Instructional Ideas

• Make a handout for pupils to follow as they complete the simulation
• Bring different scents for classes to explore in the classroom

Classroom Considerations

• Individuals need a CK-12 account to access their materials
• The challenge me questions do not belong with this simulation

Pros

• Provides a molecular explanation for each scent
• CK-12 website allows teachers to create classes and assign materials after creating an account

Cons

• None
