Science Education Standards:

Benchmarks

By the end of the 5th grade, students should know that

  • Without touching them, a magnet pulls on all things made of iron and either pushes or pulls on other magnets. 4G/E2
  • Without touching them, an object that has been electrically charged pulls on all other uncharged objects and may either push or pull other charged objects. 4G/E3*

By the end of the 8th grade, students should know that

  • Electric currents and magnets can exert a force on each other. 4G/M3
  • A charged object can be charged in one of two ways, which we call either positively charged or negatively charged. Two objects that are charged in the same manner exert a force of repulsion on each other, while oppositely charged objects exert a force of attraction on each other. 4G/M5** (BSL)
