I'll give you the assignment pass tomorrow unless there is no blog due like schoolloop says.
Contradicting what the board and you said, that is why I am still posting this as to not have a zero.

Wac- Nuclear Energy Expansion
Expansion into Nuclear Energy
Nuclear energy is a form of energy that is made in a Nuclear Power plant. The power plants work by making mini Nuclear explosions of uranium. This releases a lot of energy that heats up water so it turns into steam. The steam goes up into the turbines, creating electricity. Then the steam escapes like you might see right now. This process is very wasteful and dangerous. That is why scientists found a new, safer, less wasteful, different way. Now nuclear energy could be a very efficient and clean energy source that we should use a lot more of.
Before we get into all this stuff about Nuclear energy and why it should be used, let me give you some background history. Atomic radiation was first discovered in 1895 and they knew that they could do something with this new discovery. But Nuclear fission was only discovered in 1938 by Otto Hahn and his assistant Fritz Strassmann. It was then developed fully by 1945. Most of the last 6 years or so were spend more on bombs though. Then the first nuclear power plant was completed in 1954 by USSR. But the first commercial electricity-generating plant that used nuclear energy was in Shippingport, Pennsylvania. It reached its full design power in 1957. Since then Nuclear has continued to get more and more advanced. Only recently did we realize how much damage we were doing with this technologie (like many other things). So scientist went hard at work to find a new way to create nuclear energy.
This new process works with fusion instead of fission unlike the old process. The new nuclear power works the same way as the sun. Atoms fuse with each other creating large amounts of energy. This still comes with some by products like helium. But these don’t have as bad effects as what is left in fission. This method produces a lot more energy with a lot less waste.
Modern nuclear energy is the most efficient way of making energy. But the old reactors are “like opening a water bottle, taking a sip, and throwing it out.” said in the video The fight to rethink (and reinvent) nuclear power. But a women named Leslie Dewan found a way to fix it, explained in the previous paragraph. But these power plants will not begin construction until 2030-2050. But in the article, What’s next for nuclear? Gabriela Quirós said, “A recent EPA study shows that in order for the country to reduce its carbon emissions enough to slow down climate change, it will need to boost its nuclear energy production.” And who knows if it will be too late by 2030-2050?
Some might say that nuclear power is very unstable and dangerous but in the same article they mentioned, “Proponents of nuclear energy say that the risks of an accident should be weighed against the health effects from burning fossil fuels. The American Lung Association estimates 13,000 people die in the United States each year from breathing soot particles from coal-fired power plants.” If you add that up, that is a lot more people than have ever died from Nuclear power. Also, these new power plants that they would build are made virtually impossible to have a meltdown.
In conclusion, nuclear energy is clean, safe, and efficient. And people just found a way to make it even cleaner, safer, and more efficient. It is way safer than oil and coal burning. It is also cleaner by a long shot. Nuclear energy may have a bad name right now, but it is quickly earning back a great name. Nuclear energy is the energy of the future.

Weekly Blog(4/20/2018)Nuclear power plants
Modern Nuclear power plants are powered by fission. Fission (shown below) is the process of taking an unstable uranium and shooting a neutron at it. Then the uranium atom splits releasing energy and more neutrons, etc. But this is very wasteful. They can only explode about 2% of the uranium fuel, leaving 98% to be buried underground for thousands of years. But there is another, new way, (shown on the left) that is the opposite reaction. This is called fusion. That is is how the sun works.
S&EP
I used evidence to defend my explanation. I answered the question "is Nuclear power the future?" providing the facts that it is a lot more space and cost efficient that every as evidence. Making these also provide jobs that boost the economy. When you here nuclear power plant, there is an almost certain chance you are thinking of the picture on the left. Did you know that 13,000 people die every year from fossil fuel burning and air pollution? That, added up is more people than have ever died from anything nuclear. From chernobyl to hiroshima.
XCC
I could use this technology to "take over the world" by spreading awareness of how amazing fusion is. Then people can sponsor the building of plants. Then a lot of places would build these power plants. This could stop or at least slow down global warming by a lot. That is how I would take over the world using that technology.

Weekly Blog(4/13/18)Climate Change
Summary
Climate change is the increase and decrease in average temperature. There is a climate change happening right now. But the thing is that this is not a natural climate change like the other ones. This climate change is caused by humans and their carbon/methane emissions you've heard so much about. Carbon emissions are caused by oil refineries, gasoline burning, and factories. Methane (which is 7-10 times more potent) is caused by food waste.
S&EP
To demonstrate/model this process we used a lot of online simulators and models here: https://has.portal.concord.org/. This brought me closer to master on this subject because it helped me understand what helps the environment and what harms it. I found out that we have to bring our carbon emissions down by 50% of 2010 emissions. Our temperature is rising rapidly. I personally doubt that we can lower our emissions that much.
XCC
The act of adding more carbon into the atmosphere, then getting hotter is cause and effect. This is because one thing happens, that another thing happens because of that. There are such things as positive feed back loops where one thing causes another, that causes the original thing again. An example of this is CO2 making it hotter. The more water evaporates, holding more heat in the atmosphere, etc. There is also another process that is happening. It gets hotter, more water evaporates, making clouds, making it cool off. These are just some examples of cause and effect in our climate.

Project Blog(3/30/18)Popocatepetl and Iztaccihuatl
Summary
In the myth, iztaccihuatl and popocatepetl are gods and lovers. Popocatepetl is an aztec warrior. Iztaccihuatl is a princess. One day she hears that he has been slain in battle and was so sad that she killed herself. When popocatepetl found out, he was very angry and turned into a volcano. She is now a mountain.
Backward-looking
Before this project, I had no idea that these existed. Much less how to say them. THe process we went through to get this was that we originally madea 3d model of popocatepetl out of clay. But that was way too small and it looked nothing like that volcano in specific. So then we had to draw it out on a piece of poster paper. Then we colored it with water color and it is very pretty(in my opinion).
Inward-looking
I really like how this project turned out and think that it is very pretty. I like how the colors make it look majestic. But I don't like that we couldn't have a 3d model like we would have had if we had more time. I found it frustrating when I told my group to make a cardboard frame so the volcano could be bigger. But they just made a tiny lump of clay in the shape of clay in the shape of a generic volcano. The reason I did not just do it was because they said they would because I was going to their house later for final touches because I could not make it early like everyone else.
Outward-Looking
We did our work differently because we we drew it instead of making a 3d model, I won't explain again. One thing I would like people to notice is the water color we used on it and how it gave the mountain a majestic feel. I would give this project a B+ because it is not a 3d model like it was supposed to be. When my classmates look at it, they notice that it is a drawing. When someone looks at it I want them to nice that we will not give up because our 3d model didn't work so we had to try something else.
Forward-looking
If I would do this again, I would be there for the beginning stages. I would make a cardboard frame. Then cover it in paper mache. Then I would install a pvc pipe in the middle. Finally I would paint it like the beautiful popocatepetl volcano. Then I could explode it with baking soda. vinegar, and red food dye.

Popocatepetl and Iztaccihuatl and a pair of mountains in mexico. Iztaccihuatl is an active volcano and Iztaccihuatl is a flat mountain. The ancient myth behind these two is that Popocatepetl and Iztaccihuatl were gods and lovers. Then one day Princess Iztaccihuatl heard that Popocatepetl had died. So she killed herself. Then Popocatepetl found her dead body and was very enraged and blew up like the volcano he is today. To read more about this you can read this article: https://www.inside-mexico.com/the-legend-of-popocatepetl-iztaccihuatl/
S&EP
I used models to demonstrate the explosion of Popocatepetl to. My group is building a volcano model popocatepetl. This helps me closer to mastery because now I understand more about building models.
XCC
In the myth, when someone dies you get angry. This is cause and effect. Also, when subduction occurs, it creates volcanoes. Another thing is that in ancient culture, if people don't understand something (like volcanoes) they make a myth explaining the story behind it. This can help people be less afraid because people are afraid of what they don't understand.

weekly blog(3/9/18)Plate tectonics.
http://www.physicalgeography.net/fundamentals/10i.html |
Summary
Tectonic plates are the plates that cover the earth. The plates may feel stable, but they're in constant movement. These plates expand and contract on each other. First, when an continental plate meets an oceanic plate, the heavier oceanic plate sinks under the light continental plate and melts back into the mantle. This is subduction. Subduction creates pressure in the magma and that pressure is released in near by volcanoes. There are also many other things that can happen. When two continental crust collide it creates mountains. When two oceanic plates pull apart, it makes stuff like the Mid-Atlantic ridge.
S&EP
To demonstrate the plate tectonics we learned, we used; frosting, fruit roll ups, and gram crackers. The frosting was representing the mantle, the fruit roll ups where the thin, dense oceanic plates, and the graham crackers were the light continental crust. We demonstrated the making of ridges by putting the fruit roll ups on the "mantle" and spreading them apart. Then we showed subduction by putting the FRU (fruit roll up) next to the graham cracker and pushing them together so that the FRU was pushed under like subduction. Then we pushed two wet graham crackers together to make a mountain. And finally earthquakes. We simulated this by having two DRY graham crackers rub against each other.
XCC
It is cause and effect when convection currents under the crust in the mantle cause the crust plates to move. When they move all these other things happen that I told you about. Some of these (like volcanoes) cause life to grow. Now we are using geothermal energy and harming the mantle. That's a different story.
