  1. Atomic Models Webquest

  2. Introduction • For thousands of years, people have wondered and thought about what makes up the world around us. • About 200 years ago, scientists had an idea that all of matter could be broken down into similar, basic particles. • They named the particle “atom,” which means “indivisible, or not able to be divided.” • Throughout the following 200 years, scientists’ understanding of the atom has changed • More scientific tests to support, refine, or refute atomic models • Advances in technology have allowed scientists to gather more data

  3. Task • You will be assigned to a specific scientist for this webquest and will be given special tasks and resources that can be used to complete the task. You may work with a partner as you gather information and create your project. Next week, you will present your project to the class. • The information you present to the class should include: • Scientist’s name • Time during which the scientist lived and worked • A description of previous understandings of the atom • A description of this scientist’s model of the atom • An explanation of what led to this model

  4. Task, continued Format Your project may take any format that seems appropriate for your scientist and model. Some examples include: • PowerPoint presentation • Art project (of model) and presentation • Scientist portrayal (Dress up and act as if you are the scientist.) Scientists • Dalton • Thomson • Rutherford • Bohr • de Broglie and Shroedinger

  5. Dalton • Step 1: Read page 9 in our textbook. • Step 2: Visit the website http://www.iun.edu/~cpanhd/C101webnotes/composition/dalton.html • Step 3: Visit the website http://dl.clackamas.edu/ch104-04/dalton%27s.htm • Step 4: Visit the website http://library.thinkquest.org/15567/bio/dalton.html • Step 5: Create your project. Use your notes and your text to help you. • Finished early? Play these games: • Atom Basics Quiz • Element Picture Quiz

  6. Thomson • Step 1: Read about Dalton’s model on page 9 in your textbook. • Step 2: Read about Thomson’s model on pages 10 – 12 in your textbook. Take notes as you read. • Step 3: Visit the website http://www.chemheritage.org/discover/online-resources/chemistry-in-history/themes/atomic-and-nuclear-structure/thomson.aspx • Step 4: Visit the website http://www.aip.org/history/electron/jjelectr.htm • Step 5: Create your project. Use your notes and your text to help you. • Step 6: Finished early? Play these games: • Atom Basics Quiz • Element Picture Quiz

  7. Rutherford • Step 1: Read about Dalton’s model on page 9 in your textbook. • Step 2: Read about Thomson’s model on pages 10 & 11. Rutherford was one of Thomson’s students, so Thomson’s work was a large influence on Rutherford. • Step 3: Read about Crookes’ tests and Rutherford’s model on pages 12-15. • Step 4: Visit the website http://www.chemheritage.org/classroom/chemach/atomic/rutherford.html • Step 5: Visit the website http://www.daviddarling.info/encyclopedia/R/Rutherfords_experiment_and_atomic_model.html. Read the sections entitled “Testing the Currant Bun” and “Rutherford’s New Model.” • Step 6: Create your project. Use your notes and text to help you. • Step 7: Finished early? Play the quizzes in Step 6 on the previous page.

  8. Bohr • Step 1: Read pages 12-15 about Rutherford’s model of the atom. • Step 2: Visit the website http://csep10.phys.utk.edu/astr162/lect/light/bohr.html. Read the first section on “The Planetary Model of the Atom.” • Step 3: Visit the website http://abyss.uoregon.edu/~js/glossary/bohr_atom.html. • Step 4: Visit the website http://videos.howstuffworks.com/hsw/5787-niels-bohrs-atomic-model-video.htm and watch the video on atomic models. • Step 5: : Create your project. Use your notes and your text to help you. • Step 6: Finished early? Play these games: • Atom Basics Quiz • Element Picture Quiz

  9. de Broglie and Schroedinger • Step 1: Visit the website http://improbable.org/era/physics/atom.html. Read all the scientists’ ideas. You don’t need to understand Schroedinger’s equation ~ just that he had a mathematical understanding of the atom. • Step 2: Read pages 16-17 in our text. Which ideas most resemble your scientists’? • Step 3: Visit the website http://www.colorado.edu/physics/2000/quantumzone/debroglie.html. Be sure to use the interactive model near the bottom of this page. • Step 4: Visit the website http://www.colorado.edu/physics/2000/quantumzone/schroedinger.html • Step 5: Create your project. Use your notes and your text to help you. • Step 6: Finished early? Play these games: • Atom Basics Quiz • Element Picture Quiz
