Atomic Theory Project (50 pts)
Purpose:
To trace the development of atomic theory and to examine how the model of the atom has
changed from the time of Democritus, the discoveries of Dalton, Thomson, Rutherford, Bohr and
Schrodinger (electron cloud model).
Task:
Using the sites provided below, you along with two classmates will present your atomic theory
project in one of the following formats. Each format will be presented orally.
A. Build the following atomic models: Plum pudding (Thomson), Rutherford’s, Planetary (Bohr) and
the electron cloud model (Schrodinger). Include the following for full credit:
• A 2-D or 3-D model for each.
• A typed/double spaced brief written description of each model will be submitted at the time
of the presentation.
• A typed/double spaced bibliography page citing all sources used.
o For a list of sample MLA citations follow this web address:

B. Present the development of the atomic theory (Democritus, Dalton, Thomson, Rutherford, Bohr,
and Schrodinger - Electron cloud).) in a video presentation to the class. The format of the
presentation should be discussed with me in advance. Include the following:
 A 5 min video segment.
 A typed/double spaced description of each model included in the video will be submitted at
the time of the presentation.
 A typed/double spaced bibliography page citing all sources used (See website above)
 A list of the roles of each group member.
C. Compose and perform a poem, rap, or song, explaining how the atomic model has changed
over time with each new scientific discovery.
 A copy of the piece to be submitted at the time of the performance.
 The poem should include all atomic models (Democritus, Dalton, Thomson, Rutherford,
Bohr, and Schrodinger - Electron cloud).
 A typed/double spaced bibliography page citing all sources used (See website above)
D. Develop a timeline to show significant dates and scientists involved in the development of the
atomic theory from early Greek model up to the 1920s (from Democritus to Schrodinger’s current
electron cloud model).
 The timeline must be drawn on a poster board and must include color. Be creative! You
may draw or create 3-D models to go along with the timeline!
 You MUST include all scientists/models discussed in class. (Democritus, Dalton, Thomson,
Rutherford, Bohr, Schrodinger - Electron cloud).
 A typed/double spaced paragraph description of each scientist/theory labeled on the
timeline will be submitted at the time of the presentation.
 A typed/double spaced bibliography page citing all sources used (See website above)
E. Give a short lecture 5-8 min, using power point to illustrate key points, diagrams, and animated
models, on the development of the current model of the atom.


The theories of Democritus, Dalton, Thomson, Rutherford, Bohr, and Schrodinger - Electron
cloud should be included.
Explain the argument used by each scientist as to why his or her model disproved the
previous model.

The following presentation rubric will be used:
1 Point
2 Points
3 Points
4 Points
Amateurs
Rookies
Professionals
Champion Team
Content of
Presentation
Includes some
essential information
and a few facts.
Includes essential
information and
enough
elaboration so
that peers
understand the
topic.
Covers topic
completely and in
depth. Peers
completely
understand topic
and are able to
make appropriate
comparisons.
Oral
Presentation
Skills
Some difficulty
communicating ideas,
due to voice
projection, lack of
preparation, or
incomplete work.
Communicates
ideas with proper
voice projection,
adequate
preparation, and
some enthusiasm.
Communicates
ideas with
enthusiasm, proper
voice projection,
appropriate
language, and
clear delivery.
In addition to
completely
understanding the
topic, presenters
make comparisons to
other theories and
give details of
working conditions
and scientists.
All team members
are involved
enthusiastically in
presentation. Not a
one-player team.
Visual
Information
Model is clear with
some information,
but does not convey
the totality of the
theory.
Model (2-D or 3D) is easy to
gives clear
summary of
essential meaning
of the theory.
Model conveys
complete
understanding of
the theory, both
the accuracies and
shortcomings.
Some type of
technological media
is used to convey a
complete
understanding of the
theory, its accuracies
and shortcomings
For this rubric, the scale is as follows: 10-12 = Champs, 7-9 = Pros, 4-6 = Rookies, 1-3 = Amateurs
