Hey kids. Here comes another question.

Everytime when we touch an ice, it feels sticky. Why?
Is it because…
A. The ice melts very fast
B. The ice has glue on it (You must be joking ;))
C. The ice is cold, our hands is hot
D. Our hands is sticky

The answer is C. The ice is cold, our hands is hot

Now, let me explains why…

The ice allows use to leave it alone, but is just that we ‘like’ to stick with the ice.

Sounds funny?!!!

Well to the ice, our body temparature is very hot. Remember ice melting point is 32°F or 0°C. While our temparature is 98.6°F or 37°C. The moment our hands touch an ice, heat energy from our fingers will be absorbed by the ice. The surface that our fingers touch will melt a little.

Very quicky the heat energy will travel into the ice. The water(which was melted when our fingers touch the ice) on the surface of ice quicky become frozen again. The process of melting and frozen on the surface of ice creates the feeling of stickyness.

Unless we hold on to an ice without letting it go, allowing the heat energy from our hands keep flowing into the ice. This will make ice melts slowly and the sticky feeling will dissapear.

Hey, kids… What do u think?

Human greatest discovery are…
A. Food
B. Fire
C. Water

E. All of the above

Think for 10 seconds and tell me what is your answer.

(Drumming sound….)The moment of truth…

The answer is… B. Fire

Camp Fire

According to Dictionary.com , discovery is an act or an instance of discovering.

Until now, scholars agree that humans greatest discovery is FIRE. Ever since humans learnt how to use fire to get rid of wild beast and they don’t have to live in the cave anymore.

So, humans started to live on flat ground, they started to build houses on their own. Besides, fire helps to cook food, fire also helps to make a lot tool for farming, hunting, cutting.

What is a supertankers ?

Don’t confuse them with the tanks in the military. They travel on waters.

Found this picture from www.auuuu.com

In fact they are large crude oil tankers which carry crude oil ranging from 150 to 300 thousand tons. With their full power on, an oil tanker with very huge inertia needs a long time to get to its maximum speed.

So kids, you might ask: “How do they stop then ?”

Well, kids. Even with engine set into reverse condition (propeller in reverse rotation), the oil tankers still need to travel about 10km before they can come to a stop. Remember ship don’t have brake. They can’t just stop.

With such a big internia on the oil tanker, they just can turn left or right as easy in driving the cars. So for every turn, the captain needs to set the direction of the propeller correctly well before the tanker make a turn.

Please help to save more turtles

Normally, a mature sea turtle can be six or seven feet (2 m) in length, and three to five feet (1 to 1.5 m) in width, weighing up to 1300 pounds (650 kg).

Although, a sea turtle can swim very easying in the sea. It is very hard for them to move around the beach. And they look clumsy. If you seen a sea turtle before, you know what I mean.

Movement of sea turtles is made tougher with their short neck and short limbs or legs.

So, once a turtle is overturn. It just can’t turn over again.

Kids…Please helps those turtles…It means a lot to them.
