SO...WHO'S AN ATOM?

        Who's an atom? I think you mean what's an atom. Well, if you want to know, read my previous blog. I ain't gonna repeat it. No, why I'm doing this 'learning' stuff today is because Mr. Sellers is makin' me. So, what I'll teach you today is who discovered atoms. Before we start, I want you to know that I'm not enjoying this, so don't be surprised if it's boring.
        Anyway, atoms weren't discovered by only one person. The first one we'll learn about is Democritus. Here...
         
        Yeah, I know. He's not the most good-looking person in the world....(Anabel changed my wording. It was originally 'He's ugly'.) haha anabel was here. Fatima: Ignore that. Whoops...urgent call, unavoidable. So, since I can't teach you anymore about what's-his-name (thank God), I'll let Bill take over. Here he is:
        Yes, I know he's a bird. But that's not the point. The point is, you wanted to learn about who discovered atoms, and since I can't teach you, a bird will. Now, if you don't want to be taught by a bird, exit this blog. Please, it will save me a lot of time. Got a problem? Good. Quit complaining. So... see ya.
        Hezo. Bill here. Okay...Democritus formulated an atomic theory for the cosmos. Lotsa people consider Democritus to be the 'father of modern science.' He said: "Atoms are infinite in number and imperceptible because of the minuteness of their size".
        The second person we'll learn about is Dalton. John Dalton. Dalton, or John, was an observer of weather and a discoverer of colorblindness. It was in the early 1800's when Dalton, or John, came up with his atomic theory. His atomic theory stated that elements consisted of tiny particles called atoms. He said that the reason an element is pure is because all atoms of an element were identical and that in particular they had the same mass. Dalton, or John, also said that the reason elements differed from one another was that atoms of each element were different from one another. In particular, they had different masses.
        Next up is... oh, Fatima's back. Finally. I was beginning to get bored. Yes! Whoo hoo! Back to the skies.See ya, wouldn't wanna be ya!
        Hi. I'm back, unfortunately. It was a false alarm. It was...oh, don't make me rant. Now, where was Bill... did what's-his-name... did Dalton, or John... ah, yes.  Next up is Avogadro, whoever that is. I guess I'll have to find out. Oh, did Bill show you any pictures of Dalton, or John? Here's one:
        Just a bit better than Democritus, but not by much. Yes, okay. Next up: Amedeo Avogadro. Avogadro published an article in Journal de physique that had the distinction between the molecule and the atom. He pointed out that Dalton had confused the concepts of atoms and molecules. The "atoms" of nitrogen and oxygen are in reality "molecules" containing two atoms each. Thus two molecules of hydrogen can combine with one molecule of oxygen to produce two molecules of water.Avogadro suggested that equal volumes of all gases at the same temperature and pressure contain the same number of molecules which is now known as Avogadro's Principle. Picture:
       








 
 
 
He's worse than Democritus and Dalton, or John. But forget that. Yay! We're done! Feel free to... celebrate good times, come on! Sanks for reading. Well, until next time.

The Atoms Family

               Today, class, we shall be learning 'bout atoms and(drum roll please)elements! As you know, every good teacher learns from their students. Anyone know what atoms and elements are? Anyone? Please? Pretty please? Oh, I suppose I'll have to look it up. *Sigh*. And I thought you people were smart...don't look at me like that! I was only joking! Jeez!               
              Okay, even though I'm so not enjoying this, I'll try to add some 'pizazz' in this. Here, I'll make a list:
  • atom- the smallest unit of an element that still can be identified as that element.
  • proton- a subatomic particle that has a positive electric charge.
  • nucleus- center of every atom that contains at least one proton.
  • neutron- a subatomic particle that has a negative charge.
  • atomic number- the number of protons in an atom.
  • element- a substance that contains only one kind of atom.
  • metals- conduct heat and electricity.
               Yeah, I know, boring right? Wrong! It's actually pretty interesting if you interested in the body. I'm not saying that I am interested, but it's still pretty interesting. Check out these pictures:
But there are all these cool songs and stuff. If you want to watch the videos, look down. My point is, never judge a book by its cover. These may look boring, but they really aren't.

Electricity!


     Electricity is, in my opinion, one of the most important invention in the world. Electricity is used to power the light bulb, the oven, the microwave, the stove, air conditioning, computers, television, exercise equipment, and outlets. Without electricity, our only source of light would be fire. We would have to cook our meals by fire. There wouldn't be frozen microwavable meals. There would be no television, no computers, no game systems, and no phones. The only thing we'd have to do is read, not that I'm complaining. Our lives would be totally different. On the other hand, electricity can be dangerous. Very dangerous. Power lines can fall. Electricity can cause fire. Then again, everthing has its ups and downs.
