This lesson is for Mrs. Bryan's ninth grade physical science classes. This lesson, The History of Atomic Models, corresponds to chapter five section one from our text book. Specifically, this lesson is about five scientists and their contributions to the atomic model, as well as the currently accepted wave model. The scientists we will study include Democritus, John Dalton, J.J. Thompson, Ernest Rutherford, and Neils Bohr. The important concept here is that no one scientist created the entire "picture" of the atomic model. Instead, each person added a "piece" to the model, or puzzle if you will, using the scientific method. Remember, the model is still in progress. You may be the next scientist who adds another "piece" to the atomic model "puzzle." The scientific method is a never-ending cycle.
Here are some other sites to visit that explain the same material from the History of Atomic Models. Other scientists are also included in these sites.
Be sure to visit the related project link. Your project is due 2/10/01. The first related web site links you to a page where you may find many other links with more detailed information. The second related web site also provides more information about many scientists. The second link is my favorite.
