Convection currents are observed in a container of water on a hot plate and are related to other convection currents.
For the Teacher:
For the Students:
Convection currents can occur in any fluid, such as air or a liquid. When a fluid heats up, it expands, making it less dense and therefore lighter than the fluid around it. Warm fluids rise while cold fluids sink, setting up a circular pattern of flow toward and away from a heat source until all of the fluid reaches the same temperature.
