ESSENTIAL QUESTION: What Keeps Substances Together?
RELEVANCE: The Bonds that Tie
NGSSS: SC.912.P.8.6; MAFS.912.N-Q.1.1; LAFS.910.WHST.1
LEARNING OBJECTIVES: Students will be able to:
-distinguish between ionic, covalent bonds, and metallic bonds and explain how they are formed.
-draw Lewis structures for simple molecules and molecules with multiple bonds.
-continue quarterly project how does pH affect plant growth.
BELL RINGER: Kahoot.it Chemical Bonds
VOCABULARY: anion, cation, chemical bond, conductivity, covalent bond, covalent, bond, delocalized electrons, diatomic molecule, electrolyte, electron dot, electronegativity, formula unit, intermolecular forces, ionic bond, Lewis dot structure, metallic bond, molecule, monatomic ion, oxidation number, polar covalent, polyatomic ion, solubility, structural formula
HOME LEARNING: notebook update
AGENDA
WHOLE GROUP
We reviewed tie ins to the focus calendar.
Students participated in a Kahoot.it on chemical bonds, with the winner receiving a home learning pass.
We reviewed the answers for HL 7.
Students viewed the video Dogs Teaching Chemistry on Chemical Bonds as a way to review chemical bonds. You can find the movie below.
This is the video that reviews chemical bonds.
We completed the notes on chemical bonds, using the slide show that we began on December 14/15 of last year. You can find it in movie form and the link to the actual slide show on that date.
SMALL GROUP/INDEPENDENT PRACTICE/DI
Students who compete work early should go to
70% or higher on pre-test Khan’s academy chemical bonds
less than 70% on pre-test- WGBH PBS Bonding (ionic and covalent)
HOTS:
-What type of bonds would you expect noble gases to form and why?
-Explain why ionic bonds are weaker than covalent bonds. Use your knowledge of solutions in your answer.
EXIT STRATEGY: Three things I learned: two things I found interesting: I question I still have.
