Ever wonder why oil and water don't mix? Or why washing butter off of your hands is difficult? A video explores the different types of molecules, reviews charge and geometric asymmetry, and covers why water is one of the best molecular structures on Earth.
- 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
- Requires access to the Internet, a projection system, and a computer to complete the activity
- 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
- There is an inaccurate image at 3:37; you must turn on annotations to see the corrections
