Project Base Learning in the classroom Essay Example for Free

Project Base Learning in the classroom Essay Project based learning in classroom is a great departure from that of the conventional classroom learning method. The conventional learning is teacher centric and the students learn directly from their teacher. On the other hand, the project based learning is student centric while the teacher has only the role of a facilitator. Today’s world is more advanced in technology hence more complex. There are a lot of opportunities as well as various problems. Only those who can successfully handle such complex tasks can succeed in the modern life. The student needs to be prepared to face such things in their future life. And the project based learning in the classroom itself gives them a glimpse of challenges lying ahead and types of life surviving skills that needed to face them. In this method, the students are given challenging tasks, individually or in a group, which they need to carry out, using the concepts and principles they learned from the text books and their own common sense and creative thinking. Most of the tasks given to the students are related to real life situations. The basic idea behind using such real life situations is that it will make the student competent enough to construct solutions for such situations in the real life as when they arise. Project based learning method allows the students to decide themselves the course of actions in order to achieve the objective of the task or solve the given problem. They ask themselves the questions that need to be answered to produce the required answers. They themselves find out the answers and the ways to meet the set objectives. Their inherent qualities like leadership skills, problem solving skills and communication skills etc are forced to develop during this process. They also learn to think in a group which is essential in modern work culture. Unlike the passive role they played in the teacher centric learning method, the students are leaning things by actually doing it and experiencing the thrill as well as the difficulties of such learning. They get a chance to apply the knowledge they acquired from the text books on to the real life situations. The students direct themselves and this instills in them a sense of responsibility and their motivational levels will go up. The utilization of technology such as computer and internet etc give them a real clue about their immense utility. They get to experience the pride that is associated with the achievement of goals and they are ready for more. The teacher, who is also the facilitator, finally assesses the findings or suggestions submitted by the students and give his feedback. The feedback is very much important for the students and will help them make good the shortcoming and move forward. This way they horn their skills in every area of leaning and by the time they finish the schooling, they are ready to take on the numerous challenges that the life throws at them.

Capital Punishment in America Capital punishment should be viewed as the stripping away of humanity from a person. The death penalty itself should be "executed" because of racial inequities, the concept of murder, the possibility of error, lack of deterrence, the cost, and an overwhelmed legal system. "The goal of capital punishment is revenge" (Introduction 1). Capital punishment is simply an outlet for the bloodlust of the American people (Introduction 1). The death penalty is very discriminatory when it comes to racial issues. "The death penalty is fraught with abuses and the potential for abuse" (Moral Arguments 1). Capital punishment is largely "divided along racial lines" (Moral Arguments 1). "A 1990 report released by the Federal Government’s General Accounting Office found a ‘pattern of evidence indicating racial disparities in the charging, sentencing, and imposition of the death penalty after the Furman decision’" (Moral Arguments 1). In the 1970’s, Professor David Baldus examined sentencing patterns in Georgia. He reviewed over two-thousand five hundred homicide cases in Georgia and controlled for two-hundred and thirty non-racial factors. His conclusion was that "a person accused of killing a white was 4.3 times more likely to be sentenced to death than a person accused of killing a black" (Moral Arguments 1). Imagine the statistics when one adds the rest of the states in our country. Capital punishment is murder. It really doesn’t matter how you look at it. The end result is still the same. "What is the difference between the state killing and an individual killing" (Moral Arguments 1). It adds up to be the same end result. It is "one more dead body, one more set of grieving parents, and one more cemetery slot. When we execute someone, we are sending a profound message of cynicism" about the value of human life (Moral Arguments 2). "Every time we execute someone," we are sinking to the same level as the killer (Moral Arguments 2). "The American people have blood on their hands, and it will stay there until we finally remove this barbaric practice from our nation" (Moral Arguments 2). One of the most apparent reasons the d... ... The death penalty is based upon revenge against the murderer. All it adds up to at the end of the day is another corpse to bury.

Evolution of the Universe Essay

The evolution of earth will always remain a mystery. However, there is many scenarios and evidence to help understand the evolution of earth, its sun, planets, and the moon. The paper will derscribe how the earth and its atmosphere evolved with the help of other bodies. Which includes a discription of the formation of the bodies that plays a role in the evolution of earth. Also, a discription of the earth, sun, moon, planets, and other bodies motions according to Copernicus, Kepler, and Gallileo discoveries. Evolution: Earth and Its Atmosphere Plate tectonics are the ultimate process that controls the changes on Earth. Dynamic activity like volcanism, meteorite impacts, mountain building, and erosion, is how our Earth has come to its current state, while the continuing motion of the Earth is what’s driving the resurfacing of the Earth resulting in faulting, basin formation, and volcanism. The combination of gravity and the Earth’s internal heat is the driving force for this continuous motion. Earth’s internal heat comes from consistent decay of radioactive elements, crystallization of the inner core, and the heat left-over from planet formation. Recent discoveries suggest that features of current Earth come from the planetary melting and planetary accumulation which involves the differentiation of objects. Mars and the Moon underwent global differentiation which allowed the separation of the core from the mantle and formed large parts of the Earth’s still-existing crust. The atmosphere and oceans first appeared about 4. 5 billion years ago, soon after the Earth and Moon completed their formational phases (Mirali & Skinner, 2009). Oxygen was nearly absent in the atmosphere of the early Earth. The Great Oxygenation Event (GOE), or Great Oxidation, was the biologically induced appearance of free oxygen (O2) in Earth’s atmosphere. Cyanobacteria; a large photosynthetic bacterium, appears approximately 200 million years before the GOE and began to produce oxygen by photosynthesis (Carlson & Boyet, 2008). Cyanbacteria is known to be responsible for the initial rise of atmospheric oxygen during this time. Before the GOE, any free oxygen was chemically captured by dissolved iron or organic matter. After the GOE, any excess free oxygen began to accumulate in the atmosphere. Free oxygen is toxic to anaerobic organisms and the rising concentrations may have been the reason that most of the Earth’s anaerobic inhabitants were wiped out. Oxygen is dominantly locked in minerals in the crust and Earth’s interior and would remain as such if it weren’t for photo synthesizers. Methane and nitrous oxide have been increasing in recent years and a consequence of agricultural activities, and human-induced global warming (Kasing & Siefert, 2002). Thus, microorganisms have led to the basic composition of Earth’s atmosphere since the origin of life. Formation of the Bodies: Motions Role About five billion years ago the galaxy had a supernova explosion causing large elements of debris pushing it through gasses called hydrogen into interstellar particles and dust. By this process of mixture under its own gravity at the center, it compressed together and formed a star of gasses that we see today. This star now became born which is now the sun, which around it a swirl of material compressed as forces for the heat. This process gave rise to our sister planets and throughout the universe. The sun started to grow larger and its energy source also started to ignite its source outward into nuclear fire balls. Within millions of years disks and components started to freeze over into small grains of dust. From this process what was found was silicon, iron, aluminum, magnesium with oxygen that was displayed as clumps and large chunks of rock and boulder. They were so large that they broke apart from their own gravity and disbursed throughout the universe. Planetesimals planets started to grow, from this they were colliding with other bodies, now starting to grow into larger lanets with their form of mass and energy behind them giving them the power to move. In this time in history the sun was only about 2/3’s of the source of power that we have today, meaning the sun is more power today than ever, because of time and energy and mass letting it grow. The process of the large forms of mass rocks grew in time from there silicon, iron, aluminum, magnesium and oxygen with the help of the sun that now grew the planets that we know of today. As all the planets grew in time and formed to what we know them as, they all rotate in a clock ward motion. As the planets move together in the same motion they are creating energy within their centrifugal force, which keeps them in motion and growing with the support of the sun’s energy. Scientist’s Discoveries: Earth, Sun, Moon, Planets, Bodies The motions of the bodies in the universe were explained by several scientists between the 1490’s and the 1700’s. Initially, there was a widely held belief that the Earth was stationary and all of the other bodies revolved around it; this is called a geocentric model (Merali & Skinner, 2009). In the 1490’s however, a scientist named Copernicus began to address the fact that a geocentric model did not explain the movement of the planets. His discoveries began to show that a heliocentric system (sun is stationary, central and the planets revolve around it) was more likely based on noticing that planets temporarily reversed direction (Merali & Skinner, 2009). He surmised that the temporary reversal was because of the differences in time that it takes the Earth to orbit the Sun, versus the time it took for other bodies to orbit the sun (Merali & Skinner, 2009). Copernicus also determined that a body with a larger temporary reversal of direction was closer to earth and a smaller reversal was further away which could be tested by astronomical measurements (Merali & Skinner, 2009). Finally, Copernicus resurrected an old theory that the Earth spins on an axis which explains the rising and setting of the sun (Merali & Skinner, 2009). Copernicus’ discoveries led other scientists to also prove the heliocentric model. In the late 1500’s, Kepler discovered three laws that would bolster Copernicus’ heliocentric model, but would also prove his ideas about the shape of orbits wrong (Merali & Skinner, 2009). First, the Law of Ellipses says that each planets orbit is an ellipse and the sun is one focus (Merali & Skinner, 2009). Next, the Law of Equal Areas determines that the planet’s orbital speeds are not the same and therefore the closer they are to the sun the faster they orbit and alternately, the further from the sun, the slower the orbit (Merali & Skinner, 2009). Lastly, the Law of Orbital Harmony is a mathematical equation that determined that â€Å"the square of the orbital period in years is proportional to the cube of the planet’s average distance from the sun. † (Merali & Skinner, para. 11, 2009). Therefore, the Earth takes 356. 24219 days, or 1 year, to orbit the sun (Merali & Skinner, 2009). Even with these three valuable laws, it was Galileo and Newton who pulled the heliocentric model together. In the late 1600’s Galileo used a telescope to find four moons orbiting Jupiter which proved that Earth could not be at the center of orbital motion (Merali & Skinner, 2009). Galileo also determined that Venus had phases which could only be explained if Venus and Earth orbited the sun (Merali & Skinner, 2009). Finally, Galileo postulated that forces move bodies. Additionally, those bodies will only change direction or stop if influenced by another force and that force works equally on all bodies despite differences in mass (Merali & Skinner, 2009). It was this last concept that inspired Isaac Newton in the same period. Newton determined that if an apple was pulled to the Earth by gravity, then the moon would also be affected by gravity thus discovery that gravity influences all bodies on Earth and in the universe (Merali & Skinner, 2009). Conclusion Modern science will continue to have plenty of unanswered questions. The evolution of earth begins with the plate tectonics process that includes corollaries of mantle convention, contienental drift, seafloor spereading and explains the pattern of volcanoes, earthquakes, and mountain building. The atmosphere and oceans evolved 4. 5 years ago after the earth and moon completed their formational phases. With the help of Great Oxygenation Event (GOE), photosynthesis, and Cyanobacteria the earth produced oxygen. The formation of bodies occurred five billion years ago when the supernova explosion caused the birth of the sun and other planets. Issac Newton, Copernicus, Galileo, and Kepler were very important scientist from the 1490s and the 1700s who made many discoveries about the earth, sun, planets, and other bodies motions.

Obesity And Its Effects On Children - 1558 Words

Obesity is one of the several major public health issues that researchers attempt to find interventions for. Prevalence of obesity has been increasing throughout the years, especially in children. If prevalence and incidence of obesity continues to increase in children, long term illnesses start producing, which can hinder an individual’s life span. In addition to chronic illnesses being produced, obesity can also hinder the social and psychological wellbeing. As children are growing with obesity, they are experiencing the negative effects of their social life and psychological self, which can create chronic illnesses and prevent them from growing as an individual. There have been many interventions targeting obesity and its negative†¦show more content†¦Liquor stores do not provide all the essential food required to have a healthy diet, so Hispanic immigrants are forced to purchase the only food nearest to them. Even though the study was conducted on the Hispanic immigrant community, the generalizability of other cultures are unknown, but other cultures who reside with other Hispanic immigrant communities could possibly have the same environmental and social factors that cause obesity. This study also explains the parent’s perception of their children’s weight, which majority of parents said their children do not have the weight for obesity, when in reality, they are obese. The parent’s weight were also taken and results showed they have obesity as well. There must be a correlation between the obesity of the children and their parents, so this problem can be intervened with a program educating the parents about t he signs of obesity and how to maintain health. If parents learn about obesity and maintaining health, then they can implement that in their own lives in addition to supervising what their children eat and how much physical activity they engage in a day.
