Tips For Writing Papers For College

Tips For Writing Papers For CollegeAlthough students love to be able to write papers for college, getting ready for an exam is not the best time to do so. Students need to study and concentrate on what they have to do for a test or assignment, but they can't concentrate if they feel like they are being rushed. It is therefore vital that a student gets ahead of the game and understands how to properly organize their research papers for college, or else they will not be able to get them prepared in time.Students can organize their research papers for college in two ways. One way is to try and come up with papers in the last couple of weeks before their exams or assignments. A student who does this will find that he or she is generally overwhelmed by the task and can become disorganized.The second way to organize papers is to plan them in advance and go through them properly. This requires a student to keep a list of all the topics that he or she will need to cover, as well as all the r eferences and materials that he or she needs to have handy. Being organized has an important impact on student performance, so it is worth giving it some thought.Before the date of the test or assignment arrives, the student's class schedule may have changed and there may be a need to call his or her professor to inform him or her about any changes in the schedule. On this note, a student should always make sure that he or she follows his or her schedule. In the days leading up to the exam, a student should try to get all his or her work organized and read the assignment over many times to make sure that he or she understands it. Once the day of the exam arrives, a student should give extra attention to the papers and try to go over them very carefully.Papers should not be written quickly. For example, if there is an extra sentence that needs to be added in the middle of a paper, it is not a good idea to write it in the middle of the paper, but instead leave a little bit to write wh ile the student is still finishing up the other side of the paper. Doing this ensures that the paper flows smoothly.Students should avoid the practice of trying to solve the problem at hand without first going through it with the reference to see if it is correct. When a student looks at the assignment, he or she should be able to identify any errors and this allows the student to be able to solve the problem in question. With this knowledge, the student can then apply the knowledge and correct the mistakes.Papers should not be done too fast either. If the student is trying to get the papers done in time for an exam, then he or she should give the papers more time to complete. A paper that is given too much time to complete will inevitably be rushed, so a slow pace is better than no pace at all.Papers should also not be written so late that they take longer than necessary. Because of the pressures of having to write papers for a test or assignment, many students work themselves into a frenzy when preparing papers for college. These papers, however, should not be written during a time when the student has no spare time.

The Minimum Wage Policy During The United States - 1714 Words

News stories abound with demands from workers, organizations, and lawmakers to increase the federal minimum wage. Headlines throughout the country highlight recent minimum wage policy changes in major cities such as Los Angeles and Seattle. Last month, Governor Andrew Cuomo of New York announced an approved minimum wage increase to $15 an hour for all fast food workers in the state (McGeehan). Even the website for the White House has a separate page, â€Å"Raise the Wage,† advocating for Congress to increase the federal minimum wage to $10.10 an hour (Raise the Wage). The most commonly held beliefs supporting an increase in the federal minimum wage are the potential lifting of families above the poverty line and the reduced demand for governmental assistance promised by livable wages. Democratic legislators believe people who work hard in the United States should receive living wages that combat poverty. Emotions flare over the minimum wage debate due to its strong connection with poverty and governmental assistance. While the issue tugs at the heart, people must also consider the issue logically in order to avoid unforeseen consequences.

New England And The Chesapeake Region Before 1700 Essay Example For Students

New England And The Chesapeake Region Before 1700 Essay Although New England and the Chesapeake region were both settledlargely by the people of English origin, by 1700 the regions hadevolved into two distinct societies. The reasons for this distinctdevelopment were mostly based on the type on people from England whochose to settle in the two areas, and on the manner in which the areaswere settled. New England was a refuge for religious separatists leaving England,while people who immigrated to the Chesapeake region had no religiousmotives. As a result, New England formed a much more religious societythen the Chesapeake region. John Winthrop states that their goal was toform a city upon a hill, which represented a pure community, whereChristianity would be pursued in the most correct manner. Both thePilgrims and the Puritans were very religious people. In both cases,the local government was controlled by the same people who controlledthe church, and the bible was the basis for all laws and regulations. From the Article of Agreement, Springfield, Massachusetts it is clearthat religion was the basis for general laws. It uses the phrase beingby Gods providence engaged together to make a plantation, showing thateverything was done in Gods name. The Wage and Price Regulations inConnecticut is an example of common laws being justified by the bible. Also in this document the word community is emphasized, just asWinthrop emphasizes it saying: we must be knit together in this work asone man. The immigrants to New England formed very family andreligiously oriented communities. Looking at the emigrant lists ofpeople bound for New England it is easy to observe that most people camein large families, and large families support the community atmosphere. There were many children among the emigrants, and those children weretaught religion from their early childhood, and therefore grew up loyalto the church, and easily controllable by the same. Any deviants fromthe regime were silenced or persecuted before they could start anymovements that would be a threat to the authority of the church. Evenpeople like Ann Hutchinson and Roger Williams, who only slightlydeviated from the teaching of the Puritan church were expelled andforced to move to Rode Island. As a result of this tight religiouscontrol the society became very conservative in New England, and lifeevolved to be simple and not elaborate as in Virginia. In the Chesapeake region almost everything was exactly opposite of NewEngland. The immigrants were not idealists, but materialists, most ofwhom sought money. As John Smith mentions in his History of Virginia,many sought gold. As it can be observed from the ships list ofemigrants bound for Virginia, the immigrants were mostly young people,most of them men, and like it is stated in the same list they were allconformists of the Church of England, and unlike the Puritans, were notdiscriminated against back in England. As John Smith points out, manyattempted to go back when they found difficulties instead ofopportunities to get rich. Many others died of hunger when theCorporations that brought the settlers to America abandoned them, andthe difficulty of the situation is described in Document G. Thepopulation was very small and the dangers were huge. The pioneers hadto defend themselves against both, the Dutch and the Indians. As aresult, the people who survived the first few years were al l youngambitious and ruthless pioneers. These were not the type of people whowould be easily controlled. .u899e1bc6f81b6ad7d7f5919b57553458 , .u899e1bc6f81b6ad7d7f5919b57553458 .postImageUrl , .u899e1bc6f81b6ad7d7f5919b57553458 .centered-text-area { min-height: 80px; position: relative; } .u899e1bc6f81b6ad7d7f5919b57553458 , .u899e1bc6f81b6ad7d7f5919b57553458:hover , .u899e1bc6f81b6ad7d7f5919b57553458:visited , .u899e1bc6f81b6ad7d7f5919b57553458:active { border:0!important; } .u899e1bc6f81b6ad7d7f5919b57553458 .clearfix:after { content: ""; display: table; clear: both; } .u899e1bc6f81b6ad7d7f5919b57553458 { 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; } .u899e1bc6f81b6ad7d7f5919b57553458:active , .u899e1bc6f81b6ad7d7f5919b57553458:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u899e1bc6f81b6ad7d7f5919b57553458 .centered-text-area { width: 100%; position: relative ; } .u899e1bc6f81b6ad7d7f5919b57553458 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u899e1bc6f81b6ad7d7f5919b57553458 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u899e1bc6f81b6ad7d7f5919b57553458 .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; } .u899e1bc6f81b6ad7d7f5919b57553458:hover .ctaButton { background-color: #34495E!important; } .u899e1bc6f81b6ad7d7f5919b57553458 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u899e1bc6f81b6ad7d7f5919b57553458 .u899e1bc6f81b6ad7d7f5919b57553458-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u899e1bc6f81b6ad7d7f5919b57553458:after { content: ""; display: block; clear: both; } READ: Pro Athletes Salaries EssayThe independence of the pioneers of Virginia can be seen in BaconsManifesto.

The scientific method Essay Example

The scientific method Essay Laboratory Objectives After completing this lab topic, you should be able to: 1. Identify and characterize questions that can be answered through selecting investigation. 2. Define hypothesis and explain what characterizes a good selecting hypothesis. 3. Identify and describe the components of a scientific experiment. 4. Summarize and present results in tables and graphs. 5. Discuss results and critique experiments. 6. Design a scientific experiment. 7. Interpret and communicate results. Introduction Biology is the study of the phenomena of life, and biologists observe living systems ND organisms, ask questions, and propose explanations for those observations. Science assumes that biological systems are understandable and can be explained by fundamental rules or laws. Scientific Investigations share some common elements and procedures, which are referred to as the scientific method. Not all scientists follow these procedures in a strict fashion, but each of the elements is usually present. Science is a creative human endeavor that involves asking questions, making observations, developing explanatory hypotheses, and testing those hypotheses. Scientists closely scrutinize investigations in their field, and each scientist must present his or her work at scientific meetings or in professional publications, providing evidence from observations and experiments that supports the scientists explanations of biological phenomena. Read the following example and answer the questions that follow. Agricultural scientists were concerned about the effect of air pollution, sulfur dioxide in particular, on soybean production in fields adjacent to coal-powered power plants. Based on initial investigations, they proposed that sulfur dioxide in high concentrations would reduce reproduction in soybeans. They designed an experiment to test this hypothesis (Figure 1). In this experiment, 48 soybean plants, Just beginning to produce flowers, were delved Into two groups, treatment and no treatment.

One group of 6 treated plants was placed in a fumigation chamber and exposed to 0. 6 pimp (parts power plant. The experiment was repeated on the remaining three treated groups. The no-treatment plants were placed similarly in groups of 6 in a second fumigation hammer and simultaneously exposed to filtered air for 4 hours. Following the experiment, all plants were returned to the greenhouse. When the beans matured, the number of bean pods, the number of seeds per pod, and the weight of the pods were determined for each plant. Figure 1 . Experimental Design for soybean experiment. The experiment was repeated four times. Soybeans were fumigated for 4 hours. Determining the Variables Read the description of each category of variable; then identify the variable described in the preceding investigation. The variables in an experiment must be Leary defined and measurable. The investigator will identify and define dependent, independent, and controlled variables for a particular experiment. A) The Dependent Variable Within the experiment, one variable will be measured or counted or observed in response to the experimental conditions. This variable is the dependent variable. For the soybeans, several dependent variables are measured, all of which provide information about reproduction. What are the dependent variables? B) The Independent Variable The scientist will choose one variable, or experimental condition, to manipulate. This arable is considered the most important variable by which to test the investigators hypothesis and is called the independent variable. What was the independent variable? Can you suggest other variables that the investigator might have changed that would have had an effect on the dependent variables? He dependent variables, only one independent variable is usually chosen. Why is it important to have only one independent variable? Why is it acceptable to have more than one dependent variable? C) Controlled Variables Consider the variables that you identified as alternative independent variables. Although they are not part of the hypothesis being tested in this investigation, they would ha ve significant effects on the outcome of this experiment. These variables must, therefore, be kept constant during the course of the experiment. They are known as the controlled variables. The underlying assumption in experimental design is that the selected independent variable is the one affecting the dependent variable. This is only true if all other variables are controlled. What are the controlled variables in this experiment? What variables other than those you may have already listed can you now suggest? Choosing or Designing the Procedure The procedure is the stepwise method, or sequence of steps, to be performed for the experiment. It should be recorded in a laboratory notebook before initiating the experiment, and any exceptions or modifications should be noted during the experiment. The procedures may be designed from research published in scientific journals, through collaboration with colleagues in the lab or other institutions, or by means of ones own novel and creative ideas. The process of outlining the procedure includes determining control treatment(s), levels of treatments, and numbers of applications. The value set for the independent variable is called the level of treatment. For this experiment, the value was determined based on previous research and preliminary measurements of sulfur dioxide emissions. The scientists may select a range of concentrations from no sulfur dioxide to an extremely high concentration. The levels should be based on knowledge of the system and the biological significance of the treatment level. What was the level of treatment in the soybean experiment? B) Replication Scientific investigations are not valid if the conclusions drawn from them are based n one experiment with one or two individuals. Generally, the same procedure will be repeated several times (replication), providing consistent results. Notice that scientists do not expect exactly the same results inasmuch as individuals and their responses will vary. Results from replicated experiments are usually averaged and may be further analyzed using statistical tests. Describe replication in the soybean experiment. C) Control The experiment design includes a control in which the independent variable is held at an established level or is omitted. The control or control treatment serves as a encroach that allows the scientist to decide whether the predicted effect is really due to the independent variable. What was the control treatment in this experiment? What is the difference between the control and the controlled variables discussed previously? EXERCISE II: DESIGNING AN EXPERIMENT In this exercise, the entire class, working together, will practice investigating a question using what you have learned so far about the scientific process. Cardiovascular fitness can be determined by measuring a persons pulse rate and respiration rate before and after a given time of aerobic exercise. A person who is more fit may have a relatively slower pulse rate and a lower respiratory rate after exercise, and his or her pulse rate should return to normal more quickly than that of a person who is less fit. Your assignment is to investigate the effect of a well-defined, measurable, controllable independent variable on cardiovascular fitness. Specific questions can be asked about an independent variable related to the broad topic of cardiovascular fitness. For example, your question might be Does cigarette smoking have an effect on cardiovascular fitness? List the questions in the space revived. Choose the best question and propose a testable hypothesis. B) Hypothesis Record the hypothesis chosen by the class. The Experiment A test, called the step test, that is often used for assessing cardiovascular fitness (Sinusitis and Fine, 1987). Here are the basic elements of this test: 1. The subject steps up and down on a low platform, approximately 8 in. From the ground, for 3 minutes at a rate of 30 steps per minute. 2. The subjects pulse rate is measured before the test and immediately after the test. The subject should be sitting quietly when the pulse is counted. Use three fingers to find the pulse in the radial artery (the artery in the wrist, above the thumb). Count the number of beats per minute. (Count the beats for 30 seconds and multiply by 2. ) 3. Additionally, the pulse rate is measured at I-minute intervals after the test until the pulse rate returns to normal (recovery time). Count the pulse for 30 seconds, rest 30 seconds, count 30 seconds, and rest 30 seconds. Repeat this procedure until the pulse returns to normal. Record the number of minutes to return to the normal pulse rate. (Do not record the pulse rate. ) As a group, design an experiment and record the components below: Dependent variable(s): Controlled variables: Control: Level of treatment: Replication: Summarize the experimental designed by your class: Prediction Predict the results of the experiment based on your hypothesis (if/then). Following the procedures established by your investigative team, perform the experiment and record your results. Results Record total class results in a Table. Identify the treatment conditions at the top of the table. Presenting and Analyzing Results Once the data are collected, they must be organized and summarized so that the scientists can determine if the hypothesis has been supported or falsified. In this exercise, you will design tables and graphs; the latter are also called figures. Tables and figures have two primary functions. They are used (1) to help you analyze and interpret your results and (2) to enhance the clarity with which you present the work to a reader or viewer. Tables You have collected data from your experiment in the form of a list of numbers that may appear at first glance to have little meaning. Look at your data. How could you organize the data set to make it easier to interpret? You could average the data set or each treatment, but even averages can be rather uninformative. Could you use a summary table to convey the data (in this case, averages)? Table 2 is an example of a table using data averages of the number of seeds per pod and number of pods per plant as the dependent variables and exposure to sulfur dioxide as the independent variable. Note that the number of replicates and the units of measurement are provided in the table and table legend. Table 2. Effects of 4-Hour Exposure to 0. 6 pimp Sulfur Dioxide on Average Seed and Pod Production in Soybeans. Treatment Number Seeds per Pod Pods per Plant intro 243. 26 16 ASS 241. 96 13 Tables are used to present results that have a few too many data points. They are also useful for displaying several dependent variables. For example, average number of bean pods, average number of seeds per pod, and average weight of pods per plant for treated and untreated plants could all be presented in one table. All values of the same kind should read down the column, not across a row. Include only data that are important in presenting the results and for further discussion. Information and results that are not essential (for example: test-tube number, impel calculations, or data with no differences) should be omitted. The headings of each column should include units of measurement, if appropriate. Tables are numbered consecutively throughout a lab report or scientific paper. For example Table 4 would be the fourth table in your report. The title, which is located at the top of the table, should be clear and concise, with enough information to allow the table to be understandable apart from the text. Capitalize the first and important words in the title. Do not capitalize articles (a, an, the), short prepositions, and conjunctions. Refer to each table in the written text. Summarize the data and refer to the table; for example, The plants treated with sulfur dioxide produced an average of 1. 96 seeds per pod (Table 2). Do not write, See the results in Table 2. If you are using a database program, such as Excel, you should still sketch your table on paper before constructing it on the computer. Application 1. Using the data from your experiment, design a summary table to present the results for one of your dependent variables, pulse rate. Your table need not be the same size or design as the sample. In your table, provide units of the dependent arable (pulse rate). Tell the reader how many replications (if any) were used to calculate the averages. 2. Compose a title for your table. Refer to the guidelines in the previous section. Interpreting and Communicating Results The last component of a scientific investigation is to interpret the results and discuss their implications in light of the hypothesis and its supporting literature. The investigator studies the tables and graphs and determines if their hypothesis has been supported or falsified. If the hypothesis has been falsified, the investigator must suggest alternate hypotheses for testing. If the hypothesis has been supported, the investigator suggests additional experiments to strengthen the hypothesis, using the same or alternate methods. Scientists will thoroughly investigate a scientific question, testing hypotheses, collecting data, and analyzing results, until they are satisfied that they can explain the phenomenon of interest. The final phase off scientific investigation is the communication of the results to other scientists. Preliminary results may be presented within a laboratory research group and at scientific meetings where the findings can be discussed. Ultimately, the completed reject is presented in the form of a scientific paper that is reviewed by scientists within the field and published in a scientific Journal. The ideas, procedures, results, other scientists. Because of this, science is sometimes described as self-correcting, meaning that errors that may occur are usually discovered within the scientific community. Scientific communication, whether spoken or written, is essential to science. During this laboratory course, you often will be asked to present and interpret your results at the end of the laboratory period. Additionally, you will write components of a scientific paper for many lab topics.
