100
What is one way you can create heat?
Rubbing your hands together
100
Give an example of a conductor.
Metal
100
Give an example of an insulator.
Plastic
100
Define energy.
Doing work or making a change to something.
100
How can you create heat using an eraser?
Rub it back and forth on paper quickly.
200
What tool do you use to measure temperature?
Thermometer
200
What is is called when air travels in a circular pattern?
Convection
200
What units is temperature measured using?
Degrees
200
Define thermal energy
The amount of heat in the moving particles of an object.
200
What is the word for the amount of thermal energy in an object?
Heat
300
How are heat and temperature different?
Something can have more or less heat, but have the same temperature, like two pots of water on a stove with different amounts of water inside them.
300
How does the sun warm your skin when you are standing outside?
Radiation
300
When two things touch each other, heat can be transferred by...
Conduction
300
Define convection.
Heat traveling in a circular patter, where warm air rises and cold air sinks.
300
Explain how convection works.
Warm and rises and cold air sinks, so when the air gets warm, it rises to the top of something and the air moves in a circle.
400
Are heat and temperature the same thing? Explain.
No, the amount of heat will be different even if the temperature of two objects is the same.
400
Explain why a plastic spoon stays cool when it is placed in hot water.
It is an insulator.
400
Explain why a metal spoon gets warm when it is placed in warm water.
It is a conductor of heat.
400
Define conduction.
The ability of heat to travel between objects.
400
How can you create heat (explain using science terms)?
You use energy, which makes something get warmer, and creates thermal energy. The thermal energy becomes heat.
500
How does a thermometer work?
The thermometer moves up and down when the particles in the matter move faster or slower.
500
What are the three ways heat can travel?
Radiation, conduction, and convection
500
Why is a greenhouse warm?
It absorbs the radiation from the sun.
500
Define thermal energy.
The amount of heat that is in the moving particles of an object.
500
What is the difference between a conductor and an insulator?
A conductor lets heat travel through easily and an insulator does not allow heat to travel through it easily.
