=**It's a Wiki Challenge!**= Each POGIL group will be assigned a particular "model" or prior idea of how scientists viewed the atom. As a group, your goal is to create a useable wikipage on this site which addresses the following:

(1) Identify the timeframe and context around the model in question. Include (cite your source!) an image of the model of the atom, and clearly describe the parts of the atom included in this model.

(2) Describe the experiment(s) that led to the development of this model. How did evidence change the model of the atom compared to the previously accepted model?

(3) Considering the modern view of the atom, what are the shortcomings of this model?

Group 1: JJ Thomson

Group 2: Ernest Rutherford

Group 3: Niels Bohr

Group 4: Modern Atomic Theory
