| Description | This activity is an easy way to demonstrate the fundamental properties of polar and non-polar molecules (such as water and oil), how they interact, and the affect surfactants (such as soap) have on their interactions. Students see the behavior of oil and water when placed together, and the importance soap (a surfactant) plays in the mixing of oil and water—which is why soap is used every day to clean greasy objects, such as hands and dishes.

This activity is recommended for all levels of student, grades 3-12, as it can easily be scaled to meet any desired level of difficulty. |
