[Free Registration/Login may be required to access all resource tools.] In this learning module, students will study water's ability to act as a solvent.

Students identify and control variables to design an experiment to see whether the temperature of a solvent affects the speed at which a solute dissolves.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students expand their study of mixtures to show that solids and gases can also act as solvents. Additionally, they take a look at situations in which...

Students use their own model of a salt crystal and water molecule to show how water dissolves salt. Then, they relate their observations to the structure of salt, water, and alcohol on the molecular level.

Online biology textbook discussing the chemical nature of water, and the importance of its molecular structure to life. Also discusses at length the organic molecules nucleic acids, proteins, lipids, and carbohydrates.

This site gives a good explanation of osmosis and reverse osmosis. Also includes a scientific diagram of the process.
