Instructional Ideas
- Conduct a live demonstration of the interaction between oil and water, then use the interactive to illustrate what happened in the flask
- Have the class compare the interactions between water molecules, between oil molecules, and between water and oil molecules
Classroom Considerations
- Consider arranging time for individual computer use so each student can explore the interactive on their own
- Briefly review properties of polar and non-polar molecules before pupils begin
Pros
- The mixture takes a moment to fully separate, just like the actual substances would if students mixed them
- Shading on molecules make them easy for learners to identify and keep track of during the interactive
Cons
- Shows water molecules with two atoms instead of three, which could be confusing
