Form 2 have been studying plate tectonics in geography.
After initial investigations into Pangea and evidence of continental drift (while also discovering that continents are drifting at about the same rate that our fingernails grow!), it was time for a practical demonstration of how convection currents in the mantle are the driving force behind the movement.
What better way of doing so than with continents of powdered drinking chocolate and milky magma?
As the 'magma' is heated and convection currents develop, so the chocolate 'Pangea' is ripped apart and so plate boundaries form.
And what to do with the materials once finished?
Why, drink them, of course! Cheers.
