Activity: Basic Modeling of the Dissolving Phenomenon
In this activity, students explore the process of salt dissolving in water using cut-outs of ions and water molecules to model interactions between them.

Solubility, Solute & Solvent, Intermolecular Forces | Middle School, High School
Activity: Advanced Modeling of the Dissolving Phenomenon
In this activity students build a model of sodium chloride based on their own knowledge of ionic compounds. Then they construct a model of the interactions between water and their salt model to develop an understanding of what caused the salt to dissolve. After refining their models based upon class discussions and critiques, students then construct a model of the interaction between salt and a different solvent, alcohol. Using their models, students make predictions as to which solvent (water or alcohol) would be better at dissolving the salt. Finally students design an experiment to test their prediction. As an extension, students are asked to use their solubility models to explain why calcium carbonate will not dissolve in water, even though it is also an ionic compound.
