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
PLDs communicate the knowledge and skills expected of students to demonstrate proficiency in each Learning Standard. NYS assessments classify student performance into one of four levels.
Resources
Examples and discussion of resources for the learning, teaching, and assessment of MS-LS1-7.
This section could be expanded upon. You can help out by adding to this section.
Assessment
What assessment of MS-LS1-7 might look like on a NY state exam.
NGSS Dimensions
Performance expectation MS-LS1-7 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
- Developing and Using Models
- Develop a model to describe unobservable mechanisms.
- 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)
- Energy and Matter
- Matter is conserved because atoms are conserved in physical and chemical processes.
