HS-PS3-1 →

Use evidence to illustrate that some chemical reactions involve the transfer of electrons as an energy conversion occurs within a system.

Clarification statement: Evidence could include half-reactions, net ionic equations, and electrochemical cells to illustrate the mechanism of electron transfer.

Assessment boundary: Assessment is limited to completing and/or balancing oxidation and reduction half-reactions. Energy conversions are limited to qualitative statements

Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.

Performance Level Descriptions

Every Regents exam question on HS-PS1-12 is written to match one of the performance level descriptions (PLDs) below.

Level 1: Use provided information to identify a reaction or a component(s) in a model that illustrates the transfer of electrons within a system. June 2026 Question 44
Level 2: Use or provide evidence to demonstrate that some chemical reactions involve the transfer of electrons within a system. August 2026 Question 45
Level 3: Use a model (e.g. electrochemical cell) or information that provides evidence to make a claim or support the argument that some chemical reactions involve the transfer of electrons as an energy conversion occurs within a system. June 2026 Question 45
Level 4: Use evidence to illustrate that some chemical reactions involve the transfer of electrons as an energy conversion occurs within a system.
Level 5: Evaluate claims and analyze evidence to communicate that some chemical reactions involve the transfer of electrons as an energy conversion occurs within a system.
Notice: PLD levels!

NGSS Dimensions

Performance expectation HS-PS1-12 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices
  • Engaging in Argument from Evidence
    • Evaluate the claims, evidence, and reasoning behind currently accepted explanations or solutions to determine the merits of arguments.
Disciplinary Core Ideas
  • PS1.B: Chemical Reactions
    • (NYSED) Oxidation-reduction reactions are the prevailing source of power for many of today's modern conveniences.
Crosscutting Concepts
  • Energy and Matter
    • The total amount of energy and matter in closed systems is conserved.
    • Changes of energy and matter in a system can be described in terms of energy and matter flows into, out of, and within that system
