Instructional Ideas

  • Show water and oil mixed in a beaker; have pairs of learners explain why these two substances repel each other
  • After the video, have learners tweak their explanations using knowledge of polar and non-polar molecules 
Classroom Considerations

  • Requires access to the Internet, a projection system, and a computer to complete the activity
Pros

  • Includes simple, relatable examples of polar and non-polar interactions (oil and water and butter on your hands with water) to help the concept come alive for learners
  • Video explores why water is so good at so many different things
Cons

  • There is an inaccurate image at 3:37; you must turn on annotations to see the corrections
