500 Students will develop the ability to:
500 1.  Match atomic models with the correct scientist
500 2.  Describe the experiments that led to the discovery of electrons and protons
500 3.  Explain Rutherford's scattering experiment
500 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
500 5.  Determine the number of protons, neutrons and electrons in any isotope using atomic number and mass number
500 6.  Summarize the Starborn article explaining how the various isotopes came to exist in our universe
500 7.  Use isotope abundance calculations to determine the number of old and new pennies in a sealed film canister
500 8.  Explain that atomic mass is a weighted average of the naturally occurring isotopes of an element

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