When you incorporate Chemistry into English lessons.
For example, when my teacher was discussing 'The Great Gatsby' and talks about Gatbsy being a bootlegger, I started to work out equations for the hydrolsis of poly- and di- saccharides as well as for the fermentation of glucose. I then drew a diagram of of a distillation apparatus. I then suggested to the teacher that we should produce some ethanol as a class in our double lesson in order to gain some perspective on Gatsby.:grinshak:
Since I am also a physics and maths nerd (No I am not Asian, I'm Italian), I have also managed to incorporate those subjects into English lessons.
To prove that Sally Bowles from the movie Cabaret is a sl*t, I got up a derived an equation to prove that certain regions of her body could be considered a black hole and derived equations to prove that she had her own graviational pull and then did a ratio of her gravitational acceleration to the Earth's.
Good memories
