Summer Assessment Revision Flashcards
Day 1
Scientists have now found out that blue-light can affect your body clock and sleep patterns if used late in the evening or in the night, which is what most phone addicts do on a regular basis. The light is “Short-wavelength-enriched,” meaning it has a higher concentration of blue light than natural light - and blue light affects levels of the sleep - including the hormone melatonin more than any other wavelength.Changes in sleep patterns can shift the body’s natural clock, also known as the circadian rhythm. This body function controls our wakefulness, alertness and dictate function in the body’s organs.
The hormone melatonin is released late in the evening and it peaks during midnight. By confusing your body clock with irregular light patterns, the hormone melatonin and even tryptophan can be delayed which means it will be harder to get to sleep … and we all love our sleep. Also bright lights can strain and damage your eyes, leading to vision problems and may result in YOU having to wear glasses. Is it really so hard just to turn your phone off?
Day 2
What is even more frightening is that the Apple iPhone 5 didn’t pass the FCC exposure guidelines for body worn operation if positioned less than 15mm (5/8 inches) from the body (e.g. When carrying a phone in your pocket). This can lead to cancer. European scientists recently did a test with non-ionising microwave radiation emitted from cell phones and found out that it changes and damages the brain and damages sperm. The mobiles also release erratic microwave radiation that can disrupt DNA, weaken the brain’s protective barrier, and release highly reactive and damaging free radicals.
Social Impacts
The presence of a mobile phone while two or more people are talking face-to-face can generate negative feelings toward the person who his or her device visible. In two studies conducted at the university of Essex in the United Kingdom, researchers studied the effects of a mobile device during a nose-to-nose conversation. In the first study, 37 pairs of strangers were asked to spend 10 minutes talking to each other about an interesting event that happened in their lives within the past month. Half of the participants were seated in a secluded area with a mobile device on a desk nearby whereas the other half remained without a mobile. The results showed that those with a phone were perceived less positive than those without one. In conclusion mobile phones affect your physical, mental and social life, is it really worth it …
Day 3
Everyday an average teenager spends up to 8 hours on electronic devices, which is more than 56 hours in one week. How much is too much? Technology is advancing every minute of everyday. New, phones, computers and other electronic devices are improving and outshining last year’s inventions. Teenagers are obsessing over having the newest and best phone, computer or iPod. Since teenagers are using technology devices everyday, they are beginning to isolate themselves from family and friends while limiting their communications skills. Technology is continuing to advance; however it is consequently affecting teenagers.
Teenagers are becoming addicted to technology, making them isolated from the real world. Teens mostly communicate through texting, online chatting or Facebook . Teenagers have stopped picking up the phone to call a friend or family member. Without verbal communication skills, what will happen to the future generations? Not only are cell phones and computers negatively isolating teens, iPods are too. About 86% of teens own an iPod or MP3 player. iPod and MP3 players also isolate teens by putting them into their own world instead of communicating with others. ( )
Day 4
( )The appearance is also isolating because the head phones in their ears hint that they just want to listen to music. While headphones are on it is hard to get a good conversation going. These electronics are isolating them and causing their verbal communication skills to hinder.
Not only are teenagers not paying attention during class; they are also taking the “text language” into their real writing assignments. 38% of adolescents say that they have used text shortcuts in schoolwork such as “LOL” (which stands for “laugh out loud”). Abbreviations and slang created for texting does not follow proper English grammar. Since teenagers are constantly texting, they subconsciously use this language in schoolwork. The texting language is limiting their vocabulary and written communication skills.
Although technology advancements are improving the world, teens need to be careful to avoid the negative consequences. Teens need to avoid addiction to electronics and isolation from family and friends. Instead, teenagers and young adults should engage in verbal conversation more frequently. To avoid electronic distractions, teenagers must follow school rules and laws. ( )
Day 5
Phones should be put away during class or while driving. Finally, they need to utilise proper English grammar as much as possible during formal writing assignments. Awareness of the consequences and trying alternatives will help them enjoy technology advancements in a positive manner.
