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.
