MS-LS1-7
Food molecules, growth, and energy
Performance expectation
Develop a model to describe how food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
Clarification
Emphasis is on molecules being broken apart and put back together, with energy released in the process.
Assessment boundary
Assessment does not include details of the chemical reactions for photosynthesis or respiration.
