This Polarity and Attractive Strength interactive also includes:
Teaching intermolecular forces can be quite a stretch! Chemistry scholars experiment with the attractive strength between polar molecules using an interactive resource. Learners test molecules of low, medium, and high polarities by pulling them apart and observing how far the attractive strength reaches between molecules.

Instructional Ideas
- Ask students to describe how difficult it was to separate each pair of molecules
- Reverse the process! Have the class gradually move each molecule toward one another and describe how quickly or easily the molecules reattached
Classroom Considerations
- Make sure pupils are clear on the differences between polar and non-polar molecules
Pros
- Pulling on the molecules adds a fun element to the lesson
- The behavior of the molecule pairs is very realistic
Cons
- None
