        1. Investigate whether mass is unchanged when chemical and physical changes take place.
        2. Develop and use models to describe the nature of matter; demonstrate how they provide a simple way to to account for the conservation of mass, changes of state, physical change, chemical change, mixtures, and their separation.
        4. Classify substances as elements, compounds, mixtures, metals, non-metals, solids, liquids, gases and solutions.
