KWL---Forces & Motion

Hey all, and welcome to my 37th blog post this year! I have exiting news for you! We are starting a new unit! Exiting right? Well, I am exited too because if I tell the truth I was getting bored with writing all those reflection and blog posts about minerals although I did learn TONS! Well, this next unit is all about forces and motion! So the key “phrase” of word that we got is KWL, which means, Know, Want to know and learn! Of course I can only answer the first two today, because I didn’t learn anything yet!

Here is what I know. I don’t know very much, but this is what I know, or what I heard my classmates say in class:
• A type of force is gravity
• The world is always in motion. For example: the earth resolves around the sun.
• We humans are also always in motion. We walk, we run, we talk, we breath, we eat and so on. Those are all motion.

That is pretty much all that I know!

What I want to know:
• How would you define forces and motion?
• Do force and motion affect our lives?
• How do they help us?
• Do we depend on motion and force? Why?
There is many more, I could go on for ages, but those are the main ones. Please if you are a pro, answer one of these questions, I would really appreciate it! Towards the end of the unit I will add something to learn and know, and take away from what I want to know! Thanks! See you soon!

Earth's Inner Secrets Unit Reflection

Hey people! I’m here with you again, for the 34th time this year and I will tell you everything about what we have been studying for the past couple of months. We have been working on the Earths Inner Secrets. Plate tectonics, volcanoes, minerals and mining are all part of inner Earth. You read all of my blog posts about those things BUT this is like the big picture. The final copy, the reflection of the whole unit! Awesome huh? Now, please let me guide you into my world…

So you know how the humans discovered everything that we have right now and stuff but like have you ever thought about the other things that we STILL don’t know? We think that everything we have is totally clear to us and that there are no more secrets in what we discovered so far. But now I need to tell you something really mean. You are wrong. We might know everything about how cars affect the environment or what a human body is made up of but how about the earth? What is inside the earth? That is one big fat question that we have no answer too. We can only predict. I will bet you anything you want if you could live me a list of at least one person who knows what the earth is like inside. No one knows and no one can predict without having to stop what they are doing, focusing on the questions, and taking a few minutes to think before answering it!

We have found many things inside the earth. I mean you probably know that the earth has 5 layers. The crust (its like the ground we walk on), upper and lower mantle (hot, moving magma), and outer core (a liquid that is getting harder) and of course the inner core which is made out of solid IRON! Pretty cool huh?

Another thing that we are genies at knowing are minerals. As you were Reading my older blog posts you might have noticed that we have done lots with them. Some minerals are created deep under the earth where hot magma cools which causes minerals such as diamonds to create! Amazing! These minerals are called Igneous. (Rocks formed by the cooling of molten materials. Igneous rocks can form beneath the earth’s surface, or at its surface, as lava.) How do we get minerals such as diamonds out of our earth??? How about VOLCANOES! Some people are pretty sure that volcanoes are like a secret opening into the deep secrets of our earth, a passage that leads way down into the burning mantle! The problem is that we can’t send machines or humans down the “secret passage” because they would get burned from such a high temperature! Even though there are different types of volcanoes; Shield Volcanoes, Cinder Cone volcanoes, and Composite Volcanoes, but they are all burning hot if you enter the “secret passage”. So my advice, don’t ENTER!




While studying minerals Ms. M (our amazing science teacher) thought us a simple way of identifying a mineral. The word “SNIFC” is what you should always think about when you are about to identify a mineral. S as in Solid, N as in Naturally Occurring, I as in Inorganic, F as in Fixed Composition and S as in Crystalline structure! So lest take gold for instance to check if it’s a mineral. So is it solid? Yes. Is it naturally occurring? Yes. Is it Inorganic? Yes. Does it have a fixed composition? Yes, and does it have a crystalline structure? YES! You just figured out that gold is a mineral! Good work buddy!

Now, we covered lots of things int his blog post but there is one more thing that I want you to remember! And that is………..MINING! Mining is when like you get those really big and heavy machines and then you like dig from under the earths surface or very close to it. Ya that probably it….and I am telling you, you are correct! That is mining! Of course now you might be thinking, “Oh, I’m gonna safe some of my money get the big heavy machine and dig out some gold, or diamonds pack up and leave!” Well its not at all that easy! If people were thinking that way, then everyone would dig out what they wanted and leave a big mess behind. Well the world would be one big garbage can I tell you. So, what I am trying to get into your intelligent brain is that even such an easy sounding job like mining has RULES!


OK, before when I was talking about mining and stuff, I said it was the last thing that I was gonna talk to you about I kind of, more or less, 99% …………LIED! There is one tiny tinny thing that I want to talk to you about before I wrap up this blog post. Well rocks. While you are sitting in this beautiful world you might have noticed that we have many rocks on this planet! Rocks are very common you might be thinking right now. Well there are 3 types of rocks; Igneous rock, which is made when magma/lava cools and hardens, sedimentary (made up of sediments that joined and compressed together), and metamorphic (rocks that were once sedimentary or igneous and transformed into something else). So see! That was pretty cool huh? Now I want you to know another tiny detail! Rocks are actually made out of MINERALS! Can you see the connection? Its like a cycle! Pretty cool huh?

Thanks, for joining me in this awfully long blog post, but I hope that I have refreshed your brain and that know you know everything about out unit! Thanks again! Hope you have a good night rest cause this was pretty tiring! See ya!

Group Descussion

Hey all! Today I will not teach you anything but I will show and tell you how our class works. So today our teacher separated us into groups of 4 and gave us the same questions to answer as we had to do on our own for our blog post. As we were working together I saw some great ideas and I hope that you enjoy this blog post!

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.
•Phosphorescent
•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


Reflection-
Today when we were working all really worried about our grades I saw some really interesting points of view. I totally understand and agree that each person thinks differently but also I saw about 3 people were thinking the same way as me. It is very interesting observing and seeing how completely different people, who don't work together in the same group come up with the same answer or proposal in this case. Over all I think that our group worked well and was pretty organized. We didn't have any trouble picking roles so I think it was well done! I love the activity and I hope to do it again!
Please feel free to leave any comments for me!

Slovenias Most Common Mineral---Zinc

Hey all! Today I am going to tell you all about Slovenia's most common mineral--- lead! That is the most common mineral in Slovenia besides gold. I am going to answer the following questions about the mineral in Slovenia, but I can not guarantee that I will answer all of them about the mineral, because some were not answered. Anyway the questions are-

-How is it mined?
-Who is the mining company?
-Where do the materials go-are they exported to other countries to factories?
-What are they used for?
-Is it valuable?
-Does your country depend on these minerals being mined?
-If so, why?

About the Mineral-
Zinc
Chemical Formula- Fn
Color- White to blue gray
Streak- Light gray
Transparency- Opaque
Luster- Metallic
Cleavage- Perfect in one direction
Hardness- 2
Density- 6.9 – 7.2
Crystal Shape- Hexagonal



How is it mined?
Zinc ore is mined using underground and surface mining or a combination of both. The Mežica Lead and Zinc Mine is famous for mining zinc. The mine is closed now. After the ore is mined, they do something called flash smelting where they heat up the ore until it makes zinc oxide (zinc + oxygen). The zinc ends up as powder.

What is Zinc used for?
Zinc is used in paints, for coating steel, automotive parts, electrical fuses, batteries, roof gutters, pennies, rubber, deodorant, and much more. Pennies are made of zinc covered with copper. Zinc is needed by animals and humans to stay healthy. Scientists are worried about the amount of zinc that is being used in industry because it ends up being dumped into bodies of water as waste. When this happens, fish that live in it, or people who end up drinking it, can be seriously hurt by it.

What are the mining company’s?
I did not find any companies online, but I did find some mines from Slovenia where they get Zinc.
-Breg is a settlement in the hills to the south of Mežica in the Carinthia region in northern Slovenia.
-Cave del Predil is a hamlet in the Friuli-Venezia Giulia region of northeast Italy. It is a frazione of the comune of Tarvisio in the Province of Udine, located 15 km south of Tarvisio, near the Italian-Austrian-Slovenian border. Until World War I, it was part of Austria-Hungary, and then came under Italian control. It is known for its former lead and zinc mine, which operated until 1991. A tunnel, originally used for water drainage and then for transport of miners and political refugees escaping from Communist Yugoslavia, connects it with Log pod Mangartom, Slovenia.
-Mežica is a town and a municipality in northern Slovenia. It lies on the Meža River in the traditional Slovenian province of Carinthia) near the Austrian border. The town developed close to a lead and zinc mine under Mount Peca. Mining began in 1665 and ended in 1994. Today the mine is only open for tourist visits.

Where do the materials go-are they exported to other countries to factories?
I didn't find a lot of information about this questions, but I did find the amount of money that we get with the exporting and how much money we recienve when we export.

In 1998:

GDP—real growth rate: 3.6%
Total Slovenia exports: €9.2 billion
Total Slovenia imports: €9.9 billion

Is it valuable?
No, zinc is not very valuable.

Does your country depend on these minerals being mined?
Slovenia exports lots of other minerals such as; aluminum, lead, gold, gypsum and many more but it exports lots of other things too so i wouldn't really say its going to become poor and starve to extinction. So it doesn't really urgently depend on it but zinc has some affect on it.

Conclusion-
When you think of the tiny country named Slovenia, which minerals do you think of?
I'm guessing probably not zinc ha! Well zinc is one of the most common minerals in Slovenia! It is not the only mineral there is many more, but it is one of the most commonly exported minerals although Slovenia mostly exports fruit, and other food such as salt. It surely does export minerals but they are a bit rare for us to export since we aren't so noticeable and we don't have such a big amount of it. I hope that you have learned something new about my home country Slovenia and it's minerals! Thank you, and I hope to see you soon in my next blog post! Please feel free to add a comment beneath this blog post for any improvement or suggestions! Thanks!

Who Owns The World's Ocean's Minerals?

Hey all! Today I will teach you all about the oceans minerals and who owns them. A while ago my teacher Miss M. told us about this amazingly interesting topic, and supported her idea with some cool and and interesting websites, that helped me and my class mates to finish this project, while learning lots of new bits of information. When it comes to the question "Who Owns The World's Ocean's Minerals?" we really need to think hard. As I scanned through a couple of websites I found a few interesting opinions, and facts about "Who Owns The World's Ocean's Minerals?". Some supported my idea which I will state later. Now I will share a few notes that I took during researching this exiting topic. Feel free to leave any comments or questions while you are reading this blog post. Thank you, and begin learning!

Who Owns The World's Oceans Minerals?
-Rich Mineral Deposits lie on and just beneath the ocean floor
-Costal Nations have the right to mine near their shores
-Minerals that are hidden beneath the oceans floor are open to all Nations to mine
-Today minerals are also being mined form the continental shelf

WHO OWNS THE OCEAN'S?
-The 5 oceans are actually one big ocean, so not divided
-Every person on this planet owns the ocean, but at the same times we don’t
- Countries around the world agreed that none own the ocean

WHO CARES ABOUT WHO OWNS THE OCEANS?
- At the end of 1960’s about 400 million tons of oil were removed from the ocean PER year
- Some for the oil and gas that was found in the ocean is now polluting it
-Countries who fish in the ocean can send their boats to fish anywhere around the world


WHO OWNS MINERAL RIGHTS?
-In most of the nations around the world the minerals found or digged go to the government, without noticing who owns the land
-The owner of the land can sell the mineral rights to another nation
-The rights of minerals on bought land belongs to the sovereign who owns the surface permanently

What is THE PROBLEM

Did you ever think about minerals being spread around the ocean floor? No probably not today. Now think about who OWNS those minerals. Many nations around the world claim that all the minerals should belong to them. The real problem is how we can get to them. Minerals near the ocean floor are not hard to get, and are not too expensive, however the minerals further into the sea are harder to mine which makes it more expensive. There are new technologies that we need to get deeper and deeper into the sea. Some rich countries can provide enough money and afford the new technologies. Nations that are still not as rich and are still developing do not agree with that. The Law of Sea also thinks that the minerals are everybody’s property and anyone can take them.

ANALYZE THE OPTIONS
Rich nations have a problem. They know that they can afford to get the minerals, but which inventor is so trustworthy to give money to, so he can build a machine that would work? There are of course some nice and fair nations who have the problem of thinking who to share those minerals with. However the nations that are still developing have a bigger problem to think about. How and where do they get the money to mine the minerals? If I was part of The Sea Law I would try and give the countries that are left out or not close to the sea such as the landlocked nations some money to get them started. I would also make an agreement with them. The more minerals they mine the more money they will get to expand and continue their work.

Conclusion-
In conclusion, my opinion is this; The nations that are developing need some money support in order to continue developing, some countries have barely enough money to support their country with so how can they spent the money that their people need to mining minerals? I also think that the rich countries should have a limited about of Sea for mining, and the rest should be open to anyone who wants to mine, but of course they need the money to do it.

Thank you for taking your time and reading all these information that I spent so much time on collecting and I also hope that you have got some background knowledgeable on The Oceans Minerals! Thank you and be sure to read the next blog post!

Please feel free to live any comments or suggestions beneath this blog post! Thank you and again I hope that you have learned something new about Who Owns the Worlds Minerals! See you soon!
