Additional Info

  • Finish up the POGIL "Isotopes" activity, including the extension.
  • Finish up your Pennium lab, including the histogram. Make sure your axes are nicely labeled and that you have a title. Each penny's mass and year should be shown in a "block" on the histogram, as demonstrated in class.
  • Show work thoroughly on any calculation Qs. For the question about "fractional abundance," list your answer as both as a fraction AND as a percentage. Be sure to explain any answers to questions in complete sentences. You should answer the pre-lab, calculations, and critical thinking Qs on p. 53 AND 54 (not the "going further" though).
  • If you are asked to find the average mass of each isotope, you have to SHOW your work (Q. 3). When you are asked to find the weighted average (Q.4), you need to use your answers from Q. 3 and Q. 2 and show your calculation
