Building toward Performance Expectation MS-LS1-3
- Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells.
Disciplinary Core Idea LS1.A: Structure and Function
- In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions.
Reading Addresses Performance Expectation MS-LS2-3
- Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
Disciplinary Core Idea LS2.B: Cycle of Matter and Energy Transfer in Ecosystems
- 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.
Reading Addresses Performance Expectation MS-ESS1-3
- Analyze and interpret data to determine scale properties of objects in the solar system.
Disciplinary Core Idea ESS1.B: Earth and the Solar System
- The solar system consists of the sun and a collection of objects, including planets, their moons, and asteroids that are held in orbit around the sun by its gravitational pull on them.
