MS-PS1-2 | Chemical Reactions
Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
Clarification statement: Examples of chemical reactions could include burning of a wooden splint, souring of milk and decomposition of sodium bicarbonate.
Assessment boundary: Assessment is limited to analysis of the following properties: density, melting point, boiling point, solubility, flammability, color change, gas production and odor.
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 four levels.

NGSS Dimensions
Performance expectation MS-PS1-2 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Analyzing and Interpreting Data
- Analyze and interpret data to determine similarities and differences in findings.
- PS1.A: Structure and Properties of Matter
- (NYSED) Each substance has characteristic physical and chemical properties (for any bulk quantity under given conditions) that can be used to identify it.
- PS1.B: Chemical Reactions
- Substances react chemically in characteristic ways. When substances react, the atoms that make up the molecules rearrange, forming new substances with different properties.
- Patterns
- Macroscopic patterns are related to the nature of microscopic and atomic-level structure.
