5 Fun ACT Test Facts For a Study Break

5 Fun ACT Test Facts For a Study Break SAT / ACT Prep Online Guides and Tips As stressful as the ACT can be, you shouldn’t take it too seriously. It’s an important test, sure, but just a test all the same. Here are fiveweird facts about the ACT to help you feel less overwhelmed by studying. Fact #1: Harvey Mudd was the last college to start acceptingthe ACT Although the SAT was the original college admission test, most schools have been treating the ACT equally for decades. A major exception wasengineering college Harvey Mudd, which didn't allow applicants to submit ACT scores until 2007- making it the very last school to do so. Fact#2: The ACT was originally intended to be a placement test as well as an admissions test When it was first designed, the ACT was meant to compete with the SAT by testing knowledge rather than potential. Given that the testwas meant to showwhat students actually knew, founderE. F. Lindquistwanted the ACT tobe used for placement as well as admissions. Alas, that use never really caught on (except with some community colleges). But the ACT's curriculum-based testing approach has influenced the College Board's many changes to the SAT, especially next year's major overhaul. Fact #3: The ACT is now more popular than the SAT In the past few years, the ACT’s popularity has actually surpassed the SAT’s. 1.85 million students from the class of 2014 took the ACT and 1.67 million took the SAT. If you have questions about the differences between the two tests, check out our comparison guides for the current SAT and the ACT and the new SAT and the ACT. Fact #4: Cheating on the ACT can get you arrested In 20, a group of college students who were caught taking the ACT for others were brought up on criminal charges in New York (although ultimately none of them went to jail). Another case of ACT cheating involvedteachers at one Kentucky schoolhelpingtheir students with difficult questions. The New York cheating scandal is the reason ACT admission tickets now include a photo. Fact #5: Colorado and Illinois were the first states to require all juniors to take the ACT If you live in the Midwestor Southeast, there’s a good chance you’ll be required to take the ACT in your high school. Although 16 states now require the test, the practice started back in 2001 with just two: Colorado and Illinois. Ironically, the ACT is no longer required of all Illinois juniors: the state decided last year to allow districts to opt out of the testing.

Yttrium Facts - Chemical Physical Properties

Yttrium Facts - Chemical Physical Properties Yttrium oxides are a component of the phosphors used to produce the red color in television picture tubes. The oxides have potential use in ceramics and glass. Yttrium oxides have high melting points and impart shock resistance and low expansion to glass. Yttrium iron garnets are used to filter microwaves and as transmitters and transducers of acoustic energy. Yttrium aluminum garnets, with a hardness of 8.5, are used to simulate diamond gemstones. Small quantities of yttrium may be added to reduce the grain size in chromium, molybdenum, zirconium, and titanium, and to increase the strength of aluminum and magnesium alloys. Yttrium is used as a deoxidizer for vanadium and other nonferrous metals. It is used as a catalyst in the polymerization of ethylene. Basic Facts About Yttrium Atomic Number: 39 Symbol: Y Atomic Weight: 88.90585 Discovery: Johann Gadolin 1794 (Finland) Electron Configuration: [Kr] 5s1 4d1 Word Origin: Named for Ytterby, a village in Sweden near Vauxholm. Ytterby is the site of a quarry which yielded many minerals containing rare earths and other elements (erbium, terbium, and ytterbium). Isotopes: Natural yttrium is composed of yttrium-89 only. 19 unstable isotopes are also known. Properties: Yttrium has a metallic silver luster. It is relatively stable in the air except when finely divided. Yttrium turnings will ignite in air if their temperature exceeds 400Â °C.

Memphis Design-Michele De Lucchi and Ettore Sottsass Essay

Memphis Design-Michele De Lucchi and Ettore Sottsass - Essay Example The paper "Memphis Design-Michele De Lucchi and Ettore Sottsass" discovers postmodernism and Memphis design group. With inspirations derived from earlier movements such as Pop Art and Art Deco, the colors were used in both a graphic and dynamic way. The use of history in the Memphis post modernist furniture is particularly evidenced by the way their colorful designs that were reminiscent of the 1950s and 1960s ‘op’ art movement. The use of history and drawing of inspirations from the past in post modernism was particularly meant to counter the modernist concepts of writing history or starting from scratch after all was lost during the war. The social and cultural changes in 1970 led to the reaction against modernism. Designers embraced popular consumerism and culture. The modernistic principle required all objects to functional. Radical designers started to define a new language for design and moved away from functional well-designed goods. Ettore sottsass and De Lucchi were particularly frustrated by the rigid attitudes of the international design community. The post modernist artists were inspired by cultural, emotional philosophical, ancient, and contemporary influences. Together with De Lucchi and other designers, he founded Memphis to explore a visual language for design based on the popular culture and kitsch. The group wanted to experiment with new designs and materials. Ettore wanted to discover new and unique ways of using materials to bring a wealth of artistic influences.

Media and the phenomenon of child killers Essay

Media and the phenomenon of child killers - Essay Example The gruesome sight of the body of four-year-old Horace Millen at the beach at Dorchester Bay initially led those who had seen it to believe that it was the work of a grown man or an adult. Little did they know that such savagery was the handiwork of a boy barely out of childhood. He was sent to a reform school prior to the incident for beating up younger children and using an astounding degree of unnecessary physical force.When people began speculating about the kind of background this child might have that led him to commit such unspeakable acts of atrocity, one thing that came up was his penchant for dime novels.Sordid tales of killing and violence leapt from the pages of these dime novels, and many believe that these tales emboldened him to commit the crimes himself.From the first example of Jesse Pomeroy, recent history has had its share of child killers and child criminals. There is the Heath High School shooting where Michael Carneal, just fourteen years old, opened fire at a g roup of students praying and killed three female students while wounding five others. Two years later, in 1999, the Columbine massacre took place wherein two teenagers, Eric Harris and Dylan Klebold, killed twelve students and a teacher, and wounded twenty four others, before turning the guns on themselves and committing suicide.Just this year, on April 16, 2007, in Blacksburg, Virginia, a Korean-American by the name of Cho Seung -Hui went on a killing spree that was to become the deadliest shooting rampage in America. After the smoke had cleared, the death count was 32 bodies. Much speculation has taken place as to what might have caused children to behave in this manner. Of course, several factors came into play: mental illness, family background, a history of child abuse, teen-age social stratifications (particularly in the case of Columbine and Virginia Tech) and a host of other factors that contribute to maladjustment. However, ever since the case of Jesse Pomeroy, an accusing finger has been particularly directed towards the media. It has been said that the surfeit of violent images depicted in it that could have triggered psychological responses in the child-perpetrators. Indeed, there is no dearth of cases and examples to prove that there is a causation between media violence and violent behavior. In an article entitled "The Impact of Mass Media Violence on US Homicides", Phillips (1983, p. 560) presented "what may be the first systematic evidence suggesting that some homicides are indeed triggered by a type of mass media violence." Just a year before, he came out with another paper, with the following findings: Violent, fictional television stories trigger imitative deaths and near fatal accidents in the United States. In 19877, suicides, motor vehicle deaths and non-fatal accidents all rose immediately following soap opera suicide stories. The U.S. female suicides increased proportionally more than male suicides. Single-vehicle crashes increased more than multiple vehicle suicides.1 Several years after Phillips came out with his seminal studies, new researchers came out with evidence to support his conclusions. Cornstock2 found "a very solid relationship between viewing anti-social portrayals or violent episodes and behaving anti-socially." Even more compelling, Huesman and Erron3 published a 20-year follow up of 400 children and discovered that heavy exposure to television violence at eight years old was associated with violent crime and spouse or child abuse at age 30 and this is true for all socio-economic levels and for all levels of intelligence. More careful than her predecessors but presenting evidence equally noteworthy, Sheenan4 found that the question of the young being more vulnerable to the effect of media is a complex and difficult one to interpret precisely.

Natural Family Planning :: essays research papers fc

The Natural Failure of Planning   Ã‚  Ã‚  Ã‚  Ã‚  Are modern forms of contraception naturally and morally wrong? Pope Paul VI and his Humanae Vitae declare that technological methods of birth control are immoral and should not be practiced by Catholics. However, as our modern society illustrates everyday, this opinion is inappropriate for not only the faithful of the Roman Catholic Church, but also for non-Catholics. According to Munich Archbishop Cardinal Julius Doepfner, â€Å"Contraception is not intrinsically evil† (The Politics of Sex and Religion). There is a fine line the Catholic church draws between â€Å"natural† methods of family planning and the â€Å"immoral† methods of modern technology. After close review of Catholic doctrines, it is clear that this line does not exist. The intentions behind the actions are what matters. Therefore the encyclical of Paul VI , while maintaining good intentions, cannot give Catholics and non-Catholics alike complete guidance in complete humanness when it comes to contraception.   Ã‚  Ã‚  Ã‚  Ã‚  The major problem for the married believers in the Catholic faith is that Human Vitae neglects their ability to make moral decisions. Paul VI claims that contraception limits a person’s human totality and integrity. However, the reality is that the Church is limiting this principle of human existence by assuming the common man is incapable of making the correct moral choice. For example Paul VI states , â€Å"†¦how wide and easy a road would thus be opened up towards conjugal infidelity and the general lowering of morality.† (Human Vitae 8). It is absurd to believe that all moral problems in our society can be attributed to the introduction of birth control methods. Man, in his complete integrity and totality, is capable of judging moral from immoral regardless of the technological devices he is surrounded by. If all parts of a human are in harmony, means of contraception cannot invade this person’s complete humanness.   Ã‚  Ã‚  Ã‚  Ã‚  Scientific research shows that almost all practicing Catholics today believe that modern means of contraception does not interfere with their beliefs and morals. According to one study, â€Å"Even among married Catholic women who attend church every week, less than 4% use church-approved family planning methods-about the same as the total population.† (Catholics for Contraception). This illustrates the fact that people of faith have made their own interpretations of God’s desires and find no difference between natural family planning and modern methods of contraception. Weekly patrons of the church know the moral teachings of the Church and the consequences, yet the facts show that all believers have not come to a consensus.

Electrons The Building Blocks Of Science Environmental Sciences Essay

Electrons have been the cardinal component to many mystifiers in life ; if it were non for several doctors and their parts to the finds of different belongingss of the negatron, the scientific disciplines ( chemical science, biological science, and natural philosophies ) would non be the same. The earliest recorded experience with electricity ( apart from buoy uping ) was with the ancient Greeks who noticed that gold attracted little objects when rubbed with pelt. The history of negatrons has been a compile of little finds made by many doctors, yet the most noteworthy finds were made by Benjamin Franklin, Eugen Goldstein, J.J. Thompson, Neils Bohr, Gilbert Lewis, Wolfgang Pauli, and Thomas Young. Benjamin Franklin work with electricity led him to coin footings and suggest several theories affecting batteries, music directors, capacitors, charges, and discharges. He came up with the thought of â€Å" positive † and â€Å" negative † electricity holding â€Å" plus † and â€Å" subtraction † charges. He falsely thought electric flow was from positive to negative ; now we know the opposite is true. Yet, the thought of positive and negative charges builds the foundations of circuits. Through Franklin, we learn that charge flows from the high electromotive force terminus of the power supply through carry oning wires to the resistances, where the energy of the charges is used to make work, or is dissipated as heat. The charge so flows back to the low electromotive force terminus of the power supply by more wires. Charges besides emit an electric field, utilizing a voltmeter to find the strength and way of these Fieldss by mapping the electric potency of the field. From the possible field, the electric field can be determined. The electric field lines can be found by get downing at the positive electrode and following a way to the negative electrode so that the electric field lines ever cross the possible field lines at right angles. Cathode rays played a major portion of the find of subatomic atoms and their behaviour. In 1876, Eugen GoldsteinA discovered that discharge tubings with a pierced cathode besides emit a freshness at the cathode terminal, which was subsequently recognized as negatrons traveling from the negatively-charged cathode toward the positively-chargedA anode. He besides concluded that there was another beam that travels in the opposite way. They are composed of positive ions whose individuality depends on the residuary gas inside the tubing, which subsequently became portion of the footing forA mass spectroscopy. With the cathode beam, he besides discovered magnetic Fieldss exert a â€Å" crabwise † force on traveling charged atoms. That is, if a charged atom travels through a magnetic field, the field will exercise a force directed at right angles to the atom ‘s gesture. Charged atoms can be made to go in a circle by puting up a magnetic field. In 1896, J.J. Thomson and his colleaguesA performed experiments bespeaking that cathode beams truly were atoms, alternatively of moving ridges, atoms or molecules that many believed before. Thomson made a reasonably accurate estimation of both the chargeA eA and the massA m, happening that cathode beam atoms had around a one thousandth of the mass of hydrogen.A The e/m device in his lab generates a seeable beam of negatrons and directs the beam through a unvarying magnetic field. When high-velocity negatrons strike the atoms in the gas, the atoms give off a green colored visible radiation. This makes the beam seeable. Most negatrons in the beam do n't clash with any atoms, since the gas is really thin. But those that do demo the way the negatrons are taking. Electric currents create magnetic Fieldss. At the centre of the spirals, the B-field is approximately unvarying and directed analogues with the land. This causes the negatrons to turn. The radius of the circle will depend on the strength of the magnetic field B, the velocity of the atom V, and the atom ‘s mass. The strength of the B-field depends on the current in the spirals. By mensurating the radius of the beam ‘s round way, he found the mass of the negatron. A unit of ammunition glass vacuity tubing with a glowing round beam inside The edifice block of chemical science and bonding was explored as Niels Bohr explained a simplified version of the atom, now named Bohr Atom. It is non right, but it provides a utile manner to visualise spectra and their creative activity. A â€Å" cloud † of negatrons in â€Å" orbits † surrounds the highly bantam karyon. Atoms are characterized by a karyon: the cardinal, bantam, monolithic portion. Its charge is impersonal or none. The karyon is made up of positively charged protons and impersonal neutrons. Electron: the negatively charged atom that orbits the karyon of an atom.Photon: the smallest possible sum of E & A ; M energy of a peculiar wavelength. An atom consists of a little, heavy karyon surrounded by negatrons.He hypothesized that negatrons were in quantal energy provinces. In the atom the negatrons are normally in the â€Å" land province † , n = 1. This is the lowest energy province of the atom. If an negatron is excited ( such as by an electric c urrent in a neon tubing ) it will absorb a specific photon and move to a higher energy orbits or â€Å" aroused provinces † .Because energy in an atom is â€Å" quantal † , the negatron can merely travel to specific energy provinces ; most energy provinces are out. Each set of orbits for every component and compound is different from every other set. When an negatron in an component in a low-pressure gas province absorbs a photon of visible radiation it becomes excited, and it moves to a higher electronic energy province. Then it will spontaneously fall back to the lowest energy province possible, breathing the exact same wavelength photon it absorbed. Because merely distinct energy provinces are allowed, merely a few photons will excite the negatrons. Disintegrating back to the lowest energy province produces merely a few photons. Three homocentric circles about a karyon, with an negatron traveling from the 2nd to the first circle and let go ofing a photon This is an emanation spectrum. Since the wavelength is precise, the exact energies of the orbits are known from: Tocopherol = hc/l. After its excited the negatron will drop to a lower energy province by breathing a photon of precisely the same wavelength it absorbed. When it does that we can see the photon as a specific coloured line in the spectrum. EMISSION SPECTRA is the easiest spectra to analyze in the lab, but it is seldom found in stars. Some interstellar clouds and active galaxies have emanation spectra. EVERY ELEMENT AND EVERY MOLECULE HAS A DIFFERENT SPECTRA! The spectra from an unknown sample can be used to find all the elements and molecules within the sample. When there are many elements, near together, the energy degrees of the person atoms are spread out into energy sets. This consequences in a uninterrupted spectrum. Yet, Bohr ‘s theoretical account failed to account for the comparative strengths of the spectral lines and it was unsuccessful in explicating the s pectra of more complex atoms. In 1924, Austrian physicistA Wolfgang PauliA observed that no more one negatron can busy the same quantum energy province. Therefore, the Pauli exclusion rule provinces that no two negatrons in an atom may busy the same energy province. Each negatron has an single â€Å" orbit † . These orbits are ruled by quantum mechanics. Chemical bonds between atoms were explained byA Gilbert Newton Lewis, who in 1916 proposed that aA covalent bondA between two atoms is maintained by a brace of negatrons shared between them.A Adhering between elements As with all atoms, negatrons can move as waves.It is impossible to detect both belongingss at the same clip in the same moving ridge. Einstein ‘s photoelectric experiment besides proved this dichotomy. Thomas Young ‘s dual slit experiment shows this wave-particle dichotomy, besides turn outing that visible radiation was a moving ridge. This experiment had profound deductions, finding most of 19th century natural philosophies and ensuing in several efforts to detect the quintessence, or the medium of light extension. Though the experiment is most noteworthy with visible radiation, the fact is that this kind of experiment can be performed with any type of moving ridge, such as H2O. Inactive Fieldss = imaging ( MRI, etc ) The history of negatrons has been a huge series of different doctors happening little spots of information about this unknown atom. If it were non for these finds of the belongingss of the negatron, we would non cognize how electric Fieldss work, the utilizations of a cathode beam, how elements bonded, the capablenesss of energy that come from atoms, and practical applications such as imaging. It would be good to research more on negatrons and be portion of the find as other doctors have done. Plants Cited Page Anderson, David L.A The Discovery of the Electron. New York: Arno, 1981.
