Science AIMS Review
Electricity and Magnetism
Magnets

Opposites attract

Like repels
The force between two
magnets depends on
how close they are.

Electricity

Electricity flowing through a circuit can
produce light, heat, sound, and magnetic
effects
Electrical Circuits

Series circuit - connected along a single
path, so the same current flows through
all of the components
If the current is stopped at
any of the bulbs, none of
the light bulbs will work.

Parallel circuit - Current can flow through
each of the bulbs without
first having to flow through
any others. If any of the
bulbs fail the others will still
work as current can still
flow through the rest of the
circuit.
Conductors

Allow electricity to flow through them
Insulators

Items that restrict the flow of electricity
