MS-PS2 Motion and Stability: Forces and Interactions

  • MS-PS2-3 Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.

  • MS-PS2-4 Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.

  • MS-PS2-5 Conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even though the objects are not in contact.

MS-ESS1 Earth's Place in the Universe

  • MS-ESS1-1 Develop and use a model of the Earth-sun-moon system to describe the cyclic patterns of lunar phases, eclipses of the sun and moon, and seasons.

  • MS-ESS1-2 Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.

  • MS-ESS1-3 Analyze and interpret data to determine scale properties of objects in the solar system.

  • 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 4.6-billion-year-old history.
