Atomic Theory Project (100pts)
Purpose:
To trace the development of atomic theory and to examine how the model of the atom has changed from the time of
the Democritus, the discoveries of Dalton, Thomson, Rutherford, Bohr, Millikan, Chadwick, Bacquerel, and
Schrodinger (electron cloud model).
Task:
Using the sites provided below, you along with one or two classmates will present your atomic theory project in one
of the following formats. Each format will be presented orally.
*********************All project formats must include an APA reference section! *********************
 For a list of sample APA citations follow this web address: http://owl.english.purdue.edu/
Project Formats:
A. Build the following atomic models: Dalton’s, 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.
B. Present the development of the atomic theory in a video presentation to the class. The format of the presentation
should be discussed with me in advance. Include the following:
1. A 5 min video segment.
2. A typed/double spaced description of each model included in the video will be submitted at the time of the
presentation.
3. A list of the roles of each group member.
C. Compose and perform a poem, rap, reenactment, or song, explaining how the atomic model has changed over
time with each new scientific discovery.
1. A copy of the piece to be submitted at the time of the performance.
2. The performance should include all atomic models (Democritus, Dalton, Thomson, Rutherford, Bohr, and
Schrodinger - Electron cloud).
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).
1. 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!
2. You MUST include all scientists/models discussed in class.
3. A typed/double spaced paragraph description of each scientist/theory labeled on the timeline will be
submitted at the time of the presentation.
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.
1. The theories of Democritus, Dalton, Thomson, Rutherford, Bohr, Millikan, Chadwick, Bacquerel, and
Schrodinger - Electron cloud should be included.
2. Explain the argument used by each scientist as to why his or her model disproved the previous model.
Grading:
The project will be a total of 100 points. (80 pts for the project, 20 pts for the presentation) Your project will be
graded on the following areas:
 Quality of information (50 pts)
Creativity (20 pts)
 Group participation (10 points)
*All video projects will be shown in class. All songs/poems/raps will be recorded and all other projects will be
displayed in the room! ☺
