Well first I know a little but really not that much and by looking at videos and listening to information, I would like to learn about it.
Some things that I do know is like in the video when I saw Toni Hawk and he was skate boarding on a loop type thing. And he had to go up in the air. For him to do a loop he would have to go very fast. Also the same with a roller coaster it would need to go very fast going down and go in loops or else the people would just fall out of the roller coaster. The same thing with the people ridding bikes upside down they would need to go very fast to be able to go on walls and the ceiling.
One thing that I also learned is when gravity in pulling you down very fast things will go up. Like if an elevator was just falling very fast and you were in it. You would go smack! onto the ceiling. So sometimes if you are in an elevator and going down you sometimes feel like your body is going up. And that is the force of motion. So that is why elevators are slow. At amusement parks they usually have the ride where you sit on a seat your feet dangle you go up and then it just drops. Well if you didn't have a seat belt you would be in big trouble. Because you would fly up then fall back down to earth. So the seat belt holds you back down. And again same with the roller coaster you have to have seat belts because when you are going down you can like fly up. Sometimes I hold onto the seat belt because I feel as if I am going to fly out.
So I would really like to learn about force and motion I really think it will be a fun and interesting thing to learn about.
Some of the things that I would like to learn is the definition of force and motion? I would also like to know who discovered force and motion? What forces will affect the earth? Can you over come the forces of gravity? And I would also like to learn about it by watching a Bill Nye. Difference between forces and motion? What does gravity depend on?Do forces and motion matter in life? Why do things react to force and motion? Do forces and motion have something in common?
These are some of the questions I would like to know.Then I did some research
The definition of force is the capacity to do work or cause physical change; energy, strength, or active power. The definition of motion is the ability or power to move.

Earth's Inner secrets
Well first all I can say is that I have really learned a lot about earth these past months. So here I would like to share some information that I have learned about earth.
First I will tell you about the rock cycle. In the rock cycle there are 3 different types of rocks that the rock will turn into. Sedimentary turns into Metamorphic, and then Metamorphic turns into Igneous. Sedimentary is formed by bits of pieces of rock being being taken by water or wind and then it settles down at the bottom of rivers, lakes, and the ocean. Then it starts to form together and make rock. Metamorphic rock is formed by all the pressure and heat forming it to be change a become metamorphic. And then Igneous is formed by magma going into pockets inside the ground and it is also formed when I volcano erupts. Some of the rocks that are Sedimentary are Sandstone and Limestone. Some of the rocks that are Metamorphic are Marble and Shale. Some of the rocks that are I Igneous are Obisidian and Pumice.
Now I will tell you about volcanoes. How volcanoes are formed is when there is lots of pressure and heat and its just to much so a hill will form out of the ground. And then it will grow forming a volcano. Also inside a volcano there is magma. But when it comes out of the volcano the magma then is Lava. Then when it is in the air forming dust and things like that it is called Tephara. ALso where the tectonic plates meet is where volcanoes usually are. Because when the 2 plates go against each other it forms a voclano. There are many volcanoes around the Pacific ocean so it is called the Ring of fire.
The earth has five layers the crust, upper mantle, lower mantle, outer core, and the inner core. The Earths crust is the thinnest layer of the earth. The mantle is very thick but not as thick as the core. And it also has magma flowing threw it but not as hot as the core. The core is the hottest and it is also the thickest layer of the earth. The earths core is hotter than the surface of the sun.
Mining is a big problem because well first. We need to share our mineral profits but some countries do not want to. And second we need to keep on going deeper and deeper into the earth to get minerals and rocks. But because we are going deeper in it is harder and mines can collapse. One thing that you need to do when people mine is when they get the minerals or rocks they need to put where they dug of the rocks or minerals place back so are replanted grass is put there they fix it all up so they don't take away the animals homes.
Minerals help us in everyday things. If we didn't have minerals who knows where we will be today! There are many many minerals. The definition of a mineral is,A mineral is a naturally formed, inorganic solid that has a definite crystalline structure. And here is a question what are minerals and this is what they are.
Solid: cannot be a liquid or a gas.
Naturally Occurring: Found in nature, not man made.
Inorganic: Is not alive and never was, no living
Fixed composition: Has a chemical formula, most are formed from compounds of two or more elements, some minerals consist of on element ex.
Crystal Form: A definite structure in which atoms are arranged.
So this is some of the things that I know about our earth. As I said before I have really learned a lot about earth these past few months and I am looking forward to our next unit. So thank you Ms. M for teaching me about Earth.

Reflection on Oceans minerals discussion
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
Reflection
First I think we did a really good job on this discussion. We all listened to each others comments and also learned new things. And while we were doing that we had fun at the same time doing it. Everyone stayed on task we always made sure we had enough time to answer every question and we did it all and had good answers. Everyone when they did there job did really well. Ajda did a great job writting it all down. Ogi did great because we stayed on time. And Matija did a really good job reporting our information and explaining what we talked about. I think we made a good team.

Australia's minerals
A little bit of history
On the 28th July 1994 Opal was declared to be the national gemstone of Australia. Australia supplies the world with 90 percent of Opal. In 1840 Opal had been discovered. In Australia German geologist, Professor Johannes Menge discovered a common greenish opal near Angaston (South Australia) near the north of Adelaide. Then in 1868 boulder opal was mined from this deposit and then it was sent to England for evaluation during 1873. Soon enough the boulder opal was then known as Barcoo opal.
1. How does it form?
Opal is similar to quartz, amethyst, and glass. They form by silica and water. Opals are created when weathered silica seeps into a little crack as gel. The silica contains a lot of water in it. It then mixes with sodium silicate also known as Water glass. As the water evaporates the gel hardens. If the water evaporates to quickly then the opal will crack but if it evaporates slowly will be stable and also if it has a nice fire it will be considered a gemstone.
2. How is it mined?
7. Does your country depend on these minerals being mined?

If the water evaporates to quickly then the opal will crack but if it evaporates slowly will be stable and also if it has a nice fire it will be considered a gemstone.
2. How is it mined?
Here are 4 ways of how they mine opal. First the simplest way is shaft sinking with a pick and a shovel. A shaft is sunk straight down until it hits the opal dirt. And then a handpick or screwdriver is used to extract the opal found. The second one is open cut mining. This is done by
a heavy machinery to remove large amounts of the opal dirt. This way of mining is much more expensive. The third one is noodling. Many locals search though mull rock for pieces of opal. They use a rake and sieve for tools. Some have a machine noodling by allowing big amounts of opal dirt to travel on a conveyer belt under ultra violet light, which can detect opal. The last one is Puddling and Rumbling. A puddler is a large mesh lined drum attached to a motor. It rotates and turns the clay into sludge water and then it is pumped into the drum. Then it escapes through the mesh.
3. Who is the mining company?
This mining company is GM which means great mining.
4. Where do the materials go-are they exported to other countries to factories?
Australia produces around 95% of the worlds opal is used in jewelry. Other countries which only have a little bit of opal are Honduras, Mexico, former Czechoslovakia, and Brazil. Butall these opals look different when they are found. Australian opal is the finest in the world. They export it to many countries.
5. What are they used for?
Opal is not really used for that many things. Mostly opal is used for jewelry. It is used for jewelry because it is very beautiful and it has a very soft stone. It can be sometimes used for buttons, furniture inlay, and small sculptures.
6. Is it valuable?
It is important to know what type of opal you have because the colour usually depends on how valuable it is. The black opal is more valuable than the boulder opal it is also more valuable than the light opal. The darker the body colour, the more valuable the gem. Red fire opal is the most rare. Followed by green, orange, green/blue, and blue. But also the pattern and clarity of an opal also counts. So if a blue/green had a cool beautiful pattern it could cost more than the red.
7. Does your country depend on these minerals being mined?
The Australian export market for opals is at estimated at $60 million with 165 billion in total mineral exports, therefore Australia does not rely on these minerals as a source of money.
