How did chemists' model of the atom develop and change over time?



Early models of the atom
Discovery of the electron and proton
Rutherford's scattering experiment
Size of nucleus vs. atom
Atomic and mass number
Isotopes
Atomic mass




Students will develop the ability to:
1. Match atomic models with the correct scientist
2. Describe the experiments that led to the discovery of electrons and protons
3. Explain Rutherford's scattering experiment
4. Make analogies between submicrosopic and macroscopic using the atomic bowling laboratory experiment to relate the size of a nucleus to the size of an atom
5. Determine the number of protons, neutrons and electrons in any isotope using atomic number and mass number
6. Summarize the Starborn article explaining how the various isotopes came to exist in our universe
7. Use isotope abundance calculations to determine the number of old and new pennies in a sealed film canister
8. Explain that atomic mass is a weighted average of the naturally occurring isotopes of an element





All studnets will:
1. Develop a time line for the history of the atomic theory
2. Relate the atomic bowling activity to Rutherford's scattering experiment
3. Develop an understanding of the relative size of the atom and nucleus through the bowling activity
4. Read the Starborn article and write an abstract of the article
5. Calculate the number of protons, neutrons, and electrons for any given isotope
6. Penny isotope lab activity



Analysis of lab activities
Quizzes and test
Peer check--ability to determine number of subatomic particles and isotope abundance

Assessment is based on a total point system. Lab reports range between 50 and 100 points. Quizzes range between 10 and 25 points. Tests range between 100 and 200 points. Homework ranges between 5 and 15 points. Performance based grading ranges between 5 and 20 points.
