Convective Heating

Class practical: Observing convection currents in a beaker of water.

Practical Activity 14-16

Class practical: Visualizing convection currents in air.

Class practical: Watching convection currents in water.

Practical Activity 14-16

Conduction is the way in which energy is transferred (through heating by contact) from a hot body to a cooler one (or from the...

Teaching Guidance 11-14 14-16

The purpose of this activity is to provide a clear demonstration of convection currents.

Classroom Activity 11-14

The purpose of this demonstration is to show the build-up of convection currents of warm air in a room.

Classroom Activity 11-14

Let's think about conduction in solids first. Here each particle vibrates but ends up going nowhere over the longer term. This...

Physics Narrative 11-14

The paper starts to spin because the heat of your hand heats up the air. This sets up a convection current in the air which...

Enrichment Activity 5-11 11-14

Hot water is less dense than cold water so it rises into the top bottle while the cold water sinks into the bottom bottle...

Enrichment Activity 5-11 11-14

The spiral should start to spin slowly. The radiator raises the temperature of the air around it, so the particles move more...

At home 11-14 14-16

Show that if hot water is below cold water, they mix, but if the situation is reversed they do not. Students can use their...
