evolution picture

This is a picture that people usually use to describe evolution. It shows that humans came from animals and the how we also involved into always on the computer. That shows that no a days, people spend a lot of time on the computer or other technology things and that is how we are potrayed.

Diet coke and Aspartame
http://www.lightparty.com/Health/DietCokeAspartame.html
Diet coke is really known for the aspartame in it. There are tons and tons of people that will not drink diet coke because of the affects that it will have on your body. The "sweetner" that is used can cause awful things like cancer. This article explains how bad it really is. "Reality is in that twisted Diet coke can. It's poison. It's killing the unborn, raining tumors and seizures on the population, destroying children, incapacitating workers, mimicking MS, erasing memory and blinding. "

How the internet affect students
http://www.medicalnewstoday.com/articles/19387.php
With todays technology there is soo much that teenagers can do on the internet. They can use it for school work, study for tests, and play games. There are now fun websites that serve as huge distractions... just like http://www.facebook.com/ and http://www.dearblankpleaseblank.com/ just to name two. Students get so distracted by these that it can affect their school work as well as keeping them up late at night and not getting enough sleep.

Finals week affect health of students
http://media.www.dennews.com/media/storage/paper309/news/2010/12/08/News/Finals.Week.May.Affect.Health.Of.Students-3965873.shtml
With finals coming up, HBHA students are starting to get very stressed out. Teachers are cramming last minute homework, essays and projects. Even though teachers believe and have the right to believe that their class is the most important because that is their job to teach us...they are stressing out a lot of students. Students are just now getting back assignments and tests that they compleated months ago and are expected to redo them. This is taking over studying for finals and other things going on in high school students lives.
This article is an article about how students get sick and stressed out. Students loose out on sleep, excerize and a lot of other things that are bad on our health.
soo.. good luck on finals..

Fiiireee!
http://www.jpost.com/VideoArticles/Article.aspx?id=197845
We have heard about the very tragic fire that started last week in Israel. The fire is finally contained after many hours, deaths, and evacuations. At first, everyone just assumed it was a terroist attack, but they are now also looking at the fact that Israel is VEeeEERrYYyYyy dry. Having really dry lands, and hot, humid weather, caused a fire...
They don't know the exact cause of the fire, they are still looking into it.

Looottsss offf staarrsss
Astromers have discovered that there are actually triple the amount of stars then it seems. The stars are known as little red dwarfs. Astromers saw that there was a difference between every galaxey. This includes The Milky Way which is our neighbor. The two galaxeys are very differnet and it is because of the difference between the amount of stars.

Jump Rope Aerodynamics
http://www.sciencedaily.com/releases/2010/11/101121195429.htm
Jump ropes can be a lot of fun, and a great source of exersize. But there is a big deal of physics behind how it works. This article explains it. "Our main discovery is how the air-induced drag affects the shape of the rope and the work necessary to rotate it," says Princeton researcher Jeff Aristoff. "Aerodynamic forces cause the rope to bend in such a way that the total drag is reduced." (Leaves do this too when they bend out of the wind.) This deflection or twisting is most important in the middle of the rope and the least at the ends. If the rope is too light it might not clear the body of the jumper.
So the next time you are jump roping, think about the physics behind it, and it could not only be fun and exciting, but you can also learn about physics!!

Baby fat can lead to later health problems
http://www.sciencenews.org/view/generic/id/65981/title/Extra_weight_in_early_childhood_foretells_later_disease_risk
The article states that"Baby fat can be a harbinger of serious disease later on. Being overweight as a young child is a strong predictor of diabetes and heart disease risk in early adulthood, a new Dutch study finds."
This article is about how overweight children can lead to disease in later years. It is interesiing because even from such a young age, doctors can tell what health problems the children are going to have when they get older.
"Although increasing BMI was a strong risk factor for adult disease, being a big baby with an unvarying but high BMI was also associated with higher risk of metabolic syndrome in adulthood, de Kroon says. Weighing too much appears to be bad for adult health, whether a child starts big or merely gets that way during childhood. Moreover, she points out, “if a very thin child is becoming heavier, it may still have a very high risk [of adult disease] even if it never seems too fat.” So even parents of slim kids should watch that children don’t exceed the normal growth curve, she says."

http://www.sciencenews.org/view/generic/id/65742/title/It_came_from_another_galaxy
This is an article about how a planet in the milky way is actually from another galaxy. Sara Seager of MIT, who was not part of the study. “The planet almost certainly formed during the time the star was in the other galaxy.” I think this is pretty interesting because for a long time we have thought one thing but now we know it is something else. This happens a lot in science and it is really cool to watch the changes.

Wanting to know more...
After doing a prezi about cosmology, I wanted to know more. This aritcle explains a lot about theoretical cosmology.

Making a prezi
Right now, our class is working on making prezis. We are making a presentaion about evolution and creationism. The prezi is a really cool way to make a presention. It makes things look super cool and a great way to learn about a subject!
You can make a prezi about anything you want!!

This is a video on a bunch of different optical illusions.
Optical illusions sometimes freak me out! These are really cool though! CHEAK IT OUTTT!
