How to prepare exam

I prepare for the exam by studying very hard. I have to work harder during my exam. I need to do lots of exercises and work. I must not go away from home before the exam. I must study my BM, English, science and work hard. I need to do harder in my studies. I need to have more ideas during composition. I must have every subject lots of As.

Poem to my lovely father

A - adorable Z - zest M - magical A - angry N - nice My father is adorable, He is full of zest. He is very magical. Sometimes he is angry, But at other times he is nice.

My first poem

Poem about me ZOEY ZEFFREY AZMAN Z - zest O - optimized E - empty Y - yolk Z - zest E - entertained F - friendly F - fun R - reserved E - eager Y - young The life full of zest, Trying to be optimized. Sometimes our hearts are empty, But some are full of yolk. The life is full of zest, Loved to be entertained. Surrounding the friendly, And having lots of fun. People who are reserved, They're very eager. I am a young child, Who cannot withstand.

New School - Stella Marris

Dear Bloger

This is my 3rd  months in a new school.  After 5 years in Sayfol International School then my Dad decided to move me to a private school belong to catholic church and following Malaysian subjects.  This school is quite small and compact. Seem like we know each other quite fast.

The students mainly Malaysian come different races and Chinese is a majority in this school.  The first month is quite though for me but slowly adapting well with a new stuff and a new set of teachers and friends .  Well, after a couple of months here, I managed to find a new friends but still missing my old friends which always in my heart.  Luckily Facebook has been is a good forum for me to keep in touch with them.

My favourite teacher are Mr Teh who is teaching me maths and Pn Effa, my Bahasa Malaysia teacher.  Mr Teh did allow me to do maths up to my level and currently just completed primary 6 book and he will give me a Secondary 1 maths work book for me to work on it.

Pn Effa also very helpful and without feeling bored..assisting me in Malay Language subject. Well hope I will do well for this coming 1st semester exam..and I will try hard to full fill my own dream and to achieve my goal to become a cardio-thoracic surgeon.

1st Semester Test and Monthly Test Results

Soon my first semester test is coming. I need to improve on my bahasa melayu. My monthly test results: Maths , 100 Science, 97 BM , 40 Average , 100 , 97, 40 : 237 / 3 - 79

New Planet Found

Astronomers reveal new type of planet

WASHINGTON: Using Hubble space telescope, an international team of astronomers have come up with a new class of planet, according to a report published online Tuesday in The Astrophysical Journal.

By analysing the previously discovered world GJ1214b, the team led by Harvard-Smithsonian Center for Astrophysics (CfA) astronomer Zachory Berta proved that it is a water world enshrouded by a thick, steamy atmosphere, according to China's Xinhua news agency. Our solar system contains three types of planets: rocky, terrestrial worlds (Mercury, Venus, Earth, and Mars), gas giants ( Jupiter and Saturn), and ice giants (Uranus and Neptune).

Planets orbiting distant stars come in an even wider variety, including lava worlds and "hot Jupiters". "GJ1214b is like no planet we know of. A huge fraction of its mass is made up of water," said Berta in a statement issued Tuesday. GJ1214b was discovered in 2009 by the ground-based MEarth Project. This super-Earth is about 2.7 times Earth's diameter and weighs almost seven times as much. It orbits a red-dwarf star every 38 hours at a distance of 1.3 million miles, giving it an estimated temperature of 230 degree Celsius.

In 2010, CfA scientist Jacob Bean and colleagues reported that they had measured the atmosphere of GJ1214b, finding it likely that the atmosphere was composed mainly of water. However, their observations could also be explained by the presence of a world- wide haze in GJ1214b's atmosphere. Berta and his co-authors used Hubble's WFC3 instrument to study GJ1214b when it crossed in front of its host star. During such a transit, the star's light is filtered through the planet's atmosphere, giving clues to the mix of gases.

Hazes are more transparent to infrared light than to visible light, so the Hubble observations help tell the difference between a steamy and a hazy atmosphere. They found the spectrum of GJ1214b to be featureless over a wide range of wave lengths, or colors. The atmospheric model most consistent with the Hubble data is a dense atmosphere of water vapor.

"The Hubble measurements really tip the balance in favor of a steamy atmosphere," said Berta. Since the planet's mass and size are known, astronomers can calculate the density, which works out to about two grams per cubic centimeter. Water has a density of one gram per cubic centimeter, while Earth's average density is 5.5 gram per cubic centimeter.

This suggests that GJ1214b has much more water than Earth, and much less rock. As a result, the internal structure of GJ1214b would be very different than our world. Theorists expect that GJ1214b formed farther out from its star, where water ice was plentiful, and migrated inward early in the system's history. In the process, it would have passed through the star's habitable zone.

GJ1214b is located in the direction of the constellation Ophiuchus, and just 40 light years from Earth. It's a prime candidate for study by the next-generation James Webb Space Telescope.
