This Boiling Point of Polar and Non-Polar Substances interactive also includes:
Go to extremes to illustrate boiling point! Junior chemists explore the effects of heating and cooling on polar and non-polar substances. The interactive allows users to raise and lower the temperature, set specific temperatures, and slow the motion of the molecules individuals observe.

Instructional Ideas
- Plan an inquiry project around the interactive that teaches the differences between polar and non-polar molecules
- Have the class identify temperatures where phase changes appear to occur
Classroom Considerations
- Make sure students are comfortable with the states of matter and phase changes, as these are key concepts observed in the interactive
Pros
- Two temperature controls allow users to make observations at specific temperatures as well as during periods of heating and cooling
- Slow motion helps to give learners a clearer picture of molecular interactions
Cons
- None
