Serc: Mn Step: Solutions: Solubility and Miscibility
For this activity, students will test the solubility and miscibility of various substances in water, and explain the chemistry involved. They will also be given a solid and a liquid and asked to predict what will happen when each is...
Khan Academy
Khan Academy: Molarity
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.

Middle School Chemistry: Lesson Plans: Why Does Water Dissolve Salt?
Young scholars 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.
