In my science class we had to research volcano and a topic on that volcano. In my group of three we had the volcanoes "Mt. Aso and Mt. Kilauea" and the topic that had to be connected to the people was when do restrictions come up and a bit extra on the people, I was getting the information about the people. Once we had all of the data we had to make a presentation of our choice, we chose to make a movie. I think our presentation was considerably well considering that we are only in sixth grade and it was the first movie. I think our movie could have had a bit more information in it.And in the last scene the volume was a bit to soft so we had to say it.Something good we did was that it was not boring because we put a bit of a story into it. I think if I gave myself a grade out of six it would be a five. I would give myself that because there was a difficulty hearing the video but we did have good data. The whole time we were watching others presentation I learned quite a bit. I learned some people actually live around volcanoes, there are three volcanoes in the Philippines, a caldera is a big hole made by a big explosion by a volcano, Mt. Etna is in Italy,and many other facts. A lot of people are affected by living by volcanoes. The volcano may give them good soil so they could be planting crops there, they have to be careful if the volcano erupts, the SO2 level gets to high, and if the volcano starts releasing CO2.I also learned how volcanoes affect the world the in the following ways; smoke released destroys the ozone layer, the volcano helps soil, and they can simply be a great thing to look at.

Modeling Mantle Convection Currents
In my science class we did a lab to see what convection currents do. What we did was we put hot water in a cup and put it at the bottom of a big container of cold water. The hot water symbolized the mantle.
The guiding question is "How might convection in Earth's mantle affect tectonic plates", and my hypothesis was "I think that when we poke the holes it will shoot out the water because it is hot and it will make the plates come together. My hypothesis was correct. When I poked the holes the water came out slowly but the bits that came up when they cooled the currents went down and that happened with all of the currents. When that happened I could notice that the little pieces of paper I put on the top were moving very slowly together. My hypothesis was almost spot on, the only difference was that the water came out slowly it did not shoot out. When the water came out it was because warm water is less dense that cold water so it went up above the cold water and after that it cooled fast and went back down and I could see it because I put food coloring in it.
The pieces of paper in the large container acted as small tectonic plates. The little cup of hot water acts as the mantle. I think that this lab is a really good way of representing how the plates move. In some ways it is the same and those ways are that the water comes out just like magma and then cools the same way, and they both move the plates. The ways that they are different are that there are too many pieces of paper and there are not that many tectonic plates, the magma is much hotter, and the temperature of the water changes every where.

Mapping Earthquakes and Volcanoes
In my science class we started a little project to see where volcanoes and earthquakes normally are.
The guiding question was, "Is there a pattern in the location of earthquakes and volcanoes"? My hypothesis was
" I think that volcanoes form on transforming, diverging, and converging boundaries because the ground would be weak". I think my answer was in a way correct, but I noticed that the earthquakes and volcanoes were also close to each other. My other guess now is that when there is an earthquake it sets of a volcano. I noticed that all the volcanoes and earthquakes are either on or close by a plate boundary.
The volcanoes and the earthquakes are close together and they are on or close to plate boundaries. Now I think that they are by the plate boundaries because when the plates move it makes the ground a bit more weak so the magma can get out and form volcanoes.Earthquakes happen there when the plates move apart, come together, and slide past each other which causes earthquakes. I also think that the volcanoes and earthquakes are situated by each other because an earthquake might set off a volcano or the other way around. If I added more earthquakes to the map I think the pattern would stay the same because it makes sense that the volcanoes and earthquakes are by the plate boundaries. The movement of them can set each of them off.

Growing Crystal Garden
In my science class we are doing a fun project called "Growing Crystal Garden". It is a project that we make a garden The garden can be a Japanese or English garden and I chose a Japanese garden but a I made it a winter garden. After we make the garden we put crystal solutions on it and wait. This is going to be my observation table I hope you enjoy it.
At first when I saw my garden I thought it was the same but then I pulled out a microscope and it made it all different. I noticed that the crystals on the rock started to grow it looked really cool but it was small. The crystal solution on the tree the crystals on the pond have gotten a bit bigger. The crystals on the bridge have not changed.
DAY 1 January 26
So before I put the crystals on my garden it was just a diorama of a garden with one tree, bush, five rocks, and a pond so it was a bit boring. The next two days we put crystal solutions all over the garden. The salt solution I put on my pond and the next day when I looked at my pond it had already started to grow crystals they were in small circles that were sparkling if you look very close. They were spread out all over the pond and it looked really cool. And mostly the other just had a different color solution on it but they did not look different.
DAY 2 January 28
Now the crystals on my garden are really starting to grow. The crystals on the bush are growing great, they are growing a like little basketballs. The green crystals on my bridge are growing a bit slow but but steady. The crystals on my tree hardened the cotton on it. Because I added a bit more solution on the pond on day one I have a lot of crystals on my pond which makes it look really frozen.
Day 3 January 31
At first when I saw my garden I thought it was the same but then I pulled out a microscope and it made it all different. I noticed that the crystals on the rock started to grow it looked really cool but it was small. The crystal solution on the tree the crystals on the pond have gotten a bit bigger. The crystals on the bridge have not changed.
The last day of the two week period
Over this two week period I was observing my garden a lot happened, but now I do not see any differences in this last look. I think all of the crystals have grown as much as they can.
Now I have noticed where crystals grow the best, and the worst. I saw that on my garden that grew the easiest and the best was the salt solution. The crystal that grew the worst and hardest was the Borax. I also observed that the crystals grow better on denser and more leveled items like my pond. Crystals don't grow good on things like cotton as you can see at the photos at the bottom. I think the way you should put crystals on objects that might be covered or flat and more dense. I have noticed that on others garden the crystals also grow beneath objects. On mine I noticed that they grow on flat surfaces.
In conclusion, I observed that all in all the crystals on my garden grow best on flat and dense conditions, so I think that if a solution is on a flat but dense surface it will grow best. I have seen that on mine because they grew so well on the pond but not on the ball of cotton, and I noticed the same on many others garden. I have learned that crystals also grow when all of the solution is gone, but they don't grow that much they just grow a little bit. Now my hypothesis has changed to '' Crystals need the right conditions to grow like on a flat surface, and also there should not be puddles of it because it does not grow that well, I saw that on some others garden".
I had a few mistakes like, not getting enough solution on the rock, putting solution on cotton, and putting to little solution on my pond, but my crystals on the on the bush did quiet good.Now what I would have changed was made the experiment on something with low sides because I did mine in a shoe box and that was hard to work with. Also I would have dunked the rock into the solution, put more solution on the pond, and not put any on the cotton because it just turned it blue and there were no crystals. After this experiment I still have a few questions about crystals and they are" Does the temperature affect their growth, which crystal solution is of everyone, what solution is easist to make, and how many are their?"
Here is my garden and map
What is written on my map is the crystal solutions I used.

The Dynamic Earth
In my science class we went on this website that you might find interesting
http://www.mnh.si.edu/earth/main_frames.html
And from that we had to mainly read and take notes on rocks and mining, and the inner Earth.
The Inner Earth
Some things I learned from this website are that there are three main types of layers in Earth and in order from outside to inside they are crust, mantle, and the core. The crust is what we walk on and it changes in looks all around, the mantle is split up into the upper mantle and the mantle and it is just because a few of small details. The mantle is rocky, it moves the plates, it is solid hot and soft, and the lower mantle is really dense. The core is split up into the outer core and the core the main difference is that the core is solid. The outer core is molten hotand the core is even hotter than the suns surface and it is molten iron.
Meteorites
Meteorits give us multiple clues about the inside of the Earth. Meteorites come from asteroids which were made at the same time of the sun. We learn things about the Earth by meteorites, rocks, diamonds, earthquake waves, and the magnetic field.
Diamonds
Diamonds are made by the hotness and high pressure of the inner Earth and because the rocks they are found in are compressed and turns it partially into a diamond. Magma pushes the diamonds up and it takes about 4-15 hours to get up to us. You find diamonds under cartons and the older parts of some contenints and that is because it is too hot for them in almost all of the upper mantle. Rocks
Rocks
Rocks have Earths history in them. The also give hints about the creatures that lived in the past and the nature at that time and water shapes, makes, and breaks rocks. All rocks are made deep into the Earth and they are made from minerals and by heat and pressure, the deeper the the rocks are made the hotter and denser it becomes. There are different colors of rocks and kinds because of the way they are made and the minerals in them.
Mining
Mining is when miners go down deep into the crust and they mine for things we need or want. The things the mine are rocks, minerals, gold, diamonds etc.
This project was quite interesting but at times it got boring. But all in all it was interesting. These are not the only facts I got if you want more you should go to the link on the top of the page.

What we have learned this week and things I want to learn
In this past week of school in science class we have learned a lot of new information. You might ask your self how can you learn so much in just a week, well that's simple we watched two Bill Nye the science guy and took notes in class on earths structure. For earths structures we learned how land, water, and air interact and that is by force(gravity), tides, natural disasters/resources, and physical features. I also learned about earths structure; round, 3 dimensional, different layers, has magma inside it, 75% water, and natural disasters. I also learned more about the layers of the world like; core is solid iron and it is about 1500 degrees C, outer core is made of iron and other metals, the mantle is gooey and over 1200 degrees C, the crust is made of many things and its temperature varies. I also learned; sometimes volcanoes blow up and other times they just ozze lava, when volcanoes go off it can help nature, geysers blows out boiling water. the core is solid. Other things I learned were; caves can be under water under ice , and under rock, limestone is calcium, when water gets into a cave it dissolves the limestone that it is filled with and when it dissolves it all, it becomes a cave. More things that I have learned are; caves do not change quickly, when water drips off stalactite and it gets on the stalagmite the water will dizzolve and the minerals will stay to make them but it takes a really long time to make them, lava and ice can make caves. And know I hope that you can see that I have learned a lot this week.
There are many things I would like to learn in science, but I cannot learn them all this year. The thing I want to learn about the most are the kinds of minerals and what exactly they are. I want to learn about minerals because that has always confused me a bit so I want to learn about it so I can understand it. The things I want to learn about for them are; how many minerals bare there and not just the general ones I want to get deep into them, and I also want to learn the names of all of them and what they do and are. Another thing I want to learn about minerals is how do minerals effect people, animals, and plants.

Lab Reports
In my science class we did two labs and they are called "Cooling Race Lab" and "A Change for the Wetter Lab". I think how I did on the both of them is quite good. However I like how I did on the Cooling Race Lab more than I did on the Change for the Wetter Lab. I still know that I can improve greatly. On the Cooling Race Lab I can try to do the tests more carefully and get correct data because I did not get the best data. Another thing I could have done better was to use better wording and words. I think that on my Change for the Wetter Lab I should have also had better words and wording. Another thing I could have done to improve my lab was to make better conclusions by reading the data two or three times then think about it after that I should write it then reread what I wrote. I did enjoy making part of my Cooling Race Lab because you can think of many different things you can do in it other than following the instructions given. One of the things I liked about how I did the Cooling Race Lab was that I did realize that I might not have gotten all the data correct and that I mentioned that I made the mistake on my lab. One thing I liked about what I did on the Change for the Wetter Lab was that I did not give to much or little information in my answers.
