If you don't get along with someone, it's said that the two of you are like oil and water. Why is this? Explore the phenomenon and explain the phrase in one resource! Science superstars first observe samples of oil and water together....

Observe how molecules with hydrophilic and hydrophobic regions move in a mixture of oil and water, and pay attention to changes in potential energy over time. Move and rotate the molecules to see how they interact with their surrounding...

Mix polar and nonpolar molecules together and observe changes in potential energy.

Select an oil or water environment for molecules and observe how they are affected by interactions with their environment and each other.

Media-rich lesson in which learners discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...
