Polyatomic Ions

For lesson 22, students continued to explore ionic bonds, this time in the context of polyatomic ions.  We worked through the Lesson 22 PowerPoint and then students used the class period to practice creating and naming polyatomic ions and their chemical formulas by playing two different card games and then recording their learning on the Lesson 22 Worksheet.

Update: October 31, 2018: Notes from the Lesson 21/22 review are posted below.  Apologies to my 6th period students who lost an entire class period of learning after the three fire alarm pulls that occurred during that period, disrupting an hour of class for nearly 1200 students at our school.

Students are encouraged to review lesson content by watching the videos below:
