Storyboard Text

  • HI there, my name is Democritus and it is the year 450BC. there are many different conspiracy theories but I believe that everything is made up of very small spheres called atomos.  
  • My name is John Dalton and it is 1803, it has been over 2000 years since Democritus published his idea about atomos and I agree with his theory! Atoms make up the world however they cannot be separated but can be joined together to form everything in the universe. 
  • Hello I am JJ Thomson and i have recently discovered electrons, i clearly understand that they are spread evenly among the atom. i have called it the plum pudding model because it reminds me of my favourite my pudding!
  • it is 1907 and I Earnest Rutherford discovered the nucleus and the protons within it.  I found this out by the gold leaf experiment firing alpha particles at a gold sheet of paper.
  • i am Neils Bohr i managed to figure out that the electrons orbit the nucleus in a fixed circle called shells.
  • Hello! i am James Chadwick and i discovered neutrons in 1932. And i also found out that hey have the same weight as protons!
