2. Mobile phones have changed our way of life but are they safe? Mobile phones were introduced in the 1990’s. They are now more than a million in use. In this project we will be looking at the health hazards and are they true.

3. Mobile phones work by sending and receiving tiny microwave signals. They send them to the nearest phone masts which send them to their destination. They also send other messages to other phones. When your phone is switched on, it sends a signal to the phone mast to say, “I am here.” Then the phone mast locks on to its position.

4. Scientists say that the mobile phone cooks your brain. Microwaves that the phone gives off goes in any direction. The microwaves are often absorbed by the thick bone of your skull or they pass through your skull and into your brain. These signals are so tiny you cannot feel them. Your brain becomes heated by the tiny microwaves but you cannot feel them. This does not mean that your brain becomes heated straight away. It does this over many years.

5. Disadvantages of having a mobile phone. Mobile phones may cost a lot of money. They can cause the brain to heat slightly.

6. For: Mobile phones can help you when you need help. Mobile phones will improve your lifestyle. You can do many things on a mobile phone. Mobile phones are a tiny miracle.

7. Against: Mobile phones have been thought to cook your brain. They have also been thought to cause problems with the human body. They are also expensive to buy and can cost a lot to replace.

8. Mobile phones have improved our way of life. But they can cause problems. They do emit microwaves but this should not affect us. So it is your choice whether you buy one or not.
