Grade 4 - Science - Energy transfer

Front

What is convection?

Back

Convection is the transfer of heat in liquids and gases where warmer areas rise and cooler areas sink, creating a circulation.

Front

What is radiation?

Back

Radiation is the transfer of energy through waves or particles, even across distances, without needing a medium.

Front

What is conduction?

Back

Conduction is the transfer of heat between substances that are in direct contact with each other.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing heat transfer.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily.

Front

How does heat transfer from a fireplace?

Back

Heat transfers from a fireplace mainly through radiation.

Front

What happens to warmer liquids or gases?

Back

Warmer liquids or gases rise, pushing down cooler areas, leading to convection.

Front

What is an example of conduction?

Back

An example of conduction is when a metal spoon gets hot from being in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is the warm air rising from a heater and circulating around a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.
