Physical Science

Life Science

Earth & Space Science

Physical Science

MS-PS1-1

Model the atoms in simple molecules and in extended structures such as crystals.

MS-PS1-2

Use data on properties such as density, melting point and solubility to decide whether a chemical reaction happened.

MS-PS1-3

Explain how synthetic materials, such as plastics and medicines, are made from natural resources and affect society.

MS-PS1-4

Model how adding or removing thermal energy changes particle motion, temperature and state of a substance.

MS-PS1-5

Model how atoms are rearranged but not created or destroyed in a chemical reaction, so total mass is conserved.

MS-PS1-6

Design and test a device that releases or absorbs thermal energy through a chemical process, such as a hand warmer.

Life Science

MS-LS1-6

Explain how photosynthesis cycles matter and moves energy into and out of organisms.

MS-LS1-7

Model how food is broken down and rearranged in cellular respiration to release energy and build new molecules.

MS-LS2-1

Use data to explain how the amount of resources affects individual organisms and populations in an ecosystem.

MS-LS2-2

Explain patterns of interactions among organisms in ecosystems: competition, predation and mutually beneficial relationships.

MS-LS2-3

Model how matter cycles and energy flows among producers, consumers and decomposers in an ecosystem.

MS-LS2-4

Argue from evidence that changes to physical or living parts of an ecosystem affect its populations.

MS-LS2-5

Evaluate competing design solutions for keeping biodiversity and ecosystem services healthy.

Earth & Space Science

MS-ESS2-1

Model the cycling of Earth's materials and the energy that drives the rock cycle.

MS-ESS2-2

Explain how geoscience processes at very different time and size scales have changed Earth's surface.

MS-ESS2-3

Use fossil, rock and seafloor data as evidence of past plate motions.

MS-ESS3-1

Explain how geoscience processes cause the uneven distribution of minerals, energy and groundwater resources.

MS-ESS3-2

Use data on natural hazards to forecast future events and inform technologies that reduce their effects.
