Forces and Motion

In science we are starting a new unit on Forces and motion. What I know about that is that motion is the movement of things and that gravity is the way things stay on the ground. Also that there is a Nutions law which is inertia.

What I would like to learn is some more forces and more about the Nutions law.

I would like to learn this is by doing projects and making the pendulum.

Reflection


I think that in this unit I did very well. This unit started and finished just the way I wanted it and there is no way that I could improve it. I worked hard and learned a lot. And all the activities that we did were great, like the crystal garden and the where we could choose a volcano and then make a movie or anything else to show the info on that volcano. All of the activities where very fun and entertaining.

During this unit I learned a lot. I learned that you can make your own crystals. I learned that there are types of rocks. Also the layers in the earth. This list could go on, but my bubble us map will show you all the cool and interesting things I learned. 
 There are many things that I found interesting in this unit. I found interesting that you can make crystals yourself, and that there are types of rocks as I said above. Another interesting thing is that there are 2 ways of mining.
For me this unit was great and had many good parts, and no bad parts. So the whole unit was great. And there is only 1 thing that I would change for the next grade sixes; it is that to make the crystal garden with the crystals to grow.

Who owns the Oceans minerals reflection

During this discussion I have learned a lot. But some of the stuff I did know. It was fun looking at everyone’s opinion of what they think is right. I learned that not only the people close to the shore should get the oceans minerals, but also the poor and rich. I also learned that some minerals that are found in the ocean are so valuable that we depend on the water if we want to have it, like salt.


During the discussion and group and I fought for a little because some people did not want to work, but then we figured everything out. Over all this was fun and I learned a lot.

Who owns the Ocens minerals.

Minerals are important because they have many uses and they are valuable



The oceans minerals are Halite, Potassium, Magnesium, Sand, Gravel, Limestone and Gypsum.


These minerals are valuable because they have many uses, for example halite is used in food and we find it only in oceans


According to the sea law the nations that own the part of the ocean should mine in that specific area, the nobodies land should be share by all the nations that wish to mine and maybe the inland nations too.


The problem with mining in the oceans is that the water around gets polluted and the pollution kills the fish which ruins the food chain.


Everyone owns the oceans minerals and there should be no differences in poor and rich countries because everyone has the same rights.


The rights say that all the nations should get the same amount of the oceans minerals and there are no differences between developing and rich countries.


Yes we agree with the rights because it is not fair for the developing counties that they are left out. Rich countries such as the USA want the part of the Arctic minerals when they are not even touching the Arctic Circle.


All of the countries should share, the mineral profits should be shared over the world evenly and rich counties should compromise about how much they keep for themselves and how much they give away.

My country mineral


Hello, today I am going to talk about a mineral that is found in my country. Well, its aluminum. Aluminum Rio Tinto company, and after it is extracted from the ground it is sent to factories to be renewed and to look nicer.

Aluminum is used in all kinds of items that we all use every day. Just a few are:

Motors for cars
Frames on bikes
Brake handles
Tools
cats
dogs
Conductors for electricity
Solid fuel stabilizer
Anti-perspiring in deodorant

Aluminum is valuable simply because it has many uses. And my country does not depend on this mineral because it is found in many other countries.

Pacific and Atlantic

1) The right to exploit minerals beneath the ocean floor is highly consequential these days, as it is thought that large deposits of undiscovered petroleum are buried there. The rights to the minerals beneath most of the ocean floor have been allocated to various governments, although some territory remains either unclaimed or in dispute. Any resolution depends on the bases of various claims to sovereignty and ownership with respect to seabed mineral resources.



2) Add bigger taxes to people who shop, ask for help from other nations, make every product cheaper and join country competitions and try your best to win are only some of the possibilities to make a nation more wealthy.


3) I think that North and South America, Asia and Australia should share the mineral profits of the Pacific Ocean because the Pacific is bounded by Asia and Australia on the west and North and South America on the east. The North and South America, Africa and Europe should share the mineral profits of the Atlantic Ocean since they are the closest to the large ocean.


4) Generally, a state's EEZ extends to a distance of 200 nautical miles (370 km) out from its coastal baseline. The exception to this rule occurs when EEZs would overlap; that is, state coastal baselines are less than 400 nautical miles (740 km) apart. When an overlap occurs, it is up to the states to delineate the actual marine time boundaries. Generally, any point within an overlapping area defaults to the nearest state. A state's exclusive economic zone starts at the seaward edge of its territorial sea and extends outward to a distance of 200 nautical miles (370,4 km) from the baseline. Thus, the EEZ includes the contiguous zone. States also have rights to the seabed of what is called the continental shelf up to 350 nautical miles (648 km) from the coastal baseline, beyond the EEZ, but such areas are not part of their EEZ. The legal definition of the continental shelf does not directly correspond to the geological meaning of the term, as it also includes the continental rise and slope, and the entire seabed within the EEZ.


5) Body of surface water, such as a bay, gulf, or river, that forms a boundary between two or more states, drains or flows through two or more states, and/or is recognized as necessary channel of one or more states' access to the open sea.


6) The Pacific and Atlantic Oceans do not specifically belong to anyone because that is just one of the water bodies. It is as if we said that the Danube belongs to Serbia but t actually does not.

7) Deep ocean mining for manganese nodules is under development by several multinational mining consortia. Initial estimates of probable environmental effects of this mining were made before any actual operations were conducted. Recent pilot mining tests near Hawaii have provided an opportunity to verify and modify the initial estimates. The two principal initial impacts of mining are in the near surface water associated with increased turbidity caused by mining discharge, and in a relatively limited zone at the sea floor associated with collector traverse. Examples are presented of estimates of reduction in primary production in the turbid plume as well as the contrasting effect of increased nutrients. Effects of the mining collector on benthic populations are considered. The limitations of extrapolation of results obtained during pilot mining tests are discussed.
