hate, but in fact respect, their sworn enemies. They live their lives by tradition, and the fact that the feud is a tradition justifies its needless, pointless violence. From the dignified Colonel with a few buck-shot in him121 to Buck, who is eager for the glory to be gained from shooting a Shepherdson in the back, the Grangerfords unquestioningly believe in de-valuing human life because it is a civilized tradition. It is interesting that the only compliment Huck gives to a Grangerford after Buck shot at Harney Shepherdson was to Miss Sophia. He admitts that the young women who denied part in any family feud is powerful pretty122. But the rosy sheen that had spurred Huck to use the word beautiful six times previously in description of the Grangerfords has evaporated. He attends church with the family and notices all the Grangerfords keep their guns close by. Huck thinks it was pretty ornery preaching121, but the feuding patriarchy praises the good values listed by the Preacher. The hypocritical mixture of guns and sermons, holy talk and bloodthirstiness make it one of the roughest Sundays had run across yet121. He now questions the motives of everyone in the household, including Miss Sophia as she send him to the church on an errand. By this point the cynical, sarcastic Twain and the disillusioned Huck are of one mind. Huck walks among a group of hogs who have sought the coolness of the church and notes most folks dont go to church only when theyve got to; but a hog is different122. The narration of Hucks final day with the Grangerfords is prefaced by: I dont want to talk much about the next day124. For Hucks easy-going fluid dialogue to become stilted and censored, the reader knows the young boy has been hurt. A senseless fatal feud is not the only tragedy depicted through the events of that day, also shown is the heartbreak of a young boy who loses every vestige of the hopeful trust he put in a father, brothers and sisters. Huck is shocked to hear the fatherless, brotherless Buck complain he hadnt managed to kill his sisters lover on an earlier occaison. And then from his perch in the tree, Huck hears Bucks murderers singing out, Kill them, kill them! It made so sick most fell out of the tree127. He wishes he hadnt come ashore that night, to see such things127. The end of chapter nineteen, when Huck returns to the raft and Jim, almost exactly mirrors the end of chapter eighteen. Both chapter conclude with Huck enjoying a good meal with good company in a cool, comfortable place. First it is with the Grangerfords in the cool, high-ceilinged area in the middle of their double h ouse. Nothing could be better115, Huck thought. But only a few pages later the raft and Jim provide the same comforts. .u0dc5d256d67e2cc350203769f297ea9e , .u0dc5d256d67e2cc350203769f297ea9e .postImageUrl , .u0dc5d256d67e2cc350203769f297ea9e .centered-text-area { min-height: 80px; position: relative; } .u0dc5d256d67e2cc350203769f297ea9e , .u0dc5d256d67e2cc350203769f297ea9e:hover , .u0dc5d256d67e2cc350203769f297ea9e:visited , .u0dc5d256d67e2cc350203769f297ea9e:active { border:0!important; } .u0dc5d256d67e2cc350203769f297ea9e .clearfix:after { content: ""; display: table; clear: both; } .u0dc5d256d67e2cc350203769f297ea9e { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u0dc5d256d67e2cc350203769f297ea9e:active , .u0dc5d256d67e2cc350203769f297ea9e:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u0dc5d256d67e2cc350203769f297ea9e .centered-text-area { width: 100%; position: relative ; } .u0dc5d256d67e2cc350203769f297ea9e .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u0dc5d256d67e2cc350203769f297ea9e .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u0dc5d256d67e2cc350203769f297ea9e .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u0dc5d256d67e2cc350203769f297ea9e:hover .ctaButton { background-color: #34495E!important; } .u0dc5d256d67e2cc350203769f297ea9e .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u0dc5d256d67e2cc350203769f297ea9e .u0dc5d256d67e2cc350203769f297ea9e-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u0dc5d256d67e2cc350203769f297ea9e:after { content: ""; display: block; clear: both; } READ: Silas Marner - George Eliot EssayNothing had ever sounded so good to him as Jims voice, and Huck felt mighty free and easy and comfortable on raft128. . Huck happily slides away from the bloody scene with the unorthodox father figure of a runaway slave. Huck has realized he does not need a traditional family to make him feel safe and happy. He must develop and live by his own integrity, not the past decisions of a father or grandfather. This is clearly Mark Twains opinion also, and the reader, full of relief at Hucks escape, is aware that the author sent us all into the Grangerfords world to prove just that point.
