Writing Feedback / The hot air goes out of the house through holes in the attic hatch. How heat is lost in a home. [2]

The diagram shows how heat is lost and energy wasted in a house because air getting into and out of the house.

The diagram demonstrates the circulation of air into and out of the house which led to heat losses and waste of energy. Overall, most of the heat in through air vent in the ground floor, whilst the hot air out of the house through holes in the attic hatch.

Air leaks into different part of the house. Fresh air flow into the basement thru window and dryer vent in washing room, and it also came from crawl space that connect to outdoor faucet. In the ground floor, a small amount of air move into bathroom through the power outlet in the wall, while in the other rooms, air pass into the window, door, and kitchen fan vent.

Furthermore, the large amount of air that entering the first floor encourage the release of hot air directly onto the attic hatch, which is the main point of air leaking. Most air out via recessed light both in the bathroom and kitchen. At the final stage of air leaking in the house, air in the attic out into the open space outside the house through the bathroom vent stack and plumbing stack vent

Writing Feedback / The picture gives information about the process of retention and reuse of rainwater. [2]

The diagram shows how rainwater is reused

The picture gives information about the process of retention and reuse of rainwater. Overall, it can be seen that the process involves four major stages, beginning with storage, distribution of the water, and the cleaning process.

The procedure of recycling rainwater starts when the pouring rain accommodated in two different place, Dam and rainwater tank. Following this, rainwater needs to distribute from storages to the house by using pipes. But, before water for people's consumption transferred from the Dam, it must go through cleaning process in water treatment plant.

After the water is used by people for daily needs, it is become household wastewater which directly sends to wastewater treatment plant to be purified for making it available to use once more. Most of recycled water channeled back to the house, while the rest of its send to the river. In the river, it will be mixed with storm water which fell onto the ground.

Writing Feedback / The development of West Park secondary school since its contraction in 1950 [3]

The diagrams show the changes that have taken place at West Park Secondary School since its contraction in 1950
The alterations of West Park Secondary School development in three different stages of its development are illustrated in the diagrams. Overall, the most noticeable change is the establishment of parking area which was getting larger significantly, while the main building of the school was still in similar positions over six decades.

In 1950, residential area was built next to the main road and close to the school, and the area right behind of these buildings was farmland and playground respectively. In 1980, this housing area had been demolished in order to make two new areas which became car park and science block. Furthermore, the entire area of farmland converted into a sports center.

In 2010, the main building of schools and science block remained unchanged, while parking areas was extended to cover all of sports field. As a result, the size of both playground and sports field had decreased since the sport center took over some playground areas.
