Learners can use this web-based activity to study solutions, as far as the intermolecular attractive forces that allow or do not allow a solvent to dissolve in a solute. Also discussed includes the solubility rule "like dissolves like"...

A tutorial on covalent bonds and intermolecular forces. A good summary weak forces, including Van der Waals forces and an excellent illustration showing the relative strengths of different forces and bonds.

Through a combination of an interactive demonstration and guided inquiry, students learn the basic nature of surface tension in liquids.

Learn the definitions of a solution, solute, and solvent. Understand how molarity is used to quantify the concentration of solute, and comcalculations related to molarity.

Cut various sections of a substance in this simulation to observe how the substance will crack and fracture at a molecular level.
