HS-PS1-12

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.
