Atomic Theory Time-Line Project
Using the information from your text book, class room discussion, “Atom” chapter and additional sources you find to
construct a time line of the events that lead to our current understanding of the atom.
Required information for each person
 Person’s name
 Year (of the discovery or the year they lived)
 Must include answers to the questions below:
o When did they live? Where did they live?
o What new information did they contribute to the understanding of the atom?
o How did they find this new information? (What experiments did they do?)
o Interesting facts – other accomplishments, personal information, famous historical events at the time, etc.
All Projects are due Wednesday September 25, 2013. *Students must include their rubric when assignment is turned
in order to be on-time.
The time line project should start with the Greek philosophers that you read about in the “Atom” chapter. It may continue up
to present day scientist and their experiments and should provide us with additional insight or understanding of the atom.
Helpful Sources:
Chemistry textbook
In class notes and handouts
On-Line sources [search “History of the Atom” or “Atomic Theory History”]
People you must research:
Required persons and must have their atomic model in presentation
Democritus
Niels Bohr
JJ Thomson
John Dalton
Ernest Rutherford
Erwin Schrodinger
James Chadwick
Helpful hints:
 If one person had several contributions at different times in history they will count ONLY once for this
project. You may have them in your time line more than once but they will only count once.
 The project can take MANY different forms. For example
o A photo/scrap book
o A blog
o A face book page
o A flip book
o Animoto
o Prezi
o Glogster
o Be creative, but the scientists MUST be in chronological order.
 Sources must be sighted, copy and pasting paragraphs of information is plagiarism and students will receive a
zero for the assignment. Remember to pick out the most important, unique, and most interesting contribution
the people had.
All rubrics are due are due on the day assignment is turned in!!! Projects are due Wednesday September 25, 2012.
