Instructional Ideas

• Link the lesson to the spread of smells at different times of the year
• Discuss the way sensors work, often measured in ppm

Classroom Considerations

• Relies on prior knowledge of diffusion

Pros

• Simulation translates into four languages for English learners
• Works well as a whole class demonstration, small group computer lab simulation, or even in a flipped classroom

Cons

• None
