Ch. 5 Project – Atomic Model
To help you piece together the story of what we know about the
"atom", you will be creating a timeline depicting the development of
the scientific model of the atom. It has been through new discoveries by
philosophers and scientists in physics, as well as chemistry, that the model of
the atom has expanded and changed over time. Your assignment is to research the
major contributors and significant discoveries that have impacted the atomic
model and, from this material, develop a timeline.
the development of models of the atom to the present and describe how each
model reflects the scientific understanding of their time.
L3. Make and use appropriate symbols, pictures,
diagrams, scale drawings, and models to represent and simplify real-life
situations and to solve problems.
Your timeline MUST:
- Include AT LEAST the following scientists/groups:
- Albert Einstein
- Aristotle and fellow greeks
- Hans Geiger
- Robert Millikan
- Murray Gell-Mann and
- James Chadwick
- Antoine Lavoisier
- Charles Augustin de Coulomb
- Max Planck
- Sir William Crookes
- Ernest Rutherford
- Marie and Pierre Curie
- Erwin Schroedinger
- John Dalton
- J.J. Thomson
- Glen T. Seaborg
- Otto Hahn, Lise Meitner
- W.K. Roentgen
- Include the following
pictorial models of the atom in their correct place on the timeline:
- indivisible, solid sphere model
- electron cloud model
- planetary or solar system model
- plum (raisin) pudding model
- the Bohr model
- Be chronological in its sequence, with
the dates clearly shown. You do not have to follow the typical
horizontal timeline format; you may be creative and use any format you
- Contain, through pictures and/or
explanations, the significant contributions and experiments of those
scientists and atomic models listed above.
- Be neat and legible.
OTHER IMPORTANT NOTES:
- You may find other atomic theory
timelines or student projects online. You may use these as a guide,
but your project MUST represent original research. We will spend
some class time doing research.
- No late timelines will be accepted and
this project counts as one test grade.
Your timeline is due on
