Instructional Ideas

• Stop the video periodically and give pairs of learners compounds or molecules to draw Lewis structures from

Classroom Considerations

• Classroom needs access to the Internet, a projection system, and a computer
• Video assumes learners understand valence electrons

• This video is hosted on YouTube

Pros

• Video models how to draw Lewis dot diagrams or Lewis structures
• The resource discusses how models have inaccuracies but are still beneficial for learning

Cons

• None
