Develop a model to describe how food molecules are rearranged through chemical reactions to release energy during cellular respiration and/or form new molecules that support growth as this matter moves through an organism.
Clarification statement: Emphasis is on describing that molecules are broken apart and put back together and that in this process, energy is released.
Assessment boundary: Assessment does not include details of the chemical reactions for respiration or synthesis.

Performance Level Descriptions
Every Grade 8 Science Test question on MS-LS1-7 is written to match one of the performance level descriptions (PLDs) below.
Level 1: Given a model, identify the new molecules that form when food molecules are rearranged through chemical reactions to release energy during cellular respiration or identify the new molecules that support growth as this matter moves through an organism. Spring 2025 · Q22 Spring 2024 · Q39
Level 2: Given a model, identify evidence that shows how food molecules are rearranged through chemical reactions to release energy during cellular respiration and/or form new molecules that support growth as this matter moves through an organism.
Level 3: Develop a model to describe how food molecules are rearranged through chemical reactions to release energy during cellular respiration and/or form new molecules that support growth as this matter moves through an organism.
Level 4: Develop multiple models to describe how food molecules are rearranged through chemical reactions to release energy during cellular respiration and describe how new molecules are formed that support growth as this matter moves through an organism.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-LS1-7.

NGSS Dimensions
Performance expectation MS-LS1-7 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
- LS1.C: Organization for Matter and Energy Flow in Organisms
- Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules, to support growth, or to release energy.
- PS3.D: Energy in Chemical Processes and Everyday Life
- Cellular respiration in plants and animals involves chemical reactions with oxygen that release stored energy. In these processes, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials. (secondary to MS-LS1-7)
Crosscutting Concepts
- Energy and Matter
- Matter is conserved because atoms are conserved in physical and chemical processes.
