The Standards

5th Grade

Ecosystems: Interactions, Energy, and Dynamics

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 and Assessment Boundary

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.

Science and Engineering Practices

Developing and Using Models

Modeling in 3–5 builds on K–2 experiences 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)

Common Core State Standards Connections
