Boiling water.The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion.
Some examples of Convection would be:

1) Boiling a pot of water on the stove
2) 
using a hot radiator to warm the air in a room
3) 
using heated air to make a hot-air balloon rise up into the sky

[ Can choose anyone, there are three ]

Hope this helps!
