Learning Goals/Student Objectives
➔ Physical changes involve changes in state or form without creating new substances.

➔ Physical properties change how a bulk-scale substance behaves, but doesn’t change the chemical identity.

➔ Chemical changes produce new substances with different properties.

➔ Chemical changes can be accompanied by a change in state (e.g. precipitation).

➔ The outcomes of chemical reactions relate to valence electron arrangements and periodic trends (e.g. reactivity, electronegativity, etc).

➔ Green Chemistry makes the world safer, cleaner, and better for everyone.
