Hey, im Aimee. I am in Miss Baker's Biology class and its pretty sweet. Our class is really cool becuase we do fun and creative experiments. I like our class because it is interesting. My favorite thing that I have learned about so far has been making and learning about cells. We made the cells out of a goopy substance that looks like this... http://www.flickr.com/photos/kaszeta/147065012/We timed how long the cell we designed would take to change from red to yellow by putting it in a cup full of vinigar. This experiment helped demonstrate diffusion. The thinner cells changed to yellow the fastest because when a cell is very thin,flat, and narrow it can obtain nutrients more quickly.I also learned that even though cells that are thin make it easier to obtain nutrients, but since they are so fragile they can be easily damaged or destroyed which is a disadvantage of their shape.In my free time i like to hang out with my friends and do gymnastics. :)

Student Expectations
How Will I Meet This Expectation?
How Did I Meet This Expectation?
Demonstrate ability to
evaluate sources of
biology information on
the internet

by using credible sources for my posts
finding internet sources that end in .edu or .gov
checking my classmate's sources
l having at least two credible sources
I added my www.efluxmedia.com website to the credible sources page so that it can be approved by my peers.

I did a post using livescience.com because it was accepted my many classmates including miss baker on the credible sources list.
Demonstrate an ability
to read and understand
current biology news
going over information from a credible source
making sure I understand the information I read
chosing eye-catching topics that my classmates will enjoy reading
I put the informatiuon that i read off off efluxmedia.com and put it into my own words.

Also, I was able to put the information from livescience.com into my own words because most of it was pretty simple reading but I did not understand some words, like Sphenodontia, which i then looked up and found out that it was a name for a branch of prehistoric dinosaurs and the tuatara is the only animal still living animal in that branch.

Since so many people have been getting sick lately and it is cold season i thought it would be interesting for my classmates to know that the amount of sleep they get could change their health situation.
Demonstrate proper
use of online resources

using scientific sites
changing the sources words into my own
using sources that are up to date
making sure my sources are credible
While writing my post I used two different sources, http://www.efluxmedia.com/news_Too_Little_Sleep_May_Triple_The_Risk_Of_Catching_A_Cold_33262.html and http://www.sciam.com/blog/60-second-science/post.cfm?id=can-a-good-nights-sleep-prevent-a-c-2009-01-12 that were both reliable and up to date.
I also used a picture for my post that was creative commons approved.
Publish work that is
available for peer-review
making sure I post my blog on the wiki so my peers can review it
useing creative commons pictures
I posted my blog on the wiki for peer review & included a
creative commons picture in the post.
Discuss published work
with a practicing biologist
in that particular field

making sure that the information I am being given is reliable and the scientist
has experience in that feild
having other review my post to make sure it is accurate and reliable
The scientists that were on the websites I used were reliable and certified,
therefor I was sure their information would be accurate and helpful.

I wrote an e-mail to Mr. Zivkovic from www.scienceblogs.com and asked him a question pertaining to my post on the tuatara.
Provide constructive
peer-review to
critiquing my classmates in ways to help
accepting any comments made about my posts
giving my classmates opinions that wil help them
I commented on Jenna's post "Girls help boys focus", Jeremy's post "Im not blind I just can't see", and Makarios's post, "Is it a bird, a plane, not its a dinosaur!"
I commented on "Genetics of Race Assignment" and discussed how I felt towards the test we were assigned to take on racism.
I critiqued skyes post "Snake Discovery" on her discussion board.
I critiquedcaitlins post on vitamin d on her discussion board.
I critiquedmary's post about DNA being able to be repaired when damaged on her wiki.
Discuss in-class

making sure that some information in my post relates to what we have learned in class
I wrote a post about the tuatara which is the fastest evolving animal because in class right now we are learning about evolution, I thought that this would be a legitament topic to write on.
Apply creativity
to work
using pretty and interesting pictures off of creative commons
trying to make a video on a website
I made a pollon polleverywhere.com

I made a bitstrip about my second post on the tuatara.

Too Little Sleep Can Triple The Risk Of Catching A Cold

Have you noticed that you are the type of person who gets a lot of colds? Do you notice how much sleep you get every night? These two things could be related. In a
recent study it is shown that people who get less then seven hours of sleep a night are three times more likely to catch a cold then those who get eight or more hours. Researchers believe that lack of sleep can cause immune dysfunction, which can make people more likely to catch common colds. It makes a big difference when you change the amount of sleep you get.
Also, lack of sleep can activate changes in a persons’ immune system that can make a person more vulnerable to get an infection. As an example, when you do not get enough sleep, the number of T-cells in your body drops. Killer T-cells are cells that help destroy viruses and bacteria, as well as lower levels of protein. This study links loss of sleep and the chance of catching the rhinovirus, a main factor behind the common cold.
this article it shows scientists studied 153 healthy men and women between ages 21 and 55 that would allow themselves to deliberately catch the rhinovirus. For two weeks scientists kept a close eye on the quality of each persons rest and the time they went to sleep, without the cold. Then, the men and women were put into his or her separate hotel room and given nasal drops with rhinovirus in them. The scientists then kept track of how the rhinovirus drops had affected them the amount of congestion, sneezing, runny nose, and mucus accumulated in five days. The results showed that people who slept for more then eight hours were 2.9 times less likely to develop a cold. Also, the participants that had a better nights rest, no tossing or turning, were less likely to get sick. From this we learn that both sleep amount and efficiency are important.
Sheldon Cohen, who has studied susceptibility to viruses for thirty years says that sleep loss in only one lifestyle factor that can contribute to catching the common cold. Another is stress, which can harm immune systems and increase risk of catching colds.
It also states in this article, that a survey by the National Center for Health Statistics discovered an estimated 50 to 70 million people suffer from sleep loss or sleep problems. Also, 33 percent of those who slept less than six hours were obese, as were 26 percent of those who got nine hours or more. Only 22 percent of those sleeping the recommended amount of time were obese.

Do you get the recommended amount of sleep a night? Can you find anything else that might sleep loss might lead to?

what do you guys think of my post?
Jordan- I am not so sure about the use of your second link. I feel it is unable to be completly trusted due to the slang used and the advertisments shown. I think there is a writing problem: Researchers believe that lack of sleep can cause immune function, which can make people more likely to catch common colds. I also made a spelling correction.
Reply to review made by Jordan- I believe that my second link is a good website because of the information given on this website... http://www.efluxmedia.com/page-about_us.html if you read this and still have problems with the website please notify me, also thank you for making the spelling correction (:
Will B- I disagree with Jordan these sites seemreliable to me, they have links to other related articles, and the authors name stated. I understand with what made Jordan skeptic because the ads do not make it seem very crediable, however the second link has been approved by students and Ms. Baker.
Mary-- I also agree with will and I think that your sources seem pretty reliable,but I would try to find another website because one of your sources seems a little unreliable.Other than that I think Jordan has covered all the corrections so all I have to say is great post!
Hope~I disagree with Jordan because the second source was on the credible sources page on the blog. You should put at least one more question up there. Besides that iot is a very good post with reliable sources

Fastest Evolving Animal

The Amazing animal called the Tuatara is an animal that does everything slowly; they grow slowly, reproduce slowly, and have a very slow metabolism. But, these animals do not evolve slowly, in fact, they are said to be the fastest evolving animal. These creatures look similar to lizards and live only in New Zealand. They are said to live for almost 100 years and are the only animal that is not extinct in the Sphenodontia that lived in the dinosaur era.
In order to find out the evolutionary speed, researchers tested DNA from the bones of an ancient tuatara. The researchers found out that even though the animal hasn’t drastically changed over a long period of time, it is evolving at a rapid DNA level. The DNA levels were evolving faster then any other animal.
Researcher David Lambert from the Allan Wilson Centre for Molecular Ecology and Evolution in New Zealand states that the tuatara has the highest molecular evolutionary rate that anyone has measured.
Many previous scientists have thought that evolution would be fastest in animals whose physical features evolved quickly as well as their DNA levels but the tuatara shows otherwise, there is no relationship between the two rates.
TheAdélie Penguins, which Lambert and his team have also studied for many years have an evolution rate that is slightly slower than that of the tuatara. The tuatara’s rate is crucially faster than four other animals that have also been studied, the lion, ox, horse and the cave bear.
This information will be helpful for future study and conservation of the tuatara. Lambert’s team is now looking into the evolution of other animal species. Also, Lambert wants to go on and measure the rate of molecular evolution for humans.

bitstrip here :)

Do you know any other animals that evolve as quickly as either the Tuatara or the Adélie penguin? How else can we use this information for science?
