Next Generation Science Standards
NGSS.MS-LS. LIFE SCIENCE
MS-LS1. From Molecules to Organisms: Structures and Processes - Students who demonstrate understanding can:
MS-LS1-1. Conduct an investigation to provide evidence that living things are made of cells; either one cell or many different numbers and types of cells.
MS-LS1-2. Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function.
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.DCI. Disciplinary Core Ideas
LS1.A: Structure and Function
LS1.A:1. All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular). (MS-LS1-1)
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.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)
MS-LS4. Biological Evolution: Unity and Diversity - Students who demonstrate understanding can:
MS-LS4.CC. Crosscutting Concepts
MS-LS4.CC.1.2. Graphs, charts, and images can be used to identify patterns in data. ,
MS-LS4.DCI. Disciplinary Core Ideas
LS4.A: Evidence of Common Ancestry and Diversity
LS4.A:2. Anatomical similarities and differences between various organisms living today and between them and organisms in the fossil record, enable the reconstruction of evolutionary history and the inference of lines of evolutionary descent. (MS-LS4-2)
LS4.A:3. Comparison of the embryological development of different species also reveals similarities that show relationships not evident in the fully-formed anatomy. (MS-LS4-3)
LS4.C:1. Adaptation by natural selection acting over generations is one important process by which species change over time in response to changes in environmental conditions. Traits that support successful survival and reproduction in the new environment become more common; those that do not become less common. Thus, the distribution of traits in a population changes.
