MS-PS1-2
Evidence of chemical reactions
Performance expectation
Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
Clarification
Examples may include common reaction systems, with evidence drawn from characteristic properties.
Assessment boundary
Assessment is limited to density, melting point, boiling point, solubility, flammability, and odor.
