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.
- Discuss the changes in potential energy as the simulation runs
- Explain the difference in the speed of movement between the oil and the water
- 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
