Physical Sciences
 Electricity and magnetism are related
effects that have many useful applications in
everyday life. As a basis for understanding this
concept:
 Students know how to design and
build simple series and parallel circuits by
using components such as wires, batteries,
and bulbs.
 Students know how to build a
simple compass and use it to detect magnetic
effects, including Earth's magnetic field.
 Students know electric currents
produce magnetic fields and know how to
build a simple electromagnet.
 Students know the role of
electromagnets in the construction of
electric motors, electric generators, and
simple devices, such as doorbells and
earphones.
 Students know electrically
charged objects attract or repel each other.
 Students know that magnets have
two poles (north and south) and that like
poles repel each other while unlike poles
attract each other.
 Students know electrical energy
can be converted to heat, light, and motion.
