The process of making carbonated drinks can be summarised into five stages. Firstly, the factory uses raw water which goes through a filtering process to ensure it is devoid of any impurities. Water softener and chemicals are added to the raw water and is subsequently pumped into electric heaters.

Secondly, the purified water is heated in the electric heaters where eveporation takes place. After, it passes through a cooling pipe and mixed with carbon dioxide in a process called carbonation. The carbonated water, in the third stage of the process, now enters the mixing tank. In the mixing tank, three ingredients are added to the carbonated water : colouring, syrup and flavour. This mixture is then thoroughly combined in the mixing tank. After the appropriate mixing time has ended, the mixture is filtered and filled into bottles and cans. It is also at this stage that the drinks are packaged. Finally, the boxes are placed in delivery trucks and whisked off to groceries and other places of business.

In today's society, computers can be found practically anywhere. Computers have made the world a smaller place and globalisation has made teaching much easier on the school systems. Students must realise that knowledge and information can more easily and speedily, be harnessed from a computer than a traditional text book. However, too much dependency on computers by the students and their teachers can also pose risks to students.

Firstly, computers are the way of the future. From youth, children should be exposed to a computer. They should explore the benefits are using a computer and the information that can be gathered from the device. Computers help students gain knowledge in an instantaneous way. One can go on Google and type in any subject and a barrage of information is at their finger tips. Flipping through a book, an atlas or an encyclopaedia is a thing of the past. In my opinion, there is too much information that can be found on a computer and this can be distracting to students. However, a text book can hone in to a subject area and give you the same information, in a more practical and educational setting. When using a computer, the barrage of information can be a distraction to students and can cause them to go off-topic when searching for a particular subject.

There is nothing like a human touch. I say this because students in the age

bracket of 7 to 12 years old cannot be left alone with a computer for a long period of time. It is at this crucial stage in their lives that these students learn more effectively though interaction with peers, questions to their teachers and modelling, drawing and creating by using their hands and their minds. This traditional form of teaching cannot be replaced by a computer. While I agree, a child of this age bracket must know how to operate a computer, total dependence of it for teaching purposes is not ideal.

Lastly, the health of students must be considered when schools intend to use computers. Basic ergonomics teach us that sitting behind a computer and desk for any significant period of time can put stress on your spine, neck and wrists. Additionally, doctors advise that after every twenty minutes of focusing on your computer screen, one's eyes must take a break. At this youthful stage, students and parents should not be worrying about harmful health effects of being at a computer station for long. Teachers must manage each student's time on the computer so that the maximum benefit is derived from it.
