Aurora
An aurora (plural aurorae/auroras) is an electro-static phenomenon, characterised by a bright glow and caused by the collision of charged particles in the magnetosphere with atoms in the Earth’s upper atmosphere.


Ultimately, the source lies in the solar wind, a fast-moving stream of particles constantly flowing from the Sun that carries the Sun’s magnetic field out into space. The solar wind, typically moving at 250 miles (400 kilometers) per second, flows past Earth’s magnetic field and molds it into an elongated bubble or cavity, compressing its sunward side and stretching its night side far beyond the Moon’s orbit. Under certain conditions, the solar wind’s magnetic field can merge with Earth’s, creating electrical currents that drive protons and electrons into the polar atmosphere. Powerful events occurring on the Sun can drive enormous changes in the solar wind, increasing both its speed and density and enhancing its effect on Earth.

An aurora is usually observed in the night sky, particularly in the polar zone. For this latter reason, some scientists call it a “polar aurora” (or “aurora polaris”).

Aurora Coloured light in the night sky near the Earth’s magnetic poles, called aurora borealis (‘northern lights’) in the northern hemisphere and aurora australis (‘southern lights’) in the southern hemisphere.






Northern lights is the name of a light phenomenon often seen in the northern regions. The lights have been around since Earth formed an atmosphere The scientific name for the phenomenon is “Aurora Borealis”, aurora for short.








The southern lights or aurora australis, most commonly seen in southern New Zealand. It shows a typical red and green aurora, the nearly vertical rays tracing the earth’s magnetic field lines.

The Pros and Cons of School Uniform
School uniforms are dress codes that are determined by the teaching institutions and students has to follow the designed code obediently everyday. Many people believe that school uniforms should be applied but the others don't.

Uniforms have various advantages for both the family and the child. A united school apparel can relief a financial stress of the backs of many families. As kids tend to compete and imitate each other, the race of following new trends in fashion or, providing different attire for every school day is considered a financial burden, not every family can afford it.

Additionally, a uniform creates a sense of equality between all pupils. Young kids tend to judge others according to their look and what they wear. Uniting their school attire will draw their attention to other criteria and, the only advantage of one student over another would be personality, academic achievement or being good at sports.



On the other hand, as repetition can lead to boredom, children can get frustrated of wearing same thing to school every day. Also, prevent their first steps of individuality by taking away their right to choose what to wear on their own free well.

In conclusion, I believe uniforms aren’t meant to suppress the creativity or freedom of children. It helps redirecting kids’ creativity towards more important things than outer look, and waive financial burden of their families.

Narrative story : The Stupid King !

       Once upon a time, there was a king who loved to wear new clothes. He spent much time just looking at herself in the mirror, and always wanted to wear new clothes in the morning, noon and night! One day, came two fraudsters posing as a great dress maker. They claimed that they are good at weaving and making clothes with very good quality. fabric that they used to made clothes will not be visible, except by smart people.

       When the king heard this, he was very interested. "That's great, I can know who is stupid and anyone who is smart in this kingdom." He thought. The king immediately ordered the two men to make new clothes for himself, using a special fabric. They were given a special room in the palace, along with threads of gold which they have requested. Both fraudsters hide the threads of gold which they receive, and then pretend to work hard to make a dress.

       A few days later, the impatient king sent his ministers to look at clothes that are being made it special. When the minister visited the deceiver in disguise, he was confused. "I do not see anything here" he thought. But the minister did not want to admit it because they do not want to be stupid. So he praised both the swindler and said that the clothes they make are very beautiful. After the minister out of the room, both burst out laughing trickster.

Soon the king came to see. She tried to see the whole room, but he did not see anything. However, because they didn’t want to be stupid, the king pretended to see the special clothes and said, "Clothes are very beautiful, I can not wait to wear it"

       The next day is the day that the king will wear his new shirt at the parade around the city. Both fraudsters masquerading has said goodbye and left the grounds will make clothes for the king of the other kingdoms. Of course, they do not forget to bring the threads of gold which they had hidden, and gold money wages to make clothes.

       When the king wearing his new clothes, he still could not see the clothes, and he felt cold. But because they do not want to say stupid, the king was circling in front of the mirror and admiring his new clothes, although he did not see anything. All the royal officials also said that the new clothes were beautiful, because they also do not want to be stupid.

      All people should hear that the king would have been wearing new clothes that day's specials. When the king appeared, all surprised. But they have also heard that a special new outfit that can only be seen by people who are smart, and because they do not want to be stupid, they cry out praising the king.

       Suddenly the sound of children screaming, "but he did not wear clothes, the king is naked!" All was silent. King realized that the little boy telling the truth, and hurriedly he walked back to the palace.
