Oklahoma 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 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.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 broken down and rearranged through chemical reactions to form new molecules that support growth and/or release of energy as 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 or modify 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 in 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 patterns of data related to 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 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
