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: Atomic structure reteach
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: HL 7
AGENDA
WHOLE GROUP
We reviewed the focus calendar.
The bell ringer was to complete a reteach activity. Since it will serve as a graded assignment, it will not be posted here.
Home learning 7 was explained and distributed. You can find it below.
Answers will be on your own paper.
Students then reviewed the exam by getting into small groups and discussing answers before sharing out to the class.
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.
