Sound Carries Energy
To quickly move back and forth repeatedly.
What is to vibrate?
When light bounces off materials, we say it does this.
What is 'reflect'?
Energy transferred to an object as heat can make materials move so fast, it also produces this.
What is light?
The interactions between moving charges.
What is electricity?
A common source of energy to produce steam is ___.
What is burning fuel?
(accept fossil fuel or similar source)
When you blow on a mouth piece or pluck a string, you make it vibrate, which transfers energy to ______________. This produces sound.
What is 'surrounding air'?
(air is fine)
When light carries energy and transfers it, three things can happen: it can reflect off objects, pass through objects or the object does this.
What is 'absorb light'?
Engine that uses steam to move some of its parts.
What is steam engine?
A flow of electric charge. We use this to carry energy to machines.
What is electric current?
When we say energy is neither created or destroyed, we say it is this.
A common object that uses an electric current to transfer energy to air, and thus produce sound.
What is a speaker?
A tool made of thin layers of different materials that transfer energy carried by light to an electric current. The top layer lets light pass through and traps the light. A middle layer absorbs the light.
The fan-like blades of a spinning wheel.
What is a turbine?
A device that uses electric current to produce motion is this.
What is a motor?
When electric currents flow through a filament, the energy is converted into this and this.
What is heat and light?
Any order accepted.
A speaker uses this shaped part to transfer energy to the air in order to produce a sound.
What is 'cone shaped'?
Accept cone
Thin, coiled wire that converts some energy into light.
What is a filament?
Energy of heat causes the motion of an object because the more hot gas that flows past the turbine in a steam engine, the ___the turbine moves.
What is faster?
Materials that allow electric current to flow through them are called this.
What are conductors?
A system that includes a complete pathway through which electric current flows from an energy source to its components.
What is an electric circuit?
Electric charges can form an electric current when these types of charges move in the same direction.
What is like charges?
What is sun or sunlight?
An electric stove can change energy carried by an electric current into heat because the burner is made of this material.
What is metal?
What is insulator?
A collection of parts working together.
What is a system?
