What is noise pollution?

 what is noise pollution:
Noise pollution is a very, very loud noise that makes us irritated, stressed and distracting. It is very harmful to people and animals. That is way it is very important to learn how to protect ourselves. The noise is the product of modern civilization and industrialization.

cause and effect?

The examples for noise pollution are many: cars passing by, airplanes, traffic, horns, sirens, alarms, loud people, children playing, barking dogs, building constructions, factories, industries, etc. Every day we meet with noise pollution, but not every sound will harm us. In order to harm us, we need to be exposed to loud noise for quite a long period or be in the middle of a gun shoot or big explosion. For example, after a night in a disco club or a concert we will hear a whistle which a signal that we were exposed to noise pollution. Long exposure to noise can lead to hearing loss. Although in the beginning people are not aware of it the final phase is to become deaf. 

how do we measure noise pollution?

The noise is measured in decibels. For example, sounds that reach 60 decibels are the sounds of a normal conversation. A whisper would be 20 decibels. Everything that passes 70 decibels is irritating and can provoke damage to people’s health and you might even become death.

interesting facts abut noise pollution?

There are two types of noise, industrial and non-industrial noise. The industrial noise is the noise made by the factories, big machines, etc. The non-industrial noise is the traffic noise, concerts, people yelling, children playing in the park, did you now that sound travels even under water if sound can travel under water it means that even the oceans have sound pollution so fish are even annoyed by the sound and they can even feel it.

Noise pollution can provoke headache, stress, fatigue, insomnia, aggressiveness and physical problems. Noise pollution affects animals and children too. It makes them irritated and nervous. 

Not always the people thought of noise pollution as a problem. Nowadays, there are laws and methods of prevention. The laws suggest to build houses far away from highways, airports and stadiums. People who work in construction or factories should wear earplugs. The buildings can be protected with different types of isolation.

conclusion:

In conclusion, this is a very big problem in the world because it affects human and animal life. We can buy machinery that makes less noise and government could put some rules that in certain periods of a day workers should not work in order not to make more noise. There also should be some laws that protect children from noise. In my opinion, there should be more information about noise pollution. I believe that children in school should be educated about the causes and consequences of the noise pollution. It is important that the government raises awareness about this problem and do all they possibly can in order to protect people's health.

tuning fork lab

Tuning fork lab                       

Guiding Question: How does density of various solids affect the way the sound waves travel from the tuning fork?

Sophia hypothesis:i believe that if the surface is stronger the sound will be lower and if it is thin it will be louder.

Philipp’s hypothesis: Probably if the material is thicker it won’t vibrate that much. I think that solid will make a lower sound. Glass can vibrate better, because it is way thinner. That is why some people can break a glass by singing.

Exploration/plan&to do a test:

Materials:

• tuning fork
• locker
• board
• table
• wall

Procedure:

1) First we need to gather the materials we will need.
2) Second of all test and write down observations.
3) Thirdly we need record and analyze.
4) and then we will do the further inquiry.

Material                                     Density                                      Loudness

Locker	7.85 grams	highest
board	2.8 grams	low
table	0.75 grams	high
wall	3.12 grams	lowest

Analyses&data:

Philipp’s analyses: I figured out that it not always depends how thick or how thin an object is. For example the white board does not vibrate that much and the table makes a higher sound. I thought that the table will make a lower sound than the board but it was the opposite. Also the small tuning fork makes on the different objects sometimes higher and sometimes the lower sound.

Sophia's analysis:what i discovered is that there is a difference on the sound  and the materials of the object made  of,makes  a different sound in some thing it did not vibrate as much other materials.

Conclusion:

Philipp’s conclusion:I think that I learned a lot about sound and that I tested it good. It is interesting what the difference between to different objects is. Also the differences between the two tuning forks are interesting. Sometimes the smaller one is higher and sometimes the bigger one. This was funny and interesting. I liked to explore the density and loudness between objects.


Sophia's conclusion:i conclude that if the object density changes the loudness  of when it hits it. it depends of the object and what it is  made out of.



Further inquiry:

Philipp’s inquiry: I think that I learned a lot. I learned everything about sound and also explored it. I think a made a great job. In the class I worked a lot. This lab is maybe the best  I have ever made. In this lab i tested a lot of different materials and used the best ones.

further inquiry: i believe that doing  this lab i learned more abut more sound waves and how they travel  i tested a lot of different things and different materials (locker table).

summurie of what i learnd on sound section1

one of the most interesting thing that i learn  is that   sound can travel through solid,water and gas and i found out that there  is no sound on the moon i though there was i found that online it was a really interesting thing.and i learn that sound can go through a brick but that was kind of known but it can even travel through solid things that's why i am  saying that but it was really fun learning abute this.

Earthquake safety rules

Rules for home

One of the most important things to remember is (water safety kit and a blanket and some food) don't bring a large amount of it. The second most important thing to do is to move the bead from the window. If you have any pets they will probably start going crazy and bark. If somebody is cooking, try to remember to turn off the stove before evacuating. Stay in cover until the shaking stops. Stay calm and don't start going crazy. Keep a flash light beside bed and shoes to protect your feet . The flashlight should have fresh batteries because in these occasions the electricity runs out.for my home if you are in the top floor you need to go rushing down stairs open the door and go away or there is a door in the backyard you open it and you are already in the street and you would be safe you have to remember to move the bed and take heavy lamps from tables and take pictures from the walls or pictures that are in the wall of your room those are actually the things that are important.

Rules for shoppers 

If an earthquake occurs while you are shopping first stay calm don't rush into the exit doors (injuries occur when people panic and try to leave all at the same time through the same door). Stay away from windows. Another important thing: don't use elevators. The electricity will probably shut down. Stay away from heavy shelves or any shelves so nothing falls in your head. Try to move inside a wall, get under a table and cover your head. For evacuating don't carry anything that's heavy just carry your purse. If your purse is too heavy take things out of it. After the shaking go calmly out of the building and go somewhere out side and stay away from the building.

Rules for school

If an earthquake occurs and you are in school don't go crazy, stay calm and go under a desk and take everything there is on it. Stay away from shelves, hold on to the desk or to a leg of the table. Keep your head down until the shaking stops.
