Science- alternative use of kinetic energy

This will really happen sooner or later .When there are no more fossil fuels , I guess that everything, all of them, their prices would rise tremendously. Every family,by then, would have some solar panels or some sort of thing like that , it will be very common, everything is so high-tech.so , people will be using solar panels . nowadays , some people have small windmills outside their houses (for terracces and bungalows )that will spin when there is wind ,which is for decorative uses ,will be be used to create elactricity . but wind is unpredictable , so I thought of something , in taps , where the water flows out when the it is on, ther will be a mini turbine in the tap , though it will not spin very fast , but people use taps every single day , many times a day .so the turbine will spin when you use water , even in those showers . everyone showers , so lots of kinetic energy can be converted into electrical energy .i think many things will have turbines in them to convert in to electricity . alternative use of kinetic energy :if people use electricity to work exercising equipment, example, a trackmill so when the person runs on the track (holding handle ) the dynamo will convert kinetic energy to electrical energy . and if no one is using the gym equipment, the lights ,which depend on the kinetic energy converted , will not lit up , just like some of the places that use the same method to lit up the place .

Alternative Source of Energy

well we could used the solar panels to absorb the solar energy Is it true that if the fuels r used used up ,we hav to w8 a 300 millon more years more to hav another batch of fuels again?

Energy

Alternative Source of Electrical 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

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.

Label title:
(1) Alternative Source of Electrical Energy or
(2) Alternative Use of Kinetic 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.

Thief 3

The ever so sly and cunning theif sneaked into the museum which holds the worlds finest jewels.He wore a black mask whcih covered his entire face except for his eyes.He was wearing a suit as black as charcoal and had dark blue sapphire eyes.In one hand he held a big empty sack ,ready to be filled with the finest jewellerys there is.As he walked into the hallway he saw the most magnifecent ,beautiful and biggest diamond ever! kept in a glass box. 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 in her hand.She dragged Fauzia to the front of the hall.Her eyes looked very serious.Then,she took the mike and said ,"We have found the culprit of the person that tried to burn the toilet".Then she took out a cane from behind her back ,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.........

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.

Congratulations to an A* Team

6 Grace triumphed this year for Bukit Timah Primary Open-House 2008!
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!
