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.
Regents Exam Questions
Released New York State Regents exam questions that assess HS-PS1-12 are listed here by exam and question cluster. Each link opens the question with its answer key.
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.
Level 2: Use or provide evidence to demonstrate that some chemical reactions involve the transfer of electrons within a system.
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.
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.

Resources
Examples and discussion of resources for the learning, teaching, and assessment of HS-PS1-12.
This section could be expanded upon. You can help out by adding to this section.
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
