Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
Clarification statement: Emphasis is on the law of conservation of matter and on physical models or drawings, including digital forms, that represent atoms.
Assessment boundary: Assessment does not include the use of atomic masses, balancing symbolic equations, or intermolecular forces.

Performance Level Descriptions
Every Grade 8 Science Test question on MS-PS1-5 is written to match one of the performance level descriptions (PLDs) below.
Level 1: Given a model showing a chemical reaction, identify evidence that proves the total number of atoms is conserved. Spring 2026 · Q26 Spring 2026 · Q42 Spring 2025 · Q25 Spring 2024 · Q51
Level 2: Given a model, describe how the total number of each type of atom does not change in a chemical reaction and/or that mass is conserved. Sample · Investigating Chemical Reactions Q3
Level 3: Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.
Level 4: Develop and use a model (including balanced equations and/or atomic masses) to describe how the total number of each type of atom does not change in a chemical reaction and because of this, mass is conserved.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-PS1-5.
This section could be expanded upon. You can help out by adding to this section.
NGSS Dimensions
Performance expectation MS-PS1-5 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- Developing and Using Models
- Develop a model to describe unobservable mechanisms.
Disciplinary Core Ideas
- PS1.B: Chemical Reactions
- (NYSED) Substances react chemically in characteristic ways. When substances react, the atoms that make up the molecules rearrange, forming new substances with different properties.
- The total number of atoms does not change in a chemical reaction and thus mass is conserved.
Crosscutting Concepts
- Energy and Matter
- Matter is conserved because atoms are conserved in physical and chemical processes.
