Symbiotic Relation

Symbiosis a a close relation between to organisms which is beneficial to atleast one of the organisms. The three different types of symbiotic relations are mutualism, commensalism, and parasitism. Mutualism is a relation in which both species benefit. Commensalism is when only one of the species benefits however, the other organism is neither harmed nor helped. Lastly, parasitism is when an organism lives in or on an other sprganism and the other organism is harmed.
The picture on the right is some poison ivy I found on a tree, in my backyard. (Remember, "Raggy rope, Don't be a dope!"). Poison ivy is an example of a mutualistic relationship. For example, poison ivy is a defense mechanism for a plant or tree because it drives away predators. In turn, the poison ivy feeds on the tree and recieves nutrients.

Biotic Limiting Factor

The picture above is a biotic limiting factor found in my community. I will comment to the name of this plant once I find out. This plant is a living factor because during the summer, there are flowers which are pollinated by bees and other insects. The leaves are also eaten by other animals such as deer. In addition, the plant is home to populations of insects, bugs, and worms in the soil. Plants also needs several abiotic factors to survive. For instanse it needs, oxygen, water, sunlight, a proper temperature, and soil. These are the only five natural abiotic factors that exsist in this entire world.

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!!!
