Today we had a demonstration. Mr. Morrow had beakers of water on a Bunson plate. We waited till they both were almost boiling and then add food coloring to them and put pieces of styrofoam in. The styrofoam moved like the plates do on the convection curets.
My observation was that the food coloring was the magma that the styrofoam was the plates. The food coloring moved in circles. The circles represent the matter the is less dense rise to the top and as it cool it becomes denser and then goes back and is heated again and forced to the top.
We did this demonstration because it gave a a good idea of what convection currents look like. It also helps us understand convection currents better.
