Altenative use of kinetic energy

I think we could use kinetic energy to.....
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.
i think they can create something that can absorb carbon dioxide then convert into electrical energy and put it at the place that need electric, so there will be electric all the time!!!

Energy - Alternative use of kinetic energy

We can use those kinetic energy we use in walking, running and playing using some energy conversation heat, into electrical energy such as, lights , fans, televisions, computers, and even mp3s or mp4s. This can reduce the usage on using too many fossil fuels which are now scarce all around the world.
i think they should put something on the pathway so when people walk on it ,the lights will automatically be turned on .

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

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.

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!
