Air pollution
There are many causes of air pollution, as stated in the textbook.and they are the following, volcanic eruptions, forest fires, industries, motor vehicles and construction work. They are all being explained in the textbook and we would like to shift our focus on the motor vehicles part. Yes, indeed the Motor vehicles produced carbon monoxide and nitrogen oxides which pollutes the air. And thanks to chemistry, we all know that the formula of carbon monoxide is actually CO(1 carbon atom, 1 oxygen atom). Well, in physics, we learn that since carbon dioxide is CO2, all we just need to do is to force one oxygen atom into each molecule. I can't really remember what the technology appliance is called but some places in the world uses it. This way, as carbon dioxide is not as harmful as carbon monoxide, we believe that it can be a possible response.
My answers to Page 81 of the Textbook
1. The B-777-200LR had an extended range by more than 2775 kilometers compared to the other planes in the 777 family. It allows for non-stop services between cities. It can carry up to 301 passengers up to 17466 kilometers.
2. The advantages is that it is faster and can transport more people at a time, thus leading to fewer flights needed to transport a certain amount of people. Some disadvantages is that some airlines company may not be able to afford it as it may be costly, due to its title as the world's longest-range commercial plane.

Transport and Communication
Without reading the notes, this is what we know:
Transport and communications play a very important role in our lives. We need transport to move around in the fastest way. Imagine taking 5 hours just to get to school! Calculate what time you would have to wake up! We need communication or else we will be in our own world. Each of us thinks differently and if we don't communicate, then we would forever be on each other's nerves, 'my' world clashing against 'your' world.
Tramsportation in Singapore is not exactly what we call 'first-class'. The reason is because of the recent MRT delay or breakdown. But from the recent MRT breakdown, we can see how we are affected if we do not have transportation. As for communication, we believe Singaporeans to be the first. That's because people are always communicating, through multi-media or face-to-face. All this mordern technology sure made communicating faster and easier. Now, imagine if all communications were taken away. Some can't even live without a mobile phone, how can they live without voicing their thoughts out? I always gat an irritating tempt to voice out my thoughts whenever I feel like my thoughts were really good. So I guess, I'm lucky to be born into a world with transportation and communication.

The exam paper
Well, geography exam was the very first exam this term and it was a complete stunner.Like Ms J said, this year's paper tested on our ability to think and not about our ability to memorise. The last question was a prove of it, something to do about why farmers diversify their crops. First of all, we did not have enough time and secondly, we did not know what diversify means. After checking out from our classmates, they said that diversify means different. So actually, to put in into simple words, the question was asking why farmers plant different types to crops. Thank goodness, before the time ran out, I managed to squeeze in a few words. My answer was to make maximum profit. Thinking about it know, I believe that I can get a least one mark. Let's give an example: If a farmer plants rubber trees and banana trees, he sells each crops for $3. So lets say he have 10 of each tree, therefore, making a total of $60. But if his banana trees are infected with some kind of virus and dies, he can still make $30. Imagine if he only have banana trees, then he will not make any money. And there was also the first question, the only where there were three circles and they ask what A was. Does anyone know the answer?
Agriculture conference 2016 - Hosted in Singapore!
My partner and I saw a newspaper article today regarding Singapore preparing to host the agriculture conference in the year 2016. The article stated that our bid won even though our small country was competing against bigger countries bidding to host the conference such as Canada,the second largest country in terms of land mass. The article said that the reason we won the bid could be due to our high levels of food safety, agricultural dvelopment and research, as well as our favourable location and climate. Also, another reason could have been due to two Singaporeans who did a presentation of our far based tourism at the 23rd agricultural conference in Scotland. ( The one that will be held in Singapore would be the 27th one )
Another reason why we won the bid was because of our 'effeciency and facilities' said by Mr John Bennet, a RASC board trustee. What he said made me think of the current topic that we are learning of transport and communication. This is because the word 'effeciency' brought to mind of the recent breakdowns in the MRT systems posted on Ms J's blog. What if the MRT breaks down again when they people from all over the world come to attend the conference? This might be a bad reflection of our country, and this highlights the importance of the topic that we have just started on, transport and communication.

Agriculture
In class, Ms J told us that we could compare the different cultivations we learnt and post them on our blogs. There are 4 types of cultivativations and they are:
1. Wet rice cultivation - the growing of rice crops in flooded fields
2. Plantation agriculture - commercial farming involving one ot two types of crops for sale
3. Shifting cultivation - making temporary clearings of sites within forests to grow food
4. High-tech farming - the growing of crops or animal produce using modern technology
We can compare these 4 cultivation by three main components, the purpose, the inputs and the outputs. Let us first compare them by the purpose of growing these cultivations.
Wet rice cultivation - For substinence and also commercial farming.
Plantation agriculture - For commercial farming
Shifting cultivation - For substinence
High-tech farming - Commercial farming
( Commercial farming is mass produce and the purpose of it is to cater to thr public and not grown for survival while substinence farming is for survival. ) As you can see from above, high-tech farming, wet rice cultivation and the plantation agriculture come under commercial farming so the amount of crops yielded must be higher than the rest. Shifting cultivation and once again wet rice cultivation are also classified under substinence farming so the amount of crops yielded should be lesser. If ou have noticed, wet rice cultivation comes under both categories. This is because this type of farming was used to be grown for survival but over the years, the demand for rice has grown and thus some wet rice cultivations have been turned to commercial farming to meet the needs of the people.
Inputs
Inputs are what has been invested to grow the crops in the different types of cultivations, or also what is needed to grow these cultivations. These inputs can be furhur broken down into 4 components,
Land size - the size of land needed
Level of technology - how modern the technology is
Capital inputs - the amount of money required
labour inputs - the amount of labour required
Wet rice cultivation
Land size: Smaller land area needed compared to the rest.
Level of technology: Low amount of technology and simple tools used.
Capital inputs: The capital input for commercial farming is higher than for substinence farming
Labour inputs: High amount of labour input.
Plantation agriculture
Land size: Large land size
Level of technology: High level of technology due to use of pesticides and fertilizers
Capital inputs: High amount of capital input because of the need for supporting infrastructure.
Labour inputs: High amout of labour.
Shifting cultivation
Land size : Large amount needed as the people need to move from one plot to another.
Level of technology: Low level of technology, only simple tools are used.
Capital input: Low level as it is only for substinence
Labour input: High for clearing of land, but low for the harvesting and planting.
High-tech farming
Land size: Small land area needed.
Level of technology: High level of technology used.
Capital input: High capital input for buying machinery and fertilizers.
Labour input: Small amount of labour needed but the workers need to be skilled in the job.
As you can see, the most modern type of farming would be high-tech farming while the lowest would be the shifting cultivation. This can also tell you about the countries which have these types of farming. For example, countries with high-tech farming would most probably be developed countries while those with shifting cultivations might be less developed countries.
Outputs
The outputs are what is the amount of result from all the farming.
Wet rice cultivation - high output as it is a type of commercial farming
Plantation agriculture - high oput, but usually of only one crop
Shifting cultivation - low output as it is only for substinence
High-tech farming - high level of output.
As you can see, all the types of farming vary in all aspects of their outputs, inpunts and the purpose of their agriculture. They are important as they cater for mans needs interms of food or for raw materials so we should place them of high importance.

Linking back to topographical maps
Through learning about populations, we went back to learning how to recognise the different kinds of settlements on the topographical map. So, our last year knowledge does come in handy this year. To summarise up the lesson:
Nucleated settlements: Commanly found in places with industries, offices, community centers, buildings... It is like a town or city.
Linear settlements: Placed along main routes of transports
Dispersed settlements: It can be found on flat ground or steep ground. The people who stays in them are usually farmers.
Okay, so here is the big question: Serangoon Gardens is located in Serangoon. It has housing estates and shops and offices. It even have a community club but it does not have a community center. In my opinion, I think that it is a linear settlement as the houses are located along a main route of transportation- the road. However, my partner has classified it as a nucleated settlement due to its various facilities. So, what do you think it is?
