Forces + motion KWL

   I know a little about forces, the only thing is gravity I know about. Gravity is the force that makes things rise and fall. Some examples of gravity are people, if there wasn't gravity we would not be able to return to the ground when jump. Another example where gravity is kind of mean, when we drop things on accident that drop to the ground and breaks, and when that happens parents yell at us. It would be more peace on this world if gravity would keep these objects in the air and we could put hem back on place.
    Motion is the way things move. Sometimes motion can go crazy, and we get dizzy. For example on some crazy rides we get sick of the speed and the direction the ride is taking us. But, motion is important for the world because if it wouldn't exist nothing would be able to move.
      

Things that I want to learn is mostly related to forces.
1: Without gravity would we excist?
2: What are other forces?
3: Is punching a force?
I have only one question about motion
Is motion controlling space too?

How valuable is a rock reflection

   During this unit we learned mostly about minerals. This is related to our unit question because minerals are a type of rock. This topic fits in our area of interaction because minerals are being mined in mines, and they are on the Earth's crust. For this unit I mostly understood everything. I think that because when we did projects and labs I understood everything that was asked.  I would like to know more about a topic we did only a bit and that is the rock cycle.
   Throughout this unit I think I did well. I think that, because all my assignments I did with lots of effort. The only thing I could improve is to add details to my Mighty Minerals for giving the properties of my chosen mineral. In this unit we did activities which I found interesting. The only new thing which I learned to do is making GoAnimate and Bubbl.us.
    For me the Mighty Minerals project was amusing because it's exciting learning everything about a certain mineral. The least favorite activity for me was when we had to answer all different questions while our teacher Mrs. Medenica was absent.
       If I could add something for the next year's 6 graders it would be maybe a movie about the minerals.  

Reflection on Debate

          SCIENCE

• Magnesium, salt, copper, nickel, titanium, tin and iron ore.
• They are used to make crude oil and very rare.
• The countries closest to the oceans and the countries that have the biggest needs. The countries closest to the minerals should export them to countries in need if those countries are far away from the ocean.
• That in mining in the ocean they use oil and so they pollute the ocean and kill marine life. Also when fish get diseases they might be caught by people and then eaten, so the diseases might get on land.
• Mostly the neighbouring countries of the ocean
• They have the rights to mine in the ocean but only with permission of the leaders.
• Elena does because we need them for a daily life. Stefan does because we need them and are beautiful. Sofia does not agree because we are polluting the ocean and can get some of the minerals not out of the ocean. `Sofia believes that just because there are places in the world that are not polluted doesn't mean we have to pollute them.

We think that people should use less pollutable materials when extracting minerals from the ocean. Try to cover up the holes they dug and be a lot more careful when extracting the minerals.

During this debate, I found out what I already have written on the blog post about Who Owns the ocean's minerals. Our group didn't have many disagreements or conflicts. We discussed calmly our opinions on questions.  In my group I was the discussion director, Elena was the writer and the reporter and Sofia was the time keeper. Although, we all discussed our opinions.   

Who Owns the World's Oceans

WHO OWNS THE WORLD'S OCEANS AND ITS RESOURCES?



There are many resources which are not renewable and which we are going to spent completely and be left without them. So, there is a constant effort to find new sources. The scientists found out that the bottom of oceans are rich with useful deposits of minerals, oil, gas and other resources that humans need in their everyday life. This is how the exploitation of under-ocean wealth started.


However, who owns the oceans and their resources? The international law says that coastal countries, which have borders with oceans, have the right to exploit everything from the ocean 12 miles from their coast. In some cases, these countries have the right to use resources from the continental shelf which stretches from their territory under the ocean. However, this is only a narrow part of the ocean floor. What about the huge; mid-ocean floor which does not belong to any country's territory? The law says that the oceans belong to everybody and that we can all take benefit from them, if we are able to do that and if we know how to do it.



The problem is that mining minerals from the ocean's floor is very complicated and it requires new, expensive technologies which most of the countries can not afford and don't have. This means that only the richest and the most developed countries can get to the ocean's resources and use the ocean's minerals, oil and gas. This is not right, because everybody should have the right to use them. Undeveloped, poor countries would like to use part of these resources, as well, and they say that the rich countries should share this ocean's wealth with them! Of course, wealthy countries which invest  lot of money in these projects don't see why should they share the profit, if they did all the work and spent all the money. This is a big international problem these days.




I think that I have an idea how to solve this dispute. I think that United Nations, as independent organization of all the countries should be in charge of all the Ocean's floor mining and exploitation. Each country would invest as much as it can and in this way a lot of money would be collected. All that money would be given to one, independent UN company which would develop necessary technology and which would be the only one to mine the ocean floor. Everything which would be collected from the Ocean's floor would be distributed evenly to all the countries of the World. This seems fair to me and I hope that the World will be able to agree how to use the Ocean's resources.

Mining in my home country

   My home country is Serbia, and it's not very rich in mining, It has only two mines,Rudna Glava and Senjski Rudnik.  Rudna Glava ( ore head) is located in eastern part of Serbia.  It is one of the first evidence of European copper mining.  It belongs to Vinca culture, which was an ancient culture.
 Senjski Rudnik is a village which has a mine in it. It is a coal mine which was established in 1853. In 2010, it turned into an open-air museum.
     The most mined mineral in Serbia is Bentonite, it is a type of clay, and it has many uses such as for making sculptures. We mine it with ashes, or a special machine for digging.
     Another popular mineral that is mined in Serbia is copper ore. It is a popular in the whole world. In Serbia, the miners mine it with with a large machine in a shape of a capsule.
