Electricty
a form of energy
made when tiny parts
move around in an
atom; energy that can
produce light, heat,
sound and magnetism
harness
to make use of (the
power of something)
for a purpose
needs
things people must
have to live. Humans
need water to live
wants
things people would
like to have. I want a
Porsche to drive.
Electric
current
amperes
(amps)
Static
Electricity
the movement of
electrons through
matter
a measure of the
amount of current
in a wire
Electricity caused by a
build up of negative
charges in one place and
positive charges in
another
Lightning
A flash of light caused
by the release of static
electricty between two
clouds or from a cloud
to the Earth
Atom
tiny particles
that make up
matter
nucleus
Center of an
atom
proton

has a positive
charge
neutron
a particle that
has no charge
electron
particle that has
a negative
charge
Circuit
A closed path that
allows an electric
current to flow
Series
Circuit
A singular path
that allows an
electric current to
flow
Parallel
circuit
A path with one or
more branches that
allows an electric
current to flow
Battery
An energy source
for a device
Conductor
a material, usually a
metal, that allows
an electric current
to flow (transmits
electricity)
Insulator
Material that does
not allow an electric
current to flow
through it
Magnet
something that
can attract
other substances
(like iron and steel)
magnetism
a force that
pushes and pulls
certain metals
magnetic
field
an area around a
magnet where
magnetism can
be felt
attract
to pull toward one
another, as
opposite poles of
two magnets pull
toward one
another
repel
to push away, as
similar poles of
two magnets
push away from
one another
north pole
the end of a
magnet where lines
of force flow out
south pole
the end of a
magnet where
lines of force flow
in
power lines
power cables that
carry high-voltage
electricity
transformer
a device that
changes the
voltage of an
electric current
voltage
the amount of push
that gets an electic
current moving
electromagnet
a magnet that can
be turned on or off
by sending
electricity through
metal
electromagnetism
a combined force of
electricity and
magnetism
