Students will be able to plan and carry out an investigation to compare the solubility of different substances, and develop and explain a particle-level model to describe the process of dissolving.

Students will be able to develop and explain a particle-level model to describe their observations of water dissolving the colored sugar coating of an M&M. Students will be able to use this model to ...

The dissolution of a gas in water can be regarded conceptually as a two-step process. The first conceptual step is the formation of a cavity in liquid water large enough to accommodate a gas molecule ...
