1. The Atomic Theorists

2. J. J. Thomson ( )
Thomson is credited with the discovery of the electron (using the cathode ray experiment), of isotopes, and the invention of the mass spectrometer.

3. Earnest Rutherford (1871-1937)
Rutherford pioneered the “Rutherford model” of the atom, through his discovery and interpretation of Rutherford scattering in his gold foil experiment.

4. Robert Millikan ( )
American experimental physicist who won the 1923 Nobel Prize for his measurement of the charge on the electron and for his work on the photoelectric effect

5. Niels Bohr ( )
Danish physicist who made fundamental contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in 1922.

6. Project #1 (100 pts, due 9/24):
You and your group will write and perform a short play based on one of the experiments performed by the atomic Theorists; Thomson, Rutherford, Millikan, Bohr. The play should be three to six minutes long and everyone in the group should have a role.

7. Project #1 (100 pts, due 9/24):
Your project should include the following elements:
Props, pictures and/or other visuals of the experiment
Explanation of how the experiment or theory worked
Why it’s scientifically significant
Background of the Scientist

8. Project #1 (100 pts, due 9/24): The Rubric
A portion of the grade for the project will be based on the input of a panel of peers who will assess both the project and the student's presentation of their project.
