Notes for teachers:
I space out these assignments over 3 days.
Day 1: Notes Examples 1-2 with Practice #1: Problems 1-3
Day 2: Notes Examples 3-4 with Practice #1 Problems 4-5
Day 3: Notes Example 5 with Practice #2 (all)
I go over the answers to Practice #1 at the start of Days 2 & 3
Suggested materials for the demos
Notes for teachers:
To save time, I have students record the 4 evidences of chemical change for homework the day before I carry out the demos. I'll make a copy of the Slides that only includes Slides 1 & 2 to post for students to reference.
The video is an older version that uses potassium iodide and lead (II) nitrate for Reaction 4.
Lead (II) iodide is a pain to dispose of so I switched the reaction for the in-person demos
For the in-person demos, Reaction 4 uses sodium carbonate and calcium chloride.
Notes for teachers:
I typically only teach net ionic equations to my advanced chemistry classes. For my on-level classes, I'll have my students write the complete balanced equation for precipitation reactions in lieu of writing net ionic equations.
