Define it!
Hot, hot, hot
Energy Transfers
A little of this and that
100
Bouncing on a trampoline
What is gravitational, elastic and motion energy?
100
Stored energy
What is energy available to make things happen but is not bringing about change at that moment?
100
The definition of a conductor.
What is a material that heat energy can transfer through efficiently?
100
The energy transfers in a solar propeller.
What is light -> electricity -> motion? (sound may also be present with the motion)
100
The transfer of heat energy through materials is called this.
What is conduction?
200
A lamp with the light on
What is light and electrical energy?
200
Energy in Action
What is energy that is bringing about change?
200
The definition of an insulator.
What is a material that slows the transfer of heat energy?
200
The energy transfers in the pop-up frog.
What is motion -> elastic -> motion -> gravitational?
200
True or False. Energy moves from place to place.
What is TRUE? Energy CAN move from place to place.
300
An apple
What is chemical energy?
300
Energy
What is something that can make things happen?
300
True or False? Cold moves to warm.
What is FALSE? The heat energy will transfer to an area that is colder. "Cold" simply lacks heat energy.
300
The definition of a machine.
What is a device that helps people harness (use) energy transfers to perform a particular task?
300
The tool used for measuring temperature.
What is a thermometer?
400
A furnace
What is heat energy? (gas and electric energy could also be present)
400
Energy Transfer
What is when energy moves from one object or place to another or change from one form to another?
400
True or False. Copper is a good conductor.
What is TRUE? (Think of our butter lab!)
400
The energy transfers in the magic ball.
What is motion (touching the ball) -> electrical -> sound and light (the sound DOES NOT cause the light; the light DOES NOT cause the sound)?
400
True or false. Plastic is a good conductor.
What is FALSE? It is a good insulator.
500
The wind
What is motion energy?
500
Gravitational Energy
What is energy stored in objects that are in a position to fall?
500
Explain how clothes keep you warm.
What is clothes are poor conductors- they do not allow heat energy to pass through them well. Therefore, they are insulators. They slow the transfer of heat energy away from your body. The more layers of clothing you have, the harder it will be for heat to escape. Clothes doesn't really keep the cold out; they keep the heat in.
500
True or False. Heat energy can only be transferred when two objects touch.
What is FALSE? Heat energy can be transferred when objects are near each other or even across the room from each other.
500
True or False. Leaving your back door open in the winter allows cold energy to move in and chill your house.
What is FALSE? Leaving your door open allows heat energy to escape. Remember, heat energy moves to cooler areas. "Cold" is just the absence of heat energy.
