NGSS 5-LS
From Molecules to Organisms: Structures and Processes (5-LS1)
Students who demonstrate understanding can: Support an argument that plants get the materials they need for growth chiefly from air and water. (5-LS1-1) [Clarification Statement: Emphasis is on the idea that plant matter comes mostly from air and water, not from the soil.] Disciplinary Core Idea; Organization for Matter and Energy Flow in Organisms (LS1.C) Cross-Cutting Concept: Energy and Matter Matter is transported into, out of, and within systems. (5-LS1-1) Science and Engineering Practices Engaging in Argument from Evidence Engaging in argument from evidence in 3–5 builds on K–2 experiences and progresses to critiquing the scientific explanations or solutions proposed by peers by citing relevant evidence about the natural and designed world(s). Support an argument with evidence, data, or a model. (5-LS1-1) |
Ecosystems: Interactions, Energy, and Dynamics
(5-LS2) Students who demonstrate understanding can: Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment. (5-LS2-1) [Clarification Statement: Emphasis is on the idea that matter that is not food (air, water, decomposed materials in soil) is changed by plants into matter that is food. Examples of systems could include organisms, ecosystems, and the Earth.] [Assessment Boundary: Assessment does not include molecular explanations.] Disciplinary Core Ideas: Interdependent Relationships in Ecosystems (LS2.A) The food of almost any kind of animal can be traced back to plants. Organisms are related in food webs in which some animals eat plants for food and other animals eat the animals that eat plants. Some organisms, such as fungi and bacteria, break down dead organisms (both plants or plants parts and animals) and therefore operate as “decomposers.” Decomposition eventually restores (recycles) some materials back to the soil. Organisms can survive only in environments in which their particular needs are met. A healthy ecosystem is one in which multiple species of different types are each able to meet their needs in a relatively stable web of life. Newly introduced species can damage the balance of an ecosystem. (5-LS2-1) Cycles of Matter and Energy Transfer in Ecosystems (LS2.B) Matter cycles between the air and soil and among plants, animals, and microbes as these organisms live and die. Organisms obtain gases, and water, from the environment, and release waste matter (gas, liquid, or solid) back into the environment. (5-LS2-1) Cross-Cutting Concept: Systems and System Models A system can be described in terms of its components and their interactions. (5-LS2-1) Science and Engineering Practices Developing and Using Models Modeling in 3–5 builds on K–2 models and progresses to building and revising simple models and using models to represent events and design solutions. Develop a model to describe phenomena. (5-LS2-1) Connections to Nature of Science: Science Models, Laws, Mechanisms, and Theories Explain Natural Phenomena Science explanations describe the mechanisms for natural events. (5-LS2-1) |
