This general tutorial begins with an explanation of the polarity of the water molecule and the effects this polarity has on the properties of water. Goes on to introduce organic molecules and has a thourough tutorial on the third page.

In this learning module from The Concord Consortium, students will investigate how polar and nonpolar regions in big molecules interact to result in certain shapes and properties for those molecules.

Explore the chemical properties involved in surface tension.

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...
