Clarification Statement - S.5.PS.3.1.CS:
Emphasis should be on plants converting light energy by photosynthesis into usable energy. Examples of models could include diagrams and flow charts.

Science and Engineering Practices - 3-5.SEP2.4:
Use models to describe phenomena

Disciplinary Core Ideas - S.5.PS.3.1.DCI:
PS3.D: Energy in Chemical Processes and Everyday Life •The energy released [from] food was once energy from the sun that was captured by plants in the chemical process that forms plant matter (from air and water). LS1.C: Organization for Matter and Energy Flow in Organisms •Food provides animals with the materials they need for body repair and growth and the energy they need to maintain body warmth and for motion. (secondary to 5-PS3-1)

Crosscutting Concepts - CC5.3:
Energy can be transferred in various ways and between objects.
