South Carolina Grade 7 science standards

7-ESS3-1 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

7-ESS3-3 Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.

Lessons: Our Changing Planet: Resources and Human Impact (How can a town use less and waste less?) (partly)

Practice: Our Changing Planet: Resources and Human Impact workbook

7-ESS3-4 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

7-ESS3-5 Ask questions to clarify evidence of the factors that have impacted global temperatures over the past century.

Lessons: Climate Clues (Is this winter colder than when your grandparents were kids?, What can a tree ring tell us?) (partly)

Practice: Climate Clues workbook

7-LS1-6 Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.

Lessons: How Plants Make Food: Photosynthesis and Respiration (Where does a tree's mass come from?, What happens to the food a plant makes?)

Practice: How Plants Make Food: Photosynthesis and Respiration workbook

7-LS1-7 Develop a model to describe how food molecules in plants and animals are rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.

Lessons: How Plants Make Food: Photosynthesis and Respiration (What happens to the food a plant makes?)

Practice: How Plants Make Food: Photosynthesis and Respiration workbook

7-LS2-1 Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.

Lessons: Ecosystems and Biomes: Who Depends on Whom (What happens to a population when food runs out?)

Practice: Ecosystems and Biomes: Who Depends on Whom workbook

7-LS2-2 Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.

Lessons: Ecosystems and Biomes: Who Depends on Whom (Are living things competitors, predators or partners?)

Practice: Ecosystems and Biomes: Who Depends on Whom workbook

7-LS2-3 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

7-LS2-4 Construct an argument supported by empirical 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: Ecosystems and Biomes: Who Depends on Whom workbook

7-LS2-5 Evaluate competing design solutions for maintaining biodiversity and ecosystem services.

Lessons: Ecosystems and Biomes: Who Depends on Whom (How can we protect an ecosystem's services?) (partly)

Practice: Ecosystems and Biomes: Who Depends on Whom workbook

7-PS1-2 Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.

Lessons: Kitchen Chemistry (Is it a new substance?, Can red cabbage tell acid from base?)

Practice: Kitchen Chemistry workbook

7-PS1-5 Develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved.

Lessons: Kitchen Chemistry (Where does the mass go?)

Practice: Kitchen Chemistry workbook

7-PS3-1 Construct and interpret graphical displays of data to describe the proportional relationships of kinetic energy to the mass of an object and to the speed of an object.

Lessons: Forces and Motion: Crash, Push and Stop (How fast is a toy car really going?, Why does a heavier cart hit harder?) (partly)

Practice: Forces and Motion: Crash, Push and Stop workbook
