Chapter 8: Will Krakatoa rock the world again?

Dear Gentlemen,

Especially for Class 1-5, I told you all about Krakatoa found in Indonesia and how it's explosiveness could be heard as far as Perth in Australia, also added that the amount of TNT/power that Krakatoa 13,000 times the power of the bomb that was dropped on Hiroshima! This eruption caused change in weather where average global temperatures following the eruption fell by as much as 1.2 C, as the huge quantities of sulphur dioxide pumped into the atmosphere resulted in clouds that reflected a greater amount of incoming light from the sun. Also of course, destruction to not only humans but also the physical environment.

Just last year, there were speculation of Krakatoa stirring and threatening to erupt again. See excerpts of the online UK daily news and the pictures of Krakatoa taken from there.

Ominous glow: In 1883, more than 36,0000 people died when Krakatoa erupted - today, thousands more farmers live near the volcano

Risk: The smoking time-bomb is located on the Sunda Strait, between Java and Sumatra

Ticking timebomb: Islanders thought they had avoided another disaster after things went quiet in 2008

Firestorm: In an awesome display of flaming lava and molten ash, Anak Krakatoa - the child of Krakatoa - reveals its latent power. In recent years, eruptions have steadily grown in intensity

Devil’s cauldron: Krakatoa’s eruptions draw in violent thunderstorms, adding to the air of menace

Chapter 6:Photographs and the environment

Dear Gentlemen,

Just as we wrapped up Chapter 6 on photographs and how to interpret it, do visit the NASA website link (in case you do not know what NASA is, it's called National Aeronautics and Space Administration and it's set up in the U.S.A) here

Below are just some photos take from the website, it's really mainly photos about space and the Earth, which reminds us on ow we should protect Earth and appreciate the beauty it has to offer to us ...=)

Enjoy the weekend!

Chilean Earthquake Shifting the Earth Axis!!?

The diving tectonic plate at the epicenter of the magnitude 8.8 Chile earthquake Saturday helped to temporarily redistribute mass on Earth.

Dear Gentlemen,

Recently, the a 8.8 magnitude earthquake struck Chile and now scientists are saying that it has caused the axis(remember it's imaginary) to shift,causing the spin to be not as fast as before, resulting in shorter days...

Look at the video below to understand...

NASA explained that the key to the shift was due to the location of the Earthquake, with the fault slicing through Earth at a steeper angle, making "Chile fault more effective in moving earth's mass vertically and hence more effective in shifting Earth's figure axis.

You can click on NASA website to read and find out more.

Though devastating, it is really interesting on how what we were studied before and what we are studying now and in the future are really things happening around us NOW.

So remember that our actions and interactions with the environment is very important. =)

How a Handphone is recycled

Hi Gentlemen,

As what I posted in the previous two posts, I mention about the initiative the school is having in terms of recycling old handphones or accessories, do take time to see how our handphones can be actually recycled into different plastics, ceramics and metals that can be re-used for the production of other handphones or even other products (like gold used in your mum's jewellery =P )

So visit Nokia's website and learn more about it.

Cheers,
Miss Zheng

Hi Gentlemen,

Just as we are studying about our environment and how we should care for our environment, also how there are interrelationships between humans and the environment, I just came across a smart advertising from the Nike, doing the Soccer Kit for the upcoming World Cup.

What caught my attention was Nike's attempt to be environmentally friendly in using recycled plastic bottles to come up with the Shirt in the kits they are selling. Awesome idea! See the pictures below! Quite an amazing advertising piece too =)

So in line with my previous post about recycling, do your part and remember to RECYLE your old handphones and accessories which cannot be used anymore!

RECYCLE YOUR OLD HANDPHONES IN CHS!

Dear Gentlemen

Do u have old rusty hps lying around your house? Well, here's something you can do to your "beyond revived" hp and the environment as well!

Your old mobile phones and other accessories can be broken down into recycled parts, and be used to make other objects.

A team from SAJC has collaborated with NOKIA to collect all spoilt hps and accessories from as many consumers as they can.

You can drop spoilt/rotten/beyond repaired hps and accessories in the huge green box with a Nokia Logo in the Secondary School General Office. The deadline is Friday, 1pm.

You can also pass it to me if you want! Spread the message to your family members and ask if they want to discard their unwanted handphones!

Do your bit, and save GAIA!!!!
