Next Generation Science Standards
NGSS.MS-LS. LIFE SCIENCE
MS-LS1. From Molecules to Organisms: Structures and Processes - Students who demonstrate understanding can:
MS-LS1-6. Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
MS-LS1-7. 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.
MS-LS1.CC. Crosscutting Concepts
MS-LS1.CC.4. Energy and Matter
MS-LS1.CC.4.2. Within a natural system, the transfer of energy drives the motion and/or cycling of matter.
MS-LS1.DCI. Disciplinary Core Ideas
LS1.B: Growth and Development of Organisms
LS1.B:3. Genetic factors as well as local conditions affect the growth of the adult plant. (MS-LS1-5)
LS1.C: Organization for Matter and Energy Flow in Organisms
LS1.C:1. Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use. (MS-LS1-6)
PS3.D: Energy in Chemical Processes and Everyday Life
PS3.D:1. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen. (secondary to MS-LS1-6)
PS3.D:2. Cellular respiration in plants and animals involve 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)
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.CC. Crosscutting Concepts
MS-LS2.CC.3. Energy and Matter
MS-LS2.CC.3.1. The transfer of energy can be tracked as energy flows through a natural system.
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)
