How To Design a Science Fair Experiment

How To Design a Science Fair Experiment A good science fair experiment applies the scientific method to answer a question or test an effect. Follow these steps to design an experiment that follows the approved procedure for science fair projects. State an Objective Science fair projects start with a purpose or objective. Why are you studying this? What do you hope to learn? What makes this topic interesting? An objective is a brief statement of the goal of an experiment, which you can use to help narrow down choices for a hypothesis. Propose a Testable Hypothesis The hardest part of experimental design may be the first step, which is deciding what to test and proposing a hypothesis you can use to build an experiment. You could state the hypothesis as an if:  If plants are not given light, then they will not grow. You could state a null or no: There is no difference in the size of beans soaked in water compared with beans soaked in saltwater. The key to formulating a good science fair hypothesis is to make sure you have the ability to test it, record data, and draw a conclusion. Compare these two hypotheses and decide which you could test: Cupcakes sprinkled with colored sugar are better than plain frosted cupcakes. People  are more likely to choose cupcakes sprinkled with colored sugar than plain frosted cupcakes. Once you have an idea for an experiment, it often helps to write out several different versions of a hypothesis and select the one that works best for you. See  Hypothesis Examples Identify the Independent, Dependent, and Control Variable To draw a valid conclusion from your experiment, you ideally want to test the effect of changing one factor, while holding all other factors constant or unchanged. There are several possible variables in an experiment, but be sure to identify the big three: independent, dependent, and control variables. The independent variable is the one you manipulate or change to test its effect on the dependent variable. Controlled variables are other factors in your experiment you try to control or hold constant. For example, lets say your hypothesis is: Duration of daylight has no effect on how long a cat sleeps. Your independent variable is duration of daylight (how many hours of daylight the cat sees). The dependent variable is how long the cat sleeps per day. Controlled variables might include amount of exercise and cat food supplied to the cat, how often it is disturbed, whether or not other cats are present, the approximate age of cats that are tested, etc. Perform Enough Tests Consider an experiment with the hypothesis: If you toss a coin, there is an equal chance of it coming up heads or tails. That is a nice, testable hypothesis, but you cant draw any sort of valid conclusion from a single coin toss. Neither are you likely to get enough data from 2-3 coin tosses, or even 10. Its important to have a large enough sample size that your experiment isnt overly influenced by randomness. Sometimes this means you need to perform a test multiple times on a single subject or small set of subjects. In other cases, you may want to gather data from a large, representative sample of population. Gather the Right Data There are two main types of data: qualitative and quantitative data. Qualitative data describes a quality, such as red/green, more/less, yes/no. Quantitative data is recorded as a number. If you can, gather quantitative data because its much easier to analyze using mathematical tests. Tabulate or Graph the Results Once you have recorded your data, report it in a table and/or graph. This visual representation of the data makes it easier for you to see patterns or trends and makes your science fair project more appealing to other students, teachers, and judges. Test the Hypothesis Was the hypothesis accepted or rejected? Once you make this determination, ask yourself whether you met the objective of the experiment or whether further study is needed. Sometimes an experiment doesnt work out the way you expect. You may accept the experiment or decide to conduct a new experiment, based on what you learned. Draw a Conclusion Based on the experience you gained from the experiment and whether you accepted or rejected the hypothesis, you should be able to draw some conclusions about your subject. You should state these in your report.

A comparison of Still Lifes by Paul Cezanne and Francisco de Zurbran Essay

A comparison of Still Lifes by Paul Cezanne and Francisco de Zurbran - Essay Example Most impressionist paintings were done out of doors, many depicting scenes from everyday life, often with several figures and using bright, vibrant colors, and without any emphasis upon exact details. This is more unusually is an indoor scene and a still life, but there are still the bright colors and the lack of exact detail. It is exactly what it was meant to be – an impression of a kitchen scene. The items are very casually laid out, on what appears to be a kitchen table, almost with the appearance of being thrown down, and the background looks as if the artist has used it to clean his brushes, including as it does tiny amounts of many different colors, yet at the same time the viewer is able to distinguish exactly just what is being depicted as clearly as in the much more formal and realistic work earlier work by Zurbà ¡ran. Impressionism was not abstract art.

Discuss the political significance of shifting structural (economic, Research Paper

Discuss the political significance of shifting structural (economic, cultural, social, demographic) trends in Texas - Research Paper Example When examining the interactions that interconnect economic outcomes and decision making politically, we are studying structural trends and political economy. Therefore, this paper will discuss the political significance of shifting structural (economic, cultural, social, demographic) trend in Texas. Political economy The economy creates a significant context in understanding of Texas’ political culture. It can assist in the shaping of the political culture. The economy’s development can shape certain political stereotypes and perceptions-and the society’s various sectors. With much involvement of the government in the economy, economic actors from private sectors have every reason to get involved in political participation to become actors in politics (Gutierrez 217). Since the earlier settlement improved by oil production and land grants boosted by state law to the technology backed by the government in the past two decades, the government has been protecting an d promoting state economic interests. It has happened so with the positive participation of political representatives of the interests. This marriage of politics and business has been successful in the Texas government’s council. ... The stability of the marriage of politics and business stands on pragmatism of both the result and the cause of the state’s booming economic history. In Texas, the culture has created entrepreneurial politicians and giants of savvy entrepreneurs, the government has made and protected businesses and established industries with incentives, exemptions, state contracts and subsidies during both wicked and good economic times (Mayer 265).The resulting distortions and inefficiencies in the economy’ structure and negligence of public interests have hindered a diversified development of a modern economy. The in-come tax absence, the reluctance to set a side funds for the delivery of education and social services have distorted the state’s growth and development. With the agreement that the government’s business is to uplift business, it has been constant throughout the history of the state, the public services delivery like public health and education has been pre sent despite constitutional and legal mandate. It is no surprise that the link between the economy and government is political and occupied by the influence of well-financed and well-organized private interests. It is too unsurprising that state governments perpetuate efforts to deriver public services that might raise the state of Texas amongst other states. The interaction patterns between the policy makers and the economic interests in the â€Å"reduced services, low taxes â€Å"government dominance to both the broader body politics and government halls (Mayer 205). Business leaders, such as political leaders and several voters saw government income tax as beyond the reasonable realm. As a result, the state services provision remains low because the money to fund them is little.

Language structure and stage devices Essay Example for Free

Language structure and stage devices Essay A View from the Bridge is still relevant to a contemporary audience. Discuss this in relation to Millers use of language, structure and stage devices; showing how they are used dramatic effect.  Miller intended the play to be a modern version of a Greek tragedy and even though Miller set the play in a specific time and a specific place it still resembles that of a Greek tragedy. Miller has inputted a bit of him self into the play as the play is also based on his personal experiences. He confronts the audience with a situation which we know the outcome of, due to the timeless structure also used in Greek theatre. A View from the Bridge is and always will be relevant to todays events, society and happenings because of its Greek theatre influence, using very strong morals and timeless themes. Such as: Love, Betrayal, Hate, Jealousy, honor, and Identity, Which are maneuvered in and out of the play.  In the opening section of the play Miller sets the scene in Red Hook, the slum that faces the bay on the seaward side of Brooklyn Bridge, portraying to the audience the areas personality. Miller manages this to a fine art, as he visited and worked in Brooklyn as a ship-fitter and therefore knew the area and its surrounding people well. While in Brooklyn, he heard a story from a lawyer friend which was of a longshoreman who had snitched to the immigration bureau on two brothers who were living illegally in his home just to stop an engagement between one of them and his niece. This story is where he got most of his ideas from. Due to this he was able to describe through his use of language all the events so they have a realistic feel which could make the reader feel like it could have been set in todays society. The broken English used in the play, as a device, shows how uneducated the characters are but also how identifiable they are with people in society today. Words missing or words abbreviated, using an apostrophe, show this. They been pullin this since the Immigration Law was put in! They grab a green kid that dont know nothin', this broken speech is still direct and can be understood but still shows how the character feels. The language is used, like in Greek theatre, to also describe the settings with quite some precision. The devices Miller uses can also communicate to the audience what speech cannot. Furthermore, the language Miller uses combined with the stage devices he uses can communicate something completely different. For example: when Eddie is teaching Rodolfo to box and there is overlapping dialogue from Beatrice and Catherine which builds a lot of tension from I dont want to hit you, Eddie to No, no, he didnt hurt me., (Page 41) after the climax is reached when Eddie punches Rodolfo. The overlapping dialogue is meant to show confusion and a build up of tension to when Eddie hits Rodolfo. Although the overlapping speech builds up tension the audience knew that this would happen. Another example of language or even the lack of language and dialogue being used as a dramatic device is while Marco is lifting the chair (page 42). This is all done through language being used as a dramatic device. Here, is all that Marco says, the rest is communicated by his actions as he wants to communicate to Eddie what he cannot say aloud. He transforms what might appear like a glare of warning into a smile of triumph, and Eddies grin vanishes as he absorbs his look, this still has the intended impact that Marco wanted on Eddie without speech involved. This is very similar to what might have been used in Greek theatre, using acting and stage devices instead of language. Even today in every day life we do the same, using physical actions instead of words. Miller uses a lot of different techniques and devices to portray different ideas to the audience, to create meaning and make them understand. The stage devices Miller uses create meaning for the audience and reveal subtext, showing the inner feelings of the characters. For example: the phone booth glowing (Act 2, page 49), A phone booth begins to glow on the opposite side of the stage; a faint, lonely blue. Eddie stands up, jaws clenched, this reveals an amount of subtext to the audience showing them that Eddie is thinking of phoning the Immigration Bureau. The revealed subtext is also showing us that Eddie is feeling angered and is trying to hold back on something, causing more tension. Another example of language being used as a dramatic device is while Eddie is taking cheep shots at Rodolfo making out that he is homosexual with the dramatic devices before and after the comments, using a newspaper as his prop. (He has been unconsciously twisting the newspaper into a tight roll. They are all regarding him now; he senses he is exposing the issue and he is driven on.)I would be someplace else. I would be like in a dress store. (He has bent the rolled paper and it suddenly tears in two.

Piracy in the Media Essay -- Technology Music Entertainment Papers

Piracy in the Media In today’s technological age and consumer-driven economy, it is not a surprise that media piracy is a big business. It is estimated that in one year $12.4 billion worth of business is stolen from original manufacturers by media pirating. Piracy, the illegal copying or counterfeiting of copyrighted material, is a major problem for a vast range of industries (Ang, 2001). For example, just in the recorded music industry, â€Å"music pirates account for almost $300 million in lost record sales annually in the United States† (Gray Zone, 2002), and that is just in the U.S. More is lost in foreign markets. This not only affects the media manufacturers but also the consumers of the media. They become the victims of piracy that ultimately result in the driving up of prices of legitimate products. Distributors and retailers have been affected, too. Nearly forty percent of the retail market’s business has been stolen (Gray Zone, 2002). Before we begin discussing the piracy of music, television, and motion pictures, it is important to understand what exactly piracy and counterfeiting is and the laws that prohibit them. Counterfeits, referred to as pirated media, are defined as â€Å"reproduced copies that are identical to the legitimate articles including packaging, trademarks, and labeling† (Ang, 2001). To protect the creators of original material from being pirated, laws were formed known as copyright laws. A copyright is â€Å"a protection that covers published and published literary, scientific and artistic works, whatever the form of expression, provided such works are fixed in a tangible or material form† (Copyright, 2002), and with copyright protection, the creator of the original material has the â€Å"ex... ...ilable online: http://www.cable.mediapiracy/hawkins/cablemonthly/2000/7845332.html (accessed October 24, 2002).

Othello: A Man of Love and Passion Essay

In this age of epic, fantasy, scientific fictions and other creative stories, people are sometimes bound to forget the best things found in the past, the origin of everything that we are enjoying now. One of the best examples is the literary masterpieces that can be found way back a long time ago. William Shakespeare’s works are considered one of the best ideas of all time. His works might have been millenniums ago, but are still passed generations to generations due to its all time effect and appeal to all the people at any age. Some of his famous works are the forbidden love of Romeo and Julie, the power of Macbeth, and of course, the Othello. Othello is a story that revolves about how love can grow deadly and fierce. Indeed, love is a precious thing that is sometimes shadowed by jealousy and betrayal. Racism is also tackled on the story, the story has shown a how a simple skin color can widely affect one’s whole life. The story circulated on the life of the major character Othello, he is greatly described nowadays this way: A noble â€Å"Moor†, in the service of the Venetian State, Othello is introduced to us in the very first scene by the term â€Å"Moor†, when Iago complains that Othello has made Cassio his lieutenant and not him. We also learn from Iago that Othello has a relationship with the fair Desdemona. Respected by the Duke of Venice, who is the first to address him by Gulin 2 name (Othello in Act I, Scene III) and who sends for him when Cypress is threatened by Turkish forces, Othello is continuously described by his critics (Brabantio, Iago) as a â€Å"Moor† a reference to his dark skinned appearance and a reference to the race of Muslim peoples of north-western Africa to which Othello belongs. Othello to sum it all up is a simple African prince who lives together with his family on Europe. On his stay on the premises of Europe, he had become a Venetian military with the rank as general. Being a soldier, he got to help other people in need, thus, making him more a bit more knowledgeable than other people with regards to women. In the middle of the story, Othello and Desdemona, the daughter of Barbatio, will eventually be married with each other. Othello can best symbolize men who are undergoing discrimination in the society just because their skin color is darker than other people, a fact they would have never meant to be. But indeed, despite of all this betrayals that succumbs his whole personality and lies of the people around him, he still manage to show his wife Desdemona his unconditional and true over just like any other man unto his wife. The story Othello is now known to be the mother of all modern drama due to its mass appeal and timely story.
