5-LS2 Ecosystems: Interactions, Energy, and Dynamics

5-LS2   Ecosystems: Interactions, Energy, and Dynamics

Students who demonstrate understanding can:

5-LS2-1. Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment. [Clarifcation 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.]
The performance expectations above were developed using the following elements from the NRC document A Framework for K-12 Science Education:

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.

Science Models, Laws, Mechanisms, and Theories Explain Natural Phenomena

  • Science explanations describe the mechanisms for natural events. (5-LS2-1)

Connections to other DCIs in fifth grade:

5.ESS2.A (5-LS2-1); 5.PS1.A (5-LS2-1)

Articulation of DCIs across grade-levels:

Common Core State Standards Connections:

ELA/Literacy -
RI.5.7 Draw on information from multiple print or digital sources, demonstrating the ability to locate an answer to a question quickly or to solve a problem efficiently. (5-LS2-1)
SL.5.5 Include multimedia components (e.g., graphics, sound) and visual displays in presentations when appropriate to enhance the development of main ideas or themes. (5-LS2-1)
Mathematics -
MP.2 Reason abstractly and quantitatively. (5-LS2-1)
MP.4 Model with mathematics. (5-LS2-1)
