Noise Pollution

Noise Pollution

Noise is sound that is unwanted, telling us a lot about the meaning of noise pollution already, pollution is an excess that is also unwanted and does not do good. Noise pollution is a problem that we are being affected by in the modern age, although not considered as big or important as other sorts of pollution, global warming or other, it is still a serious problem. Noise pollution sounds funny, and many people do not take it seriously because they don't know what it is. Noise pollution is excessive, loud sound made by either animals or humans mainly coming from either transportation or construction sites. Noise pollution is hidden in a way, problems could be appearing in your life that you did not know the cause of, something as simple as noise pollution could be the cause. Noise pollution affects both our mental and physical well-being in many ways such as hearing loss, aggression and annoyance.

Noise pollution affects many people, some not as much as others depending on the location. In large busy cities noise pollution is all around us, bus's creaking their breaks, and construction workers drilling and expanding new roads and other. Now, you might think you are used to this and that you hear all this stuff every day and it doesn't affect you but you may be mistaken. Did you ever wonder why some people talk about the joy of small villages and how relaxed they are? A big reason for this is the smaller if not non-existing amount of noise pollution. Noise pollution effects can vary from person but have two main categories, effects on our physical health and on our mental health. Mostly, noise pollution causes aggression and annoyance but the effects can grow into more serious things such as hypertension, a cardiac chronic condition and other such as tinnitus, sleep problems and even hearing loss. Hypertension for instance can lead to strokes meaning that noise pollution can be deadly, and guess what, a barking dog is considered noise pollution. The following that i displayed are of course a bit of the extreme cases, but it is proof that it should be taken seriously.

The problem with noise pollution are the effects it brings, it is not so terrible to bare but the side-affects are very serious that is why you should try to avoid areas with lots of noise pollution. People who live in areas with high noise pollution dislike it, and even would pay yearly for a reduction proving how much it is affecting them. This fact was proven by a survey in Sweden saying they would pay 4 euros per decibel yearly to lower the noise pollution.

Earthquake safety

There are several things that you should do if you were in an earthquake. The first, and most important thing, is that you should stay away from wobly, heavy objects, that could collapse and hurt you. This would also include windows, and any other glass objects. You should also move away from bookshelves. One thing that you shouldn't do is to panic. You should also always have a safety kit. In it, you should have materials to help wounds, as well as disinfect them. When in an earthquake you should have food that doesnt expire easily. You should also have a telecommunication device so that you can be found. If you're outside in an earthquake, you should move into an open space, so that you can prevent lethal injuries from collapsing buildings, trees, etc.

My house is very old, so it is not strong. It has many wooden beams that could easily break so if i had the time to i would leave my house go to my backyard and go into the "hole" in my backyard. If i did not have time to leave the house, i would get under the couch because it has a heavy mattress over it and nothing can happen to me. If i had to evacuate the house i would have 4 doors to leave the house and one to leave to the city. If i had to change something about my house i would demolish it and make a new one. My house has many glass tables, windows and beams supporting the structure which would snap easily.

Tsunami essay

Tsunamis are one of the most dangerous natural disaster. They kill up to hundred thousands of people. An example of one big tsunami would be the one that struck Indonesia, Sri Lanka and over nearby countries. This tsunami had a magnitude of 9.1/10. This magnitude is of the earthquake that caused it. It is classified on the Richter scale on which 9 is one of the highest levels ever achieved. This tsunami is one of the biggest ever, and unprepared for. The evacuation and warning systems for this tsunami were bad, not notifying people to evacuate on time. Due to this bad preparation, countries began making ways to detect seismic activity in places it occurs often.

The easiest, and most logical way to protect yourself from a tsunami is to reach higher ground, where the water cant reach you, of course to reach higher ground you need to have time. That means that people must be notified at least an hour before a tsunami to be able to flee. Now the question appears, how can we be warned before the tsunami? how do we know a tsunami is coming? Easy, that is where the seismograph comes in, a seismograph is a tool used for detecting seismic activity. Basically, a seismograph is a pen that is not moving that is writing on a roll of paper that is moving so that it accurately displays seismic activity. When seismographs are posted near shores they detect the incoming activity and the people can be notified.

Evacuation is also a method used for avoiding tsunamis. The way it works is that the media and news inform the people about the incoming threat, and tell them where to go and where they can be evacuated. When using this method there needs to be a good way of transferring the information to the people, radio, tv, telephone and other ways are used but nobody knows for sure if everyone will be informed. Even the people that do hear it may not hear it in time. A method used by the government often is sirens and loudspeakers. They set up speakers on poles so that in case of an emergency they can transfer a message through these sirens. These speakers have to be loud enough so that people could hear them though.

Although tsunami warning systems are not perfect, they do help a lot and without them the numbers of lives lost would be doubling, so they still do their job although when playing with peoples lives you can never do your job too good. Modern technology allows us to have seismograph stations at many coasts that communicate to help determine where the tsunami will strike, how strong it will be and many other important factors.People need to learn to take their warning more seriously, because if the people are prepared they can take a warning well. The people must know where to look for information, and must know where to go. Think about what would happen without the warning systems, tsunamis would obliterate everything and nobody would expect it.

All in all, tsunamis kill thousands and thousands of people every year, and our warning systems save the same amounts of numbers. With time out systems for helping those people are getting better but it is still a big issue. I believe seismographs are the best way of foreseeing tsunamis and if they were put in more places they would be a great help. Tsunamis are no joke and need to be taken seriously. the best way that people can get to safety before a tsunami hits and it is being used all around the world.

Natural disaster simulator. This game is really cool. Try the tsunami out and write your score in the comments.

Lab Reflection

In this lab we had the freedom to try out anything we wanted which allowed bigger discoveries and better observations. At first we observed the shapes of waves when they are uneffected by outside forces, they created circular shapes. When a barrier is put the wave stops in the line of the barrier but continues around the barrier also in a circular motion. A very interesting observation we made is that when a wave is powerful enough to take shape of the barrier, we first saw this when the waves came out as straight lines after encountering the barrier, to test our theory we used a long strip of curly clay too see if the wave would come out squiggly and it did. From this lab I can confidently say i learnt alot. I also really enjoyed this lab.

No Barriers

When conducting our tests with no barriers we saw that the wave travelled until it naturally lost all speed. We couldnt see if it would bounce of the edges of the pan because it was to week to get to the end.

When we tried with one barrier we saw that the wave got cut off in areas it was being blocked and continued on around it.
