Lit. Poems
(The two poems I chose are the character poem and the diamante poem. I just wrote the color poem for fun.)
"Words or No Words"
Words
Strong, powerful
Daring, soothing, sharing
Deep, risky, safe, empty
Boring, relieving, hoping
Hollow, quiet
Silence
"Colors of Liesel's Life"
Death is a black,
Where as, silence is clear;
Out of the basements,
All the hearts are filled with fear.
The Champagn is yellow,
And the bread is stale brown;
The Jews are starving with hunger
While the mayor eats more than the town.
The sky was light blue,
The clouds were puffy white;
Death came to take Liesel
She enjoyed her last night
"One Tough Tree"
Liesel Meminger
Strong, kind, and troubled
Who loves to cuddle with a book
Who needs to know that Max is alive
Who shares her words
Who fears the death of her loved ones
Who'd like to see Rudy kiss her
Who dreams of the world being a safe place for everyone
Who ends up leaving with the tallest and strongest tree in the jungle

A recent article on Causes of Global Climate Change says that our CO2 emission, greenhouse gases, has increases and that is what is causing the climate change. According to the article, several people believe that the climate change and increase in greenhouse gases is a natural cycle. Not everyone believes it is due to anthropogenic ways
(not sure if I used the term correctly). Still, scientists are syaing there is no harming in cleaning the planet. I agree with the article that the increase in green house gases is due to human ways. The Greenhouse effect has always been taking place but it has rapidly increased during the last 50 years.
We have definetly increased our greenhouse emissions in the past fifty years. For instance, factories started, people started using cars, their was more trash to burn, etc. Therefore, I believe that the Greenhouse effect is natural and needed, but we have increased it way too much, and that is not natural!

The Collapsing Can!
Today in class, some of us did the collapsing can lab. It was a whole lot of fun! For this expirament, we needed an empty amuminum soft-drink can, a 2- or 3-liter (2- or 3-quart) saucepan, and a pair of kitchen tongs. There was a sauce pan filled with cold water on the lab table. First, we put a little water into an empty soft-drink can. We heated the can with the water on the hot pan. When the water boiled, vapor seeped through the opening in the can. We let the water boil for a while. Then, one of us took the tongs and quickly put the can upside down in the water. All of a sudden the can was crushed. The crushing of the can made me emit a frightening shriek. After the lab, I was left to wonder, why did this happen? I looked through my notes and discussed with other people and came to this concusion. I knew this lab was all about air pressure, so that gave me a start to my conclusion. When we heated the can with boiling water and placed it upsidedown into the cold water, there was a drastic change in temperature. The water vapor left the can and into the cool water because there is more room and less energy. The outside air pressure was then strong enough to crush the can because there was nothing inside the can. This lab relates to the Charles and Boyles law which we learned in chemistry.
Boyles Law: -When the pressure of a gas increases at a constant temperature, the volume of the gas decreases. -When the preasure is decreased the volume increases.
Charles Law: -When the temperature of a gas increases at a constant pressure, it's volume increases. -When the temperature of gas decreases the volume decreases
(from my notebook-class notes)
When the can was suddenly put into cold water it volume decreased because of the pressure around it.
This Collapsing Can lab was a lot of fun and I would mind doing it over, and over, and over, and over, and over AGAIN!!!

Vicious Volcanoes
Volcanoes are mountains which have an opening, or rupture, which allows magma and other gases to escape out from within the earth. Volcanoes form when the plates that make up the earth's crust move. The friction between the plates create enough energy to melt the rock anc form a volcano. A volcano eruption occurs when magma, from the earth's mantle pushes its way out of the opening in the earths crust. When the magma is thin, it creates a lava flow which is not a huge explosing. However, when the lava is thick, pressure builds up inside the volcanoeo and erupts in a forceful and violent way. This can be extremely destructive. The earth's largest volcano is Moana Loa, down in Hawaii. If this volcanoe is measured from the ocean floor, it is larger than Mount Everest. The volcano, Mauna Loa, is actually what inspired me to post this blog. Over spring break, my family and I went down to Hawaii for vacation. There, we went to see volcanoes and I saw Mauna Loa from a distance. This inspired me to learn about how volcanoes work. I'll post some pictures I took of Mauna Loa. We didn't see it erupt,but could see smake rising, and we also saw a little but of lava on the surface. Wealso saw several guysers near by. Geysers are springs which erupt extremelt hot water. The volcanic heat boils the water underneath and the presure causes the geyser to explode. ( If you've ever seen a kettle explode under pressure, it's probably similar :-) All in all volcanoes are very interesing and I still have a lot to learn. As I learn more, I will continue to add to this post.Links I Used:

Wonder Webs!!!
Ustream.tv, a website established on March 7th, 2007, allows peope from all around the world to interact and communicate with one and other. People can watch live streams, vote in different polls, chat, rate, and much, much more!
Co-founders: Brad Hunstable, Johnny Ham, & Dr. Gyula Feher
Justin.tv is a website, similar to youtube, which also enables you to watch live streaming videos, and users above the age of 18 can broadcast their own videos. Again, this may be a fun website to rome around on just to kill tme.
Facebook: Chat with your friends and family and stay in touch no matter where you are in the entire world!!!
Twitter: Allows you to create conversations, read messages, and reply with your tweets!
This is the first time I've heard of Justin.tv, but just by adventuring the website I feel like it is safer and more appropriate for children to use. Youtube sometimes takes you completely off topic of your search. In my opinion, I found Justin.tv a safer website, but then again, you never know.
Have you ever been really bored and don't know what to do? Well chances are, you probably jumped on your computer and went on to a site like Ustream.tv or facebook. So many websites similar to these have been posted on the web by people all around the world. Ustream, for instance, was founded by Brad Hunstable, Johnny Ham, and Dr. Gyula Feher. These three men had worked on a internet project earlier in 2003. Soon they wanted to be able to communicate with their friends who were in the army. Therefor, these three men startes Ustramer.tv which was available to the public in 2007. Facebook was created by four computer science stundents, Mark Zuckerberg, Eduardo Saverin, Dustin Moskovitz, and Chris Hughes, down in Hardvard Univercity. Now it is the most used social network world-wide. However, are these websites good for you? Do they teach you anything? Should they even be allowed? These websites are a great way to kill time and connect with close friends that you don't see often, but most of us are taking a larger advantage of these sites. For instance, we come home from school after talking to our friends the entire day and then many people go on the computer and start chatting with the same freinds! It sounds ridiculous, but it is most definetely true! That is why sever countries such as China, Syria, Vietnam, and Iran have banned facebook to prevent employes from wasting time using these addicting services. These websites are privledges, but they should not be overused, which they are. Overusing them would only cause negative effects like your grade dropping or employes being fired!
SAFETY?
You also have to remember that if you are not cautious of who you are interacting with on these websites, then these websites could possibly be very harmful. Never talk to strangers, post private information, or pictures of yourself for the whole world to see.
As long as you keep yourself safe and use the privledge sagely these websites are a BLAST!!!
SOME MORE SITES!!!
WOULDN'T TRUST THEM ALL IF I WERE U!!!

Global Warming - Math
Global warming does not neccesarily have to only relate to social studies or science. In fact, global warming is largely based on math aswell. Mathamatical skills are required to analyze what will happen in the future. Scientists need to create line graphs and scatter plots for co2 emittions, population, pollution, climate changes and more over an extended period of time. They could then fit these points to a line and create a linear equation. Extrapolation can be used to predict the effects in the future. You would also need math to calculate personal carbon emmitions or carbon emmitions in your community. The results relate to science and social studies, but the results are found by mathamatics. Statistics, calculating weather (F-C or vice-versa), calculating the rise of sea level, calculation the use of fossil fuels, and creating tables all relate to math. Almost any thing we do can relate to math!!!
