Lesson 5
- Recap from last class: (10 min)
- Why didn’t the plum pudding model explain?
- What did John Dalton originally think an atom looked like?
- Which model accounts for electron energy levels? - Hand out lesson 2 student notes, periodic tables, and key terms sheet (2 min)
- You can choose whether you have your students fill out the key terms sheet themselves or simply read over it to refresh themselves on the terms (time is variable)
- Go through Google slide notes - the calculating subatomic particles part only (20 mins)
- Complete subatomic particles worksheet (30 mins)
- Continue through notes (20 mins)
- Have students practice some basic Bohr diagrams (atoms and ions) on whiteboards or paper (rest of class)
Lesson 6
- Hand out whiteboards and have students draw Bohr diagrams: (20 mins)
- Carbon atom
- Carbon ion
- Nitrogen ion
- Helium atom
- Helium ion
- Chlorine atom
- Chlorine ion
(correct students' drawings as they go) - Hand out lesson 3 student notes (2 mins)
- Go over Google slide notes (20 minutes)
- Hand out Bohr and Lewis flowchart for students to reference + go over it with them. (10 min)
- Have students complete a Bohr and Lewis practice assignment (rest of class)
Lesson 7-8
- Recap from last class: (10 min)
- What is the difference between an ionic compound and a covalent compound?
- How do you draw a Bohr diagram of an ionic compound vs a covalent compound?
- What are valence electrons? How many does oxygen have? - Hand out lesson 4 student notes (2 min)
- Go through Google Slide notes (20 mins)
- Hand out electron configuration practice and give students time to work on it (30-40mins)
- When students complete the first assignment, I usually give them an additional assignment of reading and questions out of their textbook (rest of class)
