Clarification Statement - S.MS.PS.1.8.CS:
Emphasis should be on analyzing the physical changes that occur as mixtures are formed and/or separated. Examples of common mixtures could include salt water, oil and vinegar, and air.

Assessment Boundary - S.MS.PS.1.8.AB:
Assessment is limited to separation by evaporation, filtration and magnetism.

Science and Engineering Practices - 6-8.SEP3.1:
Plan an investigation individually and collaboratively, and in the design: identify independent and dependent variables and controls, what tools are needed to do the gathering, how measurements will be recorded, and how many data are needed to support a c

Science and Engineering Practices - 6-8.SEP3.2:
Collect data to produce data to serve as the basis for evidence to answer scientific questions or test design solutions under a range of conditions.

Disciplinary Core Ideas - S.MS.PS.1.8.DCI:
PS1.A: Structure and Properties of Matter •(NYSED) Mixtures are physical combinations of one or more samples of matter and can be separated by physical means.

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