Atomic Theory Time Travel Mission
Introduction: The American Chemical Society has chosen YOU! You will travel back
in time 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. It is your job to bring him up to date. You must communicate to him
how our understanding of the atom has progressed through the ages. What were the key
steps in the development of our understanding of the atom? This is what you will be
investigating through this web-quest project.

The Task: You are to develop a timeline for Democritus that outlines the key scientists
and experiments associated with the development of modern atomic theory. The timeline
should include the name of the scientists, their pictures, a description of their
accomplishments with particular attention to the contribution the scientist has made
toward our knowledge of atomic theory, pictures of experimental equipment and their
version of the atomic model, if applicable.




The Process: 1. Read over the entire web-quest!!!!

              1. Begin your research by using your textbook and the websites provided
                 in the resources section of the web-quest (or other websites) to
                 complete the Data Summary Sheet which includes each of the
                 following scientists/philosophers:

              Democritus
              John Dalton (Atomic Theory)
              J.J. Thomson (Cathode Ray Tube experiment and Plum Pudding Model)
              Robert Millikan (Oil Drop Experiment)
              Ernest Rutherford (Gold Foil Experiment)
              Max Planck (Quantum theory)
              Albert Einstein (Photoelectric effect)
              Louis DeBroglie (wave nature of matter)
              James Chadwick
              Henri Becquerel
              Marie Curie
              Niels Bohr (Bohr Theory)
              Erwin Schrodinger (Quantum mechanics)
              Werner Heisenberg (Heisenberg Uncertainty Principle)
             2. Prepare a chronological briefing for Democritus by filling in the
                attached Data Summary Sheet. Cite the sources you use directly on
                these sheets. Be sure to write down all the important information
                about your sources so you can cite them properly using APA
                documentation. (Look in your Science Project Packet for information
                on this or use Citation Machine)

             3. Prepare a timeline which presents in chronological order and
                represents accurately the time elapsed between discoveries. (Paper will
                be provided.) The timeline should include the date, a picture of the
                scientist who made the discovery, and a short description of the
                discovery. In addition pictures of the equipment used in the
                experiment and/or a picture of the model should be included (if
                applicable).

             4. Prepare a bibliography using APA format to identify the sources that
                you consulted to prepare your Summary Sheet and timeline.
