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

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.

The following assessments were shared by teachers implementing the NGSS.  Many of these are drafts and should be used accordingly.  Feel free to improve these assessments or contribute your own.  Learn more here.

ELA/Literacy

• SL.11-12.5 - Make strategic use of digital media (e.g., textual, graphical, audio, visual, and interactive elements) in presentations to enhance understanding of findings, reasoning, and evidence and to add interest.

Mathematics

• HSN-Q.A.1 - Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays. 

• HSN-Q.A.2 - Define appropriate quantities for the purpose of descriptive modeling. 

• HSN-Q.A.3 - Choose a level of accuracy appropriate to limitations on measurement when reporting quantities. 

• MP.4 - Model with mathematics.
