BIG IDEA: Covalent and ionic bonds are not completely separate ideas; they lie on a continuum. Polar covalent bonds are in between the two. Can you explain what a polar covalent bond is?
1. Warm-up: a. What does the dot represent in a Lewis dot structure? b. What does a line represent in a structural formula? c. Explain how an ionic bond forms.
2. Go over new homework, collect old homework.
3. Finish Notes #10: Molecules, Bonding, Formulas, and Structures.
4. Do Dots, Dots (pgs. 29-30).
5. Do worksheet, pg. 87-94. Read Polar Bears and Penguins cartoon WITH students.
4. Go over Big Idea and review homework assignment.
Homework: 1. Identify the variables in your new Quarter Project, and write a clear, detailed, precise procedure. 2. Re-read the Polar Bears and Penguins cartoon with someone; explain to them the difference between an ionic bond, a covalent bond, and a polar covalent bond. Have them write out your explanation and sign it.
