How I teach the nitrogen cycle (without PowerPoint)

The nitrogen cycle is one of my favourite lessons. There's so much to connect to: history and everyday life. But, students need a clear model to understand what's going on, lest it be abstract and meaningless.

I'll show you two models. One for 16–18 and one for 14–18. In this post, I describe how I built the model in a lesson with my 16–18 year olds, while the model for 14–18 can be found at the end.
