Apply scientific ideas about magnets to solve a problem through an engineering design project (e.g., constructing a latch to keep a door shut, creating a device to keep two moving objects from touching each other such as a maglev system).*

Scientific and Engineering Practices

Constructing Explanations and Designing Solutions


Students know:
  • Magnetic forces between a pair of objects do not require that the objects be in contact with each other.
  • The sizes of the forces in a magnetic situation depend on the properties of the objects, the distances apart, and their orientation relative to each other.


Students are able to:
  • Define a problem that can be solved with magnets.
  • Apply scientific ideas about magnets.
  • Solve a problem with scientific ideas about magnets through an engineering design project.


Students understand that:
  • Scientific discoveries about the natural world, such as magnets, can often lead to new and improved technologies, which are developed through the engineering design process.
