How Philosophy Has Changed Our Existence - 1932 Words
Philosophy has strived to understand our purpose and reason for being alive. People have long searched for the solutions to the many questions about our existence. Through this search people have formed their own ideas about the possible answers. Until a year ago I had thought that I already knew my position on life and the meaning of our existence. I believed I had all the answers and that I was correct in them. I was an atheist who believed in no god, creator, or an afterlife. To me life could be considered meaningless to a degree. The thought that one lives, dies, and that nothing more would happen was a hard belief to believe in. Despite the sad ending I firmly believed in it. During last years Christmas break however, that all changed. This newfound belief brought about happiness and many possible solutions to our existence. Last year I returned home after my first semester of college. During that semester I had matured greatly. My brother however was failing in school due to some drug abuse. I had taken the lead on getting him back on track. My family and especially my father had noticed a considerable change in me. After several hours of meeting together to discuss the problem my father looks at me and starts to cry out of happiness. I have never seen my father cry before in my life so it was very shocking. The next day my mother hands me a book and tells me that it is a story about my first five years of life. The book begins with my fatherââ¬â¢s brother Barry.

Women s Rights During The 1848 Seneca Falls Declaration...
The women of America have struggled to gain the same equality as men. The 1848 Seneca Falls Declaration and the Triangle Shirtwaist Factory fire were two documents showing the mistreatment and the unfairness of women in the work place and America as a whole. Some people did not believe women had the same rights as men, but women thought otherwise and wanted their voice heard. The aspects of equality in the American Dream were unavailable to women because women were not given the same rights as men. Similar to the Declaration of Independence which showed the unfair laws Britain placed upon the colonies, the Seneca Falls Declaration explained the rights not given to women by men. One of the grievances in the Seneca Falls Declaration stated, ââ¬Å"He has never permitted her to exercise her inalienable right to the elective franchise. He has compelled her to submit to laws, in the formation of which she had no voiceâ⬠(Stanton, Anthony 57). In other words, women had to obey the law s just like men did, but women did not have the right to vote. Women had no voice in which laws were passed but they understood that by being citizens of America they should have a say in the government. The Seneca Falls Declaration clearly stated, ââ¬Å"Having deprived her of this first right of a citizen, the elective franchise, there by leaving her without representation in the halls of legislation, he has oppressed her on all sidesâ⬠(57).

The Effects of Advertising - 2126 Words
The Effects of Advertising Advertising is considered a paid communication through a non-personal medium in which the sponsor is identified and the message is controlled. Variations include publicity, public relations, product placement, sponsorship, time shifted advertising, underwriting, and sales promotion. Every major medium is used to deliver these messages such as the television, radio, movies, magazines, newspapers, the internet, and billboards. Advertisements can also be seen on the seats of grocery carts, on the walls of an airport walkway, and the sides of buses, or heard in telephone hold messages or in-store PA systems Ãâ" nearly anywhere a visual or audible communication can be placed.

For instance, a 1987 survey conducted by the city of St. Louis found twice as many billboards in black neighborhoods as white. Almost 60% of the billboards in the black neighborhoods advertised cigarettes and alcoholic beverages. In another study of seventy-three billboards along nineteen blocks in a black neighborhood in Philadelphia, sixty advertised cigarettes or alcohol. In a 1989 survey by the Abel Foundation, 70% of the 2,015 billboards documented in the city of Baltimore advertised alcohol or tobacco products. Three-fourths of the billboards were in predominately poor African-American neighborhoods. In fact, the Center for Disease Control estimates that billboards advertising tobacco products are placed in African-American communities four to five times more often than in white communities. Furthermore, the advertisements are usually for menthol cigarettes, which are more popular with African- Americans and which have additional significant medical effects. (Randall, 2005) According to an article found in a Washington DC newspaper, minorities, particularly blacks, have been disproportionately targeted by the tobacco industry giants. The internal company records of R.J.

Definition and Examples of Pet Phrases in English
Pet phrase is an informal term for an expression frequently used by an individual in speech and/or writing. A pet phrase may be widely known (a clichà ©, for instance) or peculiar to the individual who employs it. Examples and Observations [In the 1955 movie Kiss Me Deadly] Va-va-voom! Pretty pow! is Nick the Greeks running-gag description of Hammers sports car engines, connoting both their sexual potency and explosive potential (Nick removes two bombs from the Corvette).(Vincent Brook, Land of Smoke and Mirrors: A Cultural History of Los Angeles. Rutgers University Press, 2013)Shed work as an insurance saleswoman, save up a tidy sum of money, enjoy her days off, gazing at herself in the mirror of some brand-name stores. Who I really am . . . Who I really am . . . would become her pet phrase, but after working for three years, shed finally realize that the image shed created of herself wasnt who she really was at all.(Shuichi Yoshida, Villain, trans. by Philip Gabriel. Pantheon, 2010)Whenever his conscience pricked him too keenly he would endeavor to hearten himself with his pet phrase, All in a lifetime. Thinking over things quite alone in his easy-chair, he would sometimes rise up with these words on his lips, and s mile sheepishly as he did so. Conscience was not by any means dead in him.(Theodore Dreiser, Jennie Gerhardt, 1911)Desegregation With All Deliberate SpeedLawyers promptly set to work trying to pin down the origin and significance of with all deliberate speed. And as Supreme Court materials from the Brown [v. Board of Education] years gradually become available, scholars have made a cottage industry of working out how and why the phrase made it into the Brown order. Although the Court in Brown spoke only through its Chief Justice, Earl Warren, this was actually a pet phrase of Associate Justice Felix Frankfurter, who had used the expression deliberate speed in five different opinions since joining the Court in 1939.(James E. Clapp and Elizabeth G. Thornburg, Lawtalk. Yale University Press, 2011)Game Changer and Thinking Outside the BoxWe have to look creatively, said stadium board Chairman Don Snyder, UNLVââ¬â¢s acting president. We canââ¬â¢t get in the way of the (convention c enter project). . . . Thereââ¬â¢s a tremendous scramble for limited resources.No longer was Snyder rolling out his pet phrase of game changer to describe the stadium wish. Now, heââ¬â¢s using another phraseââ¬âthinking outside the boxââ¬âto describe what it will take to pay for the proposed venue.(Alan Snel, UNLV Stadium Panel Members Begin Puzzling Out Funding Solutions. Las Vegas Review-Journal, February 27, 2014)Frank Sinatras Ring-a-Ding-Ding![Sammy Cahn] and the composer Jimmy Van Heusen were commissioned by [Frank] Sinatra to write a song using Sinatras catchphrase for his first Reprise album, which was called, not surprisingly, Ring-a-Ding-Ding! The phraseââ¬âlike Shakespeares Hey nonny nonnyââ¬âthumbed its nose at meanings and sincerity.(John Lahr, Sinatras Song. Show and Tell: New Yorker Profiles. University of California Press, 2000)Using Pet Phrases in WritingRepeat a distinctive thought or phrase of dialogue in the story. This connects an earlier pa rt of the story to a later one without having to rely on an overt transitional device. Television shows frequently overuse this technique, giving one character a pet phrase that he repeats ad nauseam. One way to vary the device is to give it a different meaning each time its used. On Seinfeld, all the principal characters would use the same phrase, often with a different meaning, all in the same scene, creating a device all its own.(James V. Smith, Jr., The Writers Little Helper: Everything You Need to Know to Write Better and Get Published. Writers Digest Books, 2012)Pet Expressions in 19th-Century EnglandNobody who has busied himself with watching the peculiarities of contemporary speech can have failed to notice the prevalence of pet expressions. . . . The young man of the day, in particular, has a slow and sluggish mind, and can seldom be troubled to give a careful specification of the particular person or thing which forms the topic of his conversation. He finds it answers bett er for his purpose to choose some simple generic term which he can use when his thoughts fail him. What the trapeze is to the acrobat, his pet expression is to the modern young man. It serves as a rest to steady himself on and to sustain him until he takes his next awkward flight. Many a fall would that young man have, many an awkward hiatus or wrongly-chosen expression would there be in his discourse was not his pet phrase always near him to be rested on half-way whenever the exigencies of his narrative become too much for his powers of speech.The conversation of the young lady of the period is principally remarkable for its adjectives. Unlike the young man, she has rarely any pet substantive whereby to express most things that come under her notice; it may be that she refrains to use her brothers phrases for fear of being considered slangy. But she rejoices in a curious collection of qualifying adjectives, by the aid of which she manages to make her meaning known. Anything that pl eases her, from a bracelet to a sunset, is dabbed by the title of quite too lovely, while its antithesis, whether used in reference to a public calamity or a bad floor at a dance, is pronounced to be quite too dreadful. Any act of kindness bestowed upon this young person wins from her the remark that such attention is truly affecting, and with this pet phrase, and a few more lovelys and preciouses, varied and qualified by the word quite and too being prefixed to them either singly or together, she manages to rub along very well. . . .The good talker has gone out of fashion, and would now be voted a prosy old bore; it is not the fashion to be careful about the way you express a thing, or to appear to be giving yourself much trouble in entertaining your hearers. The words of the modern young man come out in disjointed fragments--much as one might expect a Dutch doll to talk was it blessed with the power of speech; his sentences seem as if they dropped out of his lips without his own v olition.He has one favorite word at a time, and he wears it threadbare. If you can understand it, all the better for you; if not, you would not like to show your ignorance by asking; so the young man distinctly scores one there. His pet phrase covers his ignorance or his laziness, and he is borne along with the tide instead of having to row against the stream.(Pet Expressions.

Should Intelligent Design and/or Creationism Be Taught...
There are many controversies in courtrooms about whether or not should intelligent design should be taught alongside evolution in public schools, which has been going on for a great amount of years. Intelligent design is the idea of natures changes cannot be a random process, but a type of guidance must have lead to why nature is the way it is in todayââ¬â¢s era. In most cases, that specific guidance is God. God has created the world for a purpose. Creationism is the same idea as intelligent design, believing that nature was created by a divine being, God. Evolution is the idea of natural selection. This idea means that specific characteristics of genes, has been chosen to last longer throughout generations having the ability to breed on those characteristics. Having those particular types of genes, allows the specific living organism to survive longer and be well adapted to itsââ¬â¢ environment. Intelligent design and/or creationism are different from evolution, leading to why these two ideas should not be taught alongside with one another. The ideas should not be taught alongside with each other because it violates the first amendment, separation of church and state, intelligent design is made of theories of religion and not science, and it can intervene with students prior science knowledge.

Student Government At Houston Community - 826 Words
Four students voted in favor of changing the fundamental structure of student government at Houston Community College. The motion passed. The amendments to HCCââ¬â¢s United Student Council constitution is changing the student government system from Student Appointed Representatives to a senator system akin to how the University of Houstonââ¬â¢s student government operates. The change cuts out one layer of student government, and is intended to make student government officers more accountable and cooperative district-wide. ââ¬Å"The only change that is happening is that we will no longer have Student Appointed Representatives,â⬠explained United Student Council President Josue Rodriguez. Instead, students will directly elect their representativesâ⬠¦show more contentâ⬠¦When transformation started, all student organizations became district-wide organizations, so technically HCC has had seven operational district-wide student government organizations for the past two years. This change means that the student government at HCC will start operating more like a single student government organization, not seven. There were nine students and two student life advisors at the special United Student Council meeting on Wednesday, April 5 when the vote took place. After some rewording of the amendments, five students voted: one abstained and four voted in favor. The three students present who were USC executive officers could not vote. The meeting started late as they group waited for the last student to arrive so quorum could be met. The vote to amend the USC Constitution took place after the group voted to suspend the normal parliamentary rules of order. Although the meeting took place at their normal meeting room on the second floor of the HCC Administrative building at 3100 Main, it wasnââ¬â¢t their normal meeting day. It was changed from their usual Friday meeting day to a Wednesday for student government officers who were at a convention. Those officers still didnââ¬â¢t attend.

Results and Discussion Kind of Milk| Taste| Color| Texture| Smell| Low- fat milk| Yogurt-like| Beige| Smooth| Sour| Full-cream milk| Very Sour| Beige| Thick| Very sour| In the table above, the reason why there were only 2 kinds of milk is because 2 groups used low fat milk and the other 2 used full-cream milk. As being compared from the table above, using full-cream milk caused the taste and the smell of the product (yogurt) to be extra sour. We will write a custom essay sample on Lab Report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Yogurt is naturally sour because of the acid present in it. Also, the full-cream milk caused the texture to be thicker compared to the yogurt used with low-fat milk. Even though different kinds of milk were used, the color of the yogurt was the same, which was Beige. IV. Conclusion Based on the given results and discussion of the data, the characteristics (taste, color, texture, and smell) of the yogurt will depend on what kind of milk will be used for the yogurt making process. V. Recommended If one were to do the same experiment above, the group would recommend that they use low-fat milk to make their own yoghurt.

Empirical means ââ¬Å"based on experimental evidence. â⬠* Experimental Design The reaction that occurred was the reaction of the elements Zinc (Zn) and Chloride (Cl) by mixing a piece(s) of Zinc and 50mL of Hydrochloric Acid (HCl). The amount of Zinc was determined to be between 1. 00g and 1. 25g. As the reaction occurred there was still water left in the beaker. In order to remove the water we heated the beaker to evaporate it. The Zinc Chloride then formed as a solid white substance. * Observations As the Zinc and Hydrochloric Acid reacted, bubbling and fizzing occurred. The water became cloudy as the Zinc began to decompose and break apart. The Hydrogen in the Hydrochloric Acid was being released as vapors. * Data amp; Evaluation The mass of our beaker was 58. We will write a custom essay sample on Lab Report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 78g. Our piece of Zinc was massed at 1. 24g. Therefore, the combined mass of the beaker and Zinc was 60. 02g. After the reaction and heating, the combined mass of the Zinc Chloride and the beaker was 61. 39g. We heated the substance again to remove any excess water. The combined mass of the beaker and Zinc Chloride was then 61. 36g. To find the mass of the reacted Zinc Chloride we subtracted the mass of the beaker (58. 78g) from the total and the mass of the Zinc Chloride came out to be 2. 58g. Subtracting the mass of the Zinc (1. 24g) from the Zinc Chloride mass, we found the mass of just the Chloride was 1. 34g. * Conclusion To find the Empirical formula we first needed to find the number of moles of each element per the mass of each element. You must divide the obtained mass of an element by the atomic weight of that element. 1. 24g Zn ? 1 mol Zn65. 4g Zn= . 018 mol Zn 65. 4g represents the atomic weight of the Zinc on the periodic table 1. 34g Cl ? 1 mol Cl35. 5g Cl= . 037 mol Cl .018 mol Zn. 018 mol Zn=1 . 037molCl. 018molZn=2. 05 The empirical formula of Zinc Chloride is ZnCl2. 05. The accepted formula for Zinc Chloride is ZnCl2. Our answer may be slightly off because of there may be leftover water that was not evaporated. As a result, the mass of the Chlorine would be higher and that would make the moles of Chlorine higher, causing the ratio of Chlorine to Zinc to be slightly higher than 2. Another error that could have been made is if the Zinc Chloride was heated too much and it began to release chlorine. Do so would make the mass of chlorine decrease, which would make the moles of Chlorine decrease and the ration of Chlorine to Zinc be slightly lower than 2. Lab Report free essay sample ABSTRACT This test (ASTM C136-06) determines the grading of materials being used as aggregates using two parameters (coefficient of uniformity and gradation) from particle-size distribution curve. Sieve analysis consists of shaking the sample through a set of sieves that have progressively smaller openings. To conduct a sieve analysis, samples are oven dried for at least 24 hours. The soil is placed and shaken through a stack of sieves with openings of decreasing size from top to bottom. The mass of particles retained in each sieve is determined. Results showed that the particleââ¬âsize distribution curve of coarse aggregate is characterized by a steep curve. This means the coarse aggregate is poorly or uniformly graded with small variation in size. Particle-size distribution curve of fine aggregate is characterized by an S-curve. It is well graded and has a gradation of particle size that spans evenly the size from coarsest to finest. Conclusions drawn from the interpretation of the particle-size distribution curve is supported by computed coefficients of uniformity and gradation which is 6. We will write a custom essay sample on Lab Report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 79 and 1. 03 for (well graded) fine aggregates, and 1. 57 and 1. 05 for (poorly graded) coarse aggregate. Significance of the Experiment Particle size analysis is important because it determines the soil gradation, which is an indicator of other soil properties such as compressibility, shear strength, and hydraulic conductivity. A poorly graded soil will have better drainage because of more void spaces. A well graded soil is able to be compacted more than a poorly graded soil. Standard Reference ASTM C136-06 Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates1. Pennsylvania, US: ASTM International, 2006. I. OBJECTIVES After performing this test, the students are expected to: 1. Determine the percentages of various size fraction on the basis of the total mass of the initial dry sample. 2. Determine effective grain size after plotting particle size distribution curve (percent finer versus particle diameter in millimeter). 3. Calculate coefficient of uniformity and curvature and classify aggregates into well graded or poorly graded aggregates based on given criteria for these two parameters. II. EXPERIMENTAL PROCEDURE A. Materials and Equipment Sieves No. 4, 8, 16, 30, 50, 100, and 200 for fine aggregates Sieves No. 1-in. , 3/4-in. , 1/2-in. , and 3/8-in. for coarse aggregates Balance accurate to 0. 1-g for fine and 0. 5 for coarse aggregates Oven Brush B. Methodology 1. Preparation of the Soil Sample. Minimum of 300-g fine and 5-kg coarse aggregates are obtained. These samples are both oven dried for at least 24 hours. 2. Preparation of Equipment. All mass of sieves including the pan are determined. Then, sieves are nested in order of decreasing size of opening from top to bottom. 3. Sieving. The sample is placed in top sieve. The sieves are agitated by hand in a vertical and lateral motion. 4. For course aggregates, the sample is split into two or more batches, sieving each batch individually. The mass of the several batches retained on a specific sieve are combined before calculating the percentage of the sample on the sieve. 5. Sieving is continued for a sufficient period and in such manner that not more than 1 % by mass of the material retained on any individual sieve will pass that sieve during 1 minute of continuous hand sieving. 6. The mass of each size increment is determined on a balance. The total mass of the material after sieving should check closely with original mass of sample placed on the sieves. NOTE: If the amounts differ by more than 0. 3 %, based on the original dry sample mass, the results should not be used for acceptance purposes. C. Data Analysis 1. The mass of soil retained in each sieve is computed by getting the difference of mass of sieve with the retained soil, and the product of no of batches made and the mass of sieves. 2. The percent retained is computed by getting the ratio of mass of retained soil on each sieve, and the initial mass of the sample. 3. The percent finer is computed by getting the sum of mass of soil retained on smaller sieves, subtracting it from the total mass of sample, and dividing the sum by the total mass times 100. 4. Percent finer is plotted on y-axis while the particle size diameter in logarithmic scale is plotted on x-axis. A curve connecting the points is drawn. Logarithmic scale is used to represent grain size information that typically spans many orders of magnitude. 5. Important parameters in computing coefficient of curvature and uniformity such as effective grain size (D10), D30, and D60 are determined from the particle size distribution curve for fine and coarse aggregates. III. RESULTS OF EXPERIMENT Particle-Size Distribution Curve and Determination of D60, D30, and D10 Figure 1. Particle-Size Distribution Curve (Fine Aggregates) Figure 2. Particle-Size Distribution Curve (Coarse Aggregates) IV. DISCUSSION Effective Grain Size (D10). It represents a grain diameter for which 10% of the sample will be finer than it. It can be used to estimate the permeability. The effective grain sizes in fine and coarse aggregate in this test are 0. 14 mm and 10. 4 mm respectively. These values are obtained from the particle size distribution curve shown in Figures 1 and 2. Coefficient of Gradation (Cc). This parameter (also called as coefficient of curvature) can be expressed as: where; D10, D30, and D60 = the particle-size diameters corresponding to 10, 30, and 60 %, respectively, passing on the cumulative particle-size distribution curve. Fine and coarse aggregates are thought to be well graded if their coefficient of curvature (Cc) is between 1 and 3. The calculated coefficient of gradation is 1. 03 for fine and 1. 05 for coarse aggregates. Coefficient of gradation is only one criterion in grading aggregates. Gradation also considers uniformity coefficient which will be discussed in next section. Uniformity Coefficient (Cu). This is defined as ratio of the diameter of a particle of a size that is retained in sieve that allows 60% of the material to pass through, to the diameter of a particle of a size that is retained in a sieve that allows 10% of the material to pass through. This can be simply expressed as: An aggregate is thought to be well graded if the coefficient of uniformity (Cu) is greater than 4 for coarse (gravel) and 6 for fine aggregate (sand). Calculated values for this parameter are 6. 59 and 1. 57 for fine and coarse aggregate. Classification. Coarse aggregate is composed mainly of gravel and crushed stones which pass 3-inches sieve but are retained on No. 4 sieve. Fine aggregates is mostly sand which passes No. 4 sieve but are retained on No. 200 sieve. The experiment showed that the samples used are poorly graded gravel and well-graded sand. Both of the aggregate pass the criteria for coefficient of gradation which value should lie between 1 and 3. Fine aggregate is well graded sand with uniformity coefficient greater than 6. Coarse aggregate coefficient of uniformity is very small and did not exceed 4. Coarse aggregate sample is poorly graded gravel. V. LABORATORY SUGGESTIONS Suggestions for Laboratory Improvement Here are some of my personal suggestions that I believe will help in improving the laboratory: Acquire New Lab Materials/Repair Old Materials. Some of the materials in the laboratory really need repair or replacement. Use and borrowing of some materials and equipment are sometimes on a first-come, first served basis because of limited availability. VI. SUMMARY AND CONCLUSION Coarse aggregate is composed mainly of gravel and crushed stones while fine aggregate is composed of sand. Particleââ¬âsize distribution curve of coarse aggregate is characterized by a steep curve. This means the coarse aggregate is poorly graded (uniformly graded) and has small variation in size. Particle-size distribution curve of fine aggregate is characterized by an S-curve. Fine aggregate is well graded and has a gradation of particle size that spans evenly the size from coarsest to finest. This conclusion is supported by computed coefficients of uniformity and gradation which is 6. 79 and 1. 03 for (well graded) fine aggregates, and 1. 57 and 1. 05 for (poorly graded) coarse aggregate. Manual sieving procedures can be ineffective because the amount of energy used to sieve the sample is varying. Over-energetic sieving causes erosion of the particles and thus changes the particle size distribution, while insufficient energy fails to break down loose agglomerates.

Lab report free essay sample Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic, hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure, indicating that the net movement of water moves into the said solution whereas a hypertonic solution is one with a higher osmotic pressure, thus the net movement of water will be leaving the hypertonic solution. Lastly, an isotonic solution entails no net movement of water across a semi-permeable membrane as the two substances involved display osmotic equilibrium. AIM To observe the effect of solutions different levels of NaCl concentration on potatoes, considering the process of osmosis METHOD (see ââ¬ËPotato Osmosisââ¬â¢ ââ¬â exercise document) Generally rigid in structure although slightly bendy Pale yellow in colour Moist All strips appear the same/similar in structure and size at this point Observations ââ¬â Post-Extraction Strips immersed in 1. We will write a custom essay sample on Lab report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page 0M NaCl Solution are very soggy, soft and appear shrunken Strips immersed in 100% H2O are very rigid, swollen, turgid and appear larger/longer they are slightly bent and cannot be straightened due to their rigidity Strips become progressively soggier as the solutions they are immersed in are higher in concentration of NaCl (Fig. 2) Potato strips from the same potato arranged inà descending order of concentration to demonstrate the differences in structure post-extraction. Thus, we can state that there appears to be a negative correlation between NaCl concentration and the mass and length of the potato strips, clearly evident in the above graph which shows an exponential decrease in both mass and length. This can also be initially seen in the post-extraction observationsà where it is evident that the potato strips immersed in lower NaCl concentration were far more turgid than those immersed in 100% NaCl solution which were flacid and fragile (see strip-comparison in Fig. 2). This occurrence can be explained through the process of osmosis. As mentioned in the introduction, a hypertonic solution is one with higher osmotic pressure meaning that the net movement of water leaves the solution. This would explain the physical changes ââ¬â the increase in mass and length as well as the increase in turgidity in the potato strips immersed in 100% H2O solutions or low NaCl-concentration solutions. Since the solution it is submerged in is higher in concentration in water molecules, or hypertonic, the water molecules will diffuse into the area of lower H2O-concentration (the potato strip) in order to achieve equilibrium. Alternatively, the decrease in mass and length in the potato strips submerged in highly concentrated NaCl solutions can be explained by its immersion in a hypotonic solution. Hypertonic solutions, as mentioned Potato Osmosis Biology SL ATh before, are described as those with lower osmotic pressure, indicating that the net movement of water moves into the solution. Therefore, as NaCl solution is less concentrated in H2O molecules than the potato strips, the decrease in mass and length and loss of turgidity results from the net movement of water leaving the potato strips, which is higher in osmotic pressure, and diffusing into the solution. Nevertheless, there are several possible sources of error that could have greatly or negligibly affected the outcome of the experiment. First, we must note the varying external factors resulting from an uncontrolled environment ââ¬â the biology classroom. Primarily, these would include varying temperatures and humidity which could potentially affect the rate of osmosis as increased temperature results in increased diffusion while increased humidity results in an increased number of water molecules. Secondly, we must note the human errors involved, for example, miscalculations in experimental preparations. These would include the miscalculation of solutions leading to an inaccurate concentration of NaCl as well as the possibility of impurities in the NaCl concoction in the first place while imprecise cutting of the potato strips couldââ¬â¢ve affected the surface area and thus the rate of osmosis. This leads us to the errors resulting from variances in the substances used. As already discussed previously, differences in surface area of each potato strip caused by imprecise cutting as well as the marks (lines and notches) imprinted wouldââ¬â¢ve affected the rate of osmosis while the concentration gradient between each potato strip is likely to differ as well. This stems from the differences in water content of each potato, as, for example, a potato with high water concentration in highly concentrated NaCl solution would have a faster rate of erosion. Further affecting factors could include barriers to diffusion such as the size of pores which would also determine the rate of osmosis. All the mentioned errors above hold the possibility of skewing the data. Subsequently, such errors could have an effect on the reliability of the results. The level of accuracy which has been used throughout this investigation would come into question as a combination of these errors would not permit such precision. Values of percentage change have been taken at two decimal places corresponding with the actual values of mass and length, however, this could be seen as far too precise. A better option would have been to take percentage change as whole numbers or at one decimal place. Nevertheless, we attempted to reduce the potential errors through several measures. With surface area, a cork borer was used in order to uniform the size of the potato strips while the varying concentration gradients were controlled through the completion of several trials (three trials with three potatoes) in order to limit error. Furthermore, to control the effects of the external environment, foil was secured over the beaker containing the submerged potato strips. However, if we refer to the graph, we can see the minimum and maximum spread for each data-point is generally close-set while the R2 value, which calculates the spread of the datapoints from the line of best fit, are both relatively high ââ¬â both around 0. 9. This demonstrable trend indicates a limiting of the amount of error, and thus fairly reliable results despite possible errors. Overall, the resultsà ultimately seem reliable although it mightââ¬â¢ve been even more reliable by reducing the level of precision (decimal places) when recording it. Ultimately, potential improvements will stem from attempting to reduce the amount of error in this investigation, particularly involving controlling the external environment and the miscalculations. To control the external affecting factors, the solution containing the potato strips can be kept overnight instead in a controlled environment with consistent temperatures and humidity. Limiting the human error would be difficult and time-consuming as this would involve Potato Osmosis Biology SL ATh highly-precise instruments or even more focus dedication from the experimenter during preparation. Finally, nothing can be done to uniform the response of the materials used, thus the completion of even more trials limits the potential error and allows the formation of generalizations. Despite the improvements proposed, those relating to limiting human error and completing more trials may prove to be futile as they are not only time-consuming, but the demonstrable trends resulting from this experiment indicate that no further improvements are necessary to reach the desired conclusion. Having established that there is no real need to pursue drastic improvements for the initial experiment, we can now proceed to discuss possible extensions to the investigation. While we already know the results of osmosis on a potato, we may now wish to better understand it. This can be done by recording the progress of the potatoââ¬â¢s transformation either (a) over a period of time (perhaps 24 hours) or (b) until it has reached the point of equilibrium. The mapping of this progress would involve the periodic removal of the samples in order to measure its mass and length, after which it can be compiled into a graph to chart the transformation under osmosis. Alternatively, we could compare the progress of a potato to another type of vegetable or fruit in order to ascertain water content of each. Lastly, the submerged potato strips may be subjected to different kinds of environment, particularly, varying humidity and temperature, without the protection of a foil cap. This would reveal how much of an impact environmental factors would have on the osmotic process and how would the effects manifest. In relation to the question of the sailor, this could represent the life-span one would expect when trapped in certain climates. Lab Report free essay sample In this experiment, we fix the time which is 5 second to collect the amount of the water. At the same time, we also observe the characteristic of the flow whether is it laminar, transition and turbulent flow. THEORY: Reynolds number basically determines the transition of fluid flow form laminar flow to turbulent flow. When the value of Reynolds numberà is less than 2300, laminar flow will occur and the resistance to flow willà be independent of the pipe wall roughness (e). Meanwhile, turbulent flow occurs when the value of Reynolds number is exceeding 4000. For large viscous force, whereby Re value is less than 2300, viscous effects are great enough to damp any disturbance in the flow and the flow remains laminar. The flow is called laminar because the flow takes place in layers. Any combination of low velocity, small diameter, or high kinematic viscosity which results in Re value of less than 2300 willà produce laminar flow. We will write a custom essay sample on Lab Report or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page As Re increases, the viscous damping of flow disturbances or perturbations decreases relative to the inertial effects. Because of a lack of viscous damping, disturbances are amplified until the entire flow breaks down into in irregular motion. There is still a definite flow direction, but there is an irregular motion superimposed on the average motion. Thus, for turbulent flow in a pipe, the fluid is flowing in the downstream direction, fluid particles have an irregular motion in addition to the average motion. The turbulent fluctuations are inherently unsteady and three dimensional. As a result, particles which pass though a given point in the flow do not follow the same path in turbulent flow even though they all are flowing generally downstream. Flows with 2000 lt; Re lt; 4000 are called transitional.
