Science Investigatory Project Essay Abstract The pineapple is one of the leading products in the Philippines, as it thrives in tropical climates. However, the pineapple peelings have low commercial value and are therefore merely thrown away, contributing to the Philippines waste problem. This study entitled â€Å"Saccharification of Pineapple Ananas comosus peelings through Dilute Acid Hydrolysis† was conducted to know the concentration of sugar content which can be used for other purposes like bioethanol. Three samples were used, each sample was composed of two trials; S1T1 (60 degree Celsius for 30 min. ), S1T2 (60 degree Celsius for 60 min.), S2T1 (70 degree Celsius for 30 min.), S2T2 (70 degree Celsius for 60 min.), S3T1 (80 degree Celsius for 30 min.), S3T2 (80 degree Celsius for 60 min). The phenol- sulfuric acid method was used to determine the concentration of sugar content present in the substrate. The test revealed that the dilute acid hydrolysis is an effective way and can saccharify pineapple peelings based on the standard curve. However, the temperature and time was found out that they both have no significant difference in yielding greater concentration of sugar as what as the statistical analysis revealed using Kruskal-Wallis test and Mann Whitney U-test. INTRODUCTION Background of the study Pineapple (Ananas comosus) is the common name for a tropical plant and its edible fruit which are coalesced berries. Pineapples are the only bromeliad fruit in widespread cultivation. It can be grown as an ornamental, especially from the leafy tops. Some sources say that the plant will flower after about 24 months produce a fruit during the following six months while others indicate a 20-month timetable. Pineapple is eaten fresh or canned or juiced. It is popularly used in desserts, salads, as a complement to meat dishes and infruit cocktail. The popularity of the pineapple is due to its sweet-sour taste containing 15% sugar and malic and citric fruit acids. It is also high in vitamin B1, B2, B6 and C. Its protein-digesting enzyme bromelain seems to help digestion at the end of a high protein meal. In the Philippines, pineapple leaves are used as the source of a textile fiber called pià ±a. The pineapple is a herbaceous short-lived perennial plant which grows to 1.0 to 1.5 metres ( 3.3 to 4.9 ft) tall. The plant only produces one fruit and then dies. Commercially suckers that appear around the base are cultivated. It has 30 or more long, narrow, fleshy, trough-shaped leaves with sharp spines along the margins that are 30 to 100 centimetres (1.0 to 3.3 ft) long, surrounding a thick stem. In the first year of growth the axis lengthens and thickens, bearing numerous leaves in close spirals. After 12 to 20 months the stem grows into a spike-like inflorescence up to 15 cm long with over 100 spirally arranged, trimerous flowers, each subtended by a bract. Flower colours vary, depending on variety, from lavender, through light purple to red. The ovaries develop into berries which coalesce into a large, compact, multiple accessory fruit. The fruit of a pineapple is arranged in two interlocking helices, eight in one direction, thirteen in the other, each being a Fibonacci number. (http://en.wikipedia.org/wiki/Pineapple) Saccharification is the process of breaking a complex carbohydrate into its monosaccharide components. It is the hydrolysis of carbohydrates such as cellulose and starch. It increases hydrolysis rates by reducing product inhibition of enzymes and reduces tank usage by combining the processes into one (http://www.merriam-webster.com/dictionary/saccharification) Phenol Sulfuric Acid Method is an example of a colorimetric method that is widely used to determine the total concentration of carbohydrates present in foods. A clear aqueous solution of carbohydrates to be analyzed is placed in a test tube, then phenol and sulfuric acid are added.The solution turns a yellow- orange color as a result of the interaction between the carbohydrates and phenol. The sulfuric acid causes all non- reducing sugars to be converted to reducing sugars so that this method determines the total sugar present. This method is non- stoichemetric and so it is necessary to prepare a calibration curve using a series of standard known carbohydrate concentration (http://www.merriam-webster.com/dictionary/phenol-sulfuric acid method). Dilute Acid Hydrolysis is a process of hydrolyzing lignocellulosic materials by subjecting dried lignocellulosic material in a reactor to a catalyst comprised of a dilute solution of a strong acid to lower the activation energy of cellulose hydrolysis and ultimately obtain higher sugar yields (http://www.merriam-webster.com/dictionary/dilute acid hydrolysis). Statement of the Problem This study aims to saccharify pineapple Ananas comosus peelings through dilute acid hydrolysis. Specifically, the study attempts: 1. To know whether the dilute acid hydrolysis is an effective way of yielding concentration of sugar from pineapple peelings; 2. To determine whether the temperature has an effect on the concentration of sugar; 3. To determine whether the length of time of reacion can affect the concentration of sugar that will be obtained. Hypothesis: 1. The dilute acid hydrolysis is an effective way of yielding a greater concentration of sugar. 2. The higher the temperature of the solution, the greater the concentration. 3. The longer the time of reaction, the greater the concentration of sugar that will be obtained. Significance of the study On average, 435,000 metric tons of pineapples are produced annually in the Philippines, which is one of the country’s leading commercial fruit products. However, there are a lot of unused excess parts of the pineapple, notably the peelings, which are considered as waste and contribute to the country’s garbage problem. This study aims to utilize pineapple peelings as a substrate for Saccharification process through dilute acid hydrolysis. By means of this, the concentration of sugar present in this biomass can be determined which can be use for other purposes and for other studies such as producing bioethanol or even biofuel. Scope and Limitation This study is limited to the use of pineapple Ananas comosus peelings as a substrate for the saccharification process. The peel samples were bought from the market. The experiment was conducted at Chemical Engineering where the chemicals and other laboratory materials were obtained located at University of the Philippines at Los Baà ±os, Laguna from November to December 2010. The study focuses only on the determination of the concentration of sugar present in the pineapple peelings. Definition of Terms Absorbance- is defined as the ratio of the radiant flux absorbed by a body to that incident upon it. Glucose- is called as a simple sugar or monosaccharide Saccharification the process of breaking a complex carbohydrate (as starch or cellulose) into its monosaccharide components Spectrophotometer- consists of two instruments, namely a spectrometer for producing light of any selected color (wavelength), and a photometer for measuring the intensity of light. Sulfuric acid (H2SO4) is a clear, colorless, odorless, viscous liquid that is very corrosive. Sugar- is a term for a class of edible crystalline carbohydrates, mainly sucrose, lactose, and fructose characterized by a sweet flavor. In food, sugar almost exclusively refers to sucrose, which primarily comes from sugar cane and sugar beet. Standard curve- is a quantitative research tool, a method of plotting assay data that is used to determine the concentration of a substance. It can be used in many biological experiments.

Impact of Gunpowder

Impact of Gunpowder A Technology That Marked Major Progress Milestones in History GUNPOWDER INTTRODUCTION Technology is a group of learning committed to making instruments, handling activities and extricating of materials. Everyone have their own way of understanding the meaning of technology or in another word innovation. People use innovation to develop their capacities, and that makes humans as the most vital piece of any mechanical framework. Innovation can allude to techniques running from as basic as dialect and stone devices to the complex hereditary building and data innovation that has risen since the 1980s. These advances invigorated social orders to embrace better approaches for living and administration, and in addition better approaches for understanding their reality. One of that innovation completely changed the world was gunpowder. Gunpowder, also known as black powder, is the earliest known chemical explosive which was invented in china by a Chinese alchemist mistakenly. It is a blend of sulphur, charcoal, and potassium nitrate (saltpetre). The carbon from the charcoal in addition to oxygen shapes carbon dioxide and vitality. The response would be moderate, similar to a wood fire, with the exception of the oxidizing operator. Carbon in a fire must draw oxygen from the air. Saltpetre gives additional oxygen. Potassium nitrate, sulphur, and carbon respond together to shape nitrogen and carbon dioxide gasses and potassium sulphide. The expanding gases, nitrogen and carbon dioxide, gives the propelling action. Gunpowder tends to create a considerable measure of smoke, which can hinder vision on a front line or lessen the visibility of firecrackers. Changing the proportion of the component influences the rate at which the explosive consumes and the measure of smoke that is delivered. (ThoughtCo, 2017) As per legend, during the Tang dynasty (9th century) this Chinese chemist was searching for a formula to make the remedy of life, or the mythical potion for immortality. Despite the fact that it was an accident, when they found the powder was exceptionally combustible, or consumed effectively, they chose to call it fire pharmaceutical. Not long after the disclosure, the Chinese weaponized the substance, or made weapons out of it, and during the time they would make numerous weapons utilizing gunpowder, including rockets, bombs, flamethrowers, and land mines before making guns and firearms. The most established weapon that utilizations explosive goes back to a bronze handheld gun made in north-eastern China in 1288. (Nathans Design Dissertation, 2017) Even though the earliest record of written formula for gun powder appeared in Song dynasty (11th century) this is listed as one of the four great invention in Chinese history. In any case, once the Chinese made sense of that it had dangerous capacities, they squandered no time in fusing it into their military. The Chinese could make a jump in military innovation and went from the standard sword and bows and arrows to a military with mines and flamethrowers. With the disclosure of gunpowder came the innovation of the fire arrow, an arrow with gunpowder on its tip, in the year 989. Roughly 11 years after the fire arrow, in 1000, the Chinese designed the flame thrower. The utilization of weapons be that as it may, did not rise in China until the mid-fourteenth Century. The military development that happened inside China in view of the black powder permitted China to have a more grounded and more propelled military, prompting a general more secure nation. (AP World History 2012-2013, 201 7) After the Mongols attacked China in the mid-13th Century, they proceeded with their conquests into India. In 1221, when the Mongols attacked India, they carried with them the information of gunpowder from China. By the 18th century, the Indians were able to make Mysorean rockets; the main iron cast rockets to be utilized by any military on the planet. But the secret of the gunpowder didnt stop spreading to the Middle East. From India, the gunpowder spread to the Middle East in the vicinity of 1240 and 1280. The last place to reach gunpowder was Eastern Europe. Like in India and the Middle East, it was brought into the area in view of the Mongol attacks. In any case, a portion of the learning of gunpowder was likewise transmitted to Europe through the Silk Road. At the point when the Europeans exchanged with the Middle East, the learning of gunpowder was carried into Europe alongside the exchange of merchandise. After getting the knowledge of gunpowder European chemists was interested in searching other alternative methods to improve the qualities of chemical contains. As a result of that European chemists made corned explosive. Corned black powder contained an indistinguishable chemicals from typical explosive however the refining procedure included blending the explosive into a wet substance and after that drying the blend. A German monk, Berthold Schwarz, is credited with developing the principal European gun in 1353. Guns which had been originated in China or the Middle East were enh anced by Europeans. Propelled European metal work strategies permitted European metalsmiths to make more long lasting and sturdy rifles; they likewise figured out how to compute the measure of drive of the gas in the load of the weapon. This learning help make weapons that shot more noteworthy separations. Europeans were all the while enhancing black powder a century after the Chinese had imagined the primary weapon. The European progressions of black powder would achieve China by a Portuguese ship in 1520. The Portuguese presented the gun, enhanced rifles and other European headways to the Chinese. Many years after the development of black powder the Europeans had given back the substance to its starting point and explosives voyage through Asia had turned up at ground zero. The Movement of Gunpowder from the East toward the West (AP World History 2012-2013, 2017) If someone asks what were the precursor circumstances that acted as the motivation for the technology the answer is the overwhelming need of power. The advancement of gunpowder was vital in fighting first for its mental impacts, as the Chinese utilized flying fire (explosive arrow) against their Mongol foes. At the point when the innovation relocated toward the West, notwithstanding, its genuine esteem was in its capacity to control fatal attack weapons and in the end put precise capability in the hands of common troopers. Prior to the innovation of the gun, attack weapons were huge, unwieldy and hard to build. Gunpowder as a fuel expanded the force accessible for anticipating rockets toward adversary emplacements, both expanding the harm these weapons could bring about and expanding their exactness also. Whats more, designers called sappers could burrow under adversary fortresses and pack their passages with gunpowder, bringing out stronghold dividers with unstable power. The scalin g down of gun into guns gave a comparative damaging capacity to normal fighters on the ground, permitting them a considerably more noteworthy successful range than they had with their past bows and crossbows. Guns likewise required less preparing than longbows, and the fast shots could even puncture the plate protective layer worn by knights of the time. At last, gunpowder required an entire revaluation of the specialty of fighting, and nations that were ease back to embrace the new innovation paid the cost on the combat zone. Other than military gunpowder were used in civil engineering and mining in early 15th century. The records of using gunpowder in mins come from Hungry in 1627. After that the technology was introduced to Britain by Germans in 1638. Other than mining gunpowder were used in the construction in canals and tunnels. The first gunpowder is not utilized today with the exception of in firecrackers and sparklers or as a boosting fuel for rocket launching. Like how it was for the most part utilized hundreds of years prior. It has been supplanted by a prevalent synthetic compound and utilized for the most part in slugs. A great deal more propelled mixes are utilized for explosives. One could state that the first gunpowder was the beginning stage for these current mixes. The most recent uses of gunpowder was Afghanistan war in 2001 which killed over 2000 and 22000 wounded, Korean war 1950-1953 which killed over 1800000 and 220000 wounded and world war 2 (1939-1945). Explosive has influenced todays general public by taking a great many lives and damaging a huge number of others. Gunpowder has additionally destroyed the lives of numerous families and companions of the casualties of contention. If this innovation didnt exist then there was a chance of preventing the wars and saving number of lives that co uldnt even count. On the opposite side of the gunpowder has likewise been utilized to make firecrackers which have conveyed extraordinary happiness to the world. If this technology has taken away the invention that found based on gunpowder wouldnt be able to reach to the mankind or use it for the present manufacturing processes. In spite of the fact that gunpowder and its present day subsidiaries do in any case have some significant uses today, all ammunition utilized as a part of firearms all through the world is stacked with smokeless powder. Even though the gunpowder was the main known explosive compound until the mid-19th century, present day there are other alternative ways that are in use and still in process. As an example the American navy has been already tested 30-kilowatt LaWS system at sea aboard the amphibious transport and hoping to deploy varieties of the laser weapon framework in the armada by 2020. (Nationaldefensemagazine.org, 2017) Other than laser weapon the alternative weapon system that still in progress is portable versions of rail guns. Besides the rail guns there might be a chance of producing projectile weapons which are electromagnetically accelerated or energy that transferred electronically to the projectile. (Cooney, 2017) When these technologies are known to the society in the future the gunpowder will be forgotten from the usage and the memory. Even though that happens there is a saying that old is gold. Anyone cant predict what will happen in the future. Reference List AP World History 2012-2013. (2017).

George Herbert Mead Early Life Sociology Essay

George Herbert Mead Early Life Sociology Essay Higher Education Mead graduated from Oberlin College in 1883 and matriculated at Harvard from 1887-1888 where he studying philosophy and sociology and graduated with a Masters degree. Although he belonged to a deeply religious family, Mead became a devout naturalist and non-believer after attending college. After leaving Harvard, he participated in many causes and was an ardent activist of any progressive causes. He marched in favour of the womens suffragette and took part in several civic duties in Chicago. The Chicago Philosopers Club 1896 Mead was influenced by Charles Darwins Theory of Evolution which is evident in his theories as a naturalist. At Harvard, Mead studied with Josiah Royce who was a major influence in his life, and  William James, whose children he tutored. In 1888, Mead left Harvard and travelled to Germany. There, he studied with psychologist Wilhelm Wundt who was his influence for the concept of the gesture, which would soon be an important aspect of his work. In 1891 he married Helen Kingsbury Castle. He taught at the University of Michigan and then the University of California. Mead wrote intensively over a 40-year career, however he didnt publish any books. He published over 100 scholarly articles. Mead died of heart failure on April 26, 1931. Following his death, his students put together a collection of his notes, unpublished letters and lessons, and finally published a book of his thoughts and teachings. Epistemology Ontology He observed that people acquired knowledge about behavior based on what they observe and acquire from society. The principle of sociality is the  ontological  foundation of  Meads  concept. The distinction between mind and matter and that between consciousness and the physiological organism is a distinction which is drawn between contents which may appear on either side of the line. Mead noted that there is more than what meets in the eye in terms of human interactions. This means, that there are reasons behind certain actions, which can be brought out through micro-investigations of human interaction. People who influenced Mead Mead was influenced by his friend John Dewey who led him into educational theory. However Meads thinking diverged from that of Dewey and he developed the famous psychological theories of mind, self and society. This idea was also greatly influenced by Wilhelm Wundt; who Mead met when he went to Germany to study psychology At Harvard, Mead studied with an American idealist philosopher Josiah Royce who also was an influence. Mead was influenced by Adam Smith and thus identified the social act of economic exchange. In Meads writing I and the Me Mead takes William Jamess distinction between the I and the Me and develops it further. William James was a renowned pragmatist philosopher. The prominent sociologist Charles Cooley (A philosopher) also influenced Meads thinking. People who were influenced by Mead Herbert Blumer, a sociologist who studied at the University of Chicago was influenced by Mead. He took over Meads lecturing responsibilities and went on to chair the Department of Sociology at the University of California Berkeley. He is often referred to as the heir of George Herbert Mead. During the second half of the twentieth Century, Meads theory of symbolic interactionism was separated into two distinct branches : The Chicago school under Herbert Blumer and the Iowa school under Manford Kuhn. Both of whom were influenced by Mead. Norman Denzin and Sheldon Stryker also continued to develop the Symbolic Interactionism theory of Mead. Ervin Goffmans so-called dramaturgical sociology is also highly influenced by Mead. Major Publications Mind, Self, and Society (1934) The Philosophy of the Act (1938) The Philosophy of the Present (1932) Basic Sociological Concepts Double Centre of Gravity Taking the role of the other Self Development The Self The self emerges from social experience Individual selves are the products of social interaction and not the biological or logical preconditions of the mentioned interaction Hence The self is not part of the body, and it does not exist at birth Explaining further in the absence of social interaction (i.e. isolated children) the body may grow but no self will develop. Social experience involves communication and exchange of symbols Dog example A dog responds to what you do, but humans respond to what you have in mind as you do it. Social interaction involves seeing ourselves as others see us taking the role of the other (Mead). Double Centre of Gravity In Meads concept of the self, he expressed Double Centre of Gravity by dividing the self in to the I and the Me. The I and the Me The I and the Me are derived from the self. The Self is the relationship between I and Me The Me is the internalization of others perspective of ourselves the perspective we get of ourselves from how others treat and interact with us. The I is the part of us that responds to these internalized attitudes.   Explaining further the Me is the social self that takes into account the reactions of others, while the I is the indistinctive part of the self which has ideas and imagination and is independent to social norms. Taking the role of the other Mead suggested that socialization derived primarily from peoples ability to take the role of the other. Taking the role of the other means putting yourself in another persons place to think/reflect about yourself. Taking the role of the other helps to integrate the individual with organized social processes By taking the role of the other, Mead meant putting oneself in the place of another individual in such a manner that one arouses the same response in both. Self Development According to Mead, developing the self is learning to take the role of the other   The first stage is Prep Children imitate and begin to understand symbols such as languages and gestures The Second Stage is Play Children role-play and pretend to be another person. Play involves assuming roles of significant others, helping kids see the world from others points of view. The Third stage is Game Children, at 7 or 8 begin to understand others roles and responsibilities, making games possible. The fundamental difference between the game stage and its antecedent play stage lies in the childs ability to take the roles of multiple people at the same time Generalized Other The norms, values, attitudes and expectations of people in general; the childs ability to take the role of generalized other is a significant step in the development of a self. The individual defines his or her own behavior with reference to the generalized attitude of the social group(s) they occupy. Significant other An Individual who significantly influences someone elses life. i.e. Individuals who are most important in development of the self. (e.g. parent) MEADS CONTRIBUTION TO SOCIOLOGY Mead is one of the most influential and acclaimed sociologist of the 20th Century Praised by Critics throughout the world as a pioneer and a Stalwart Has had several books published posthumously about his teachings the individual mind can exist only in relation to other minds with shared meanings (Mead 1982: 5) CRITICISM THE END

The Art of Testing pH Levels Essay -- Science, informative, educational

This report will examine a variety of methods that can be used to measure the acidity or alkalinity of a solution, also known as its pH level. The scale used to measure acidity and alkalinity is called a pH scale, which measures the amount of H+ ions in a solution. Acids have a pH level below 7; bases have a pH level above 7. Strong acids have the lowest pH levels (0-4) and strong bases have the highest pH levels (10-14). Neutral solutions have a pH of 7 and they are neither acidic nor basic. Distilled water is neutral, because the H+ and OH- ions are balanced. An acid is a substance that produces hydrogen ions in water. When an acid dissolves in water, hydrogen molecules interact with water molecules to form hydronium ions. The strength of an acid is determined by the concentration of hydrogen atoms; the more hydrogen atoms in a solution, the stronger the acid; and, the less hydrogen atoms in a solution, the weaker the acid. Acids generally have a sour taste, react strongly with metals, and become less acidic when mixed with a base. A base is a substance that forms hydro...

Agriculture and Population Growth Essay -- Agricultural Economy Scienc

Agriculture and Population Growth The earth is increasing its population by 90 million people per year, and yet we still have 5.9 billion people left to feed and to give shelter (Mitchell, 1998). Along with the increase in the population, there are also more people on Earth who are living longer lives. The global population boom has coincided with the improvement of health, and of productivity, around the world. On average, the human population today lives longer, eats better, produces more, and consumes more than at any other time period in the past (Eberstadt, 1995). Agriculture feeds people, but will it be able to feed the expanding global population, especially with its exponential increase? One way for the population of today and tomorrow to live in harmony in regards to nourishment provided by the environment is to be able to intensify agricultural yields. With a projected population of 10 billion people, an increase of global average grain yields from 2 to 5 tons of grain per hectare would ensure a per capita diet of 6,000 calories and would save a land area twice the size of Alaska (Waggoner, 1994). Most of the world’s increased output is no longer a result of expansion of area used in agriculture, but resulting from the intensification of production on existing agricultural areas. In the last 50 years, agriculture has intensified and yields per hectare have been rising. Intensification has allowed for a reversal of destruction of land. More land has been spared due to increased intensities. In India, 42 million hectares of land have been spared, approximately the size of California and globally, the world has saved an area the size of the Amazon (Ausubel, 1996). Of all human activities, agriculture transforms the... ... and supported in a sustainable manner, agricultural intensification might just be able to keep up with the demand. In the up-coming decades, we will soon find out. Bibliography Ausubel, Jesse H. 1996. Can Technology Spare the Earth? Scientific American 84; Pages 166-178. Brown, Lester R. 1997.

Lord Byron “When we two parted” Essay

Lord Byron was known for having one forbidden love, which is depicted in his poem â€Å"When we two parted†. The theme of the poem forbidden love comes from the poem itself telling a story about a love affair, and how both cannot coincide with each other, cheating and loving one person. The poem starts off with Byron and his mistress departing from one another, the two lovers now are nothing, but allusions, memories in each other’s mind. Also that they only both left with â€Å"half Broken Hearts†. The poem continues on with Byron informing the readers in the next lines â€Å" Pale grew thy cheek and cold, Colder thy kiss; Truly that hour foretold† That they both left in tears, and then they use imagery to describe the â€Å"morning dew† and how it reminds him of the shame Byron is facing. The shame that the shame that is being referred to in the morning dew is, that you cannot have love affair. Throughout the next verse of Byron’s poem he tells us that his conscious is now getting to him. He is realizing what he has been doing is wrong but he cant admit or tell his mistress that has departed already. He shows the audience he is now feeling the guilt and uneasiness is hard to bare with in this in the next lines: Hear thy name spoken, And share in its shame. They name thee before me, A knell to mine ear; A shrudder comes o’er me– In the lines to come he tells us that he was having an affair and he is now wishing he could take it all back for he knows what he has done is wrong. After he is finished admitting to his wrongdoing he now is faced with the guilt of this for the rest of his life. That he shall never meet his love again. But if he shall meet his love again he would tell her what he has done, but he will now have to live with this guilt for the rest of his life. He expresses these feelings in the closing verse of his poem: in secret we met– In silence I grieve, That thy heart could forget, Thy spirit deceive If I should meet thee After long years, How should I greet thee?– With silence and tears. Loving one means to love only one. You cannot win with two and you should never try. Love is a strong word and only had room for one. In this poem Byron talks about his affair and his lost. You see that he teaches us, no matter how good it feels at first, if you doing wrong, the pain will be even greater.

Gore’s movie, “An Inconvenient Truth” Essay

Former Vice President and former Tennessee Senator Al Gore discusses the correlation between carbon dioxide and other so-called greenhouse gases in the atmosphere and global warming. Gore’s movie, â€Å"An Inconvenient Truth† is constructed to look as though the majority of it is taking place in a college lecture hall, thus implying that his information is indeed fact. Better yet, before the end of the movie, Gore attempts to prove that global warming is not an environmental theory, but is a fact and that it is being caused by things that man is doing. His simple conclusion is that mankind is creating more greenhouse gases and that is causing the earth’s temperature to rise at a rate that might soon be catastrophic. Gore spends a great deal of the movie in front of a double line graph comparing carbon dioxide levels in the atmosphere and the earth’s temperature. He explains where his personal interest in the concept came from, a research professor when he was an undergraduate student, and how the professor’s work has predicted the climbing earth temperatures. Gore never specifically illustrates how mankind is contributing to the greenhouse gases, but he does make allusions to heavy traffic and coal-fired energy plants as the cause. Instead, he uses a very effective melding of classroom instruction and beautiful natural footage of his farm in Tennessee and the ice flows of Antarctica. He even compares the need to do something about global warming to his family’s failure to do something about smoking. Gore points out that until his sister died from lung cancer, his father raised tobacco on their Tennessee farm. It wasn’t until his daughter’s death that he made the connection between his action and her illness. Likewise, Gore said, he is afraid that we will not make the connection between our actions and global warming until our children are dying from it. The use of analogical reasoning is impressive through the film as is the use of pop culture to define his arguments, relying on a clip from the cartoon sit-com Futurama as his explanation of why greenhouse gases lead to heating the environment. The biggest failing of the movie are Gore’s lack of an answer for the problem he presented. He points to the ever-rising global temperature and the melting ice flows in the Arctic, Antarctica and Greenland, but only as the final credits roll are there any suggestions for what to do about it. And these claims are the ones that are least supported. For example, the credits proclaim the advantages of switching to mercury-based florescent light bulbs instead of traditional incandescent light bulbs, claiming that the energy saved by making little changes like that can help offset the growing carbon problem. But he never backs up those claims with facts and never discusses other issues which might be a factor in choosing light bulbs, such as quality of light provided and the fact that fluorescent bulbs contain mercury, a potentially lethal heavy metal. Gore’s explanations seem sound and reasonable, but that may also be due to the way they are presented. With an ice shelf breaking apart before your eyes, it is hard to demand answers about why the shelf is breaking apart. And, no one in the movie ever challenges Gore’s opinions or facts. He claims that when opponents to the global warming theory make objections that he researches them and adds the answer to his lectures, but there is no evidence of this. Instead, it appears that Professor Gore has used his training in academia and politics to make it look as though he knows all the answers, but the real â€Å"Inconvenient Truth† is that the movie leaves you with more questions than answers.
