Science Form Three: Chapter 1 - Respiration System

Adaptations of alveoli:

• The alveoli are one cell thick so that there is a short diffusion pathway for the gases and therefore faster diffusion rate.
• There are a large amount of alveoli to provide a larger surface area for gas exchange so more eefficient.
• The alveoli are surrounded by a vast network of capillaries, this increases the surface area of alveoli which are in contact with a capillary and allows for more efficient gas exchange.
• The alveoli walls are moistened, so gaseous exchange is more efficient through diffusion

Is This Your New Year Resolution?

Let me translate into English for those who can't read Chinese words.
The girl said, " I want to be a billionaire if every citizen in China give me 10 cents!"

My response to the girl:  "I will become bankrupt if every citizen in Malaysia think like you, asking me to give every 27 million Malaysians 10 cents. "

Come on, there is no free lunch in this world or short cut to success. Every success comes with a price. Start with study first to gain knowledge and skill before you become rich. The world second rich man and most successful investor, Warren Buffett finished reading all the books in his town library at the age of 9. At 80 years old, he still reading a lot of books. How about us?

Study --> Gain knowledge/skill --> Working --> Save Money --> Invest your saving --> Once you are successful, bless others as well.

PMR 2010 Report

Here is the PMR result of my small group of students. Some of them have followed my entire tuition class from Form 1 to Form 3. To my honest, all of you are wonderful student and I am proud to be your teacher. Thank you so much to be my student. And remember, say a big THANK YOU to your parents whose provide you transportation, time,  financially and emotional support.

Who said you can't score A in PMR

As long as you are willing to learn and eagers for success, you can do it!

Come on, prove again in SPM

You can score A in Physics, Chemistry, Additional Maths, Biology,

Once again.

Saya hanya menumpang gembira atas kejayaan kamu!

Merry X'mas 2010

Wish you all a blessed Merry Christmas!

Christmas is not about Santa Claus

Christmas is not about exchanging gift

Christmas is not about  snowing Christmas tree

For God so loved the world

Christ has come as a baby child in Bethlehem

His name is Jesus

He came to save us

Bringing us a gift of hope

To fill our hearts with love

This is God's eternal plan

And Christmas is the reason we celebrate.

Application of Centre of Gravity

Experts: High-decked bus unsuitable for highlands

PETALING JAYA: The bus involved in the horrific accident along the Cameron Highlands-Simpang Pulai road which killed 27 people was to be used only for city tours, not for long-distance travels, especially those involving hilly terrain, experts say. They said high-decked buses were unsuitable for travelling uphill as the centre of gravity was higher, making such vehicles very unstable. “The bus can become unstable when going uphill or when travelling at a higher speed. This is especially when drivers negotiate sharp bends,” he said.

He said all the passengers of the ill-fated bus were seated in the upper deck, adding: “This can result in instability and the centre of gravity is out.” The lower deck, he said, was designed as a conference room and was filled with the passengers’ luggage.Asked if such a vehicle was allowed to travel uphill, Dr Wong said: “A high-decked bus is more stable if its centre of gravity is lower.”

This is what you have learn from Form 2 Science lesson:

• the lower the centre of gravity, the higher the stability of the object.
• the wider the base area, the higher the stability of the object.

So, never ever board the double decker bus to Genting highlands or Cameron highlands!

Science knowledges really can save lives.

Singapore Government Hungers For Talents

I never expected that Singapore government acted so swift to lure our Malaysian talents. If you don't believe with your own eyes, kindly read the news below:

Singapore government had offered them a place in their university in a straight manner without hesitation and bureaucracy. In reality, they do not wait the outstanding students to finish their SPM to give scholarships. Their effective tool 'Asian Scholarship' has make a headway to lower secondary school by offering Form 2 outstanding students a chance to study in republic. Everything is sponsored by Singapore government. In contrast, our nation still plaguing with scholarship issue every year.
