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 five levels.

Level 4Level 3Level 2Level 1

Plan and conduct multiple scientific investigations to provide evidence that mixtures are physical combinations of substances.

Plan and conduct an investigation to demonstrate that mixtures are combinations of substances.

Conduct a given investigation to provide evidence that mixtures are physical combinations of substances.

Given an investigation and data, identify the substances that were physically combined to create the mixture.

NGSS Dimensions

Performance expectation MS-PS1-8 was developed using the following elements from the NRC document A Framework for K-12 Science Education:

Science and Engineering Practices

• Planning and Carrying Out Investigations
  • Plan and conduct an investigation to demonstrate that mixtures are combinations of substances.

Disciplinary Core Ideas

• 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.

Crosscutting Concepts

• Patterns
  • Macroscopic patterns are related to the nature of microscopic and atomic-level structure.

Connections to Other Standards

MS-PS1-8 connections to ELA, math, and other science standards as outlined by the NYS Education Department:
