Storyboard Text

  • Democritus
  • I don't believe that atoms are made of small objects, they are made of fire,water,wind, and Earth. I also believe that atoms have no empty space.
  • Matter is made of small, solid objects that cannot be divided, created, or destroyed. Also known as an atom. I also believe in empty space between atoms.
  • Aristotle
  • I agree with Democritus that atoms cannot be destroyed, created, or divided. I've made a atomic model to prove it. I believe it's a smooth sphere.
  • John Dalton
  • J.J. Thomson
  • I did an experiment called Cathode Ray Experiment. I found that opposites attract. So the Cathode ray bends towards a positively changed plate or in other words electrons.
  • I also made an atomic model called the cookie model which is a positive sphere with negative changes.
  • Ernest Rutherford
  • I did a gold foil experiment where I shot a positive particle beam towards a piece of gold foil. SOme beams bounced back which means alikes repel or in other words protons
  • I discovered the nucleus which had neutrons which are not positive or negitive.
  • I discovered that electrons move in circular orbits. I also believe that electrons further away have less energy than the ones closets to the necleus.
  • My atomic model is a circular model that has electrons and a necleus.
  • I found that electrons dont move in set paths but in waves. My atomic model is a wave model.
