Polar and Non-Polar Interface

This Polar and Non-Polar Interface interactive also includes:

Why is there so much frozen water at Earth's poles? Because water is a polar molecule! Young scientists observe polar molecules moving in a mixture of oil and water. They see the changes in potential energy in the hydrophilic and hydrophobic regions.

Instructional Ideas
  • Discuss the changes in potential energy as the simulation runs
  • Explain the difference in the speed of movement between the oil and the water
Classroom Considerations
  • Relies on prior knowledge of polar molecules and potential energy
  • Allows pupils to move and rotate molecules to increase the challenge of the simulation
  • Requires very little class time
  • None
