Practice: Ecosystems and Biomes: Who Depends on Whom workbook

SC.7.8.4.d Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

Lessons: How Plants Make Food: Photosynthesis and Respiration (How does energy from the Sun move through a whole ecosystem?)

Practice: How Plants Make Food: Photosynthesis and Respiration workbook

SC.7.8.4.e Construct an argument supported by evidence that changes to physical or biological components of an ecosystem affect populations.

Lessons: Ecosystems and Biomes: Who Depends on Whom (What happens to a population when food runs out?, How can we protect an ecosystem's services?) (partly)

Practice: Stone, Bamboo and Storms: Building in Vietnam workbook · Grade 4 Rocks and Minerals

SC.7.13.5.b Construct a scientific explanation based on evidence for how the uneven distributions of Earth’s mineral, energy, and groundwater resources are the result of past and current geoscience processes.

Lessons: Our Changing Planet: Resources and Human Impact (Where does your stuff come from?) (partly)

Practice: Our Changing Planet: Resources and Human Impact workbook

SC.7.13.5.c Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth’s systems.

Lessons: Our Changing Planet: Resources and Human Impact (Do more people always use more resources?) (partly)

Practice: Our Changing Planet: Resources and Human Impact workbook

SC.7.14.6.a Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales.
