I am doing a case study for physics with the hypothesis “Using a mobile phone affects our health negatively”. I have begun by looking at different websites for the facts. For example The Times article says that The number of mobiles in Britain has doubled to 50 million since the first government-sponsored report in 2000” and the International Communications Union tells us that “About half of the world’s population has a mobile phone today with mobile phone ownership worldwide topping 3.3 billion at the end of 2007”. This is confirmed below. These are just a few figures that explain how serious this hypothesis is. If it does affect your health negatively, then 3.3 billion people could be at risk. I have also stated my own opinion in a conclusion and

On the electromagnetic spectrum, a mobile phone uses radio waves to transmit signals and send and receive calls, messages, etc. Radio waves are the second weakest type of wave, so would not create much of a risk to the human body, albeit affect the tissue slightly. There is a diagram of the electromagnetic spectrum on the next page. “Mobile phones connect to the base station providing the best signal – usually the nearest. As a person moves away from the base station the signal becomes weaker, so the mobile phone automatically adjusts its own RF field strength to maintain the ...

Grammar, spelling and punctuation are all fine.

Whilst the introduction is good, the hypothesis should be set out separately from the introduction. In addition, the introduction is cut short. The candidate should also have cited the sources properly and then used a bibliography, which whilst they have, it should have been cited properly. The argument for and against mobile phones could have been expanded on, and the scientific studies behind the mobile phone theory explored a little deeper. The candidate should have also rejected their hypothesis, but overall a good attempt for this piece.

Overall a good attempt. The essay could have been set out in a much neater way to appear more sophisticated and accessible. In addition, the scientific research behind each point examine further, although the wide range of sources used and the analysis is to a good level. The conclusion is adequate and most of the essay is clear to read.
