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

Please choose one of the questions below and post your thoughts.

(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.

Thief N.o 6

I (smeiled) smiled to myself, "This is easy!"

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.

He made a wicked smile ready to steal the diamond,reaching out with his enormous hand holding a knife ready to cut through the glass box and steal the diamond.

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

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

The (fat and) plump discipline mistress walked (along the way linked to) into the hall. (Everyone shut down their 'machine gun in their mounth' and the hall) The noise stopped (was as died) as in a deserted haunted house.

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.

Discipline Mistress 1

I watched in amusement as I saw the (ever so scary) Discipline Mistress (gave) give a lecture to HongWei (, a very annoying boy,) outside the noisy hall.

(The discipline Mistress was wearing a blue, long-sleeved shirt and pink skirt which looked tight on her chubby body.)(1)

Her face (was) looked frightening (with all the frowns) as she frowned and her angry eyes ( they were serious, angry and) were piercing sharp. Her gray and black hair was up in a bun and her glasses (were) dangling (off) on the tip of her nose shook with every word that came out of her mouth. ( her hands were on her hips clenched into a fist.)

I took a glance at the terrified Hong Wei and scurried into the hall, not wanting to meet the Discipline Misstress' eyes. (I saw the Discipline Mistress dismiss Hong Wei off, who was sobbing quietly.)

Mrs Chien: Some excellent observations make us see the Discipline Mistress well.

Physical descriptions can often be awkward, so refrain from using them. Instead describe people's actions which always lead to a more vivid picture.

Notice that by adding the phrase in red, I allow you to see how scary she is - I didn't need to tell you she was scary.

Thief 5!!!

The thief crept into the room quietly(,). (the atmosphere around) It was very quiet. The thief had (wrap) wrapped a piece of black cloth around his mouth to prevent people from recognising him. His eyes brightened when he finally found the gold he was looking for. (The thief) He put the gold into his bag and ran out in fear. "Bee Bee....." The security alarm rang(,). For a moment, he froze, (and) looked around and immediately ran out...


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

The big bully walked into the class of 35 pupils and started shouting at the students (,).
( 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?
