Ooooh, practical thinkies

One of the things science students always say, no matter who their teacher is, what year level they're at, whatever, is that they want more practical work.

This is awesome, but also a little problematic for teachers. The reason why I am conflicted over it is twofold. First, by the time I get my grubby little scientific mitts on them, students have usually defined what practical work is in their heads and it is a pretty narrow definition. It almost always includes bunsen burners and WORKSHEETS where you fill in things (like the aim and the method) and there is always a defined end point which you know about going in (because, usually, you've covered the topic in class already and so everyone knows that the candle gets lighter as you burn it). Second, they are often woefully useless at self-preservation and so teachers spend an awful lot of time making sure that the classroom is not set alight and that no one tries to drink the acid.

But we have to perservere with this. Experimentation and investigation are essential (the justification for that is a topic for another day). So, right now, I am devising a block of work around chemistry and skin care that will involve enough practical work to satisfy the most demanding adolescent audience. Even better? There is no set end goal. There are activities on the way, but the final golaposts require creativity, critical thought, and actual original experimentation.

Today, I am so happy.
