Revised: 2/2003

 

Introduction

The Modern Atomic Theory wasn't developed from one scientist's research. Instead many scientists over the centuries contributed to the development of the atomic theory. Each of the scientist's theories built upon the previous ones due to the advancements in technology of that time.

 

Task

1. You will become an expert on one of the atomic theories.

2. You will present your knowledge to your group.

3.Your group will do a joint oral presentation to the class.

 

 

Roles

1. Democritus and Dalton

2. J. J. Thomson
3. Rutherford
4. Bohr

5.Modern or Wave

 

 

 

Process

1. Every member of your group of 5 or 6 will pick one theory to research. (Honors classes will also research -New Theories) You may use the links below or others.

2. Take handwritten notes on your theory (cite your sources). You must also research the theory before and after yours so that you can understand how your theory developed and how it impacted the next theory.

3. Create a visual to help others understand your theory.

4. Explain your theory to your group. Include any experiments and modern developments that led to your theory. Explain how your theory built upon previous theories and how it impacted subsequent theories.

5. Your group will plan an oral presentation of the theories. This can be in the form of a skit, debate, news broadcast, etc. Creativity will count towards your grade.

6. Rehearse your presentations on your own.

7. Present your group's oral report.
