Know and Want know- Forces and Motion

Know

Force/Motion

What I know about force is it is something that is putting against something else. For an example in the video that we watched, the balloon that hit the time warp guys face it put so much force on it that it burst. Force can also be put in a different way. For an example, if you have a plate with 4 strings attached to it on for sides, and stick all of those together so you can hold all of them. So, if you spin it around you, you can see that it is puling towards you. You can identify that by putting a glass of water in the middle of the plate. Now, when you spin it, the water doesn’t spill because the plate, not the glass, is getting pulled towards you and therefore it doesn’t spill.

What I want to know

· How much force does it take to brake a baseball?

· How/Why do we use Newton’s 3rd law in forces and motion?

· Why do we use Newton’s law in forces and motion?

· Why does a basketball burst when it is put under a lot of pressure?

· Why does a bullet slow down when it goes through a lot of cans of soda?

· Why doesn’t it just burst rite through all of them?

· When do forces come in handy?

· When does motion come in handy?

Group Discussion :P :) :D - Reflection!

GROUP DISCUSSION:

Why are minerals important?

Answer: Some minerals can contain proteins, used in daily life; for example, buildings, spice up food, kitchen items, glass, jewelry, clothes, tablets, etc.

What minerals are found in the world’s oceans?

Answer; Oil, salt, potassium, Magnesium, sand and gravel, limestone and gypsum, phosphorites, placer gold, tin, titanium, water.

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

Answer: The landlocked countries should get a share, poor countries/developing also should get some from wealthy. Wealthy coastal nations should get most profits, but also share with poor/ landlocked/developing. Everyone should have the right to own a little bit of the profits because the ocean doesn’t belong to anyone.

What are the problems with mining in the ocean?

Answer: It’s very expensive to get to the bottom and extract the mineral deposits. Landlocked countries can’t get to the ocean and only the wealthy coastal countries have enough money to get to the bottom. Mining can ruin the environment sometimes. The reclamation act should be valid for ocean mining too. Spilling (toxic, oil) from boats is also a problem.

Who owns the oceans minerals?

Answer: It’s everybody’s property and it goes to anyone who gets there and takes it out first. On the coast of a country then that country has the right to get it but should share with landlocked countries.

What are the rights?

Answer: Law sea treaty states that ocean mineral deposits are property of all people and must share with all nations. Some people think that because of the treaty the wealthy coastal Nations should share their technology and profits.

Do you agree with that?

Answer: We agree with that as long as the wealthy coastal nations should share all profits/technology/money with landlocked/developing nations. We think that 200 miles (EEZ’s) are good as long as they share. Trading but the developing countries get more.

Proposal: We propose that wealthy coastal nations should share/trade profits with landlocked/developing countries because the profits are everyone’s and some people don’t have the money to get the minerals. WE agree that all minerals are everyone’s property and that anyone who gets some of the profits should share or trade at least a little bit.

Reflection:

I think that me and my group worked very well together and we cooperated with each other. We were very organized with the information. We used the internet but mostly not, we mostly used our thoughts of what we learned in class. The speaker(Me) did very well talking to the class and explaining all of the questions. But he didn't just read it, he took the most important information from the things that we wrote in the thins up above, and also underlined the important information. So all in all i think that my group worked very well and cooperated with each other.

Mining in Maine!!!!! :) :D

• Calcite is mined using quarrying or underground mines.

• If the calcite is not too deep in the ground then they use quarrying to mine it!

• Calcite is used for making glass, paper, buildings, and many other things.

• One of the the Mining company's is called Marston.

• Calcite has more uses than almost any other mineral. Most is used as a construction material in the form of cement or concrete. In agriculture it is used as a soil treatment to neutralize the ground and it fillers it.

• In a powdered form, calcite often has an extremely white color. This quality makes it often used as a whiting. Calcite has long been used as a whitewash and it is also used as an ingredient of paint.

• The acid neutralizing ability of calcite is used in medicine

Calcite- In Maine- Notes

Website: http://library.thinkquest.org/05aug/00461/calcite.htm

	What is it and where was it formed? Calcite is mostly found insedimentary rock. Calcite turns into the rock called limestone. Some limestone is made when sea creatures die and their skeletons and shells fall to the bottom of the ocean. They pile on top of each other, push on the lower layers, and the pressure makes limestone. All limestone starts in water. There are places in the middle of the United States where there used to be a sea. The water has been gone for millions of years. Even though it’s dry now, limestone can be found there. If you add pressure and high heat to limestone, it changes into marble, a metamorphic rock.
	How and where is it mined? Calcite is mined using quarrying orunderground mining. If the calcite is not far underground, then quarrying is used. If it is too far underground for quarrying to work, then underground mining is used. It is found in New Jersey [Franklin], Tennessee, Illinois, and other states of the U.S.; Mexico, Germany, India, England, and other parts of the world.
	What is it used for? Calcite/limestone is used for making glass, paper, photography, statues, building, and animal food. The Ancient Egyptian Sphinx [below] is made of limestone. http://answers.ask.com/Fashion_and_Beauty/Jewelry/how_is_calcite_mined Calcite is mined using quarrying or underground mining.

Notes on WHO OWNS THE OCEAN!

Who owns the mineral deposits there?

(The 2 pages that you sent us as an atacment)

Rich mineral deposits lie on and just beneath the ocean floor. Coastal nations have the right to mine deposits near their shores. Today, they are mining minerals from the continental shelf. But mineral deposits on the ocean floor beyond are open for all nations.

Find out what EEZ's are in the 3rd section of the

article.

http://geography.howstuffworks.com/oceans-and-seas/international-water2.htm

EEZs are extensions of a state's rights to resources offshore. The boundaries of an EEZ go well beyond territorial waters, extending 200 miles (322 km) from shore. EEZs presented a discrepancy, however. This new EEZ restriction of 200 miles (322 km) narrowed other nations' boundaries. The U.N. compromised by allowing nations with wide continental shelves to extend their EEZ up to 350 miles (563 km) from shore, provided nations could prove the width of the shelf offshore.

What is an International Waterway?

http://www.google.com/search?rlz=1C1RNPM_enUS388&sourceid=chrome&ie=UTF-8&q=What+is+an+International+Waterway%3F#hl=en&rlz=1C1RNPM_enUS388&q=International+waterway&tbs=dfn:1&tbo=u&sa=X&ei=FV2hTY2NEMXMtAbtzsDnAQ&ved=0CBQQkQ4&bav=on.2,or.r_gc.r_pw.&fp=384aef4afa8e1652

The terms international waters or trans-boundary waters apply where any of the following types of bodies of water (or their drainage basins) transcend international boundaries: oceans, large marine ecosystems, enclosed or semi-enclosed regional seas and estuaries, rivers, lakes, groundwater.

Who owns the ocean?

Who owns the ocean?

1. America, Canada, Russia and Norway are all fighting against each other to get to the Arctic to get to all of the minerals that are under the ice. The government said "The area around that country is owned by that country, if it is not next to any country, then that part belongs to who ever gets there first and clams it first." I think that that is a very fair law for the government to put up.

2. Only wealthy industrial nations will be able to afford the cost of mining on land and off of land. These industrial countries think that if they spend the money on mining, that they should get all of the profit. But nations that are landlocked and developing nations that lack money and technology, disagree with their opinion. They think that they should have a fair share of the profit because they are in need of more natural resources than others and landlocked nations can’t get to the sea to get the resources that they need so they need to buy them from someone else. The reason that they are saying that they disagree with the wealthy countries is because the land locked countries are running out of resources. "By 2003, 157 nations signed the Law of the Sea treaty. This treaty said that ocean mineral deposits are the common property of all people. It also said that mining profits must be shared among all nations." By that time the nations that were landlocked and the nations that had a lack of money and technology were very happy that they were going to start getting there fair share of resources again. I think that I could probably reassure the developing nations that they will not be left out by giving them enough resources until they are wealthy enough to take care of themselves and get the resources on their own. They will also have enough money to start mining on land and off land.

3. Pacific ocean: I think that Japan, New Zealand, Australia, Canada, and South America should all share the profit from the Pacific ocean. The pacific ocean is a very vast body of water that contains many minerals, oil, and natural resources that we use in our everyday life.

Atlantic ocean: I think that south Africa, some of north Africa, south America, and some of north America should all share the profit from the Pacific ocean. The reason i didn't put Russia, Norway and Canada in there is because they are all fighting for the Arctic ocean witch i will talk to you down below.

Arctic ocean: America, Canada, Russia and Norway are all fighting against each other to get to the Arctic to get to all of the minerals that are under the ice. Under the ice there is supposed be a large amount of oil and other natural recourses that we also use in everyday life. That is why all of the country's are fighting for the oceans were the most minerals, crystals, oil and natural recourses are. Thees are the most valuable oceans: The Atlantic, Arctic and the Pacific oceans.
