Make an Underwater Volcano
Convection currents are a tough subject to teach and to understand, but this science demo makes it a heck of a lot easier. Almost everyone will have these materials to do the science experiment in their home.
Materials
Food coloring
A small piece of aluminum foil
Small flask (or glass)
Large beaker (0r glass)
How does this experiment relate to science?
This discrepant event shows how convection currents work. A convection current is the way that heat rises and falls in liquids and gases. Some classic examples of convection currents are hot air balloons, wind, and a pool that is hotter at the surface and cooler at the bottom. The hot water in my demo rises and is displaced by the colder water.
Higher-Level Questioning
What happens with the heat from a volcano at the bottom of the ocean?
How do you get a hot air balloon back down to the ground?
