3. Big Idea #3
Changes in matter involve the rearrangement and/or the reorganization of atoms and /or the transfer of electrons.

4. Enduring Understanding A
Chemical changes are represented by a balanced chemical equation that identifies the ratios with which reactants and products form

5. Enduring Understanding B
Chemical reactions can be classified by considering what the reactants are, what the products are, or how they change from one into the other. Classes of chemical reactions include synthesis, decomposition, acid-base, and oxidation-reduction reactions.

6. Enduring Understanding C
Chemical and physical transformations may be observed in several ways and typically involve a change in energy.
