HS-PS1-4: Total Bond Energy Change in Chemical Reactions

Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy. 

Clarification Statement: Emphasis is on the idea that a chemical reaction is a system that affects the energy change. Examples of models could include molecular-level drawings and diagrams of reactions, graphs showing the relative energies of reactants and products, and representations showing energy is conserved.

Assessment Boundary: Assessment does not include calculating the total bond energy changes during a chemical reaction from the bond energies of reactants and products.
