Forces and Motion

The next unit that we will be working is forces and motion. I want to learn to learn pretty much about everything about it. I want to learn the basic and some advanced things. I don't want to learn anything specific just it in general.

Reflection On Everything

For this blog post we had to make a reflection about everything we did this year. The units that we studied are earths structure, minerals, volcanoes, rock cycle and mining. We learned about the earths structure and tectonic plated. tectonic plates are plates that are under use floating on the mantle so they are in constant motion. We also learned a little bit about the rock cycle and how it makes minerals. The next unit was mining were we learned the types of mining and the equipment needed to mine. Then we learned about volcanose and how they form and which types there are. For example one of the types is shield volcano. After that we learned about minerals which we learned a lot about. We learned what makes up rocks, the hardness scale which mosses invented, the types of minerals and how to identify them. As you see we learned a lot in science class and now we are leaning forces and motion. Below i will show you my plan that i made to make this blog post.

A group discussion + proposal

A group discussion + proposal

Group members- Ogi, Matija, Han &Ajda

Questions-

           Why are minerals important?

·       Because they use them for daily life purposes such as building materials, medicine and many more important uses

          What minerals are found in the world’s oceans?

·       Diamonds

·       Salt

·       Potassium

·       Magnesium.

·       Sand and Gravel.

·       Limestone and Gypsum.

·       Manganese Nodules.

·       Phosphoresces

·       Placer Gold

·       Tin

·       Titanium

Why are these minerals so valuable?

·       Because the process of getting them cost a lot of money

·       Because most of the diamonds lie on the continental shelf

          Who should have the right to receive them or the profits?

·       All countries around the specific ocean should have the right to own the minerals

·       The wealthy countries should share the minerals they find with the developing countries, but in return the developing countries should share their minerals

What are the problems with mining in the oceans?

·       It is very expensive

·       It causes earthquakes

·       They don’t have the tools to mine in some countries

·       Some countries are able to mine the minerals from the oceans but do not want to share them

Blue Questions-

Who owns the oceans minerals?

·       Mainly the countries around that part of the ocean

·       Everyone should share their profits/founds

What are the rights?

·       The people that find the minerals

·       The governments

·       Wealthy countries should produce the process and they should share it with the developing countries because they don’t have the privilege to afford it, but in return they need to give workers in return

·       By 2003, 157 nations had signed the law of the Sea treaty. The mining profits must be shared between all nations. Because of the treaty some nations think that everyone should share their technology and profits they get from the deposits

Do you agree with them?

·       Yes we do agree, because every country no matter if they are wealthy or developing should have the rights to have those minerals

The proposal-

Solve the problem without war-

·       We had some disagreements about what to write, because everyone had their own ideas but in the end we ended up voting to get the right proposal.

·       We also had many different answer possibilities so we ended up writing down more than one idea from more than one person

·       We should make a law saying that no matter who finds the minerals has the rights to keep them, no matter where it is

·       They should also share/trade what they find with the developing   countries    

·       The red writing is the highlights of our discussion or the disagreements that we had

·       The black is what we decided

Minning in Serbia

Today in class we discussed about the minerals that are mined in our home country. The most common minerals in Serbia are copper,lead,zinc and bauxite. The large part of the copper production comes from deposits in Timoc area ( Bor). Lead and zinc production mainly comes from Kopaonik area. Copper is the most mined mineral in Serbia. The process of mining copper includes blasting the ore with dynamite and then it is loaded in a truck to take it to the primary crushers, where the smelting process begins. Then it is crushed and chemicals are used to purify the copper ore, where the raw ore is separated from the fine sulfate of ore. The most well known company for mining copper is RTB Bor. Copper from Serbia is exported  to 150 key countries world wide. Copper is used in mass industry for production of various appliances.Copper isn't a very expensive mineral but it is useful.Our country is dependable on this mineral because it increases the overall profit of the country and it improves its economy.

Who Owns the World's ocean

This week in science class we talked about who own the oceans and the problems that occur when to comes to mining ocean minerals. the common problem is that wealthy industrial countries think that they could keep whole profit from mining because they paid for all the work. The poorer countries can not afford the process of mining the ocean floor because it is very expensive. There is a common sea law that 157 nation signed and according to this law ocean mineral deposits are the common property of all people. The problem is that wealthier nations   just don't want to co-operate with poorer countries because they are afraid that it would slow down their industrial production even though they should. In order to reassure poorer countries that they won't be left out, prospering nations should invest in the development of poor countries and also promise them the access to the annual percent of the mining profit. When it comes to who should get the annual profit, the countries that live near the ocean get the profit. The cities that live near the Pacific and Atlantic ocean should get some of the minerals.
