Next Generation Science Standards
NGSS.MS-LS. LIFE SCIENCE
MS-LS1. From Molecules to Organisms: Structures and Processes - Students who demonstrate understanding can:
MS-LS1.CC. Crosscutting Concepts
MS-LS1.CC.4. Energy and Matter
MS-LS1.CC.4.1. Matter is conserved because atoms are conserved in physical and chemical processes.
MS-LS1.CC.4.2. Within a natural system, the transfer of energy drives the motion and/or cycling of matter.
MS-LS2. Ecosystems: Interactions, Energy, and Dynamics - Students who demonstrate understanding can:
MS-LS2-3. Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
MS-LS2.DCI. Disciplinary Core Ideas
LS2.B: Cycle of Matter and Energy Transfer in Ecosystems
LS2.B:1. Food webs are models that demonstrate how matter and energy is transferred between producers, consumers, and decomposers as the three groups interact within an ecosystem. Transfers of matter into and out of the physical environment occur at every level. Decomposers recycle nutrients from dead plant or animal matter back to the soil in terrestrial environments or to the water in aquatic environments. The atoms that make up the organisms in an ecosystem are cycled repeatedly between the living and nonliving parts of the ecosystem. (MS-LS2-3)
