Grade 7

Earth's Systems

  • 7-ESS2-1.

    Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process.7-ESS2-1

  • 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.7-ESS3-1

Structure and Properties of Matter

  • 7-PS1-1.

    Develop models to describe the atomic composition of simple molecules and extended structures.7-PS1-1

  • 7-PS1-3.

    Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.7-PS1-3

  • 7-PS1-4.

    Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.7-PS1-4

Matter and Energy in Organisms and Ecosystems

  • 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.7-LS1-6

  • 7-LS1-7.

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

  • 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.7-LS2-1

  • 7-LS2-3.

    Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.7-LS2-3

  • 7-LS2-4.

    Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.7-LS2-4

Human Impacts

  • 7-ESS3-2.

    Analyze and interpret data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects.7-ESS3-2

Chemical Reactions

  • 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.7-PS1-2

  • 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.7-PS1-5

  • 7-PS1-6.

    Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.7-PS1-6

Interdependent Relationships in Ecosystems

  • 7-LS2-2.

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

  • 7-LS2-5.

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

History of Earth

  • 7-ESS2-2.

    Construct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales.7-ESS2-2

  • 7-ESS2-3.

    Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions.7-ESS2-3

Engineering, Technology, and Applications of Science

  • 7-ETS1-1.

    Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.7-ETS1-1

  • 7-ETS1-2.

    Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.7-ETS1-2

  • 7-ETS1-3.

    Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.7-ETS1-3

  • 7-ETS1-4.

    Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.7-ETS1-4
