Noise Pollution

What is it?Noise pollution is annoying and potentially harmful environmental noise.It is unpleasant and harmful. It can also be a unwanted disturbance around which can damage your ear if it is really loud. Noise travels around and you can't get rid of it or run away from it. Noise pollution is performed by dog barking, trains, loud music,cars or motorcycles and even more. There is different types of energy pollutions. For example two of them are: Light Pollution and Heat Pollution.


How does it affect to our ears?It can damage the health and hearing, which could conclude to loss of hearing. This affects around 1 million. Escaping sound is impossible. You can just close your ears. There are many other causes that can happen from sound. Sound pollution can avoid you from sleeping can give headaches and annoy you. It can also increase your blood pressure, which is not good.


Ways to eliminate sound or get protected?One way of protecting yourself is to put ear plugs, don't live in a house close to crowded places, for example the airport, train station etc. If you do live you have special walls or material in the house that can protect you. Some people uses this. Most people have neighbors and if you open loud music, maybe in a party or celebration you should turn the music, down so they don't get disturbed.


How is science/technology involved in solving these problems? There are special systems for blocking sound and different noises. For example special walls that protect your ears. There are also earphones which help you hear better, if you have problems with hearing. There is one problem that science can't solve is that bring the hearing back, because it is really hard after you lose that sense. It is kind of impossible.

Seismograph Lab

Design a Seismograph Lab

Discovery of reaction to the weight when the wave is added

Kyle C., Philipp G., Luka L., Ergi K.

2/7/2011

Objective: Find the reaction of the wave (seismograph) when the weight attached

I.  GUIDING QUESTION/S:  
What will occur when different weights are added to the surface wave (Finding the work of seismographs)?

II.HYPOTHESIS:
Kyle: I believe that depending on which or how much the weight, the solution of the balance will vary.
Lukas Hypothesis: I Think that the balance will if we differ if you add more or less weight.
Philipp: I think if we change the weight it will swing different. I think if it gets more weight it will swing bigger.

III.  Exploration (PLAN & DO A TEST):

Materials:

Previous Fail Trial Materials:

Red Pen
Blue Pen
Chicken Wire
Scissors
Board Game for the bottom
Tape
Wagon Wood Wheel
Paper
Weight
String

New Trial Materials:

Pen
Weight
Tape
Paper
Ruler
Science Discovery Book
Chicken Wire
Table (As an earthquake)

Procedure (New Seismograph Procedure):

(After Gathering the Materials above)

1. First attach/tape the tip of 2 rulers to the wall horizontally and parallel
2. By using the tap attach the chicken wire to the rulers.
3. Then connect the pen to the wire, which holds the weight. (The objective is to see, if adding weight will affect the result )
4. The pen should be stationary; the pen will be producing seismogram.
5. When the pen with weight is connected with the rulers, slowly prepare the papers and the table to produce earthquake (magnitude).
6. Let one person move the paper slowly when one or two shakes and create earthquake movements.
7. As a result, the seismogram will show the wave vibrations.


IV.  RECORD & ANALYZE

Successful attempt

          

Data of Seismogram Analysis:
                     


Kyle’s Analysis of the Seismogram:

The Graph shown above shows our final data of the new seismograph we made. As the seismograph reacted by the magnitude of the table, the wavelength and the frequency of the seismogram altered. The monitor up there shows how fast and how hard the magnitude reacted. In final consideration, the new seismograph we made was efficient, simple, and easy. I had discover that the seismogram will show difference results when depending on the weight; as more weights are included the shorter the wavelength will be and faster the vibration or the movement.

C.  Analysis of Data:

Kyle’s Analysis: I had figured out that the result and the affect of the wave movements will alter depending on how many weights are added to the pen.

Philipp’s Analysis: I figured out that if there is more weight on the pen then the pen will swing worse and smaller. We had the problem that we put the weight next to the pen and not over it. That’s why the first try was not working.(The weight was pulling the pen to the side where it was attached)

Lukas Analysis: I found out that if we add more weights to the pen it will swing less than the pen without weights. We had problems with the weight positioning. That gave us some dificulties.

IV.  Concept Acquisition (CONCLUSION):  

Kyle’s Conclusion: There are several conclusions to write down; mistakes and trials were made throughout the tests, some were successful but majorities weren’t. As our class started the seismograph lab, my group partners had left without a sign. Though this wasn’t the major problem it could had caused a huge impact. But the problem of this lab was that many attempts were made, however not a single we expected came out. All of us had discovered that the pen should had been stationary, if not we had to adjust the box (it was arduous to adjust since the box was about to be ripped). As my group mates knew this matter, we needed support or a change, we lost control when we were trying to aim higher.

Philipp’s Conclusion: I think that we had a lot of problems with the seismograph lab. We tried to fix up things, we can’t fix up. We also had the problem that we were sick and couldn’t come to school. We were trying ti finish it but our seismograph did not want to work. We finished our writing part very fast but we could not build the seismograph. After all we our teacher helped us and gave us a good idea and we build a good seismograph. I think that it was still fun to make our own seismograph. I think our last try of the seismograph worked pretty good. Our mistakes were that we tried to make the seismograph with to pens. After that the whole seismograph broke. That was the end of our idea. I think an
improvement was our second seismograph because it worked very good.

Lukas Conclusion: I think that we

V.  Concept Application (FURTHER INQUIRY):    

Listening to Sounds Lab

Purpose: to determine a way to amplify sound travelling to your ear

Procedure:
1. Tie 2 strings to the handle of a metal spoon. Each string should be about 40 cm long.
2.Hold one end of each string each hand.Bump the bowl of the spoon against a desk or hard, solid object. Listen to sound.
3.Now wrap the ends of the string around your fingers.
4.Put your index fingers up against ears and bump the spoon against the object again.

Conclusion:
1. How does the first sound compare with the sound you heard with your fingers up against your ears?
The vibration was stronger. It made it deeper.
2.How did the sound travel to your ears when you had the string touching your ears?
Because the sound was travelling through the string and than came to my ear.
3.Why do you think it was easier to hear the sound when you put the strings by your ear?
We tightened the string and that made us hear it easier.

Properties of Sound Lab

Experiment 1

Distance away from middle	Description of sound
1 cm	deep
2 cm	slightly deep
3 cm	medium
4 cm	higher
5 cm	highest

Experiment 2

Thickness of Rubber Band	Description of sound
Thick	Low drum
Thin	Higher drum

Tightness of Rubber Band	Description of sound
Loose	light
Tight	lighter
Tightest	lightest

Length of rubber band	Description of sound
Longest	deep
Long	slightly
Shortest	light

Conclusion Questions:

1.How did the sound change when you changed the amplitude (how far the rubber band was away from the middle point)?

When the rubber band was close it the sound was light. When it was far the sound was deep.

2.What happened when you changed the thickness, length, and tightness of the rubber band?.Sally is playing the guitar and notices that one of her strings is flat (pitch is too low). What can she do to fix it?

When the rubber band was thicker it made a deeper, sound. When it was thin it barely made a light sound.

3.Sally is playing the guitar and notices that one of her strings is flat(pitch is too low). What can she do to fix this?

She can make it tighter and pull the string, so the sound is better.

Earthquake Protection

Earthquake Safety Plan For My Home


I think the best way for my family to protect and survive in a big earthquake in our house is to go under the
big table in the living room because it's hard and i think it will be safe enough.Perhaps if the wall falls down it can fall on you and you die or get injured. Another way of protection that could be used in my house against earthquakes is to get under the door because it's strong and is a different material than the rest of the house.  You must cover yourself with a table,by going under the table. and then you keep your head down until the shaking stops for safety. To make my home earthquake friendly we should move some windows because there is quite a lot amount of windows. If there is an earthquake, it can brake the windows and they can fall inside. That could make a serious injury. Another problem is the Television. It might fall and brake and that could make smoke.
Drop,Cover and Hold!!
