Energy Vocabulary, Grade 4
Directions: Prepare the definitions for the following science words.
Add words as needed.

Battery – A source of electricity stored as potential (chemical) energy.

Buzzer – A resistor that transforms electricity into sound (vibrations).

Condensation- A gas (vapor) changing to a liquid when the gas is cooled.


Conductors – Materials that allow energy (electrical energy in this
case) to flow or pass through the material.
Electromagnets – A temporary magnet made by wrapping a nail with a coil
of insulated wire; when electric current passes through the
wire, the nail becomes a magnet.



Energy – The ability to do work or make things move.
Evaporation- A liquid changing into a gas (vapor) when the liquid is
heated.
Freezing- A liquid changing into a solid when the liquid is cooled.
Insulator – Materials that allow energy (electrical energy in this case)
to flow or pass through the material.
Light Bulb – A resistor that transforms electrical energy into light
energy.


Melting- A solid changing into a liquid when the solid is heated.
Motor – A resistor that transforms electrical energy into kinetic
energy (motion).
Resistor- Any device that transforms (changes) electricity into
another form of energy.
Short Circuit – An electrical circuit that has no resistor. This is
dangerous since short circuits, when closed, can produce
a lot of heat.

States of matter - The states of matter are solid, liquid and gas.

Switch, closed - A switch that allows electricity to flow in a circuit.

Switch, open – A switch that does not allow electricity to flow in a
circuit.
