Your teacher places a beaker of water onto a hot plate. He then adds rice to the beaker. The rice swirls around in the hot water. How does this demonstrate convection currents? How do you predict the rice will move?

• The rice will move in a circular pattern due to convection currents.

• The rice will sink to the bottom and stay there.

• The rice will float on the surface without moving.

• The rice will dissolve in the water.
