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.
