"The opposite of a correct statement is a false statement. But the opposite of a profound truth may well be another profound truth." Neils Bohr

Creating an Atomic Model


The discovery of the atom as we know it today was a progression, like the discovery of DNA or any other major scientific discovery. Many scientists contributed to the development of present day atomic theory. Each proposed model of the atom was based on the models developed prior to it. With each new discovery dealing with the nature of the atom, a new atomic model was constructed. The first person to believe in the existence of the atom was Democritus in 400 B.C.

Your Task

Make a model of each progression of the atom listed below.
Write a brief description to go with each model explaining the various components
Present the models to the class for peer review

Be sure to include a list of resources used to complete your project (i.e. web sites, books)

This project will count as one test grade (100 pts) for the 2nd quarter.
Grading Considerations (see peer grading sheet)
1. Accuracy of information
2. Appearance of models
3. Creativity
4. Presentation of models to the class
