Buoy Data Reflection

For science class we have been looking at a link that shows us all the buoys that are located in the world. On these buoys you can see a lot of information. You can see what the buoy looks like, see the high the waves are there, and some other things such as the atmospheric pressure. During the time that I am looking at this, near England there are waves that are as high as 20 feet! But near America it said that the waves were not that big because I checked a lot of Buoy’s data, and they said that they were around 3-6 feet tall.

There are a few types of buoys. There are types that record all the data, but also there are types that show boats which way to go.

The yellow buoy is a type that records all the data, such as winds, height’s of waves, and other things like that, but the green type is the one that shows boats which way to go, mostly because there are big rocks in nearby areas, so that means that they should go left or right of the buoy depending of their color.

The atmospheric pressure at this point is 34.70 and is rising, while in other areas it is lower. I think this is determined by the height of the wave because the bigger the wave the bigger the atmospheric pressure. I am not sure about this because in the USA I cannot find a single buoy that shows the height of the waves but they show the wind and the atmospheric pressure.

I think that tsunamis and hurricanes make the waves go higher because tsunamis are big waves, and hurricanes have a lot of wind causing them to make bigger waves. I think that wind is also a key thing, because it’s the thing that pushes the water, causing waves, and it also determines the atmospheric pressure.

I think they are helpful because they can indicate when a tsunami or hurricane will happen, and they could evacuate the city if necessary. Like this they could save thousands of lives, rather than having to make a whole new graveyard.

Dolphins Current Event

Ever since Scientists realized how smart dolphins are, they have began trying to speak with these mammals. In these past few years scientist tried countless ways of communicating with dolphins, they even once gave them IPad's to use. But now they have come up with another brilliant idea. They call it the "Dolphin Speaker". This machine will not only be able to hear the low frequency clicks, but also the high frequency clicks that us humans cannot hear. This has never been possible, until now. Once they have recorded all of their sounds, they are going to replay it to them and see how they respond to those clicks, squeals and whistle. Even though we are still trying to figure out what these smart animals are trying to say, they have been quite successful in trying to learn some basic elements of human language and they can even follow these instructions when they are delivered on television.

 I think that dolphins are very smart animals. And I think that we are going to learn their language fairly soon because with this machine it will be easy to record their clicks. And then when we play it to them, we will see by their reactions if it’s true what the machine is telling us. And as you can see, in some way they are a bit smarter than us, because they have learned our language (not how to speak it, but understand it) but we haven’t even learned how to undersand or speak their language unless we are making random noises that sound like theirs.

Designed Lab Report

For our wave properties lab, we will be using droppers.

Guiding Question:

How does weight of an object affect the waves around it?

Hypothesis:
I think that the shape does not matter. But I think that the weight is going to determine how high the waves are going to be. Also I think that the height the object is dropped from will determine the height of the wave.


Materials:
1) Bucket
2) Water supply
3) Camera
4) Ruler
5) Varied Objects-
->Plastic balls
->Clay block
->Tape roll
->Big  rock


Controls (what stays the same):

1) Amount of water in bucket before  
2) Size of bucket


Variables (what changes):

1)  The objects
2) The corresponding waves  




Weights:


Plastic Ball 1-  57.2 Grams
Plastic Ball 2-  5.1 Grams
Modeling Clay- 85.4 Grams
Tennis Ball- 66.8 Grams
Styrofoam Ball- 12.8 Grams  
Tape Roll- 71.3 Grams

Shape:

Plastic Ball 1 and 2- Sphere

Tape roll- Spherical/2d circle  


Results:

Tennis Ball-

Plastic Ball 1-
Splash: 5 mm
Plastic Ball 2-  
Splash: 1 mm
Styrofoam Ball-
Splash: 1.5 cm
Tape Roll-
Splash: 2.5 cm
Clay Cylinder-
Splash: 1 cm
Clay Flat circle:
Splash: 4 cm

Data Analysis:

I think that my data was accurate because we tested each thing twice, and if we got different answers, we would try it a third time to check which one was correct. I saw that there was a pattern that showed that the heavier and bigger objects made the bigger splash. Even though we only droped the objects from 30 cm height, I think that if we dropped it from a higher point it would have made a bigger splash.

Conclusion:

How does weight of an object affect the waves around it? Well we thought that the shape does not matter. But I think that the weight is going to determine how high the waves are going to be. Also I think that the height the object is dropped from will determine the height of the wave. What I predicted was going to happen or my hypothesis was close with what actually happened during this Lab report me and my partner designed.

Further Inqaury: We had a few problems with our plab report when we started. First of all, we couldn't decide on the topic we were going to write about. Once we solved that problems, got all the materials, we had to put it all together. Once we did that, we had a ruler sticked next to the tank in wich water was filled up. And once we would throw the object into the pool, by instinct we closed our eyes because of the water splashing. So for some objects we needed to throw the object a few times until we got it right. I think we could have made it that we throw the objects from different hights, but we didn't because we had little time to complete the throwing in time to be able to finish the writing part.

Tsunamis and Earthquakes

For science class we had to learn about one of the following: Earthquackes, tsunamies, and hurricanes, and then write an essay about them which is about 600-2,000 words. For my essay I chouse to write about tsunamies. Tsunamies can be different. Some can make damage, and some can only make a liitle water on the streets.

Tsunamis are waves that are created by oceans or other bodies of water, by eaarthquakers, landslides, volcanic eruptions or meteorite impact. The can make huge destructions when they reach and hit the coastlines. Tsunamies can travel very fast, as much as up to 700 miles per hour, but they are only about one meter high in the open ocean. But when they get to the coasline they can be a series of waves up to 30 meters high! The tsunamies mostly occur, when the tectonic plates colide, and when one plate goes up, it makes a big seismic wave, like we did with our lab, but just from underneath, and a lot bogger. The tsunami isn’t that high in the ocean, its only about one meter, and if a ship goes over it , it probably wouldn’t even feel it. But as it gets closer to the coastline, it gets bigger. It lifts the wave up, but it doesn’t break on the beech, it becomes a monut of water that floods the place, and can destroy a lot of things, and kill a lot of people as we saw in Indonesioa in 2004 and in Japan in 2011. Around 80% of all the tsunamies that happen on earth are in the Pacific Ocean. Most offenly they are occurred at the borders of the Pacific ocean and the Ring of Fire. This is because at the Ring of Fire 90% of the worlds earthquackes happen there, and they are whatmostly cause the tsunamies to occur. The tsunamies damage can be huge. Once the tsunami floods the city, it can continue to cause damage for weeks. It can cause a lot of damage such as death, injuries, millions of dollars in financial loss and a lot more. The effects are actually continued for many years after the natural disaster hit the city.`Tsunamies are predicted by a siesmometor. When this machine detects a earthquake under the ocean, it signals the coaslikes the tsunami could head for. But the machine is not perfect, because not all earthquackes make tsunamies, but its always better to get away just in case if the tsunami is really going to happen in their area, or other areas. After an earthquake occurred in a certain area, you must calculate the energy of this earthquake. From the seismograph, you can collect data from this earthquake. Like this, you can calculate the location, depth and strength.What is good about this is that it can reveal clues about the nature of the rocks the waves were passing. The data records the motion of the mass. This makes a series of squiggly lines, that look like waves we have done in class.For big tsunamies, there is only one benefit, which is economical. Imagine if you have a house that you need to destroy, and there is a big tsunami coming, it would be good if that house was torn apart and took into the sea. This would be good for the government because they wouldn’t have to pay money to destroy that house or building, because the tsunami did it for them, but it would be bad for the environment because it would pollute the environment. 
In 2004, an earthquake occurred in Indonesia that was marked 8.8 in the richter scale. And only a few minutes later a big tsunami hit the same area. This made big damages to the city. It also killed a lot of people. To be percice, it was around quorter of a million people that died during this time. Something similar happened in Japan last year in 2011 whan a big earthquake also happened which was also around 8.8 on the richter scale. It aslo followed with a big tsunami wave. This also killed a lot of people. But wats worse, it also damaged a nuclearactive power plant that made equipment failures, nuclear meltdowns, and release of nuclearactive materials in Fukushima.
