Teaching Students using Literature - Essay Example Literature has been regarded as the most underestimated subject however it is not so. It helps us reflect our understanding. Literature helps the mind develop and understand situations as students embed themselves in the given scenario coming up to something which they think is more appropriate for the desired case. Literature helps explore societal issues as well and therefore is an important aspect for learning through cognition. Literature helps students make more cognitive decisions and through such comprehension students are able to withstand difficult challenges in the world. Learning through literature has always been a better case as literature provides with the past, the present and sometimes the Future as well. Through reading students can also improve upon their perception about the general world and biases are mostly eliminated through the use of better literature. Engaging into discussion is also a good tactic that makes students learn very well. More will be emphasized as we move along this study. The study aim to cover 5 important aspects of learning through literature and a comprehensive guide on how to tackle students of different grades is also to be dealt with. First we need to understand the student teacher relationship and its importance for the benefit of the student. A solitary mark of a successful teacher is the capacity to use an array of research-based instructional strategies. Strategies enhancing students' performance Researches have identified eight instructional strategies that enhance student achievement. 1. Reinforcing endeavor and providing appreciation: By reinforcing effort and providing recognition, teachers highlight students' efforts that make a difference in their levels of achievement. 2. Summarizing: through this process the students can analyze information, thus strengthening their understanding of the content. 3. Activating former familiarity: moving back in time or highlighting cues which enables the students to learn or experience and thus help activate students' prior knowledge. 4. Homework and practice: this makes a student grasp more upon the material involved. 5. Others include the classroom practices connected with the instructional category of identifying similarities and differences including comparison tasks. 6. Nonlinguistic representations: this is special as students learn more effectively by viewing pictures and other stuff rather tan reading. Nonlinguistic representations can take a variety of forms including graphic representations, physical models, mental pictures, drawings, and kinesthetic classroom activities. 7. Joint learning: group interaction is a tool which accelerates cooperative learning. There are five defining elements of cooperative learning: positive interdependence, face-to-face promoting interaction, individual and group accountability, interpersonal and small-group skills, and group processing. 8. Setting goals: this directs the student to a certain standpoint and feedback is the most important tool of appreciation and direction Goal setting establishes a direction for learning. Involving students in the goal-setting process can increase students' accountability for their own learning.

Sludge Lab Report Essay Example for Free

Sludge Lab Report Essay For the first physical observation, I tried smelling the mixture. It smelled like permanent marker. Next I tried sticking a spoon in it and stirring the tan solid lightly. It looked like it was an extremely smooth sand. Finally, I tried drinking the liquid. Nah, I’m kidding! To start off, I will describe the liquid. I separated it simply by using the decanting technique. I carefully poured it off of the mixture of solids and into a separate plastic cup. Easy. The physical property of phase was used for separation. It was the only liquid in the mixture. Then I had to identify it. I smelled it and it had a permanent marker smell to it. That led me to believe it was an alcohol. Next, I tried measuring the density using a graduated cylinder and a balance. I measured the amount of alcohol I put in the graduated cylinder (volume) and how many grams it was on the balance (mass). The volume was 9. 2cm3, the mass was 7. 25g, and the overall density was . 79cm3. That proved my liquid was not water. Finally, I tested the boiling point to determine what type of alcohol it was. I used a ring stand, thermometer, hot plate, test tube, and a beaker full of water. I placed the beaker full of water on the hot plate. I then filled the test tube with my liquid and attached it to the ring stand. Finally, I put the thermometer in the test tube and turned the hot plate on high. The liquid really started boiling around 78 degrees (Celsius), so I concluded that my alcohol was ethyl alcohol. Next we have the blackish/brownish particle layer. To separate it, I used the magnetic retrieval technique. This tests the physical property of magnetism. I simply used a magnet to retrieve the particles and a toothbrush to remove them from the magnet into a separate paper cup. There’s only one substance that is magnetic, but I had to do two more tests. I simply checked solubility in water in alcohol. It wasn’t soluble in either. It was, obviously, iron filings. The third substance I decided to separate from the mixture was the tan sand. After the liquid was removed, the solid wasn’t as silky and it was more like normal sand. I also discovered the â€Å"rocks† were actually clumps of this substance. ANOTHER thing I discovered was white/clear grains. Yes, it was a salt! That means there’s only one way to separate this stuff: dissolve and filter. I poured water onto the rest of the mixture and stirred it up for a solid minute or so. After that, I poured the water into a funnel lined with filter paper which dripped down into another cup. This left me with only the tan sand. First I tried smelling it. It had a REALLY strong smell. Secondly, I recalled it being in the alcohol with a few particles floating around. This got me to believe it was slightly soluble in alcohol. Finally, I tried testing solubility in water. It just floated at the top without any particles floating around in the water, so it wasn’t soluble in water. Due to these factors, I determined it was sulfur. Last, but certainly not least, the white/clear grains. Before I evaporated the water, I took note that it’s soluble in water. To separate it from the water, I evaporated it off. I simply put it on a hot plate, set it on high, and poof. Only grains. By now I identified it as a salt. My next test was alcohol solubility. Turns out, it’s only slightly because the alcohol was very cloudy after the dissolving process. Lastly, I put a sample on a watch glass with some water and left it out over night to check crystal shape. In the end, the crystals were spear shaped, leading me to the conclusion that it was potassium nitrate. All in all, my sludge consisted of ethyl alcohol, iron filings, sulfur, and potassium nitrate. I think my only difficulty was that I discovered the salt fairly late in the process. Overall, I enjoyed this lab because I really felt like I was doing something a real scientist would do. Oh yeah, and I felt a feeling of loss once I had to throw my work away. Sniff.

Utilitarianism As The Principle Of Happiness Philosophy Essay

Utilitarianism As The Principle Of Happiness Philosophy Essay According to John Stuart Mill (author of Utilitarianism), utility is happiness, and happiness is pleasure minus pain. Widely known as a universal hedonism, utilitarianism is an ethical philosophy in which the most ethical acts are those which serve to increase the happiness for the most people or at the very least, decreases the suffering for the most people. Nonetheless, albeit with the fact that happiness is recognized as a universal though objectively valuable goal , utilitarianism has been for centuries recognized as the doubt of most moral philosophers, criticized for being impractical, cold and distant from individual rights and the real complexities of life. Bernard Williams is one of the critics, who brought about explicit series of objections against utilitarianism in his book, A Critique of Utilitarianism (Williams 1973b). Obviously, it is impossible for me to cover all areas concerning utilitarianism and so concentrating on morality objections, I will first of all attempt to present Bernard Williams integrity objection and the well known counter-examples against utilitarianism. Then, I will try to counter these objections, and rebutted Williams argument with stern objections as well, with Mills Utilitarianism as my reference. At the end of this essay, I hope to show that utilitarianism is indeed right, and likewise, moral intuitions are without a doubt unreliable to be used as a base in criticising utilitarianism. From what I can understand, Williams believes that utilitarianism fails to recognise the reality of complexities in life, the value of integrity, and as I mentioned earlier, individual rights. Morality comes with the recognition of individual rights and if decisions or judgments are made based on numerical value of the greatest number of happiness in a situation, the happiness of this lesser number group is ignored. Hence, integrity failed to be satisfied. In order to maximize the number of happiness, simply favour the largest number of members in a group and this irked the mind of Williams. Moreover, according to Williams, a normal utilitarian man wouldnt be able to fulfil the demanding ridiculous principle of utilitarianism. It is asking too much of an individual person and so because of that the theory must be flawed. From experience itself we can be sure that morality indeed, does not require so much of us.   Yet, the latter argument of Williams can still be argued as it is not that the theory is demanding, it is just that people dont want to fulfil their moral obligations, and that we just dont like being told to do what we dont want to do.   After all, a moral theory that wouldnt ask us to do what we dont want to do would be useless. Critics of utilitarianism have never fail to construct hypothetical situations where in each of them is the definite clear expectation of what the utilitarian would say, and it is also clear that the saying of the utilitarian would always be potentially wrong in almost all hypothetical cases. These counter-examples against utilitarianism do not conclusively show that utilitarianism is wrong, but indeed they are common reasons why people are rejecting it. And so because of that, I will present two such common counter-examples and the expected utilitarian response for these counter examples. First Counter-Example: Hypothetically speaking, there would be a television show of the future, a show where a person is taken and subjected to tortures on the show.   This is a pay-per-view show that costs a good amount of money to get.   Only people who want to see the show will ever see it, but there are a large number of people who get a great amount of pleasure from seeing this plus all the profits go to charity.   This isnt a regular program, it may only happen once.   Should this show be made? Speaking in a utilitarian manner, it is indeed right to give a green light to this show as even though, it is really sad and bad for this one person, it is however, brings a lot of happiness and pleasure to those who will see it (obviously thousands of watchers). Moreover, all the profits will go to the charity thus benefited a lot more people! Clearly, the benefits outweigh the harms. But obviously, it is indeed still wrong to torture people. This could indeed be the main argument of the opponents. Regardless of the benefits, it is still a violation of that tortured mans rights. Furthermore, to enjoy watching the torture could indeed be more morally wrong than to be physically involved in the show. Second Counter-Example: Jim, a botanist travelling in South America, comes upon a public execution in a small town. A military captain has lined up 20 Indians. He explains to Jim that they have been chosen at random from the local population, which has recently been protesting against the government. The captain offers Jim a guests privilege. If Jim wishes, he can select one of the Indians and shoot him; the other nineteen will then go free. Otherwise, the execution by the captains henchman, Pedro, will go as planned. Utilitarianism seems to claim that it is obvious that the right thing to do is for Jim to just select one of these Indians to be shot at, so that another 20 lives could be spared. To not choose, or refusing to choose could lead to unhappiness of 20 persons, whereas to choose could only cause unhappiness of one. And so as we are referring to the theory of maximizing utility, to lose one is better than to lose 20. However, the objector will claim that it is just obvious that this is the wrong thing to do.   Killing a persons life is still wrong for whatever the reason is. From what that I can deduce, the two counter-examples have one thing in common that is our sense of Morality or our moral intuitions clashes with the principles that utilitarianism hold. Indeed, opposite commands. Nevertheless, it does not mean that utilitarianism must be wrong or flawed. First of all, the arguments made by these counter-examples can only be conclusive if only our moral intuitions are correct.   However, as we all know, our moral intuitions are volatile due to the complexities of life and due to the significant numbers of gray areas that could result in confusion, according to Mill, that is why we refer to moral theories in the first place. Since it is unclear to us of the universal approval for moral intuitions, the critics cannot use their moral intuitions as the base for rejecting a moral theory which is in this case, the moral theory of utilitarianism. Indeed, of course, for example, stealing is a disgrace yet to think of it now, maybe our other supposed to be right moral beliefs might be wrong. Yet, is stealing really wrong? What about Robin Hood? Is he a hero or just a plain mere thief? The point that Im trying to state here is that we dont really know which are right and which are wrong. Our moral beliefs are inconsistent.   Some may percei ved certain things are right. Some may not. And so, we cannot know that our common sense moral intuitions about The Torture Show or Jim and The 21 Indians are right mainly because we dont really know which of our moral beliefs to trust. Second of all, the counter-examples are based on complicated moral situations; and truth to be told, biased as have they are design in such a way that the morally right answer seem obvious.   In reference to Jim and the 21 Indians, let me re-describe the situation to highlight the utilitarian benefit. Indeed, it is hard to overlook how terrible the consequences would be if 20 Indians are to be killed, when Jim has the power to prevent that. We must acknowledge the fact that, yes, although it is easy to sympathize with one innocent unfortunate person, we must also sympathize with the other 20 people, each of whom will suffer greatly if they are to be killed.  In this case, the morally right action is not obvious.  The situations presented are almost always unusual and extraordinary they are situations that one is unlikely to come across, much less to be prepared for when one does come across it.   And so conclusively, we based our moral intuitions on our moral educations. Mor al education is applicable to our daily lives and if it was to be applied in aggravating counter-examples and in every possible situation, it is indeed impossible. And so because of that, moral intuitions are not valid and any objections based on them are flawed and can be disregarded. Conclusively, these could somehow rebut the arguments made by William on the basis of integrity and morality. Conclusively, we can actually deduce that things that are morally wrong usually involve the harming of people and things that are of high moral values such as charity work, heroic deeds all contribute to the welfare of the people. Moreover, it is not a coincidence that wrong actions harm people and right action help people.  Indeed, utilitarianism claimed that the reason that right actions are right is that they help people, and the reason that wrong actions are wrong is because they harm people.   The basis of morality is inside the principle of utilitarianism. You make people happy when you help them and you make them unhappy when you harm them. And so, conclusively, as long as a person accepts that it is best to help people as much as possible and hurt them as little as possible, he or she must accept that utilitarianism is right!

Particle Kinetics of Biological Aerosols During Impaction Essay

At the beginning of the 20th century, the study of aerosols, suspensions of solid or liquid particles in a gas, were the forefront of physical science because they represented the smallest observable division of matter. In fact, aerosols contributed to the early understanding of Brownian motion and diffusion, Millikan's measurement of electron charge, and Wilson's cloud chamber experiment for the study of ionizing radiation. During the first half of the century, aerosol research continued, and grew important after World War II and especially during the 1970s and 1980s, during which environmental awareness and a concern for health effects arising from air pollution in community and occupational environments, promoting the development of aerosol technology. The field expanded rapidly in the 1980s, including the involvement of aerosols in high technology production processes and a concern for aerosol contamination. The decade of the 1990s has seen increased research on the properties of ultra fine particles and on the effect of aerosols on global climate. Now, aerosol technology has become an important toll in understanding the effect we have on our environment and the impact of the environment on us. After all, there are multiple aerosols in our own surroundings, such as re-suspended soil particles, smoke from power generation, photochemically formed particles, salt particles created from ocean spray, and the water droplets or ice particles that form clouds, and include a wide range of phenomena such as fume, dust, smoke. Every aerosol varies in their ability to affect visibility as well as our health and quality of life, and understanding the properties of aerosols would enable us to comprehend so many natural processes, such as cl... ...DRUMs like the one displayed below, coating the surface with the sticky covering of your choice, and using a motor to rotate the DRUM, as the particles are drawn in by the vacuum, they are deposited onto the plate, and the plate rotates continuously, preventing the build-up of particles in one area. The dynamics of particle deposition on the circular DRUM are essentially the same as that of the impactor plate, because the width of the nozzle is so tiny compared to the surface area of the curved DRUM, that, despite the curve, in relation to the nozzle, the DRUM is essentially a flat surface.

Electrical Resistance

JMJ MARIST BROTHERS NOTRE DAME OF DADIANGAS UNIVERSITY MARIST AVENUE, GENERAL SANTOS CITY MULTITESTER Instrumentation and Control CpE 511 NAME: KURT RUSSEL C. CHUASeptember 01, 2012 CYNTHIA C. GONZAGADate of Submission INSTRUCTOR: ENGR. JAY S. VILLAN, MEP-EE Introduction A multitester or multimeter is a device which can be used to gather data about electrical circuits. A basic multitester can measure resistance, voltage, and continuity; while more advanced versions may be able to provide additional data.This tool can be very useful to have around the house, and anyone who plans on doing electrical repairs should most definitely use a multitester for safety reasons. Multitesters can be used with the current off or on in most cases, although using the device with the current on can sometimes result in damage to the device. Theory Ammeters are employed for measuring current in a circuit and connected in series with the circuit. As ammeter is connected in series, the voltage drop across ammeter terminals should be as low as possible.This requires that the resistance of the ammeter should be as low as possible. The current coil of ammeter has low current carrying capacity whereas the current to be measured may be quite high. For this reason a low resistance is connected in parallel to the current coil. Voltmeters are employed to measure the potential difference across any two points of the circuit these are connected in the parallel to the circuit. The resistance of voltmeter is kept very high by connecting a high resistance in series of the voltmeter with the current coil of the instrument.The actual voltage drop across the current coil of the voltmeter is only a fraction of the total voltage applied across the voltmeter which is to be measured. An ohmmeter is a measuring instrument used to measure the resistance placed between its leads. The resistance reading is indicated through a mechanical meter movement which operates on electric current. The ohmmeter must th en have an internal source of voltage to create the necessary current to operate the movement, and also have appropriate ranging resistors to allow just the right amount of current through the movement at any given resistance.One major problem with this design is its reliance upon a stable battery voltage for accurate resistance reading. If the battery voltage decreases, the ohmmeter scale will lose accuracy. Conclusion Aside from using devices such as  multitester, the resistance value of a  resistor can be determined by its color coding. There are small differences between measured and color coded values of the resistances. These differences may be caused by some factors such as the multitester used in the experiment and some mistakes made by the experimenters.It is much easier to read the resistance value of a resistor through a digital multitester than by using an analog multitester and by color coding. In addition, in using an analog multitester, you have to first consider the range of the resistance and make the zero-ohm adjustment in each and every reading. In that case, that is the only time you  can acquire the resistance value after a  slight inconvenient process.

Free Essays on Subliminal Messaging

The Advertising Persuasion: A Brief Overview of the Practices and Effects of Subliminal Messaging and Beyond Introduction The controversy that is subliminal messaging has continually been analyzed and studied for decades. The vastness of perspectives that can be found from experts around the globe is astonishing. The variety of so-called subliminal messages reaches from very subjective ad-reading analysis, to hidden text and images, to supposed satanic messages in rock music and layers of auditory messages in clothing and department stores and sold across the globe in ‘self-help’ tapes. The fact that these messages are present is undisputed, however their effectiveness is what is in question, and has been since it was first studied, scientifically or not. Can we, as consumers, be so easily manipulated by the select few? If so, how and to what extent are we manipulated? It is preposterous to believe that our thoughts are being controlled, but can our consumer habits be directed by the persuasive advertising community? Subliminal Messaging Definition Since the concept first originated, the definition of subliminal perception has been altered and/or rejected countless times. One must first not only define the term ‘subliminal’ but also accept it’s existence. Generally, subliminal refers to the ‘subconscious’ or below some threshold called the limen of consciousness (therefore subliminal stimulus would be that without a person’s awareness).
