4th Grade Physical Science

1. Electricity and magnetism are related effects that have many useful applications in everyday life. As a basis for understanding this concept:

a. Students know how to design and build simple series and parallel circuits by using components such as wires, batteries, and bulbs.

b. Students know how to build a simple compass and use it to detect magnetic effects, including Earth's magnetic field.

c. Students know electric currents produce magnetic fields and know how to build a simple electromagnet.

d. Students know the role of electromagnets in the construction of electric motors, electric generators, and simple devices, such as doorbells and earphones.

e. Students know electrically charged objects attract or repel each other.

f. Students know that magnets have two poles (north and south) and that like poles repel each other while unlike poles attract each other.

g. Students know electrical energy can be converted to heat, light, and motion.
