Heat on the Move
This type of energy transfer happens through direct contact, like a spoon getting hot in a bowl of soup.
What is conduction?
Sound is produced by this quick back-and-forth motion.
What is a vibration?
This is the very first step of the scientific method where you use your senses to notice something.
What is make an observation?
This unit, abbreviated as "amps," measures the flow of electric current.
What are amperes?
This is where electricity is produced before it travels through power lines to your home.
What is a power plant?
This is the transfer of heat through the movement of liquids or gases, such as warm air rising to the ceiling.
What is convection?
Because sound is produced by moving particles of matter, it is considered this type of energy.
What is kinetic energy?
This is an educated guess or a "testable statement" that you form after asking a question.
What is a hypothesis?
This is the term for a material that electricity flows through easily.
What is a conductor?
These "invisible walls" hidden in our home's real walls are what electricity travels through to reach our outlets.
What are circuits?
This is energy that travels through space as waves, allowing you to feel the heat of a campfire without touching it.
What is radiation?
Sound cannot travel through a vacuum because it needs this to travel through.
What is matter (or a medium)?
You must do this to find out if your hypothesis is correct or incorrect.
What is test your hypothesis (or conduct an experiment)?
Resistance in a circuit, like that found in a light bulb, is measured in these units.
What are ohms?
This part of an audio speaker is actually an electromagnet that vibrates to create sound waves.
What is the voice coil?
This type of material, like rubber or plastic, slows down or stops the flow of heat.
What is an insulator?
Sound waves are created when vibrating objects do this to air particles.
What is squeeze them together and spread them out?
After you collect your data, you reach this final step to explain what you learned.
What is draw a conclusion?
Batteries are used in a circuit as this type of "source" to move electrons.
What is a voltage source?
Energy of motion is used to turn this part of a generator to produce a current.
What is the axle?
These materials, usually metals, allow heat to move through them very easily.
What are conductors?
True or False: The temperature of air particles can change how fast sound waves move.
What is true?
Scientists do this step last to let others know about their findings.
What is communicate results?
This describes a circuit where the path is broken and electricity cannot flow.
What is an open circuit?
This is used to cover wires to keep us safe from electrical currents.
What are plastic insulators?
