Electronics Challenge




This is my electronic model I have made for
our electronic challenge. As you can see it makes a fire engine noise
and has a light.
Hope you enjoy.

Is it good to save Energy

Why do we need to save energy?
(So our world can live in a world full light not full of darkness.)

You’ve heard parents say “Turn THE LIGHTS OFF” OR “cLOSE THE FRIDGE DOOR” AND YOU WONDER WHY?

Just by making some small changes to energy in your house will help you save money and help earth be a better place .Energy has been there when we’ve needed it.bUT If we use too much energy that is bad for our earth like Methane and Co2, a very bad  gas is released and  that is called greenhouse, sOMETIMES when we leave something on when we are not using it you might think it is not a big deal but on the other hand you are making global warming a bigger and more dangerous thing for us. if we carry on using too much energy you are looking at massive floods and huge storms.

ENergy is important, if there was no energy how would we live? Save energy by not using too much and have a energy power plan on how to save energy. The best part of saving energy is that if you save heaps of it you will save a lot of money. We would barely survive without some energy sources but the biggest source of energy you  can find is the sun, if this big ball of fire  disappeared for some reason all of us will perish including the earth itself. So when you do something including energy have a little think about what damage it can do to our earth.

Energy is a very important to us and we use it in some good ways but using cars and other transports  that make global warming more dangerous is a very big problem, there is a easy solution to this, it is to just walk once in awhile or riding a bike,you can even help by simply changing a lightbulb to a more efficient one.
So our personal opinion is that this can help with the war against global warming.This is why you should save energy, i hope you have learnt something from this.

Thank you for listening to this piece of writing from tupou, misimoa and sake.

Room 8 Learning about statistics

                             On our chart it has the amount of votes what kind of fruit we would want to have everyday. Mango had the most votes then all of the other fruits like apple,banana,pineapple,orange and Strawberry. Mango had 14 votes apple had 2 votes pineapple had 7 votes and so on but banana had the least.

Electricity Journey

Is Mother Nature important? Yes, Mother Nature gives us non-renewable and renewable sources like Fossil Fuels from inside of the earth, Hydro Power from water when it rushes through, Wind of course from the wind, Geothermal from the heat inside of the earth, Solar energy from the sun, Biomass from the plants and Wave energy that is produced from the waves. Currently people predict that someday our non-renewable resources will go.  But with all of these complex ways you can make electricity, how does it become something that we use every day with the flick of a switch?   This explanation will describe the journey electricity takes from Mother Nature, to our homes.

Inside of a power plant is a generator. Fuels like Coal, Natural gas, Biomass and Uranium are used to heat the water until it produces steam which powers turbines and then this wonderful process generates our electricity and can be reused over and over again.

These power plants can’t be too close together so we have power lines, carried by tall towers to carry the electricity from a power plant to a substation, that you might wonder why they’re there and what they do.

When the power lines reach a substation which have transformers in them that can reduce the voltage so it is enough to power up all of our homes in a city or the whole country.

Just enough electricity has to be generated to our distribution lines which reaches our light switches. Too much or too little power, can crash the transmission system that could create a power outage or a blackout and this could affect the city if it did happen.

Some cities that usually have power like New York or such have been struck by an unfortunate hurricane (Hurricane Sandy) and have ended up with no power.  It has been one week after the hurricane and some people in New York still have no power at all and it is one of the biggest cities in America. What would you do if you had no power?

After all the process the the electricity powers your mains box and your outputs that you can use to power your homes. If you think that it takes one person to make a lightbulb work, then you're wrong. This explanation shows just how complicated it really is just to power your homes.

My Tukutuku Design

     My meaning of my tukutuku pattern.
The green represents the grass of a cemetery and the grey represents the gravestone of my grandpa who died in 2010. The white is the pathway to heaven so his spirit rises and goes to heaven. the blue is the sky of the world and the white on top of it is heaven.
