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.
Assessment
What assessment of HS-PS1-12 might look like on a NY state exam.
| Exam | Cluster | Question |
|---|---|---|
| August 2026 | Safe Transport of Drinking Water | Question 45 |
| June 2026 | Clock Reaction | Question 31 |
| All About Aluminum | Question 44 | |
| All About Aluminum | Question 45 | |
| Sample clusters (Spring 2025) | Smartphone Chemistry | Question 5 |
Performance Level Descriptions
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of five levels.
☐
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
