Clarification Statement - S.MS.PS.1.2.CS:
Examples of reactions could include burning sugar or steel wool, fat reacting with sodium hydroxide, and mixing zinc with hydrogen chloride.

Assessment Boundary - S.MS.PS.1.2.AB:
Assessment is limited to analysis of the following properties: density, melting point, boiling point, solubility, flammability, and odor.

Science and Engineering Practices - 6-8.SEP4.1:
Analyze and interpret data to determine similarities and differences in findings.

Disciplinary Core Ideas - S.MS.PS.1.2.DCI:
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. (Note: This Disciplinary Core Idea is also addressed by MS-PS1-3.) PS1.B: Chemical Reactions •(NYSED) Substances react chemically in characteristic ways. In a chemical process, the atoms that make up the original substances are regrouped into different particles and these new substances have different properties from those of the reactants.(Note: This Disciplinary Core Idea is also addressed by MS-PS1-3.)

Crosscutting Concepts - CC1.9:
Macroscopic patterns are related to the nature of microscopic and atomic-level structure.
