Matter and Its Interactions

MS-PS1-3 Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
- Synthetic materials (8-G.8)
MS-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.
- Count atoms and molecules in chemical reactions (8-G.2)
- Calculate amounts of reactants or products in chemical reactions (8-G.3)
MS-PS1-6 Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
- Describe energy changes in chemical reactions (8-G.4)

Motion and Stability: Forces and Interactions

MS-PS2-1 Apply Newton's Third Law to design a solution to a problem involving the motion of two colliding objects.
MS-PS2-2 Plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.

Waves and Their Applications in Technologies for Information Transfer

MS-PS4-1 Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave.
MS-PS4-2 Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
- Transmission, reflection, and absorption of waves (8-N.6)
MS-PS4-3 Integrate qualitative scientific and technical information to support the claim that digitized signals (sent as wave pulses) are a more reliable way to encode and transmit information.

From Molecules to Organisms: Structure and Processes

MS-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.
- The chemistry of cellular respiration (8-Q.2)

Biological Unity and Diversity

MS-LS4-1 Analyze and interpret data for patterns in the fossil record that document the existence, diversity, extinction, and change of life forms throughout the history of life on Earth under the assumption that natural laws operate today as in the past.
- Compare ages of fossils in a rock sequence (8-V.2)
MS-LS4-2 Apply scientific ideas to construct an explanation for the anatomical similarities and differences among modern organisms and between modern and fossil organisms to infer ancestral relationships.
- Evaluate anatomical evidence of evolution (8-U.6)
- Compare fossils to modern organisms (8-V.1)

Earth's Place in the Universe

MS-ESS1-4 Construct a scientific explanation based on evidence from rock strata for how the geologic time scale is used to organize Earth's geologic history.
- Compare ages of fossils in a rock sequence (8-V.2)

Earth's Systems

MS-ESS2-1 Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process.
MS-ESS2-2 Construct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales.
MS-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.

Earth and Human Activity

MS-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.
- Petroleum formation and distribution on Earth (8-BB.1)
- Renewable and nonrenewable energy resources (8-BB.2)
MS-ESS3-2 Analyze and interpret data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects.
- Analyze natural hazard maps (8-II.1)
MS-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.
- Evaluate claims about natural resource use: groundwater (8-BB.3)
- Evaluate claims about natural resource use: fossil fuels (8-BB.4)
