  • Read below for some date changes! I'm delaying the unit project and lab report due dates because I am also delaying the test date! The new test date is the Wednesday 11/26/2014 (the day before Thanksgiving break).
  • Finish the Flame Test Lab in your lab notebook.
    • Make sure you have filled in the rest of the chart! - we did this IN class!!!
    • Make sure to answer all discussion questions! - this should be done already since it was assigned on Wednesday. I will be checking for CONTENT not prep!!
  • Finish the Atomic Spectra Lab in your lab notebook.
    • Make sure to answer all pre-lab questions. - I will be checking for CONTENT not prep!!
      • You can now answer all the questions we skipped because we learned all the math.
        • speed of light = (wavelength) * (frequency)
          • you know speed of light and you know the wavelengths of all the colors.
        • energy = (Plank's constant) * (frequency)
          • Planck's constant stays the same (6.63*10^-34) and you found frequency using the previous equation.
    • Finish all the data chart! - I will be checking for CONTENT not prep!!
      • Make sure that you have shown work somewhere in your lab notebook.
    • Make sure to answer all discussion questions! - I will be checking for CONTENT not prep!!
      • the first discussion question can be googled.
    • Make sure you have attached the entire packet into your lab notebook. I will check for your data table!
Some Dates to Remember:
  • Discussion Questions to both Flame Test Lab AND Atomic Spectra Lab due Monday (11/24/2014)!
    • You will hand in your lab notebooks and I will grade your DQs for content, and give back your lab notebooks on Tuesday so you can complete the Flame Test Lab Report due after we get back from Thanksgiving Break.
      • make sure to attach your Atomic Spectra Lab Packet into your Lab Notebook!!
      • IF YOU NEED HELP WITH THE PRELAB QUESTIONS FOR ATOMIC SPECTRA LAB, PLEASE COME TO ZERO PERIOD MONDAY!!!!
  • Unit Exam Wednesday (11/26/2014) - not the previous date (11/25/2014)
    • subatomic particles and their corresponding charges
    • definition of isotopes
      • calculating the weighted average mass of elements using the idea of isotopes
    • electron configuration
      • spdf (Aufbau Principle)
      • short-hand (dash-form)
      • ground state
      • excited state
    • light emission
      • how, in terms of energy, excited state and ground state
    • history of the evolution of the theory of the atomic model
      • Dalton's billiard ball model
      • JJ Thomson's plum pudding model (cathode ray experiment)
      • Rutherford's model (gold foil experiment)
      • Bohr's solar system model
      • Electron Cloud model - orbitals
  • Final Draft of project due Monday (12/1/2014)!! Refer to Project Website (CLICK)
  • Flame Test Lab Report due in class on Wednesday (12/3/2014)!! Remember to attach your rubric to the lab report!
    • CLICK HERE for the Lab Report Guidelines
      • it's helpful to read and annotate the rubric before starting your lab report!
