MS-PS1-2 | Chemical Reactions · NYS standard · Grade 8 test questions
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.

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.
