Instructional Ideas

• Create collaborative groups; assign a different molecule for each group to build a model of, research, and create a presentation
• Hold contests challenging the accuracy and speed at building molecular models

Classroom Considerations

• Expects previous work with molecular models

Pros

• Connects the model to the chemical formula
• Offers the lesson on a free DVD resource

Cons

• None
