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.

A lab activity that introduces chromatography using markers, plus water and acetone as the solvents. Students will take measurements to compare the mobile and stationary phases of the inks, and find the polarity of the inks and solvents....

Media-rich lesson in which students 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...
