    Temptations TodayAn iPhone, among other

    smart phones are one of

    the affluent products in

    todays market. These will

    be seen in hands of justabout anyone these days.

    The multiple apps this can

    hold entertains anyone of

    any age and any

    background. Its useful,

    sufficient and easy to use,

    but do you really need to

    have one of them? Is there

    a more greener, alternative

    choice for everything thats

    in the energy consumer?

    LEND A HAND BEFORE ITS TOO LATE

    Global Warming, Climate Change, Pollution, sound

    familiar? It should, because as the human impact on this

    planet increases so do these appalling effects.A vital and immense part of daily human life consists of electricity. Humans today depend

    on electricity vastly, life feels so much easier and just better with electronic products. The worldtoday is confined with all kinds of electrical products. From the traffic light to your eBooks,

    almost all of things are connected with electricity. Life has gotten better, and more advanced,

    but the effects on Earth of all the Green House Gas remains unnoticed by many. Practically all

    of these electrical goods come from non-renewable energy sources like fossil fuel. Extra carbon

    dioxide builds up in the atmosphere from creating electricity and also using electricity. The

    additional carbon dioxide produced in the atmosphere generates the damaging effects to the

    planet. Earth is warming up rapidly, so the polar caps are melting, extensive droughts, and

    drastic weather changes are occurring around the world. There is still some time left to prevent

    further damage, but it is only possible if everyone participates. One of the major dilemma's we

    are faced with is the constant need to use a phone, laptop or other electrical

    device. Instead of taking a walk or reading, people are starting to use

    massive amounts unnecessary electricity. Not only is it affecting the

    human body, but the usage of these devices produce even more

    additional carbon dioxide. If people become more aware of

    how much they are using, and cut down to using only essentials,

    we will see a positive impact. Nonetheless, profiting from our

    renewable resources such as the sun, water, wind and ect. is the

    best solution so far. Its very obvious that we cannot just cease to

    using electricity, but it is extremely important we try.

    Every Hand Counts

    Every small thing that you can contribute to helping the

    environment. That is the most important skill that the students

    in Zarafshas 2013 class had learned. No change is small,

    everything and anything can help on the larger scale. Simple

    things like turning off your lights, or just not using the laptop

    for too long can some how help the planet.

    Because you never know, there might be a

    million other people around the world doing

    the exact same thing, and that would

    create a large positive impact. But its

    important to remember, every hand counts.

    We are forgetting to take care of

    the only home we truly have.

    The Promising Results

    A New LeafZarafsha, an eight grader at ISKL, has dedicated this year

    to be the start of a new, green life style at home. After a month

    of observing the electricity habits of her family, she saw to it to

    make some changes around the household to reduce their

    footprint.

    The Old LeafDuring the month of August, Zarafsha noticed that

    compared to many of the other families at her school, her

    families monthly electrical consumption wasnt that faulty.

    Looking around her house, she also began to see that herfamily did many things that were environmental friendly

    without even realizing it. The cause for the precautions taken

    by her family was probably the electricity bill that comes every

    month. The expenses for electricity has grown over the past

    few years. The Ahmed family were already using minimal

    lighting during the night, preferring to use small table over

    large wall lights. They used to only use 1 air conditioner at

    night, because the father did not live in Malaysia during that

    time period. Overall the family did have the basics, but there

    was still room for improvement.

    Vines of A New LeafZarafsha carefully crafted a detailed plan to help the environment by reducing her

    electricity usage. During her month of observation, she looked into many tiny details of

    her house to find ways of decreasing her consumption, but still be able to live normally

    in the modern age. Then for the next few months she kept track of her monthly

    consumption.

    Things she changed:

    While she was looking around, Zarafsha noticed that almost all the plugs in her house

    was constantly on. And there were a lot of plugs in her house, so she decided upon

    turning off all the plugs points that werent being used at the very moment, also

    reminding her parents that if need be they were allowed to turn on the plug but only if

    they could also turn it off when they were done. These sockets, she had seen sucked out a

    lot of energy invisibly, without anyone being aware of it. Another she had changed

    around the house, was the amount of time laptops and T.Vs were on. Gradually, using

    unnecessary technology decreased.

    Things she planned to, but did not:

    Zarafsha had planned on putting a timer on air conditioners, but failed to do so,because she found out that it was difficult for me to sleep with the air conditioner on, as

    the air grew warmer very quickly after it turned off.

    ETHICAL

    So Close, But Not Yet ThereAnalyzing the graph, it is evident to

    Zarafsha and her family that maybe they

    have not tried hard enough. Although inthe graph, the fitted line has a negative

    slope, its not very steep. Also the Ahmed

    familys general usage

    had increased by a lot

    since August. This

    might be due to them

    moving to a larger

    house during the

    middle of the year. It

    was during that time

    period that the family

    experienced a high

    leap in their

    consumption. Though

    they slowly came down

    to a lower energy consumption, in the end

    the consumption was still more than it was

    in August. At the beginning of the project,

    in August, the familys monthly

    consumption was 787 kWh, but in

    November is rose to 1035 kWh, which wasa 248 kWh increase. Fortunately though,

    the family slowly came down to a monthly

    consumption of 987 kWh by April. The

    Ahmed family doesnt seem to have a

    consistence change pattern, as some

    months they would consume more than

    the previous, but then they would also

    consume less on other

    months. But overall, the

    family decreased their usage

    more often than they

    increased, which shows that

    there is still hope in changing,

    just not very fast. During

    these months, the Ahmeds

    had began to wake up fromreality and grasp just how bad

    the situation was getting. The

    saw how difficult it was too let

    of some things like too much

    T.V, but they also became aware of larger

    and worse impact all these electricity was

    creating. Time is vital here, because the

    way things are going, it wont be long

    before theres no going back, there wont

    be anything to reduce when there is

    nothing.

    ETHICAL

    A Goal is SetWe thought that being able to use only

    300 kWh as a monthly was a good goal for

    families like the Ahmeds. To find the exact

    time it will take the Ahmeds to get there, we

    are going to have to find the equation for

    the graph. All we have right now it the fitted

    line, which we are going to use.

    The equation we are using is;

    y = mx + b

    The SlopeFirst, we are going to find the slope,

    which we are going to get using two pointson the line. To make things easy, we will

    pick whole numbers from the x-axis;

    (6, 900) and (8, 850)

    Using the rise over run method, we find

    the difference of the rise and the run

    (separately);

    900-850 = 50 = -25

    6-8 -2

    Now we have a part of the equation,

    which looks like this now;

    y = -25x + b

    To be able to solve the problem, we still

    have to find out b.

    Vertical InterceptThis is the part where we use

    substitution, because the two coordinates we

    used earlier are a part of the line and will

    have the same equation if the equation is

    correct.We will use the coordinate

    (6, 900)

    and substitute them fory and x in the

    equation;y = -25x + b

    Which would turn out like this;

    900 = 6(-25) + b

    Now we just solve the equation

    backwards.

    900 = 6(-25) + b

    First you simplify;

    900 = -150 + b

    Then you add 150 from both sides,

    because that is the opposite function

    900 +150 = -150 + b

    +150

    And that is b1050 = b

    Which mean, 1050 is my vertical

    intercept (y-intercept)

    At 300 kWhThe equation we figured out is;

    y = -25x + 1050

    Now we can plug in the 300 by

    replacingy with it, because if you look at

    the graph, the the kWh are on the y-axis.

    300 = -25x + 1050

    And we solved backwards again, but

    this time look for x.

    300 = -25x + 1050

    We subtract 1050 from both sides first,

    300 -1050 = -25x + 1050

    -1050

    Then, we do the opposite of

    multiplication and divide 25 from both

    sides,

    -750 = -25x

    -25 -25

    And then I have my answer,

    30 = x

    To check to see if the equation makes

    sense, we will put in all the numbers we

    found out into one equation like this;

    300 = -25(30) + 1050

    Multiply first,

    300 = -750 + 1050

    Then add,

    300 = 300

    So my answer makes sense because my

    equation equals to the number that I

    wanted, which is 300.

    So this means that it will be taking the

    Ahmed family 30 (wow..) months to reach

    about 300 kWh as their monthly

    consumption, that is if they continue their

    monthly electrical consumption as the trend

    in the above graph.
