We’ll investigate factors affecting solubility by designing an experiment, then performing it and reporting on it.  Here are the rubrics that will be used to guide this. FINAL Rubric design  FINALRubric DCP   FINAL Rubric CE

This link has some useful information to help you explain your findings.

We’ll learn about saturated solutions and what actually happens when a substance dissolves.  We’ll also make some predictions as to the kinds of substances that can dissolve in water.
