Convection Currents

Convection Currents

The lesson on 11-10-14 was on convection currents.  The students talked about convection currents that are all around us and what those look like.  We then continued that conversation into the convection currents that are believed to be inside the Earth and assisting in plate movement.  The students then were engaged in an activity that allowed them to see the movement of substances and how they vary according to the substances temperature.  The students were guided in some of the experiment and then allowed to come up with three of their own variations on water temperatures to test.  Off to the side and below are  the before and after pictures of the experiments.
