PRESENTATION OUTLINE

1.

ROBERT ANDREWS MILLIKAN

  • Born in Morrison, IL
  • Studied physics
2.

THEORY

HE WAS TRYING TO MAKE A WAY TO FIND THE CHARGE OF AN ELECTRON
3.

PREVIOUS MODEL

  • The previous model was used with water
  • The drops didn't last long enough
  • They didn't have enough time to find the charge
4.

MAIN EXPERIMENTAL DESIGN

OIL DROP EXPERIMENT
5.

EVIDENCE

  • Set up two parallel plates one on the other
  • Had a mist of oil sprayed into a chamber
  • The droplets fell on to the plates
  • He used the strength of the field and mass
  • Of the drop to find the charge
6.

THEORY EVIDENCE SUPPORTED

ATOMIC THEORY
7.

ATOMIC THEORY

  • Robert Millikan helped invent the atomic theory
  • His oil drop method let people find the charge of an electron
