Atomic Theory/Periodic Table History Timeline
Make a timeline of Atomic History
 Use Computers-Need to work in groups of 2 but everyone needs to make their own copy-QUIZ
GRADE
 Use the list of names and topics below to help
 Briefly explain how each scientist contributed to the Atomic Theory (some have multiple
contributions so include all of them)
 You need at least 3 sheets of computer paper, a ruler, and a couple of pieces of tape
 Definitions/Descriptions should be written on a separate sheet of paper
Scientists to include:
1) Aristotle
2) Neils Bohr
3) John Dalton
4) Louis de Broglie
5) Democritus
6) E. Goldstein
7) Werner Heisenberg
8) Antoine Lavoisier
9) Dmitri Mendeleev
10) Robert Millikan
11) Henry Moseley
12) Max Planck
13) Joseph Proust
14) Lord Rutherford
15) J.J. Thomson
Topics to include: all definitions, descriptions, etc. should be written on a separate sheet of paper and
then stapled to Timeline
