A question?
others form of energy
If energy used in Singapore (oil and natural gas) were depleted we can use renewable energy such as:
· Solar energy(solar panels)
· Wind energy (windmills, wind turbines)
· Tidal energy/wave energy(from a dam)
· Biofuels(plant) used in cars as petrol
Renewable energy now produce 13% of the world electrical:
Hydropower 2-3% and others including wind, solar, and marine energy together - less than 1%
Singapore average daily max temp: 30.9ºC / average daily temp: 23.9ºC
1) Solar panels which can produce 115watt of electricity cost average $640.
2) Shortage of land to build a solar energy power station.
Wind energy is a clean fuel source. Wind is actually a form of solar energy caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities. It is intermittent (not constant)Biofuels can be defined as solid, liquid, or gas fuel derived from biomass.
The first batch of biofuels used new plants natural sugar to make biofuels. This may lead to shortage of food as we do not have any extra land for growing our crops.
Examples of plant ethanol: sugar beets, sugar cane, corn, wheat and barley. Most trees and grasses are made of cellulose, which can also be converted into sugar, although not as easily as starch.

Alternative source of kinetic energy
Alternative Source of Electrical Energy
The first option we could use is hydro-electric energy which seems to be expensive but much more convenient than that of a windmill as the wind is unpredictable resulting to a unsteady supply. Hydro-electric energy are much more constant as the water will be rushing at it most of the time - unless there is a drought of course.
The other source would be the wind mill.Yes, it has an unsteady supply but it is much CHEAPER than Solar energy. And it's enviromentally friendly too! (well, it should be...)
Moving on, We have the Solar panels. Solar energy is good and enviromentally freindly but what's that? Yes, it is VERY EXTREMELY EXPENSIVE. And, we need a great amount of solar energy to have an adequate amount of electricity. Another fault, at night, we won't get any energy, unless there's a device which saves the electricity of course!!!
So what should we do is there's not enough electricity? Two answers:
1) Use less electricity!
2) Combine the electricity from the alternate sources!
Fauzia's note: Hello! I managed to sneak on to the computer to do this!Anyway, If I did something on my answer that shouldn't be there, please tell me! Thank you!

making eletrical emergy with kinetic energy
~thank you for reading my writing~^^!~
Altenative use of kinetic energy
1) Power the street lights.
2)In soccer courts, we can use the kinetic energy which the players use to kick the ball to power the score board and the lights in the stadium.
3)When people use bicycles, we can use the kinetic energy that people use to paddle to power the lights of the bicycles.
4) In schools, the kinetic energy that the pupils use to play can be converted to power the speakers, lights, fans,etc.

Science- alternative use of kinetic energy
Alternative Source of Energy
Energy
We may have to depend heavily on Hydro-electric stations,wind generators and solar panels and last but not least,save electricity.
Alternative Use of Kinetic Energy:
We could make a better use with converted kinetic energy with the biycle dynamo

Alternative Source of Electrical Energy
We can build a hydro-electrical power station or use solar batteries(?).We could also save electricity and use less fossil fuels.
(All this questions are so HARD!!!!)
Science Lesson 2
(1) In SAM recently, Wei Zhi wrote about energy conversions and posed the following question:
As we use fossil fuels - natural gas and oil in Singapore to convert chemical potential energy into electrical energy, what are we going to do as these natural resources are running out?
(2) Most of you talked about the chemical potential energy we store from food. You also talked about how we convert this stored energy into kinetic energy through moving aound.
Imagine you are all running around playing football (yes girls included).
Can you think of how we could make better use of this converted kinetic energy while we are running around?
Remember that answers are to make use of your knowledge of concept of conversions of energy.
Label title:
(1) Alternative Source of Electrical Energy or
(2) Alternative Use of Kinetic Energy

Thief N.o 6
The world around me felt like (have been pause) it had paused. There (were) was no light, no animals around, no human beings - only the moonlight was accompanying me.
Fishing in my bag, I took out a rope and threw it over the nearest tree.
Feeling (confidence) confident, I climbed up the ladder and jumped across (to) through the opened window.
The darkness fell around me (,) as there was (even) no silver moonlight here! Putting on my special glasses, I looked around the room ... only to (find) hear a voice whispering (at) into my ear, "What are you looking for?Young Lady?"
Mrs Chien: This scene was well described. Not only can we see the triumphant and reckless robber, we can also sense his deep surprise.

Best Descriptions Awarded
Wednesday, February 13, 2008
Thief 3
The ever so sly and cunning (theif) thief sneaked into the museum which (holds) held the world's finest jewels. He wore a black mask which covered his entire face except for his eyes. (He was wearing a suit as black as night and had dark blue sapphire eyes.) In one hand, he held a big empty sack ready to be filled with the finest jewels of all colours.
As he walked into the hallway, he saw the most (magnificent, ) eye-catching and biggest diamond ever! It was kept in a glamorous glass box.
He (made a wicked smile to himself) smiled wickedly (and got ready to steal the diamond,) reaching out with (his) an enormous ( hand holding a) knife, ready to cut through the glass box and steal the diamond.
Mrs Chien: I can see this thief! This means the description was effective! Yes!
Now, sometimes, it's better to refrain from physical descriptions as they can sound awkward. Instead describing people's actions is more interesting. Also 1 brilliant adjective can be better that 2 not so great ones.
Discipline Mistress 2
By Hong Wei
Everyone kept silent as the Discipline Mistress walked into the hall. She was holding Fauzia's hand and dragged her to the front of the hall.
Her eyes looked very serious ( she took the mike) and taking the microphone, she said harshly, "We have found the culprit who tried to burn the toilet". Slowly, she took out a cane from behind her back while a table was dragged to the front of the hall.
Fauzia stood forward and as the Discipline Mistress raised her cane I closed my eyes.........
Mrs Chien: Successful description that allows us to see the action on stage.
Try to create smooth movement in between sentences.
Discipline Mistress 3
She took out a notebook and called out the ('criminals') names(, ) (mine friends) Justin and Pete prayed hard (to god to let them off this and the only time but they all know what was going to happen to them.) not to be on the list.
When their names (was) were being call they knew that they are going to bear the consequnces of damaging the school property.Last week, when they are being questioned by the disipline misstress they denied it but the dissipline misstress found out who was the culprit. So today they are going to be caned!When the disipline misstress gave the order the teacher hold up the can and slash,that hurt!! screamed of pain echoed the hall and that certainly sent down shrill down mine spine,mine hands feel wet and numb.....
Mrs Chien: In the first part, there is an attempt at using your senses to make observations at what was happening in the hall. That is good.
But in the second part, you revert back to telling the reader eveything and the story immediately lost originality and momentum.

Thief 5!!!
Mrs Chien: Some good observations were made.
Try not to repeat the same word over and over - that will make your reader lose interest. Here oyu used the word 'thief' 3 times. You can use other synonyms like - robber, the man, the intruder...
Bully 1
( he said,)
' Whoever wants protection from me, has to pay me a fee of $20 a week!'
Everyone was afraid (1) of him as he was the most notorious (2) student in our entire school! (He went to a gang fight with 50 of his gang members at the void deck of Toh Yi Drive Blk 123 . he and his gang members took metal poles and some even took out Parangs' and went there to fight!!!! So now everyone is afraid of him. Even the biggest , largest and the scary looking Jordan was afraid of him!!!!)
Mrs Chien: How would someone scary look like? And how do you know when people are afraid?
For example: (2)
Even Jordan, the biggest bully in class dared not look at him. Strangely, I could hear the tick-tocking of the wall clock or was it coming from my own heart?
Also read my comments.
Spiderman 3 / Best Spiderman ***
Finally, Spiderman forced the Scorpion King to a dead end, where its grave was. Crowds cheered,"Hooray! Spiderman is our hero!!" Flashes of lights (shined) shone (through their) into his eyes. Spiderman (is) was gone(,) and will (never) not return till there is trouble.
No trouble, no spiderman.
Mrs Chien:Yes, I can see Spiderman because the verbs and vocabulary you used effectively showed me the action. Also I can hear the excited crowd.
Marathon 1
However, I (have inspire to walk and run to) my dream was to become a marathon runner ( which was my dream). (Now, I am 21.)
I had been practicing walking (,) and running for the past few years. It was as difficult as climbing the 'Mount Everest'. Now I (am) was ready to run the 42km marathon. My legs were trembling (like a vibration in the handphone)(1). Soon, the marathon (was) started.
(Everyone which were about) (2) Two thousand people were jogging for the first few minutes (and) but they were getting faster and faster. I had a difficulty catching up with them. (The track was filled with cheering voices.) (3) and (There was) a few people even ran like mad cows. I felt like dying very soon as (it) I was very tired.
(While running for an hour, I saw a man with a brand new suites with the cost at the back part of the shirts. It was so expensive that i could not remember the number.) (4)
There was no one infront of me. I knew I was the last and felt terrible but soon I saw a sign "1km away to the end! HURRY!!!" then my feet (was getting) felt cramped. Suddenly I thought I heard (But I saw) my family members (were) cheering very loudly (that I can even hear them) even from a few hundreds metres away.
I knew I (have) had to try my best to achieve my dream. So, I ran as fast as my legs could carry me. ( and reached in a few minutes.) When I reached the end (, they gave me the medal of finishing the 42km marathon. Although I was not the winner, i was glad that I had finished the race. ) I smiled showing my ugly teeth without shame.
Mrs Chien: Attempts at making clear observations are excellent. I can see this marathon runner working so hard and his huge smile at the end!
Now don't be fazed by the large amount of corrections:
(1) Comparisons like the injured zebra are very effective in helping the reader imagine what is happening - in the case of the trembling legs, comparison is not needed.
(2)he word 'everyone', 'everything' is not useful to the story - always be specific - spectators, runners ...
(3)This observation does not fit into this paragraph where the main idea is about how hard the runners are working.
(4) Same as (3).
Finally, continue to work hard at changing actively how you view 'compo writing' and soon you will see improvement. Next time, attempt smaller pieces of writing and focus on a few sentences at a time.
Old man 1 / Best Old Man ***
His face was scarred and wrinkled. After he sat, he gave me a toothless grin as I managed to say 'hi' to him. After a few moments of silence, he began mumbling to himself. I pretended I did not hear him and instead I stared at his raggedy clothes and shoes.
(At the next stop , he went out of the bus as he did not have any more money to continue his journey. He stopped at the streets of chicago and went a long way. It was a cold night and i wondered how he would survive out there and alone ........)
Mrs Chien: I can see the old man too and I can sense the author's kindness and empathy with your effective use of descriptions.
Keep on expermenting on adding deatils that develop 1 main idea at a time. Notice that if I remove the words 'I pretended...', a link would be missing as this is a totally different idea.
Marathon Runner 2
In my mind,voices chimed in my head, shouting, "Go! Go! Go! You can do it!" After what seemed like an hour, I saw the one mile sign. Beads of perspiration dripped down my face and I heaved a sigh of relief.
Mrs Chien: I see the scene and hear all the exciting sounds. Excellent transformation of writing with effective choice of words and great application of strategies taught.
This means your mind is extremely flexible if Sheryl allows it to.
Oldman 2
(None of this would (happen) have happened if his unfilial children did not kick him out of his home. He was walking when he saw an mercedes benz passed by him. It braked next him and one of his richest nephew stepped out......)
Mrs Chien: Good attempt at using your senses in the first part but then in the second part, you went back to 'telling' me instead of helping me to see the old man.
Spiderman2
Marathon Runner 4 / Best Marathon Runner***
After a while we (reach) reached (to) a sign (where it) which read Mile One. Torturous days of training had paid off. (After) Hearing my family cheering me on, I felt a surge of energy and I started dashing through person after person like a horse in a race.
Mrs Chien: Observations effectively bring the reader to the scene! The wonderful caomparison at the end is original and impactful.
Now that you can use the strategies, it's time to develop each idea by adding more details.
Marathon Runner 3
It was an amazing sight ,and for the first time, I started to relax . But that did not last for long (,) because soon I broke into a sweat and my hands were clammy . (Suddenly, an old-looking man patted me on my shoulder and said ,'' Don't be nervous ,experience tells me that ,in marathons , one should never give up and never stop believing in yourself ,you can do it ,you can do it !"He then gave me an encouraging smile that gave me the courage .I wanted to thank him but a)
A (official-looking person) man shouted in a stern voice,"Line up and get ready to run !" Soon , it was as quiet as a cemetery. (The) Courage somehow ran out of my body and I felt butterflies in my stomach as my body tensed up. But a voice in my head rang loudly, cheering, "You can do it !You can do it !" The man blew a horn so loud ( ,) that I nearly jumped out of my skin.
(the marathon has started ! Five thousand people started running at the same time ! After what seemed a while ,I saw a 1 mile sign as the wind blew onto my face , i smiled a wide smile with a proud look on my face .)
Mrs Chien: Excellent use of feelings and keen observations allow the reader to be at the scene.
Now, it's so important to know when to focus your thoughts and not add extra details that will remove the excitement form the story.
Also be careful with your commas - when in doubt leave them out.
Discipline Mistress 2
Thief 2
Old Man3
After that, he continued jogging, happy that he had done his best to help the old man.
Mrs Chien: You 'tell' too much. A writer describes to help us see and feel the scene and event. Try again. Please see the following. Can you see the man on the ground? Can you feel his pain?
The old man stumbled forward, his wrinkly hand trying to break his fall. Surprisingly he seemed to fall quietly like a leaf from a tall tree. His eyes immediately closed tight. He remained very still as if he was taking a nap except that his legs lay in an unusual position.
Spiderman 2
Reporters rushed to capture pictures of Spiderman. Flashes and clicks were heard. In two split seconds, Spiderman was gone.
Mrs Chien: Very effective use of varying lengths of sentences - some short and crisp and some longer. But you need to learn to develop your ideas.
Thief 3
One of his (tricky and crafty hand) hands carried a sack, while the other seemed ready to grab the valuable treasure. As soon as he reached the special room (of the treasure), his eyes (were) locked on (it) the prize. He could (taste the treasure) sense victory already. With trembling hands he reached out for (the treasure) it. Sweats of anticipation rolled down his (greedy) face. The moment he touched the (treasure), golden statue, he gave a sly smile of success.
Mrs Chien: Ideas to help reader see the scene are excellent.
Repeating 1 word several time will make your story uninteresting - you used the word 'treasure' 6 times. Always find alternatives and use such words once in a paragraph.
Bully1
Mrs Chien: Why place all 3 ideas in 1 sentence? Please try again and slow down and develop each idea at a time.
Spiderman
Mrs Chien: You did not apply any of the startegies discussed in class. Please try again
Oldman 6
People walking past him were sickened at the sight of him as he smelled. (of at least 600000000dead bodies combined together.) So he (had to keep) kept moving from place to place (. Many shop owners chase the old man from alley to alley ruining their business with his smell.Indeed the man somtimes would) often shedding tears thinking of how his children were doing.
Mrs Chien: Effective ideas. Note how less is often better. You must learn to focus on 1 main idea at a time.

Science Lesson 1
In class today, we discussed the various types of mistakes students make when answering open-ended questions in Science.
Vague answers:
(1) Answer is not specific to the question
Pupils do not understand the question
- You should highlight key words to understand the question
- Always write down 2-3 highlighted words to focus on
(2) Answer is not specific to the concept tested
Pupils have chosen focus key words but cannot link to the relevant concept tested
- Learn to activate your Science Sense - some key words will give us a clue as to what the concept is
For example:
thermometer tells us we will be testing the concept of heat and maybe heat transfer
copper / paper tell us we will be testing materials and maybe heat or electrical conductivity
(3) Answer is not specific to the situation
Pupils give a general answer that is correct but failed to connect to the situation discussed in the question
For example in a question that asks you to explain why you chose the 'Lead ball' as your answer:
- Not specific: The bigger the mass , the more gravitational potential energy
- Specific: The lead ball had the biggest mass as it made the biggest indentation in the soil and therefore had the most gravitational potential energy
That's all for today. Give the above startegies a try!

English Lesson 1: Continuous Writing
Do you enjoy reading anything boring or cliched?
No! We are all captivated by something original, novel which makes us want to find out more!
How do I do that?
Easy!
Your first step is to dig deep into your own experiences. You might think you don't have that many experiences but then you are lucky, simple everyday experiences can be the most exciting.
Take the example below:
Silently, she walked up the aisle (1). She stopped and the entire class stared not daring to breathe(2). Slowly, her right arm placed a book on Peter's table. He looked straight ahead not batting one eyelid, his eyes half closed and his head bent almost in prayer. (1)
"Next time, don't read during assembly," she murmured (2).
(1) Used Sense of sight
(2) Used Sense of hearing
I am sure you all remember that incident.
Then make good use of your observations in your writing to transport the reader into your story, helping him/her see exactly what you are describing!
Congratulations to an A* Team
We were crowned:
Best Decorated Stall
Best Earning Stall
Nothing is impossible when creative minds mix with passion and dedication.
This is the most invaluable lesson for all of us this year.
It has been my greatest pleasure to work with 34 enthusiastic and driven pupils of 6 Grace.
Merci mille fois!
