History of the Atom Timeline Project
Introduction
If you were asked to draw the structure of an atom, what would you draw? Throughout history scientists have accepted
five atomic models. Our perception of the atom has changed from the early Greek model because of clues or evidences
that have been gathered through scientific experiments. As more evidence was gathered old models were discarded or
improved upon. Your goal is to trace the atomic theory through history.
Task
You and your partner will research the following scientists associated with the development of modern atomic theory.
Your timeline needs to include a title, names of the scientists, picture of the scientist, a description of their contribution
to the atomic model, pictures of experimental equipment or atomic models. This needs to be creative!
Democritus
Antoine Lavoisier
John Dalton
J. J. Thomson
Ernest Rutherford
Marie Curie
James Chadwick
Max Planck
Niels Bohr
Erwin Schrodinger
Cite Your Sources! (Bibliography goes on the back of your timeline!)
You must hand in a bibliography with your project. This must be in proper works cited/bibliography format. (See the
example shown below.) There are lots of websites that can help you make a correctly formatted citation. One good one
is http://www.easybib.com/
Sample Citation (for an online source):
"A Science Odyssey: You Try It: Atom Builder." PBS. PBS, 1998. Web. 04 Nov. 2009.

Research Tips
Some of these scientists did experiments not related to atomic theory as well. If you search on the web
form information, you might include searches about history of atomic theory, or “Niels Bohr atomic
theory” to help get less broad results. You can of course get good information by searching each name as
well, but don’t forget to find out about contributions to atomic theory. Your textbook also has useful
information about some of these scientists.
Here are a few useful websites to get things going.
