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.

Concepts

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
