We began the class period by discussing questions students had about Lessons 17-19. The whiteboard work is shown below:
We extended our learning about ions to the study of ionic compounds, reviewing the Lesson 20 PowerPoint which included the vocabulary terms of cation and anion and learning about how different numbers of anions and cations combine by following the Rule of Zero Charge. Students worked on the Lesson 20 Worksheet and for homework should complete Lesson 20 textbook questions #1-7 and read Lesson 21 in the textbook.
