Video Learning Notes
In this lesson, students develop and use models to understand how matter cycles and energy flows through living and nonliving parts of an ecosystem. They learn that matter is recycled continuously through producers, consumers, and decomposers, while energy flows in one direction from the sun through the ecosystem. Decomposers play a critical role in recycling nutrients, maintaining ecosystem balance. Modeling these processes helps students visualize and explain ecosystem dynamics, meeting NGSS standard MS-LS2-3.
Learning Goals
- Develop a scientific model that illustrates how matter cycles among living and nonliving parts of an ecosystem.
- Describe how energy flows through an ecosystem from producers to consumers and decomposers.
- Explain the role of decomposers in recycling matter back to the environment.
- Identify the boundaries of an ecosystem and describe how matter and energy move across these boundaries.
- Use evidence and observations to support explanations about matter cycling and energy flow in ecosystems.
