Students will use the terms solute and solvent in describing a solution. They will sketch a solution at the particle level and design and conduct an experiment to determine the factors (e.g., agitation, particle size, temperature)...

Understand how temperature, pressure, and the presence of other solutes affect the solubility of solutes in solvents.

Students have the opportunity to study examples and worked out example problems to further their understanding of chemical solution concentration.

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

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.

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.
