**********ANNOUNCEMENT!!!!!!!*************
The grading scale for the second grading period, and those beyond has been changed. You received the new grading scale. It is to be taped/glued over the old scale in your class syllabus. Remember, the grading scale now is:
CATEGORY BASIS FOR GRADE
Home learning 20%
Laboratory write-ups (wet labs and virtual labs) 5%
Notebook (including classwork) 30%
Reports/Projects 5%
Assessments (exams, exit slips, etc.) 30%
Differentiated Instruction Assignments 10%
Total 100%
Be sure to act accordingly as you complete and submit your assignments!
In addition, all graded assignments must be submitted by Wednesday, 20 January, NO EXCEPTIONS!!!!!
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: Complete the handout on Lewis Dot Structures
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 8 and study for chemical bonding assessment
AGENDA
WHOLE GROUP
We reviewed class correlations and focus calendar tie-ins.
The bell ringer was to complete Lew dot structures for hydrogen, dihydrogen, oxygen, dioxygen, and water.
Students then received HL 8, which can be found below. Answers on your own paper.
This is HL 8. Place answers on your own paper.
Students spent the remainder of class time reviewing information on intramolecular and intermolecular bonding, via Khan Academy. If you do not have your user name and password, you may email me for them. Once on the site, search for chemical bond and complete the videos. The more points you accrue, the better your grade!
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.
