Class practical: Observing convection currents in a beaker of water.
Class practical: Visualizing convection currents in air.
Class practical: Watching convection currents in water.
Conduction is the way in which energy is transferred (through heating by contact) from a hot body to a cooler one (or from the...
The purpose of this activity is to provide a clear demonstration of convection currents.
The purpose of this demonstration is to show the build-up of convection currents of warm air in a room.
Let's think about conduction in solids first. Here each particle vibrates but ends up going nowhere over the longer term. This...
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...
Hot water is less dense than cold water so it rises into the top bottle while the cold water sinks into the bottom bottle...
The spiral should start to spin slowly. The radiator raises the temperature of the air around it, so the particles move more...
In this demonstration students see that if hot water is below cold water, they mix, but if the situation is reversed they do...
