MS-PS1-7
Use evidence to illustrate that density is a property that can be used to identify samples of matter.
Clarification statement: Emphasis should be on students measuring the masses and volumes of regular and irregular shaped objects, calculating their densities, and identifying the samples of matter.
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.

NGSS Dimensions
Performance expectation MS-PS1-7 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Engaging in Argument from Evidence
- Construct and present oral and written arguments supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem.
- 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.
- Patterns
- Macroscopic patterns are related to the nature of microscopic and atomic-level structure.
