Lesson 7
Polarity & Covalent Molecular Solids
Learning Intention: Justify what causes polarity and how that relates to properties such as melting/boiling points and solubility.
Success Criteria
8. I can explain the properties* of covalent molecular solids.
11. I can explain if a covalent bond will be polar or nonpolar.
12. I can explain if a simple molecule will be polar or nonpolar.
Learning Tasks
Do Now - Complete the Week 9 Check-In on the memo paper. Random Question: Since it's post senior assessment week, what was something positive you learned from the week (aka something you are actually better at than you thought you were) and what's a takeaway lesson that you have learned?
Copy down Ms Garlick's notes on types of bonds.
Test your knowledge on if ionic or covalent bonds will form using the AACT Bonding Stimulation.
Open up the PhET Molecular Polarity simulation, tick bond dipole, partial charges, and bond character. Set surface to electrostatic potential. Then tinker with both the two atoms and three atoms. Each time you learn something new, write it Ms Garlick's piece of paper to show on the screen.
Copy down Ms Garlick's notes on polarity and covalent molecular solids.
Mahi Choice

Teacher Notes
Ideally would have done this as two lessons, but short on time.
