ESSENTIAL QUESTION: How are electrons arranged in atoms:
LEARNING TARGET: Identify the metallic elements by their characteristic colors in a flame test.
BENCHMARKS: SC.912.P.8.5
LEARNING OBJECTIVES: Students will be able to:
-explain that when electrons transition to higher energy levels they absorb energy, and emit energy when they transition to lower energy levels.
-Data chat
BELL RINGER - Read background info and develop a problem statement.
VOCABULARY: energy, ground state, excited state, emission spectra, photon, Planck’s constant, quantum, quantum mechanical model, electron configuration, atomic orbital, energy levels, Aufbau Principle, Pauli Exclusion Principle, Hund’ Rule
HOME LEARNING: notebook update
AGENDA
WHOLE GROUP
Students were asked to read the introduction for the lab as their bell ringer, in order to develop a problem statement.
HL 4 was collected and reviewed.
Students set up their lab notebooks for the Flame Test lab. Students then completed the lab portion of the lab. We will write up the remainder of the lab next class.
