Today is the 23.02.2011 and I guess I haven't seen my garden since 2 weeks.... If your not sure what I am talking about, you can check my older posts and you will understand, but if you don't bother looking down, then here is an explanation: Last month or so, we were meant to make out own crystal garden, bring in objects and put solutions on which were meant to create crystals. As I look at my garden now, I don't really notice any change so I think I must have done something wrong. If I look at Sofia's garden, I see it doesn't have too much detail, but she has crystals... But an other fact, is that she did some crystals at home so that is a bit different from what I did. But on the other hand, on the other crystal gardens my friends where also disappointed because no crystals really grew on their garden either... My garden has only a few of crystals on some bushes, I would take a picture, but there is nothing new, if you are dying to see a picture of my garden, you are forced to scroll down and look at my older posts. I think from my perspective, crystals don't really grow that well on cotton or on a box. Next time, if we ever do this type of project, I will try to research a bit more on what type of objects crystals best grow on. If I could change anything in my garden, I would change the box it grows on and the land it stand on as well. Maybe next time I could also grow crystals at home and then bring them to school.After all, I didn't succeed as much as I was expecting on my garden. Next time I will take more care and try researching more:))

The Theory of Plate Tectonics
Over the last week or so, my class and I have been studying about the Earth and all about Plate Tectonics. I have already posted a post like this just about something else. Also here, we got a little packet to read and answer questions to. Here are my answers:
What is the theory of plate tectonics?
The theory of plate tectonics explains the formation,movement, and subduction of Earth's plates. There is more than one theory for how the plates have started out.
What are the 3 types of plate boundaries?
There are the divergent boundaries which are where two plates move apart. they usually make holes in the Earth.The second one is the Convergent boundary which is where two plates come together.These ones form small or big mountains, hills. Last, there are the Transform boundaries which are where two plates slip past each other, in different directions which mostly form and Earthquake.
What is a scientific theory?
A scientific theory is a well-stated concept or idea that explains very good and a lot of explanations.
We had a map on one page and the question next to it was: What direction is the Nazca plate moving?
If I look at the information given from the map, I see that this plate is moving kind of North East, even though not all part are going the same direction.
What will happen if a rift valley continues to pull apart?
First of all, a rift valley is a deep valley, and if it will pull apart, there is a chance that it will get destroyed and fall into the Earth.
What features form when two plates come together?
Mountains,valleys,spiky crust.
What questions would you need to answer in order to predict where the continents will be in 50 million years?
Some questions could be: How far away will the plates move? Is there any change from the moving plates over the years? Where will plates meet? Will winds cause problems? Will humans be alive? Will some disaster happen and change all the movement? Is there any information from the past that can help us find out?
I am not saying that we will find answers to all, but these are some of the questions, that popped up by the question.
What are plates?
Plates are rocky surfaces that are there for us and that have their own behaviors. They move, and cause our lives to change in good and bad ways. They always move, and they are made of deposits from the mantle.
These were some questions and some answers I cam up with, hank you for reading!

Modeling Mantle Convection Currents
On the first of February, 6b had to do a lab. One of the reasons was because we had a test coming up and also because it included what we were kind of studying about. The materials we were meant to use were: large plastic bottle, food coloring, small glass jar, aluminum foil, small pieces of paper, cold and hot water. We were focusing on observing for this lab. What we did was fill the plastic bottle with cold water, and the small glass jar with warm. Place the aluminum over the small jar and make sure it didn't go off. Finally, place the jar into the bottle and place some pieces of paper on the water, then we were meant to poke holes into the aluminum, and see what happened to the waters meeting and to the pieces of paper.
Hypothesis:
Before we even started the lab, my hypothesis was that when we punch the holes into the warm water, it will come shooting up and make bubbles, but I was wrong.(I was thinking of a volcano most probably)
Observing:
When my partner and I punched the whole into the colored, hot water, the color slowly started to get out of the jar and as it reached the top were the paper were, it started making some join and others disperse. The water was also moving anti-clock-wise and was not still. As I said before, my hypothesis was not right because nothing shoot up really fast, well except when I poked the holes in 2 or 3 bubbles popped up but no explosion or anything happened.
Conclusion:
As I mentioned in my observation, my prediction was wrong because nothing came splashing out of the bottle except for the small bubbles that came running up when I poked the holes in. Also, in conclusion I saw that the warm water was actually pretty slow at rising, but it did rise, it was very similar to wind, the hot goes to the top and the cold to the bottom.
