Don't try this at home

Ben, who teaches math and science to my class, took his lesson outdoors today - it was a balmy -1 degrees outside - and aside from the temperature I was impressed by two things in particular. Firstly, his audience swelled dramatically as a result, which says something about the ratio of students who are actually in the school building when they are meant to be compared with those whose aren't, and secondly...well, there can't be many science lessons that take place with a backdrop like this one!

Oh, and in case you were wondering, in light of the fact that we don't have a cloud of volcanic ash lingering over our part of the world at the moment, Ben was trying to create our own alternative version by dropping increasingly large chunks of sodium into a bowl of water. The end result was pretty impressive and one was left with the thought: just how many outdoor science lessons take place in Iceland?
