| Ms. Kennens's Chemistry Webquest |
| Atomic Theory Time Travel Mission |
| Introduction: |
| The American Chemical Society
has chosen YOU! You
and your partner will be traveling back in time in order to meet the
Greek philosopher Democritus. Democritus first introduced the
concept of atoms thousands of years ago. Since then, our
understanding of the atom has slowly expanded up until today. It is
your job to bring him up to date. You must communicate to him how our understanding of the atom progressed through history. What were the key steps in the development of that understanding? This is what you will be investigating in this Webquest. |
| The Task: |
| You are to develop a briefing for Democritus that outlines the key scientists and experiments associated with the development of modern atomic theory. The briefing should include the names of the scientists, a description of the accomplishments, pictures of experimental equipment or atomic models, and descriptions of important scientific laws or principles developed by these scientists. |

| The Process: |
| 1. Read over the
entire webquest!!!!!!! 2. Begin your research by using your textbook and the links provided in the resource section of the webquest to complete a research data sheet for each of the following 22 scientists, experiments, and atomic models: - Democritus Millikan Lavoisier Bohr Proust -Thomson Chadwick Rutherford Moseley Dalton -Gold Foil Experiment Schrodinger Mendeleev Marie Curie -Cathode Ray Tube Experiment Law of Conservation of Mass -Law of Definite Proportions Dalton's Atomic Theory -Plum Pudding Atomic Model Rutherford Model -Bohr Planetary Model Quantum Mechanical Model 3. Prepare a chronological briefing for Democritus (assuming you can bring a PC back with you) using PowerPoint or Word. It should include information from your research data sheets presented in chronological order and pictures to illustrate your information. Refer to the grading rubric for a detailed outline of the requirements. 4. Make a timeline as part of your briefing which presents an overall view of the information. |
