Hydrogen Atom Details, Multi-electron Atoms, Excited States, Spectra, and Lasers
UNIT: AP2 Modern Physics
DURATION: 1 period(s)
OBJECTIVES: The student will be able to
* Describe the source of discreet energy levels within atoms, using the hydrogen atom as a (relatively) simple example, and explain the Pauli exclusion principle
* Extend the aforementioned to describe (qualitatively) energy levels within multi-electron atoms, resulting spectra, and the production of light in a laser
ACTIVITIES / PROCEDURES:
* Board presentation with notes and examples
* Multiple representations (graphical and algebraic)
* One-on-one teacher / student instruction during practice session
* Peer teaching / collaboration during practice session
* Class discussion with inquiry method
ASSESSMENT:
* Monitor proficiency during practice session
* Call on students at random or with emphasis on students who may need assistance
* Assign pre-class problem(s) on next day after practice / reflection homework assignment
MATERIALS:
* ActivBoard and chalkboard
* Representative AP Problems
HOMEWORK:
* Pre - Read / Outline Sections 29.5-29.9
* Post - Representative problems from textbook
