    Aristotle (2500 years ago/4th or 5th B.C.)
    He didn't believe atoms could be constantly moving if they were in a void, he believed that everything was made of fire, air, water, and earth. "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. N.p., n.d. Web. 25 Feb. 2014.

    Democritus (2500 years ago/4th or 5th B.C.)
    He cut a peice of bread in half and then he took that and cut it, eventually you come to a point to where you can't cut it anymore. atomos="uncuttable" and that is how they got the word atoms.

    Dalton (1808)
    TIny little balls and you couldn't make them smaller/pictured the atom as a blueberry muffin "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. N.p., n.d. Web. 25 Feb. 2014.
  • Thomson (1904)

    Thomson (1904)
    He found out they had electrons.The atoms have smaller things. He also saw electrons in the dough in the atom like the blueberries in the dough.

  • Rutherford (1911)

    Rutherford (1911)
    Before, they called the atom the Plum Pudding Atom. Atoms were empty spaced called the nuclear model. "GaggleTube Video - Discovery of the Nucleus: Rutherford's Gold Foil Experiment." GaggleTube Video - Discovery of the Nucleus: Rutherford's Gold Foil Experiment. N.p., n.d. Web. 27 Feb. 2014.
  • Bohr (1913)

    Bohr (1913)
    He had no ideas just like Rutherford but instead of the electrons being anywhere they would orbit. "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. N.p., n.d. Web. 25 Feb. 2014.
  • Heisenburg and Schrodinger(1920)

    Heisenburg and Schrodinger(1920)
    They were buzzing around making different shapes. They didn't really orbit. It would make a certain line. "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. N.p., n.d. Web. 25 Feb. 2014.
