Transcript
Name _______________________ 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. Document1 Page 1 of 2 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. Document1 Page 2 of 2
