MS-PS1-8 | Mixtures
Plan and conduct an investigation to demonstrate that mixtures are combinations of substances.
Clarification statement: 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: Assessment is limited to separation by evaporation, filtration and magnetism.
Note: this is a NYSED-specific performance expectation that is different from the Next Generation Science Standards.
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-PS1-8 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Planning and Carrying Out Investigations
- Plan and conduct an investigation to demonstrate that mixtures are combinations of substances.
- PS1.A: Structure and Properties of Matter
- Mixtures are physical combinations of one or more samples of matter and can be separated by physical means.
- Patterns
- Macroscopic patterns are related to the nature of microscopic and atomic-level structure.
