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.
Grade 8 Science Test Questions
Released New York State Grade 8 science test questions that assess MS-PS1-7 are listed here by test and question cluster. Each link opens the question with its answer key.
| Exam | Cluster | Question |
|---|---|---|
| Spring 2026 Grade 8 Test | Acoustic Levitation | Question 8 |
| Spring 2025 Grade 8 Test | Maple Syrup Production | Question 3 |
Performance Level Descriptions
Every Grade 8 Science Test question on MS-PS1-7 is written to match one of the performance level descriptions (PLDs) below.
Level 1: Given an argument, identify the evidence that illustrates that density is a property that can be used to identify a given sample(s) of matter.
Level 2: Given evidence, identify the argument that illustrates that density is a property that can be used to identify a given sample(s) of matter.
Level 3: Use evidence to illustrate that density is a property that can be used to identify samples of matter.
Level 4: Using measurements, calculations and observations as evidence, construct an argument, using density values, that either supports or refutes the identity of various samples of matter.
Resources

NGSS Dimensions
Performance expectation MS-PS1-7 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- 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.
Disciplinary Core Ideas
- 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.
Crosscutting Concepts
- Patterns
- Macroscopic patterns are related to the nature of microscopic and atomic-level structure.
