MS-PS1 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.

MS-PS2 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.

MS-PS3 Energy

  • MS-PS3-1 Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.

  • MS-PS3-3 Apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.

MS-PS4 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.

  • MS-PS4-3 Integrate qualitative scientific and technical information to support the claim that digitized signals are a more reliable way to encode and transmit information than analog signals.

MS-LS2 Ecosystems: Interactions, Energy, and Dynamics

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

MS-LS4 Biological Evolution: Unity and Diversity

MS-ESS2 Earth's Systems

MS-ESS3 Earth and Human Activity

MS-ETS1 Engineering Design
