Class Response Science Blog

Right now in science class we are learning about refraction, reflection, and the electromagnetic spectrum.

Refraction is when energy changes speed as it travels from one matter to another causing the energy to change direction. Refraction only happens when the energy hits the new matter at an angle. This is why it is hard to continue riding a skateboard in a straight line when you go from riding it on the sidewalk to riding it on the grass. This is also why images appear to be broken when they are partially under water and partially in the air.

Reflection is when an image reflects off a surface back into your eye reflection happens every time you look into a mirror or any reflective surface.

The electromagnetic spectrum is the range of all the possible radiation frequencies. It includes radio waves, microwaves, infrared rays, visible light, ultraviolet rays, x-rays, and gamma rays. Radio waves have the longest wavelength and gamma rays have the shortest wavelength. Visible light takes up only a very small portion of the electromagnetic spectrum but it is the only part of the spectrum that our eyes can see.

Social Studies National Blog- Presedential Inauguration

On Tuesday November 20th president-elect Barack Obama was inaugurated. At the National Mall Obama made his inaugural address and took the oath of office officially becoming the president of the United States of America. Then there was a parade then an inaugurational ball. President Obama is the first African American ever to become president so this was an extremely important moment in history.

President Obama gave an well written and very inspiring inaugurational address. It was really nice that he mentioned helping poor nations because I think that charity is important. One of my favorite lines from his speech was " Today I say to you that the challenges we face are real, they are serious and they are many. They will not be met easily or in a short span of time. But know this America: They will be met." I liked this quote because it shows that he plans to do something about the crisis America is in and I think that it was really well said. I also think it was good that he mentioned some of the things he planned to do for our country because they were all good ideas. He also mentioned the problems America has to face and that "This is the meaning of our liberty and our creed, why men and women and children of every race and every faith can join in celebration across this magnificent mall. And why a man whose father less than 60 years ago might not have been served at a local restaurant can now stand before you to take a most sacred oath." because these are important parts of his presidency. All in all, Obama's speech was well written and very inspiring.

On Tuesday January 20th in front of about one and a half million people Barack Obama officially became president of the United States of America at the National Mall. Obama is the first African American president and has huge challenges to face. but Obama says that America will get through the tough times and that "Greatness is never a given. It must be earned." The crowd at the National Mall was so huge that some people were more than a mile away from the swearing in ceremony and had to watch it on huge televisions all over the National Mall. This is a huge and important event in America's history

In my opinion the inauguration of president Obama was important event in our history and it is wonderful that we finally have an African American president. I also think that Obama's speech was really good, inspirational, and well written. I know that Obama has many challenges to face and I hope that he solves them. I think that Obama is going to be a great president.

Nowadays designers are incorporating technology in to their clothing more and more often. An example of this new technology is the M-Dress this dress doubles a a telephone and when it rings you raise your hand to answer the phone. This dress works with any standered SIM card and was produced by UK firm CuteCircuit. Jane McCann who is the director of Smart Clothes and Wearable Technology at the University of Wales predicts that in the near future clothing could have functions such as helping you find your way somewhere, telling you how fit you are, telling you where someone is, or telling you whats on at a museum or club. She also says that while the fitness industry has made alot in the way of wearable tachnology the fashion industry is lagging behind. McCann also predicts that custmization will become popular. Thefashion industry typically uses technology for looks not function. All in all, in the next ten years clothing could be for alot more than just wearing.
