Lesson 6: Ionic Equations

• —Hook: Pictures of hard water build up/stains; discussion of what’s going on
• Content:—Reactions in solutions, total ionic equation and net ionic equation
  • Video: Keep Your Eyes on the Ions

• —Total/Net ionic equation race relay
  • In groups, compete with other groups to solve problems one after the after

—Consolidation:

• Exit slip: individually solve a total/net ionic equation problem and submit
• Homework: Practice problem/worksheets

Other Teaching Ideas:

• Experiment: Pick one of the following methods for removing hard water build-up, explain the chemistry behind it and how well it worked:

1) Vinegar 2)Vinegar & baking soda 3) Lime-Away 4) CLR
