This Dissolving Experimental interactive also includes:
Why does like dissolve like? While in many cases opposites attract, the same cannot be said for chemistry! Solution scholars take an up-close look at the dissolving process with a customizable interactive. The resource allows users to change the polarity of two different groups of molecules so they can observe the result as they interact.

Instructional Ideas
- Instruct the class to experiment with different levels of polarity and record the outcomes
- Have pupils brainstorm possible identities for the molecules they create, using the polarity meter as a guideline
Classroom Considerations
- Briefly discuss polarity and intermolecular forces before you introduce the resource
- Don't use the fast forward feature if you plan to have learners study individual interactions
Pros
- Individuals can shade molecules to reflect their levels of polarity, which helps students tell them apart during their observations
- The user can select fewer options to create simpler reactions for basic solubility studies
Cons
- None
