Science: Class Response

Three Facts :

1.) Electromagnetic Spectrum is the complete range of electromagnetic waves placed in order of increasing frequency.

2.) Radio waves are the electromagnetic waves with longer wavelengths and lowest frequencies.

3.)Infrared Rays are electromagnetic waves with wavelengths shorter than those of radio waves.

4.) Visible light is electromagnetic waves you can see.


My opinion on this is that it's fun to learn about the electromagnetic spectrum. I didn't remember a lot about the spectrum, and it was a nice brush up on it. I also learned that an example of infrared rays is a heat lamp because it gives off infrared rays. An example of a radio wave is not only a radio is when a broadcast station sends out radio waves, and we can hear it on our radio or television. Below are websites about this topic:

Social Studies: Inauguration Of Obama

A brief summary of this topic: The topic being shown in my blog is about President Barack Obama's inauguration. I have found two articles including different pieces of information concerning the historical event. This year thousands and I all around the world are going to be able to witness how our nation has evolved, forming extreme togetherness. Below, I am going to show the two articles I read.

Article #1: In this article the brief summary is the journalist is describing the how the first lady and our President are very excited about finally reaching their destination: The dream of the first African American president of our nation. In the article I found the first paragraph appealing it says, ""At Last" may have been just what President Barack Obama and his wife Michelle were thinking Tuesday night as they glided through their first inaugural dance to the Etta James classic." I found this quote appealing because it shows how long the Obama's had waited for the moment to come where they could transform the nation into a more developed one. My overall thoughts about this article is that it was interesting to read about the excitement that went on after Obama was officially inaugurated, and this article also shows me how much his family means to President Obama.

Article #2: This article is describing the actual inauguration. The inauguration was extremely exciting and a heartwarming situation, after all, this was history in the making. To stand and watch an African American man take oath to lead our nation was simply emotional and, to some, unbelievable! In fact in the article it states, " In his speech, Mr.Obama acknowledged that the changes his presidency represented describing himself as a 'man whose father less than sixty years ago might not have been served in a restaurant.' But although the crowd and the podium around his were full of elated African Americans, Mr. Obama, the first black to become president, did not dwell on this in his speech." It is so shocking to know that our nation was once a nation full of prejudice people, yet it is very comforting to know that our nation has come a long way. So long that it is now being led by an African American.

My overall thoughts on this topic is that I am exceptionally inspired by this movement in history, and although we cannot ignore what had occurred in the past it is soothing to know that we can get passed the prejudice and racism and form a nation where everyone is known to be equal. I wonder how these four years will be like, and what will happen. I also wonder if our new President will carry our nation out the financial crises. I predict that his four years of presidency will change America forever.

Class Response: Waves

Three facts I have learned in class:

1.) A transverse wave is a wave that move the medium at the right direction in which the waves travel.

2.) A longitudinal wave is a wave that moves the medium parallel to the direction in which the wave travels

3.) The high point of a wave is called a crest, the low part is called a trough.

4.) A medium is the material through which a wave can travel through.

My opinion on the subject of waves is that it is interesting to learn about. I didn't know that a wave that needs a medium to travel through is called a mechanical wave. Examples of a medium could be water, air or any type of solids like a rope. I didn't know that light from the sun can carry energy through an empty space. The opposite of a mechanical wave is a electromagnetic wave which doesn't need a medium to travel through. Below is one website that includes the definition and plenty examples of waves, crest, and troughs.
