Matter and Its InteractionPS1

  • 1

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

  • 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. 7.PS1.2

  • 3

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

  • 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

  • 6

    Construct, test, and modify a device that releases or absorbs thermal energy by chemical processes to solve a problem.*7.PS1.6

EnergyPS3

  • 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.7.PS3.1

  • 2

    Develop or modify a model to describe that when objects interacting at a distance change their arrangement, different amounts of potential energy are stored in the system.7.PS3.2

From Molecules to Organisms: Structure and FunctionLS1

  • 5

    Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.7.PS3.5

  • 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

    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.7.LS1.7

Ecosystems: Interactions, Energy, and DynamicsLS2

  • 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

  • 2

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

  • 3

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

  • 4

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

  • 5

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

Earth and Human ActivitiesESS3

  • 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

  • 3

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

  • 4

    Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth’s systems.*7.ESS3.4

  • 5

    Obtain, evaluate, and communicate evidence of the factors that have caused changes in global temperatures over the past century.7.ESS3.5
