• Convection

• Conduction

• Radiation

Explanation Slide...

This type of energy transfer is convection. The air is warmed by the fire. The air molecules move more quickly, spread out, become less dense and rise to the top of the cabin. The air cools at the top, molecules slow down and get close together, become more dense and sink.

Multiple Choice

What type of energy transfer happens when you place ice on sprained ankle?

• Convection

• Conduction

• Radiation

Multiple Choice

What type of energy transfer happens when a metal spoon sits in a bowl of hot soup and the spoon gets hot.

• Convection

• Conduction

• Radiation

Explanation Slide...

This type of energy transfer is conduction. The hot soup is directly touching the spoon. The thermal energy is leaving the soup and going into the spoon to warm up the spoon. Energy flows from hot to cold. That is why you need an insulator at the end of the metal spoon so that you do not burn your hand.

• Convection

• Conduction

• Radiation

Explanation Slide...

This type of energy transfer is convection. The burner inside the hot air balloon makes the air hot. The air molecules move quickly and spread out, making the air less dense. The air inside the hot air balloon is less dense than the air outside of the balloon and that is why it rises up into the sky.

Multiple Choice

What type of energy transfer happens when the great ocean conveyor belt moves Earth's water around the globe?

• Convection

• Conduction

• Radiation

Explanation Slide...

This type of energy transfer is convection. The sun heats up water at the equator and travels North in the Gulf Stream. It moves along Europe (the climate is warmer there because of the current) and becomes cold and sinks to the ocean floor. Then the water moves South and goes back down to the Equator to be warmed up again.

Multiple Choice

What type of energy transfer happens when you place food into the microwave to heat it up?

• Convection

• Conduction

• Radiation

Explanation Slide...

This type of energy transfer is radiation. The electromagnetic waves heat the food indirectly. No mass is needed to transfer the energy.

Multiple Choice

The transfer of energy through materials: solid, liquid, gas.

• Conduction

• Convection

• Radiation

Explanation Slide...

In order for conduction to happen, the materials must be in direct contact with the heat source.

Multiple Choice

The transfer of energy through the same materials. This only happens in liquids or gases.

• Conduction

• Convection

• Radiation

Explanation Slide...

Convection happens when fluids (liquids or gases) are heated up. The molecules move faster and spread out, making them less dense. The rise until the start to cool down. The molecules then slow down and stick close together, making them more dense. The cooler molecules sink and the cycle starts again.
