Copper in Serbia

Hello all. Today in science class we have to right a blog post about the most common mineral in my country which you can see is Serbia. I chose to talk about copper because its one of the most common minerals found in Serbia. Now how is copper mined? Copper is always found under the earths crust which means its subsurface mining.The biggest company that produces copper in Serbia is called RTB. The copper is exported to Americal along with some other countries but Serbia is keeping 33% of the mining area which gives a lot of copper. Copper is used for rooftops best against erosion, it is also used for wire in houses. In Serbia copper is especially valuable because the Serbs were one of the first ones to produce it and show it to the world. Copper is depended on in Serbia because you use this mineral for many many things such as wires in houses like I mentioned before. In conclusion Serbia is very rich on copper and it is the most common found mineral.

 Ocean Mining, is it a Big Problem

Hello guys I am going to talk you of what I have been doing in science class lately. So on Friday, April 8, Our teacher {Mrs. M} gave us a very problematic article to read, and so I did. The main Topic of this article was: Should the wealth be shared for ocean floored mining. After we read the text we are going to have to answer 3 questions and they will be right bellow along with my answer and opinion.

Indentify the Problem: The Problem about ocean floor mining is that not every country can afford to buy the necessary tools and technology needed to process this type of mining.

Analyze the Options : I think that the only options that the developing countries have are to somehow persuade the wealthy countries to help them and give them the money necessary to  process this kind of mining.

Find a Solution:  I think that the countries in the Pacific Ocean that should share their founds are Australia, and the island around it, with the east part of Russia as well as Asia and Japan {Japan really needs help right now.} The countries that should share minerals in North and south Atlantic are the following. Iceland and Greenland, Portugal, the east side of America and the west side of Africa. And all the countries around the Arctic ocean should share their fortune and minerals.

In conclusion I strongly  believe that the countries that can afford these types of things {tool} should share their wealth.

Mighty Mineral

Hey guys good to see you again :) in science class we are doing this project where we get to choose our own mineral to talk about it and answer a couple of questions. Down below are the questions

How do we get it out from nature?

Crystalline Structure: What does it look like? 

Abundance:  How much is found on Earth? 

Where is it found? 

Possible:  How valuable is it? How much does it cost?
We also had other questions that we needed to answer but on paper

My choice of a mineral was copper. While i was researching i found out many fascinating things about this mineral, For example one of the first cars ever invented were out of copper and not metal. I can not put on my slide show that i prepared for class with all of the questions answer so i am very sad, I will try though but i may not succeed. In conclusion i loved this project because i got to learn about this incredible mineral, I hope we do this again in future references

QUESTIONS
1.Does the density of a mineral depend on the size of the mineral sample?

Hypothesis:

It depends on how much air the mineral has inside.   It also depends on the mass divided by volume which equals the density.  To find the density you need to know the mass and volume.

Controlled variables:  How much water is in the graduated cylinder {we will keep this to see the difference between the minerals.} The scale.
Manipulated variables:  The minerals {we will test 3 different kind of minerals so they will have 3 different kind of densities.} 
Responding variables:  Density of the minerals 
Materials:

1. Balance
2. Graduated cylinder
3. Weighting paper
4. Samples of minerals

Procedure: 
1. Choose the 2 minerals, 3 samples each.

• WHITE FELDSPAR
• ORANGE FELDSPAR

2. Find the mass

• 1. orange feldspar 23.6
• 2. orange feldspar 34.3
• 3. orange feldspar 18.6

• 1. white feldspar 32.1
• 2. white feldspar 21
• white feldspar 31.5

3. Find the volume

• 1.orange feldspar 22 ml
• 2.orange feldspar 25 ml
• 3.orange feldspar 14 ml

• 1. white feldspar 28 ml
• 2. white feldspar 12 ml
• 3. white feldspar 20 ml

4. Find the Density
Orange feldspar
1.072
1.3
1.328
White feldspar 
1.146
1.75
1.575

5. Make a table with what the density,volume and mass are



Data analysis 
In the data above i personally can see multiple patterns. The first pattern i see is that the volume is always a little bit smaller then the mass this is maybe because there isn't so much space inside the mineral as much there is mass. The second pattern i see is that there are minerals which have quite the same volume as well as the mass

Conclusion
Does the density of a mineral depend on the size of the mineral sample?  Well from what i have seen in our lab report is that the bigger minerals or the larger ones have more volume and mass then the smaller ones, therefore they it has more density {this is because mass/volume=density.} So I will have to say yes

Further inquiry
If I were to do this whole lab again i would have changed our samples to find a lot of differences in the mass and volume so they would be completely different. I would have also prefered to work in a quite place so i would get distracted. Other then that my group was amazing i could have picked a better group because they started working at once, they didn't argue, and the best of all they were always on track.

Minerals

In science class we have started learning about minerals and these where some of the questsions we had to answer
How are minerals formed?
Can rocks be mirnerals?
and many more
One of the most precious minerals to me are diamond not only are they beautiful and stuff but they are the hardest and most worthy mineral ever. What people don't know about diamond are that there are so many of them but its hard to get to them that's why they cost insane {too much.} Our upcoming test which is next week is about mirerals so if anyone has some valuable information please share it with me
HOPE YOU ENJOYED!! 

What is a mineral

In science class today we studied about minerals and we found out that minerals are solid, naturally occurring, inorganic, fixed composition, cyristal form. We also found out that the hardest mineral is a diamond and the softest it talc. One thing that could help you on a test {which will help me next week} is these questions that will help you figure out if the object is a mineral or a non mineral

• Is it non-living
• Is it a solid
• is it formed in the nature
• does it have a crystalline strugture                                                                                             HOPED YOU ENJOYED AND THAT I HELPED YOU ON A TEST :D

Volcano Presentation

This week in science class we have been working on volcanoes and had to do a presentation about a volcano or in our case two different volcano but in the same volcanic region. We choose to do the volcanoes Poas and Arenal which are located in Costa Rica. While we were researching we saw that there is a river which connects Poas to arenal. If i where to have listen to our {my and my friends presentation} as a teacher i would put the grade 5 from 6 because we had pictures we had slides and we talk about what we though of the volcano. I learned that my Poas volcano has a good and bad side because it can heal people form diseases but i also produces acid rain. Volcanoes are really fun to learn about because every volcano has a different shape or look its not all the same.
HOPE YOU ENJOYED MY PARAGRAPH!
