ESSENTIAL QUESTION: Why do electrons emit light energy?
RELEVANCE: How can I use an electron’s movement to determine its element?
NGSSS: SC.912.P.10.1; MAFS.912.N-Q.1.1; LAFS.910.WHST.1
LEARNING OBJECTIVES: Students will be able to:
-conduct an investigation that determines the flame color of metals.
-continue quarterly project how does pH affect plant growth.
BELL RINGER: List the number of valence electrons for elements hydrogen, lithium, sodium, nitrogen, helium, and neon.
VOCABULARY: wavelength, frequency, speed, electromagnetic spectrum, hertz
HOME LEARNING: HL 4 Electron Configuration
AGENDA
WHOLE GROUP
We reviewed the interdisciplinary connections. We will continue writing in depth, including using the claim statement.
Home learning 3 was collected and reviewed. Home learning 4 was distributed. You can find it below.
This is HL 4. Complete, using the following chart as a guide.
Use the information included in this table to help you determine the electron configurations.
We watched the video I Heart Electron Configuration again.
We completed the in depth writing of the Flame Test Lab, using the argument driven inquiry method.
SMALL GROUP/INDEPENDENT PRACTICE/DI
Students who compete work early should go to CK-12.org (log in with username and password) and do the physics simulation light wave.
HOTS:
-Justify why fireworks can allow you to determine the metal salts they contain.
-Speculate as to why light energy is given off when an electron returns to its original energy level and not when it moves up an energy level.
EXIT STRATEGY: completed lab write-up
